243 WSSM Model 1885 Coyote Double

Two coyotes, Model 1885, 243 WSSM, Homemade Electronic Coyote Caller

Every summer since I was little our family has gone camping for several days in the Cache National Forest of Northern Utah. I have many a great memory of these camping trips. Now that I have my own family we have continued the tradition with our own children and my parents who are now Grandpa and Grandma.

The area that we go camping in always had a lot of coyotes but a couple of years back some pretty extensive reduction of their numbers happened. I believe this came by the hands and helicopters of government employees in which I was happy to see because the deer numbers were getting pretty low at the time. Since then I have seen little sign and usually only when there is a sheep herd within a couple miles. I still always throw in a rifle and caller just in case I happen to find some coyotes but knowing most likely there may not be any in the area.

The first three days of camping this year I was unable to find any coyote tracks or scat within the general area we were camped. On Sunday night about a mile away across the canyon a male coyote surprised me and started doing series after series of challenge yelps, howls and barks for well over an hour straight. It appeared that he was very upset with either another coyote or my wife's little yapper dog that we had with us. Whatever the case, it was Sunday and I have a personal belief that I should not snuff the life out of furry woodland creatures on Sunday. Oh, how I was ever so tempted to sneak past my wife, go across the canyon and silence that song dog... That night I strategized over and over how I was going to out smart him in the morning.

Early the next morning I grabbed my 243 WSSM Winchester Model 1885 single shot rifle, some optics and my homemade DIY electronic predator caller and snuck out of camp before anyone else was up. I slipped into a sagebrush draw that looked across the main canyon directly across from where I had heard the coyote the night before. I figured that at best I could get the coyote to come out of the pines and quaking aspens on the other side of the canyon and look across from some cliffs that formed a gorge like canyon. This would offer a 300 yard shot and if I was lucky I would be able to get him to cross the gorge and offer a closer shot on my side of the canyon, that is, if I could see him in the sagebrush before he winded me.

Once in place I set my homemade DIY electronic predator caller to repeat a series of challenge barks in much the same manner the coyote had been doing the night before. I figured this coyote was obviously upset with someone in his turf and a little challenge might be just the trick to tick him off and let down his guard. I started the caller up and it wasn't 30 seconds and to my right on the same side of the canyon that I was on two coyotes were coming in full throttle through the sagebrush. As they crossed through a small draw and where out of sight I repositioned myself and setup on my shooting stix. They both stopped at about 100 yards across the draw I was in and I could only see the one so I dropped the hammer on him and down he went.

The sound of the exploding bullet on the coyote and the electronic caller still playing, I think confused the second coyote and she started running parallel to me at about a 100 yards crossing down into the draw I was in. Just before she made it to the thick sage in the bottom of the draw she stopped to look back up at the challenge barking coming from my caller. I was ready and dropped the hammer on her for a double, with a single shot rifle, in less than two minutes of calling .

At first I figured that the coyotes had to be young uneducated coyotes to come in so fast however they were an adult male and female pair. This makes since because the challenge barks I was making probably would scare off the younger coyotes.

I was using Winchester factory loaded 243 WSSM 55g Ballistic Tip bullets that chronograph at 4240 fps from this rifle. The coyotes where 95 and 97 yards away according to my Bushnell Elite 1500 range finder.

243 WSSM Rock Chuck Hunting with Video in 2010

243 WSSM Model 1885 Rock Chuck Hunting
View of my 243 WSSM Model 1885 from my lap while rock chuck hunting.

Dallen and I took a hike to hunt rock chucks this past week. We went into a area that usually has abundant numbers of chucks however this year we only found a handful of chucks.  We had given the area a break from hunting the previous year so maybe some else had been in the area the past two years. Who knows. We did find a few rock chucks and were able to have some fun.

Dallen was packing his Browning A-Bolt Stainless Stalker in 223 Rem. and was shooting a 50g V-Max handload clocking right at 3,000 fps. I was packing my Winchester Model 1885 in 243 WSSM shooting factory 55g Ballistic Tips, clocking in at 4240 fps, with this 28" long barreled rifle.

Both of us are shooting from a sitting position. I am using a set of Stoney Point Shooting Stix and Dallen has a large Browning Bi-Pod on his rifle. He prefers Shooting Stix but we think his set got left on the mountain when we shot our cow elk this past winter.

I let Dallen take the first crack, at the first chuck. It was a small chuck, at 246 yards. It takes him three shots to connect on this rock chuck. His first two shots are near misses. I have to give him credit as he is only using a 3-9x Bushnell Elite 3200 rifle scope and shooting with a bi-pod from a sitting position. After his first two shots I decide to take a "warm up" shot myself and just skim the top of it's back for a miss... and I have no excuse, I just missed. You will notice a considerable difference in the speed of the bullet and the impact on the rock on the third shot in this video. When I have my rifle down to reload Dallen center punches the chuck on his third shot.


This rock chuck is at 244 yards and I send him a flying with a center punch from my 243 WSSM Model 1885, using a 55g Ballistic Tip, having a 4240 fps muzzle velocity.

We didn't get to shoot very much this trip out but we had a lot of fun nonetheless. The trip also provided some much needed exercise. I have put a few pounds on this past winter. I need to get in a little better shape and take several more trips like this before summer is over. Dallen and I had a great time. I really enjoy the talks we have when we are out hunting together. He's growing up on me.

DIY Homemade Electronic Coyote Predator Caller

Do-It-Yourself Homemade Electronic Coyote Predator Caller
Do-It-Yourself Homemade Electronic Coyote/Predator Caller

Being the Do-It-Yourself guy I am, I thought a homemade coyote caller would be a lot cheaper than a commercial electronic call and a fun project for me to tinker around with.

I started out using an old Browning flashlight housing. I got an inexpensive mp3 player and the Speco SPC-5P speaker from eBay and a old double male audio cable I had kicking around the house. The rest of the parts needed I ordered from Radio Shack.

The battery pack holds eight batteries so to achieve 9 volts (6 times 1.5v AA batteries equals 9v) I placed a piece of copper tubing across one of the two AA battery slots. Having this larger pack of batteries lasts a lot longer than just a single 9v battery.

I then cut the bottom of the mini amplifier off so that it would fit inside the flashlight case and wired it as shown in the diagram.

Homemade Electronic Coyote Call Wiring Diagram Using audio editing software I changed the meta tags of all my predator MP3 sounds. I changed the "artist" tag to different animal sounds. In this way I could browse by artist and bring up all the rabbit or coyote sounds etc. I set the MP3 player to repeat so I can pause and play the same sound over and over.

Another thing I like to do with my MP3 files is make 20-30 minute calling scenario MP3 files. I do this by bringing various sounds into my audio editing software. For instance I will have two minutes of silence at the beginning, then I will have a series of mouse squeaks and then a minute or so pause. Then some louder rabbit squalls and then a couple of series of the rabbit squalls over a ten minute window. Towards the end I will often throw in a coyote challenge bark/howl and then a distress ki-yi bark. You can also mix in bird sounds all along the way like a crow or a magpie. I think you get the idea. You can have fun and make all sorts of various predator calling sequences.

A pair of coyotes taken with my homemade electronic caller. You can read more about this hunt in my 243 WSSM Model 1885 Coyote Double journal entry.

When I have these long pre-made audio sequences I can set my call out in front of me however far I want. I now have two minutes to get back into position before the mouse squeaking starts. Then I sit back and enjoy the show.

Basic parts list that I used:

  • MP3 Player
  • Housing, from a flashlight case or gym bag etc.
  • Speco SPC-5P Speaker
  • 8 "AA" Battery Holder (Radio Shack, Catalog #270-407)
  • Red LED with Holder (Radio Shack, Catalog #276-084), Optional but nice to know when it is on.
  • Fully Insulated 9V Battery Snap Connectors (Radio Shack, Catalog #270-325)
  • SPST 3-Amp "Soft-Feel" Push On-Push Off Switch (Radio Shack, Catalog #275-1565)
  • 3.5mm male to male audio extension cable
