Drilled-out primer holes?

[Buck13]

On my silly no-powder shotshell thread
http://www.thehighroad.org/showthread.php?t=801599
it was recommended to drill out the primer holes.

I have enough .38 brass (and .44 brass, if I decide to "magnumize" this idea) that I can afford to waste a couple dozen cases like this. I would dip or spray the heads in enamel to mark them, but still wonder if this would be a hazard if they accidentally got back into a batch of normal rounds. Does this create a dangerous condition due to squibs?

Won't get a squib, assuming a proper powder charge, but you may get backed out primers.

You need to drill out for blanks and no powder loads to keep primers from backing out. Use a .140 drill.

I have a couple hundred 45 Colt cases that have the large primer holes. Shoot regular loads and haven't had any problems. As usual, start low and work up.

Starline Brass uses .140 flash holes for their blank brass. I remember having to open up flash holes on .38spl,44spl brass when I was using X-Ring rubber training bullets for short range practice.

Running the standard factory flash holes caused the primers to back out and bound up the wheeley-gun.

Do not underestimate the power of a primer.Those same blank cases I made,powered by a standard pistol primer and a foam ear plug for a projo,almost went thru 1/2" sheet rock at close(under 10') range.

I stand corrected. Second time this year!
