Starting at Post 4 or 5, we have two different conversations going here. No problem, as long as we keep ourselves straight.
The OP says that this is range brass he picked up. He is not overloading his ammunition. The previous shooter did.
Stang46gt - Those two cases may be OK to load and shoot, but pay attention when you seat the primer. If the new primer slides right into the pocket with no resistance, the case is unsafe. The case head (including the primer pocket) expands slightly with each normal firing. But it expands a lot when overloaded, so loose primer is the bad sign to look for.
