I have the same rifle, a Cabelas/ Pedersoli .36 calibre flintlock. I was told it had a minimum charge of 20 grains 3f and a maximum charge of 40 grains 3 f. I shot a few shots at a paper plate with 40 grains but Since I intended it as a small game arm exclusively, I have settled on 20- 25 grains 3f.I keep the range very shot,I consider 50 yards a very long shot.This gun will shoot accurately further than that but that is my self imposed limit. I like that idea about the silver sight. My eyes aren't what they used to be and even with glasses I was having difficulty with that front sight of mine, now I know why.I have used the store bought Hornady balls but I cast my own using a Lyman mould. I use discarded lead flashing and dental lead.Good enough for squirrels and bunnies. Best regards,JA
