[QUOTE="tim_w, post: 1444293, member: 11132"] Its really simple. If you care about the bullet max BC and stability in ALL conditions and elevations then use the twist the bullet manf recommends. If you not then you have choices to make. Also there is no way one inch in length of twist angle is going to have a real noticeable effect on barrel life. Long shooting strings and pushing max pressure with double based powders has the most effect after bore surface area to powder weight used. If you are that worried about the initial bullet engraving angles effects peak chamber pressure and heat etc then get a barrel with a 1 inch gain twist.i.e. 1:8 - 1:7 twist. Bartlien does this frequently. [/QUOTE]
