I have a good number of molds and loads for .45/70, but one of my favorite deer killers is my 340 grain Lee mold. That mold casts slightly undersize at .457, so to "fix" it, I cast first with a fairly soft alloy , at about 8 to 10BHN, I then paper patch it up to the crimp groove with 2 wraps of tracing paper. After it's dry, I trim the tails, apply just a smidge of case lube to paper and size to .460. I use enough RL7 to push it about 1950 fps. Expansion is pretty notable, even on thin skinned white tail deer. I use these in 2 Marlin rifles and have used them in a Browning B78..
