I'm loading .50-70 rounds with 2F Goex. I put together a nice long drop tube using some copper tube and a spare piece of wood (see attached). Works great and does pack the powder in well. But loading 500+ grain slugs into that fairly small case I still have to compress quite a bit after packing. I use a thin wad on top and the compression insert for the die. The good news is 70 grains 2F can indeed scrunch down enough to permit seating of a 515 grain FN within the OAL of the cartridge.
I'm wondering, though if there's a limit to how far you should compress a load. I've looked on line and in the books and found none, though most are not compressed this far. I also found references to .50-70-500 loadings and they had to have done it to fit the bullet.
Is there a danger of a pressure-caused KB while using the die to compress the powder under the wad?
