I'm thinking of getting a .223 (unless I can convince my wife to let me splurge for a TactTwenty) for coyotes mainly and various sundry other varmints (see other post for plans). However, some I've talked to here in UT keep telling me the .223 doesn't have the poop for the longish shots (>300yds) that they claim are the norm here. I'd probably load a 50gr. bullet of some flavor. True, not true? Most here suggest either a 22-250, Swift, or 243. I like the cheapness of feeding the .223, which I plan on shooting LOTS!
