So a slow moving 45-70 bullet blew up into dust on a shoulder ??
Yes. When the Leverevolution ammo first came out, bullets exploding was a fairly common problem. A lot of guys hunt with 45-70 here for primitive weapon season. There were a lot of pissed off hunters and the round got a bad reputation. Lot of thick timber around here and shots are often really close. The problem was with the first year of the introduction. I know of a lot of boxes of the LE ammo that got sent back to Hornady. Poor quality control or bad design, but Hornady fixed the issue pretty quick. Have not heard of the problem now in several years.
