Just wondering if you all might have a AR platform caliber that would be good for Yotes, fox and Bobcat.
Yote wise not really concerned about saving hides but Fox and Cats I would want to save.
Is there one caliber that would do well for all that I could build an Upper for the AR i already have.

Do you reload?

Double tap!

6X6.8 if you reload. 22 Nosler if you don't.

I do reload yes. Not the best at it as I am still learning but have all of the equiptment to reload.

I'd probably look at building a 6x45 aka standard 223 necked up to 6mm. It's a pretty popular cartridge and a number of different places have/make prefit AR barrels chambered in 6x45.

You really need to drop caliber and bullet weight to save cat and fox hides. Like NO exit.

I've been really impressed by the 65 SGk from 223 on fox. I've got them loaded with CFE223 as strong as I dare, it would be a good deer round as far as 223 goes as well.

I havent shot any cats but all the fox hits I've made i have to search around for the exit, except one bad leg shot on a spinning fox, same for coyote.

Since your priority is fox and bobcat pelts, 17 Remington?

20 practical?

223 Remington with copper solid bullets. 45gr Barnes TSX performs excellent on everything, you'll get 100% pass throughs but small exits. I messed around briefly with 50gr TTSX but never got a good sample on predators. I bet similarly light bullets from Hammer will do as well.

Bang flop DRT on this big ol' fat coyote. 45gr TSX.


Same with these greys. Bang Flop DRT with 22cal exits.

17 Remington, 20 practical,

.223 rounds mostly just bounce off coyotes. i have read that more than once on the ole www. must be true lol

I've seen vmax bounce off angled coyote shoulder bones! I've never seen the SGK do anything other than smash through anything a coyote has.

Dirty dog, it's good to hear about the TSXs. I worked up a hot HBN lubed 53gr TSX load for the 223 and lab radars them at 3330fps. Accuracy is great also, I was hoping I liked them on fox and coyote at least as much as the 65SGK but I didnt know what to expect fur wise in the TSX .

I've been slacking big time in the coyote hunting department, I moved onto my own land now but I get so much snow, woods, outdoors and cold now just chopping wood and keeping the 800ft driveway clear I havent even taken some of my new loads hunting yet.

For that trifecta of fur, hard to beat the good ole .223. I've killed a lot of coyotes with the .223, and that's all I take with me for red fox. No cat opportunities for me. I have to travel for that, so no personal experience on them.

60 grain vmax loaded around 2800 to 2950 fps in 223/5.56. If they exit anywhere from bullet sized holes to 50 cent pieces.

What ever caliber you have on hand already.

Research and development with matching bullets & velocity to your conditions and your type of game is the fun part.

Reloading!!!

.223

I shoot a 6 MM BRX, It is the most accurate AR I have ever built. I truly believe I can shoot 20 rds in less than .500 at 100 yds. The first time I shot it was with 55 gr Blitzkings and at 25 yds I thought I missed the target the 2 nd and 3 rd shot. Then when I went to 100 yds and the first 5 shots were in the same hole. It has a 1-12 twist and likes light bullets.

What Dultimatepredator said. The 60gr Vmax will flail ground squirrels to coyotes. It is a long enough bullet that it doesn't splash or glance off on quartering shots in the .223. It'll bust bones with shoulder or pelvis shots and open up with chest hits. The only all around do it all bullet is the 130 gr Speer HP from a .30-06. No matter what angle you hit the coyote he's toast.

Used both in an AR, You will have to place your shots, don't expect to bust up sholuder bone with these two.

And bullet selection plays a lot into their effectiveness too but can be great for saving fur.
My old hunting partner shot a lot of coyotes, bobcats, and grey fox without blowing the hide of them.

I am going to throw in my vote for the 17 Remington. I've shot a lot of greys and bobcats with them and like Coyotejunki said, you've got to be a bit more precise on you shot placement and like crapshoot said, bullet choice is crucial. I personally run 20 and 25gr hollow points. This allows the bullet to get through the hide before it begins expanding to prevent splashing, but then it expands EXPLOSIVELY. It can work on coyotes but then shot placement becomes even more critical. But I have two of the hunters on our team that have even taken javelina with the 17 Rem.

Talk to DAA about some of the heavier custom/semi-custom 17 cal bullets to hammer coyotes.
I hated the performance of the Hornady hp's on coyotes when I had a 17 Remington AR upper. Probably why I sent it down the road.

Since OP asked for AR15 cartridges, I'd think 17 Remington would be a poor choice. Brass recovery in the field for one. And spotty component availability in general.

My 17 Rem was pretty tough on our small grey foxes with Hornady 25gr HP. It blew some good holes more often than not. I would not recommend it for grey foxes.

In .223 I have had excellent performance from the Sierra 40gr HV HP #1385 loaded to 3400. Hard to locate the entrance and no exit.

In 6x45 I like the Speer 70gr HP & Sierra Blitz 80 gr SP. They usually exit but the exits are small. I also use these loads for deer.

In .300 Ham'r I like the Sierra 135 gr HP, Speer 130 HP and Hornady 135 FTX.
This is a 135 FTX exit.



For a do it all rifle / load I use the .300 Ham'r. All of the bullets I listed are loads I use for deer and they have performed well on Yotes as well.

These 2 were taken the same morning with the Sierra 135 out of the Ham'r at 2400 fps.

Out all of 3 that I own..

204 Ruger
223 Rem
17 Rem

I’d have to pick the fast 20. I’ve shot everything from coons to deer with that rifle, and never had a problem. Bullet selection and placement has a lot to do with it too though.

I’ve killed countless cats, foxes, coyotes with no fur damage. But I’ve opened up a few too by accident. It just happens.

I’ve got 3 other rifles that if I’m just targeting coyotes I’ll take my pick for the day. But if I feel like we’ve got a good chance at a cat or fox country, I’ve always got that 204 with me just for it.

I sure like those 204 Rugers. Shot a BUNCH of Praire Dogs and a few coyotes, on the coyotes I did not experience major fur damage, primarily use 32gr. Vmax about 3940fps, if I was going to target coyotes, I would move up to 39gr SBK or 40gr Vmax ( if 40s will stabalize ) I have 2 with 1:12 and they both shoot the 39gr very good, have not tried the 40s. Recently got a White Oak complete upper in 204R, 1:10 so I am pretty sure it will handle the 40 and maybe even 45s if needed, only been able to shoot paper with the AR so far, but holy smokes does it shoot. 204 with a suppressor is less noise and recoil as a 22 LR, can see your hits and the flips..makes em great green chilli!
