My hunting gun for years was a 13/16 50 cal made by Getz. A guy at the range had to have it so...................................
Anyways..... My hunting load was 120gr 3F and 2 .490 patched roundballs, one on top of another. They hit side by side at 50 yards and I NEVER had a Whitetail run, just collapse...
It had a white lightening touch hole liner in it.
Never had issue.
Was my favorite hunting/killing machine
Just my .02
