I'm gonna ask the age old question on calibers.

-I need one for coyote.
-I don't want a large caliber suitable for deer.
-I'll keep shots under 600 but likely in the 2-400 range.
-I don't want to destroy the fur badly. I'm gonna make a magic carpet out of them.

Just sometimes a livestock killing yote needs some lead poisoning.

I've got a .204 ruger which has been sweet but I feel like I can do better.

No you can't do better than a .204 that's what I use. Love it!

I have a 204 I use for this as well, can't find anything wrong with it, LOL

I gave up using my 22-250, to use the 204, doubt I'll ever go back.

But you asked for a different caliber, get a 22-250, lots of 22 calibers, 17's too that have this range. More selection of ammo in the 22's though.

.17 Remington

6.5 creedmore will flatten them WAY out there. I haven't used one yet but have buddys that can hit the 500 yrd gong off hand with theirs! I prefer a .243 with a 55grn. I can reach out and touch them with that without terrible fur damage. All Marines know how to sew, so it wont matter what you shoot one with. lol

ne 50 bmg's please!

17mach4 or 17 fireball would be a good choice. They are more efficient than the 17 remington and velocity is within 100fps or so. I've shot many coyotes, P-dogs, badgers.crows and a few other things and theyworked great. Not much fur damage at all and they shoot flat. My $.02

google the 22 TTDH, or the 22/6mm AI both more than capable at 600 yards, but they are reload only propositions. factory loads? 22/250 (a faster twist barrel) or a 243.

A 22 short will cause the least amount of damage
Don't won't big holes in that magic carpet lol!

If you can make a magic carpet, you can work some magic and remove big bullet holes .22-250

17-204 with chan nagel 30 grain hollowpoint

Let me out of your backpack and point me in the right direction. I'll just run em down

I really like .223 with a 45 grain superformance

.221 fire ball for 300 and under, very hide friendly, 22-250 there after.

I was thinking about another creedmor. I shot a hog at 400 with a .50 bmg. Went straight through him and never expanded. I expected a pink mist like you wouldn't believe. Looked like a red popcorn fart and had to trail him 60 yards.

I don't reload and thus .22-250 is my pick. I've shot several with my AR in .223 and no problems until I get beyond the 250 yard range.

Take a look at stag arms model 6 ar..223/5.56 1/2 moa guaranteed .they make it in left hand also ! It's heavy 10 lbs but 400 yards won't be a problem.Ive done more sewing with the 22-250 than my .243.Buds gun shop has them for a little over 800.00

.220 Swift

John, just like Jayme said. 22-250

Don't know why you don't like the .204. Maybe bullet choice? 35 grain Bergers are the best fur bullet by far.
