I designed the feeding systems for the 22ccm Dan screwed me after that but it is a good cartridge for yotes .....personally I use my M4 for wolves until the wolf was "reintroduced" I never killed anything I wouldn't eat.
Tikka m55 in 243 win for now. Building me up a custom long range 243 for my night force. Plus I use my 308 on them to.no coyote safe for 1200 yards at least. Working on getting a 338 lap and yes I'll pop yotes with it.gun
Got a Rem. 700 in .257 Roberts with a 85 gr. Nos. bt that shoots really well.
Was calling back in December with a couple friends in a close quarters set up and had a pair of coyotes blow right in on top of us with out anyone being able to get a shot off and where gone just that quick. Since then we ordered a new barrel for the 12ga. 870 Express with a full turkey choke and hope to try it out soon..
I love the AR platform for yotes. Had a custom 22-250 40x that shot lights out, but way to heavy and nearly impossible when multiple dogs come in. I went with a 204 and its great at medium range, but worthless past 500. In addition, slug around a 1187 with buck shot for certain stands.
