I have a .243 and it loves the XP
So does my 30-06, my brothers 30-06, my father in laws 30-06, my brothers 300 Win Mag.....
Excellent bullet. Every animal went bang, flop with it.....well, technically one actually went "flop, bang" (lol, read below.)
My dad used my .243 in WY for antelope. I was watching from 1/2 a mile away as he was stalking a nice goat. I knew my dad was close, but lost sight of him on the stalk. Not being able to see him i started watching the goat. All of a sudden it looked like someone cut the strings of Pinocchio. A second later I even heard the shot. It was one of the coolest things I've ever seen watching an animal drop before you can hear the shot. Flop, bang!
Last weekend my FIL and I were shooting long range, but before he hadn't shot his 06 since WY three yrs ago (rifles aren't allowed in our state) and he wanted to verify his zero. No my FIL isn't a huge hunter, he does it cuz I love it and just wants to have something in common with his SIL and for us to spend time together. He certainly hunts, but he's not gonna do it without me. And he's an average shot.
So on Sunday, he goes out, his gun is 4 inches high and an inch left. We make the needed adjustments. Bang, 3 shots in a nice little clover leaf, right at 2.5 inches high, dead center, with 150 Gr Winchester XP.
Great bullet, accurate in every rifle I've used it in and I love its performance.
