I didn't do any LONG range shooting, but the choked Bauska barrel I played with, used 480gr. .50 cal bullets and 80gr. GOEX 2F. I lubed with Crisco which actually worked well, until I stumbled over 60/40 Beeswax/Vaseline. That lube was super and very accurate, at the same time as keeping the fouling soft with the grooved lubed bullet. I also tried it in a .45 GM barrel, slow twist with 220gr. R.E.A.L. bullets. That lube as well as Lyman's BPGold were quite accurate. i was able to shoot 20 shots, without wiping, then went back to shooting patched round balls, without having to wipe the bore first. The first shot with a patched round ball, effectively cleaned the bore for subsequent shooting.
