Trouble loading sabot conicals.
I just got my first in line (traditions thunderbolt .50 cal). When I tried to load a sabot with conical (hornaday .50 cal 45-300 GR SST'ML) it stuck in the muzzle. I had to use pliars to remove it. I tried lubing the sabot and this time (with considerable force) I got it about 8" down the muzzle. I had to remove the breech plug and use a brass rod and hammer to drive it out. I am used to shooting patched round balls in my traditionsal muzzleloader. What am I doing wrong?
