[QUOTE="Lefty7mmstw, post: 830489, member: 48043"] I've also got a 10" twist 7stw. For a while that was the norm for twits who thought they could get a bit more speed out of this cal.. Use a 9 " twist so you can go to 175-180 grain pills and keep the bbl. length up if you want the last few fps. I've shot the 160 abond in a few rifles and the 140 has turned in better groups in every one so far. The bc isn't very different considering the weight difference and the 140 will outrun the 160 by 200 fps in most bbls. [/QUOTE]
