I've figured out what the Sig 556 likes best but my new LMT is still going through the testing phase.... So far I've tried the 55, 62, 75's and some Black Hills 77 gr. HPBT Match but still have not found the "magic" bullet that will perform consistently/accurately from it.
Wouldn't it stand to reason that a barrel with a 1:7 twist would prefer a heavier bullet? Should the 77 gr. have performed far better then the 55?
I've seen some 80 gr. but they call for match chambers or something to that effect. How high weight wise can I go with commercial/military ammo?
I have three different barrels a 10.5", 14" and 18" for this LMT and so far none of them like what I have fed it......
Maybe I'll get lucky with the 69 gr. bullets? Would it be uncommon for it to prefer a 69 grain vs. a heavier bullet considering the 1 in 7 twist?
Thanks.......
