Hi there Lonewulf,

A paper patched bullet would be about the same length as the grease grooved bullet unless the ogive is lengthened and the bearing length is reduced. I based the bullet design on original Holland & Holland 12-bore and 8-bore designs but a longer bullet could certainly be made--especially a Forsyth shell or hollow pointed design. That twist rate certainly leaves a lot of options, but I was trying to make what I think is the closest thing to the design that was originally used.

Regards,

Jim
