RE: Winchester XP3
Is that a boattail design? Ive never had any luck w/ BTs . My Savage and remy seem to group best w/ plain old flat base bullets like corlocs and hornady interlock.. If your after deer sized critters, anything that pokes a decent hole though the vitals will do. With the price of ammo these days theres not much argument for a premium or fancy bullet for deer IMHO. Good luck.
