Then this leaves the RH v. LH twist direction... and how many lands. I like the idea of narrow ones, the barrel mostly bore and am leaning towards 4 lands, of size/width about 30-35% of groove width.cheers,Douglas
Yes there is a 2 groove taper lapped 22 cal barrel used on the USFTs. Made by Benchmark?
I was going to suggest 6 with narrow lands.... *LOL*.... only because I know that works from the .22, .30, and .35 cal mandrels we had made.... Didn't Tim @ Mac1 have some barrels made that were only 2 lands?....Bob
