Nothing wrong with Core-Lock's for sure, but, like last year, my doe was shot at 347 yards in southern Kansas. I was using m 270 WSM though. Year before, shot my 11 point 200lb buck at 30 yards using my 7-08 Savage with the Remingtons, but a lot of my shots are usually long around here, Kansas and Oklahoma wheat fields........so I like the flattest shooting ammo I can find........
