Man I have just read through all 26 pages of this thread since about 7 this morn. I'm trying to get an idea of a starting point for my build, but the one thing that was missing from just about all the posts was twist rate. Each member gave specific information. Bullet weight, powder of choice, grains, brass, primer type, brand of bullet, speeds, but the one thing I was looking for was twist rate. I have been a Browning abolt 7mm guy all my life, but with the recent purchases of .308's that my sons have, I decided to get one. Rem 700 action with #4 shilen contour at 18" threaded for brake of suppressor. All 3 of the .308's are Rem 700's in 1:10 twist. It just would have been nice to see 1:10, 1:11.25, 1:12 depending on your "recipe", if that will make a difference. I know some heavier loads will shoot better in 1:10 vs 1:12, but what do I know. I'm just a NEWB who read 26 pages worth of information that I 'm just learning about.
