i firmly seat my bullet,sabot. for some reason my first sidelock m/l rifle the conical would move off the powder 2"-3"
. i would constantly check to make sure it was seated fully.
the one i am using now i seat it with the ramrod, give it 8-10 extra taps with the rod. after pouring the measured powder down i would hold it muzzle up and rap the side of the breech area with my hand,with the nipple side slightly downward to get a little powder into the bolster/ nipple area. put a cap on the nipple and put the hammer on half-cock. unless i was ready to fire at the range.
no more trouble with the inline since i started using sabots
.
