Breech seating grease lubed boolits over blackpowder
Have read enough info on the "how" of this .. really interested in what improvement in accuracy was achieved? .. what calibres responded? (38/55 and 45/70 would be what I try)
And one question ....the PP boys use a wrapped bore size boolit and it slugs up and engraves the rifling when its shot .......can we get that to happen with an undersized grease lube boolit? --(say a .454 slug in a .457 groove barrel? would it fill out like the pp slug or no?)
