I'm resizing .45 ACP's tonight and just happened to notice what looked like a large flash hole in a "once fired" Winchester case. It easily accepted a 1/8" drill bit. A new unfired Starline case passed a 5/64" but not 3/32."
So I began paying closer attention. 8 Winchester cases all passed a 1/8" bit. 16 Federal and 5 Speer cases passed a 3/32 bit.
A "top brass" case only passed a 1/16" bit!!!
It has been my understanding during the years I've loaded rifle that a uniform flash hole in a rifle case should be 5/64."
I'm assuming the 1/8" holes are too large and these are certainly not "once fired." Since I've reloaded several hundred rounds up to this point before I noticed this apparent discrepancy, is there any danger to having too large a flash hole in the primer pocket?
