Gain twist.

[bruce moulds]

kurt ,
why do we do anything?
you won't be happy 'till you scratch the itch. just do it.
I went for the 2:1 ratio because the old british match rifles used this.
also I wanted to drive bullets hard for long range, and thought it would give them a gentler start with the slower twist at the breech end.
if you can get a 40 cal, why not try a 40/90 b.n using 45/2.6 brass?
keep safe,
bruce.
