As a side note - friend Keith's .75 has a 56" to 60" twist I think (Getz ML) barrel and it shoots well with from 100gr. to 200gr. of 2F with a heavily patched .735" WW alloy ball. Until he reduced his charge to below 140gr. 2F, Keith couldn't keep a WW ball inside a moose. Boom - WHAOK - down - or stagger & down. What a gun! Quite similar results with my little 14 bore.
