Someone told me the 22-250 will burn up barrels because of the high velocity & I'd be better off getting a 223 - any truth here? Looking at mostly shooting coyotes & crows etc. Biggest I'd probably want to go is a 270 just thinking of hunting out west someday. I just won a 257 weatherby mag but saw the cost of the shells - gasp! So hope to sell it and get a little smaller caliber.
