Interesting report there Semi. The only time I have used a reduced load was in my .58 cal. N-SSA Zoli-Zouave. I am shooting about 41 grs. of Goex FFg.
I have a Hawkens Carbine with a twist rate of 1 in 66". I have not shot it that much I am ashamed to report, but now I will try lowering my loads. I am currently shooting about 95 grs. of Goex FFg with a 490 gr. ball and a .018 patch.
I really appreciate you taxing my brains and skills on these tests. It also gives me something new to work on my range visits.
