I like that idea, but I think the alcohol would flow out through the flash hole unless I plug it up. Maybe I could seat a primer in there for that? Would that be safe? Could I deprime it afterwards without the primer blowing up?PhillipM said:To check the volume without measuring tools fill it full of alcohol and pour it into a commercial case. Alcohol doesn't have the surface tension water does and will lay flat.
Well I don't have any spent primers 'cause I always trash 'em right after I pop 'em out. Guess I should have hung onto a few. Oh well.PhillipM said:I'd put a spent primer in for the test. If all you have is a live primer I'd fire it afterwards rather than risk depriming a live primer. I guess you could also jam a toothpick in the flash hole as long as the same amount protrudes into the case. Both need to be sized or both fired from the same chamber.
