300 Win Mag Handloads and Ballistics

208 A-Max Velocity Model 1885

Here's a sample velocity of my favorite 208 A-Max hand load in my Model 1885 rifle.

 

208 A-Max accuracy 3 shot group Model 1885

Here's a 100 yard, three shot group of my 208 A-Max hand load in my Model 1885 rifle with 75.5 Grains of H-1000.

 

208 A-Max and 215 Berger Hybrid three shot groups from 300 win mag Model 1885

Checking the accuracy of my 208 A-Max hand load I also try a 215 Berger Hybrid with the same charge of H-1000 powder. Wow, the point of impact is near identical. This A-Max group is 0.56" and the Berger is 0.74". I'm sure the 215 Hybrid will shoot better I just need to spend a little more time tweaking the load.

Below are my personal favorite loads for my Winchester Model 1885 High Wall in 300 Win Mag. To view the loads you will need to read the warning near the bottom of the page, then accept the warning by checking the box inside the warning.

One of the cool things I like about the Model 1885 is that there are no magazine length restrictions. You will notice that the cartridge overall lengths in my loads are well beyond the listed 3.34" max overall length for the 300 Win Mag.

Using a Sharpie marker on the ogive of the bullets I am able to seat a bullet a little deeper and deeper watching for land marks in the marker on the ogive. Doing this I have seated the 208 A-Max so that it doesn't touch the lands by just a hair. With the 215 Berger Hybrid I also have the ogive really, really close to being in the lands — probably half a hair off the lands.

As I write this I am still working on a 215 Berger Hybrid load. I have it shooting quite well with similar powder charges as the 208 A-Max but I really haven't spent time testing a lot of powder charges. I have just been shooting a load here or there when I have been working on the A-Max load. The 215 Berger Hybrid has just shot well right out of the chute. It is interesting that the point of impact is almost the same with the same powder charge yet two different bullets (see photo on the right).

A few years ago I saw the light on annealing my brass for consistent, accurate hand loads as well as keeping the necks from cracking. I now always anneal my brass every time it's fired.

I noticed visually a lot on inconsistencies in the brass neck thicknesses with the Remington brass I am using for the 300 Win Mag. I purchased a RCBS neck turner and this has greatly helped with improving the accuracy further. Turned necks and annealed brass really help give a very consistent neck tension shot after shot. I'm now a believer in neck turning and will be doing it on all my brass in the future.

Winchester Model 1885 with Talley Base and Rings

This is a good base and ring combo for the Model 1885. It's a Talley system built for Winchester. The draw back with this system is that there is no way to achieve any MOA in the mount. I also recommend lapping your rings once you have this base secured on the rifle.

 

3/4 inch spacer to add length of pull to my Model 1885

Being a tall lengthy guy I always have to add about 3/4" extra length of pull to my rifles to keep the scope off my face when firing the rifle.

I often just cut a piece of oak to fit, oversize two holes through the spacer, and then get longer screws to extend through the recoil pad and spacer.

I hide the ugly, not so perfectly sized spacer with a neoprene stock cover with shell holder.

 

Model 1885 with Weaver bases, Burris Signature Zee Rings and Vortex Viper PST

This shows the rear Weaver base with the Burris Signature Zee Ring. You can see the plastic inserts between the metal ring and scope tube. On this rear ring I have the 10+ spacer on the top and the 10- spacer on the bottom.

 

Leveling scope on Model 1885 High Wall Vortex Level

To help with the really long shots I have installed a Vortex bubble level to help me keep from canting the rifle.

To get everything aligned I use a couple of magnetic levels with perpendicular levels and snap them to the side of the receiver. I then place a picture hanging level on top of the scope cap. Once I have it all level I tighten up the rings and lock the Vortex level in place.

I could probably just use one level on the receiver but I like having the two to make extra sure I have it all lined up.

 

Neoprene Shell holder on Model 1885

I like having a neoprene shell holder that has a flap that can velcro over the shells protecting them from the elements.

I like having shells right on the stock for a quick follow-up shot if necessary.

I have taken double coyotes with a Model 1885 rifle within seconds by having extra shells handy.

 

Model 1885 Velcro lever shut

I have a velcro tie around the stock with one loop over the lever. This keeps the lever from catching on my pack straps and opening the action while I'm out hunting. If I need to cycle the action I am just a second or two from pulling the velcro off the lever.

 

Model 1885 with Picatinny Riser Rail

I tried to get a picatinny rail on the Model 1885. The problem I ran into is that, with the Weaver bases, there was a 42 MOA drop from the rear base to the front base. In this photo I only screwed down the rear Weaver base and then just clamped the front Weaver base into the riser rail to show the height difference from the front to rear on this Model 1885.

 

Model 1885 with picatinny rail

All looks well with this Lion Gears 12 slot riser rail clamped on the Weaver base but if I tightened this down solid the aluminum rail would flex and put torque on the scope. See the photo above this photo that shows the height difference between the front and rear Weaver bases.

Another issue with this system is that even with low Weaver rings I would be mounting the scope approximately 3/8 inch higher than I would like. I would probably need to add something to the comb to keep my shooting form comfortable.

 

Model 1885 Chronograph of 300 Win Mag with 208 A-Max

Here is a sample photo of the chronograph of a 208 A-Max hand load I am working on in my 300 Win Mag Model 1885.

I'm still tweaking this load and will post load data when I have it.

 

Model 1885 Shearing primers

The Model 1885 likes to extrude the primer back into the firing pin hole then the falling block shears it off. The shells on the left are from my Model 1885 rifles showing the sheared primers while the shells on the right are from my X-Bolt and A-Bolt rifles with normal looking primer indents.

With my Model 1885 in 300 Win Mag I have not had any issue with the extruded primer. The primer indention looks perfectly normal.

To prevent the primer from being sheared off and gumming up the firing pin just dry fire the rifle immediately after you fire the rifle and before you open the action. Doing so will indent the primer again and prevent it from being sheared off when you open the action. Remember to practice safe shooting skills with your muzzle control when you dry fire the rifle.

 

215 Berger Hybrid three shot group Model 1885 300 Win Mag

Here's my first 215 Gr Berger load with my 300 Win Mag. At 0.6 inches this isn't too bad at 100 yards for a first load. I love Berger bullets. I shot this group a couple weeks after I took a cow elk with my 300 Win Mag Model 1885 using a 208 A-Max.

I'm thinking this is going to be my favorite bullet for this rifle.

 

1885 ring alignment

With the Talley base and rings on this Model 1885 the rings are just a little out of alignment.

 

1885 lapped talley rings

After about an hour of lapping I was able to get the rings in near perfect alignment.

I have been getting into long range shooting and have had great success with my two Model 1885s, in 270 WSM and the other in 243 WSSM. You can check out some long range action with these rifles shooting steel plates at the following links.

In 2014 Winchester brought back some of the WSM rifles in the Model 1885 and did a small run of 45 rifles chambered in 300 Win Mag. Being a guy who prefers smaller bores I have never owned a rifle chambered in anything larger than 270 WSM. To achieve better performance at really long ranges I figured that a 30 caliber was in need. With the Model 1885 being produced in both 300 WSM and 300 Win Mag in 2014 I compared the two cartridge's benefits and in the end opted for the 300 Win Mag. If I was going to get a bolt action rifle the advantages of a shorter action and the non-belted 300 WSM cartridge would probably sway me to go with a X-Bolt. However in the single shot Model 1885 the action length is the same. I can overcome the belted cartridge issues by setting my sizing die to just barely bump the shoulder so that the shell will seat up against the shoulder in the chamber giving better alignment with the bore. Also the 300 Win Mag easily gets greater velocities over the 300 WSM in hand loads. So I ordered one of the 45 rifles that would be made in 300 Win. Mag.

What draws me to the Model 1885? I've always been really found of octagon barrels. My first firearm was a octagon Marlin 39a lever action 22 rifle. I like that the Model 1885 has a extra long 28 inch barrel. Longer barrels mean greater velocity and with no action length to speak of I get a rifle with the overall length being roughly the same as a bolt action rifle with a 24 inch barrel. With 1885's there are no magazine restrictions for the overall length of the cartridge. For instance in my new 300 Win Mag I have found that the 208 A-Max shoots best out touching the lands in the barrel for a cartridge overall length (COAL) of 3.571 inches, a length well beyond the 3.34 specified as the max for this cartridge. There is also something really cool about hunting with a single shot. And how cool is it that this is John M. Browning's first firearm that he designed and sold? Really cool.

Over the years I have been mounting different scopes and using different bases and rings on my Model 1885 rifles. It has often been a challenge to find a mount that you would like to use. Here's what I have learned about this great rifle and what has worked best to mount my rifle scopes.

Scope Mounts
One of the challenges with the Model 1885 is mounting scopes. The rifle is drilled and tapped on the flat area of the barrel right about four inches in front of the receiver. It is also drilled and tapped on top of the rounded receiver. As I have learned the taper on the barrel isn't exactly the same from one rifle to the next. Basically to get the octagon barrel it is just ground out until it "looks right" is how it has been described to me. I'm sure that it is a little more sophisticated than this but in the end no two tapers are exactly the same so with a base mounted on the taper of the barrel it presents a problem in getting the rings to align.

I have tried a few different base and ring combinations in my 85s throughout the years. One system I like is a one piece blued steel base that Talley makes for Winchester. I did find that the set screws for the rear of the base to be a little too long on both of the bases I have and I had to get shorter screws to get the base locked down tight in the rear. The screws for the front of the base are a little to short to securely hold the base making it vulnerable to stripping the threads when you torque the screws. The base is designed such that it should work on most Model 1885 High Wall rifles even with the inconsistencies with the barrel tapers. With the base being made from a hefty piece of solid steel it doesn't flex much across the two mounting points and put torque on the scope however there can be a little miss alignment of the rings so it is always best to lap the rings when the base is secured and the rings attached. This is a good system for the 1885 however for my new 300 Win Mag that doesn't shoot as flat as my 270 WSM I wanted to have some MOA built into the mount so that I could have enough elevation adjustment in the scope to shoot to 1200 yards and possibly beyond.

I personally think Winchester should design the Model 1885 just slightly different so that better scope mounting options would be available. I think that the barrel should continue full bull barrel round for a couple of inches before the octagon tapering starts. I then think that the barrel should be drilled and tapped in two locations and not drilled and tapped on the receiver. Winchester could drill and tap the barrel with the same spacing as the TC Encore and many base options would immediately be available to mount a scope with 20 MOA.

So with my new 300 Win Mag rifle I set out to find the best solution to get 20 MOA out of the bases and rings. For starters I really like the 20 MOA EGW picatinny rails I have on my X-Bolt and A-Bolt rifles. I had hoped that I could find some way to get a picatinny rail to work. I studied the specs on rails and bases galore. I found that I could mount Weaver #29 and #11 bases to the rifle. I then found that I could clamp on a 1/2 inch AR riser rail across the two bases. The span between the slots in the Weaver bases is right at four inches. To get a riser rail to clamp across the bases I needed one with cross bolts that were 10 slots apart. The Lion Gears 12 slot 1/2 inch riser rail was the best option I could find, although it wasn't a 20 MOA riser. At the inexpensive price of the Lion Gears riser I ordered one just to test the system to see if it would work. Well it works perfect... almost. I found that their is a huge height difference between the two bases (39 MOA to be exact, more on how I found that out later). I found that if I clamped the rail onto the bases it would cause the aluminum rail to flex because the two bases are on different levels and if I had a scope mounted it would put a lot of torque on the scope so this idea was shelved.

I fell back to my second option to mount the scope. I used the Weaver #29 and #11 bases with High Burris Signature Zee Weaver Rings. The Signature versions of Burris' rings have plastic inserts that not only self align to keep any pinching of the rings into the scope tube, but there are also 10+ and 10- inserts that can be used to add or subtract MOA.

To start I mounted a Vortex Viper PST 6-24x50 using the Zero MOA inserts. This on a normal rifle would place the scope with Zero MOA. On my first trip to the range I found that I had 39 MOA and my scope was about 7 MOA short of getting the scope zeroed at 100 yards. I then used the 10 plus and minus inserts to lift the scope up in the front and drop it in the rear. So I placed a 10 plus insert on the bottom of the front ring and a 10 minus on the top of the front ring. I then did the opposite in the rear, a 10 plus on the top and a 10 minus on the bottom. In theory this should raise it up around 20 MOA and on the next trip to the range I found that is exactly what it did. I now have right at 20 MOA built into the elevation of the scope mount.

 

Triggers and Lock Time
I found on a forum some help with the trigger. The advise clearly worked however in my excitement I didn't take the time to find a scale to measure the difference. What I did was dry fire the rifle 10 times while applying pressure to the back of the hammer. This helped smooth out any roughness on the sear. I also learned that the trigger pull is lighter when the hammer is cocked without using the lever. So I cycle the action with the lever then lower the hammer and then cock the hammer with my thumb before firing it. I can noticeably tell the difference in the trigger after doing the dry fires and always cocking the hammer with my thumb.

Below is table showing the trigger pull weights of my High Wall rifles. One of the things that the averaged numbers don't show is that after I did the ten dry fire technique the trigger pulls were more consistent and varied less. It is interesting that on my 300 Win Mag I get a full half pound lighter trigger pull by decocking the hammer then pulling the hammer back to cock it again before I pull the trigger. Then on the 270 WSM it is right at a quarter of a pound lighter and the 243 WSSM is only slightly lighter. I have been annoyed with the trigger pull on the 243 WSSM rifle so I am going to have a Gunsmith lighten it up for me, down to around two and a half pounds.

Update March 24, 2015

I had Denny's Gun Repair in Plain City, Utah do a little trigger work on my 243 WSSM trigger. I know he replaced a spring and maybe some other adjustments. Anyhow the trigger is nice and light now, right at one and three quarter pounds. With this being my primary varmint rifle I was wanting a light trigger. I have one now. Thanks Denny!

243 WSSM (after spring replacement and work done by Denny's Gun Repair) 1.75 lbs 1.83 lbs

Obviously you can also lighten the trigger with the little set screw that is right behind the trigger. Just tighten the set screw tighter to lighten the trigger pull. My rifles have been set from the factory near the bottom already so the little I have tightened them hasn't offered a lot of adjustability but has lightened them some.

The lock time on the 1885 is the greatest drawback to the rifle. It just takes a lot of time for that hammer to fall all the way to fire the cartridge after the trigger breaks. Any slight movement of the rifle during this window of time can really hinder accuracy. The lighter and smoother you can get the trigger the better off you'll be in lessoning any movement during this window of time. 1885 rifles always get a bad rap for their trigger and lock time however I have always had great bolt action comparable accuracy in my 1885 rifles with the factory triggers.

WSM and WSSM Primer Shearing
One thing that I have found with the 1885 and my 270 WSM and 243 WSSM is that the primers extrude back into the firing pin hole upon firing the rifle. Then the falling block shears off the extruded brass when I open the action. Every so often I will get a miss fire because the built up brass in the firing pin hole prevents the firing pin from striking the primer hard enough. What I like to do to prevent this is to dry fire the rifle every so often and then open the action and blow down the barrel with an air compressor or with my mouth in the field, blowing out the small pieces of brass that get thrown into the barrel and chamber upon dry firing the rifle.

The primer shearing happens on all of my loads both factory and hand loads and I have heard that all the 1885s in WSM have the same issue. Now on my new 300 Win Mag I have had no issues at all with this happening. I'm guessing it has to do with the pressure curve of the higher pressure WSM and WSSM cartridges. I also think that the rebounding hammer allows for the extrusion to happen where it isn't a striker system like found on a bolt action rifle.  I'm not really sure but I know the pressures are not too high. Shells in my X-Bolt or A-Bolt rifles show normal primer indentions.

Butt Stock Shapes
The straight butt stock looks cool however functionally I would really prefer a traditional pistol grip style stock. Obviously a pistol grip stock is more comfortable to shoot. I find that I actually place my fingers along the lever using it as a pistol grip when I shoot. A pistol grip would be more comfortable however it is not the main reason I would like a pistol grip. The main reason is that while hunting, with the rifle slung over my shoulder the lever catches on the pack shoulder straps and my clothes causing the action to open, often dropping out the cartridge or worse, cocking the hammer while leaving the cartridge in the chamber. A pistol grip would contour right behind the lever making the lever less exposed to catching on everything. To solve this problem for the time being I wrap a velcro strap around the stock and over the lever. I can cock the hammer and take the shot. For a follow-up shot I have to spend an extra few seconds to pull the velcro so that I can open the action.

I have debated shaping a piece of wood to attach to the bottom of the stock to create a pistol grip. I may add one to my rifles in the future or purchase an aftermarket stock. For now the velcro trick is working just fine.

I have the 208 A-Max shooting sub MOA. I still want to tweak the load when I have some more time but it's shooting good enough to take it on a cow elk hunt. Once I have the 208 Gr Hornady A-Max load tweaked a little more and I will have an awesome long range rifle.

First Time Out Hunting With 300 Win Mag
I took the rifle out to hunt cow elk in January of 2015. Here's a video of a shot taken to verify the trajectory of the 208 A-Max. With no cow elk in the area I tested my new new 300 Win Mag Winchester Model 1885 High Wall shooting a 208 A-Max load on a rock at 612 yards. The shot was uphill considerably so I calculated(educated guessed, but have since learned I can calculate the shot angle with Strelok Pro using the camera in my phone) the horizontal distance of 590 yards for the shot and plugged in the data into Strelok Pro on my Galaxy S4 phone. The shot appears to hit a couple inches low so another 1/4 MOA was needed or I wasn't completely steady off my shooting sticks. :)

2014-2015 Mule Deer Photos

With the mule deer rut is in full swing I've got my FujiFilm HS50exr camera out trying to get a few photos of the mule deer in the area. Unfortunately my camera is developing a small white spot on two of the lenses that contact each other internally. This lens issue happenned to my HS20exr and now my HS50exr. I love the cameras but I guess I'll just have to think of them as disposable cameras that will last me about a year and a half.

I will continue to add photos to this post as I take them this fall and winter.
