I want to get a new rifle for coyote hunting in PA, going with friends that use dogs to hunt. I'm looking at these calibers 22-250, 223 and 223wssm w/BOSS. Looking for advice from people that have used these calibers the pros/cons. Not familar with 223wssm do they burn up the barrels T or F Browning says they don't, although they are dropping the wssm in 2008. I just want to know if it is a good caliber (that just didn't catch on and got a bad rap for no reason)and how it compares the the 22-250 in ballistic, flat shooting etc.. Also, rifles like Savage Predator, Brownings, CZ's, Tikka etc. I'm not brand loyal, although for me its hard to beat Brownings 60 degree throw bolt for scoped rifles.
