yeah for sure if you used pistol powder but I thought he was saying you could double charge with 50bmg powder, and I thought he had maybe knew something I didn’t lol.. I think those slap rounds got tumbled to be polished up, remember the yellow 50bmg ap rounds that were imported years ago from the Dominican?? Nobody shoots that **** cause it’s was stored bad and tumbled and stored bad and tumbled and maybe tumbled again, the powder is so broken up it over pressurized because of it, the only safe way to shoot them is unload dump powder and replace with néw
