Re: 175 MK\'s...1-10" or 1-12"?
Marine sniping rifles in .308 are twisted 1-12. Marines shot them out to 1000 yards with the 175grSMK.
S1, could you elaborate on the weather conditions where 1-12 will not work, and exactly what effect these weather conditions have on the bullet/accuracy. I do not ask out of disbelief, but it surprises me that the military would use 1-12 if 1-10 would have advantages in variable weather conditions.
