[QUOTE="BallisticsGuy, post: 1491005, member: 96226"] For it to not group farther out means either it's the shooter (possibly not using parallax setting or just not being very consistent) or precession is grabbing you by the short and curlies or you're actually doing just fine except for windage and you're counting windage dispersion. Given a 60 grain bullet in a 7 twist, I'm calling it as likely precession. You're spinning the living hell out of that bullet and possibly a little cattywompous in alignment. What I would try are Barnes 50gn Varmint Grenade bullets (not the 36gn'ers). They're about as long as a 70gn bullet so your fast twist won't be such a handicap. They'll punch through the side of a yote and grenade in the pumping room. No good for quartering shots as they don't penetrate real deeply. Really want broadside. By "don't penetrate deeply" I mean I once shot a jack rabbit at 15 yards with one and it didn't exit. It did gut the thing completely though. Weird from a broadside shot. [/QUOTE]
