I'm working with some 140gr bergers out of my 270 WSM and they shot well. I'm running them @ 3385 fps.
Took it out last weekend and punched a coyote and I don't think they opened, one shot center punched the shoulder rolling it then got up and got into a draw and it popped out @ a little over 500yd and center punched him again and that did him.
I was not expecting them to be a good for varmits but I need the practice for this fall.
They sure are a sexy projectile, I'll shoot some deer with the Berger and the AccuBond this fall, I really like both.
