So, let me get this straight.
They got a used drum, probably traded in because the purchaser fucked it up and didn't want Mike to find out.
Then without even inspecting it they tested it against their drum, that they dialed in over the last year.
It also looked like they used ammo that is listed as not usable without the new spring.
My 2 drums work perfect, 30 second fitting job on one of them.
Mike has them scared.
