Since you like the 6.5 already, I would stay with that. I have a few that I prefer 264 Mag. Elk, 6.5 X 55 Deer-Pronghorn, 260 Deer, 6.5 X 284 Matches and there are more to select from and array of projectiles as well. I prefer the 160 Matrix for Elk, and the 140 Partitions for Deer-Pronghorn.If you were operating on a $2000 budget (rifle/scope), and you were primarily hunting deer and the occasional elk, what would you buy? I'm also looking to punch some paper out to 600 yards. I'm not married to any brands or calibers in particular. My son has a 6.5 Creedmoor, so it wouldn't hurt my feelings if I ended up getting another one, but I would be willing to look at other calibers, although I am a recoil sissy and his is a lot of fun to shoot. Anyway, thanks in advance for your willingness to share.
