That guy has some really good flintlock historical hunting videos. Never seen this video though. Thanks for posting. That CVA mountain pistol he's using is like the one I always take to the deer woods. Excellent pistols.
I went back and tracked down the ITX round balls the shooter mentioned. Good to know there is a pretty decent substitute for lead if the antis tighten the screws on us. https://tomboboutdoors.com/itx-roundballs/
