Howdy all. I'm thinking about loading some .38-40's for my '73 Winchester and am planning to use smokeless powder this time. The rifle is in excellent condition and was built in 1888. I was considering a light load using 7.5 gr. of Unique powder with a 176 gr. cast boolit. The boolits were cast in a Lyman mould no. 401043. In order to make the maximum OAL of the cartridge, I have to seat the boolit on the ogive rather than in the crimping groove. That'd be OK for black powder since the case would be full enough to make a slightly compressed load which would prevent the boolits in the cartridges in the tube magazine from moving back into the case under recoil. But with a tiny amount of smokeless powder, there's a lot of empty space in there and nothing to support the base of the boolit. But maybe with such a light load it wouldn't matter? Is this particular boolit going to have any movement problems with this load of smokeless powder? Thanks for any help or advice!
