It seems like most western coyote hunters prefer the .22-250 for it's longer reach and higher velocity in the wide open spaces they hunt. The .223 Rem. makes more sense to me for PA. hunting. It's easily a good 300 yard cartridge/rifle combination. I just recently ordered a Savage 12FV-S in .223. I already reload for the .223 and plan to use 50gr. Nosler Ballistic Tip bullets for coyotes. It should work well on groundhogs also.
