The season opens for me tomorrow 1st Sat. in Nov, as it has since I started muzzleloading hunting 5 years ago. 5 shots over the years. I don't know from fragmentation, disintegration, pass through, performance balistics, run off after shot. I guess some of the spent bullets were in some of the 5 gut piles. I did recover 1 bullet perfectly mushroomed in the far shoulder. I undrestand bad groups. I wouldn't have that either! I never cared about bullet mumbo jumbo. Shot placement. If I don't place the bullet behind the shoulder, then I don't expect the bullet to save my tail. 295 Powerbelts have been perfect for me. No deer has gone 5 yards!
