I'm looking at loading a handful of blanks for a 38 revolver. I would prefer smokeless powder. I've read where some drill the primer pocket flash hole bigger to get a faster burn.
Does anyone have any experience with this that could share some input?
Thanks for any input

Drill out the flash hole, insert a small pistol primer and Voila - a pretty loud blank with no powder. Enlarging the flash hole helps to keep the primer from backing out and binding up your revolver.

How about a small rifle primer instead?
