I addressed this earlier... some handloaders discussed what they described a phenomenon of AA#7 flattening primers even in sub-max loads. Normally, I would have stopped with a flattened or cratered primer... yes.
Anyone else heard of this?
Thanks for taking it as it was intended. So what flattens primers? Pressure, right? How could the pressure from AA #7 flatten the primer but still remain at a safer level than another powder that did the same thing? It just sounds like myth to me, luckily a myth that isn't too widespread.
