I have a .50, and it has to be shot to be believed. And with the .50, it’s more than just the bullet going down range, it’s the pressure wave that hits the shooter. I actually put a suppressor on mine in order to be a better neighbor to people I am sharing the range with. It doesn’t make it hearing safe, but brings it down to a tolerable level more akin to a magnum rifle.
However, I do have some concerns. Was this the guy’s first time shooting his .50? It doesn’t do him or anyone else any good to be destroying his plates or trees. In fact, it’s a bit reclouse and dangerous to be firing rounds that are not 100% contained. So, he had bullets going through his steel targets, his berm, and at least one tree. So, where did the bullet stop?
