[QUOTE="Lobber, post: 1444115, member: 95131"] Thanks Rhett, That's good to know. I'm not too worried about an 8-twist stabilizing the 140-143gr class of bullets, but I'm uncertain if an 8-twist adequately stabilize the 150 gr class of bullets as they seem to add quite a bit of length over the 140-143 grainers, if I try to take that plunge... I'm wondering if a 7-twist may be adequate for all the above, but I have no idea how that tighter twist might impact barrel life... Perhaps a 7.5-twist may just be the sweet spot for any of the heavier bullets, but the barrel that I had planned on using is not actually available in a 7.5-twist, as far as I can tell. [/QUOTE]
