I shoot all roundballs. I forgot the name of the forest, a large one north of philly that has the end of january extension. I was up there 5 years ago and joined in a drive with some guys hunting there. One of them had a custom flintlock, but with 1:28 for sabots. It does sound slick.
I Probably shoot 8-10 roundballs to a centerfire cartridge at the range. I shoot muzzleloader competitions locally, Almost all are woodswalk. I know the 54 trajectory pretty well. I don't mind a real nice huge buck, but my priority is an ethical shot. Im more than glad to pass up shooting a deer, just happy to see a nice one, even happier If it didn't notice me. I "shoot" every deer I see pretty much. Mount the gun, keep it steady to 10-15 seconds. Then I can say I could of shot em. Also, doing that really tones down the buck jitters. That and shooting deer shilouettes.
