Re: PB from a flinter ???
No issues at all with BP. I think their nemesis is penetration with high velocity. I hit a quartering doe at about 20 feet, over 1600fps. There was no exit so I wanted to recover the bullet. I couldn't find it even after going through everything with my fingers. I skinned and butchered the deer where it laid and came back with my metal detector. Went over the hide, carcass, and guts. No bullet but there were small lead shavings throughout everything, it disintegrated. Based on that experience I used the platinum PB for the elk. It did well enough but didn't exit on a perfect broadside hit at about 60yds, found under the far hide. With your deerslayer and bp wouldn't expect velocity over 1500 and on deer it should do well.
