Minimum powder charge... please help!
I'm going shooting tomorrow with my brother. He has a .54 cal Lyman Deerstalker rifle. According to the user's manual, the MAXIMUM powder charge is 90 grains of FFF powder (or Pyrodex) but I'd like to know what the MINIMUM is that we can use for a day of target shooting. There's no sense in wasting powder and blowing out our shoulders if we don't have to. I've been searching the internet for an answer, but haven't found one yet. What do you think would be OK for shooting at a paper plate target at 25-50 yards? Thanks!
