jst wondering what bullet has worked well for some in the past. i've been shooting sierra gamekings 55bthp and have had mixed results. they're great out of my 22-250, but shot at slower speeds w/ .223 i've had trouble w/ some varmints not dropping in their tracks; even with good solid hits. i'm definatly changing over to a ballistc tip, but would like to hear some other peoples experience.
