Re: My "New" 20 Gauge Rifle Rolling Block

The reason I tested the undersized patched balls, was for a cleaner shooting load that would not powder foul the rifling. Without some method of introducing lubricant with BP loads, fouling will build up.
The patch took care of this. A lubricated wad would also have worked.




@ Daryl_S: My loads have lube "cookie" inside. I put in 70-75 gr FFG followed by nitro card. Then a 3/8" fiber wad followed by a small dollop of Bore Butter. Then tap ball into case. The Bore Butter seems to keep fouling soft.

@Longknife: Not sure of twist. Told smith to put slow round ball twist and he said he would figure out best. Probably 1:66 or something of that nature.
