device to fire just primers

BayouCritter

I am training a lab puppy and want to get her used to gunfire when I throw the dummy. I was told of a device to allow me to drop primers in a single shot gun fire then easily remove and replace another after firing. Anyone know the name of this or where I can get one for a 410?I thought of using a starter pistol, but would rather get her used to seeing a long gun raised. She's a sharpy for a 4 month old.

you might get someone to just load primers in some empty cases

I remember reading about just firing primers in an empty shell. It had something to do with the primer backing out and locking up the action. Seems the recoil of a normal round would provide enough recoil to reseat primers, but if there was no recoil you would get a jamed action (sometimes). Any experts out there know about this situation?

Sounds like the shell fired had a worn out primer pocket. I have tested guns and ammo by firing empty shells w/primer and have never had a primer unseat. Primers do not unseat and reseat when fired.

I'm afraid I'll have to disagree. The force of the primer explosion acts against the primer pocket and the primer will back out of the case to the extent of the headspace of the case in the chamber. The effect in single shots and semi autos is academic but in revolvers where sliding clearance is necessary for the cylinder to revolve,it will take up all the running clearance and often bind up the cylinder.The people that make rubber, primer fired bullets tell you to drill flash holes well oversize to avoid the problem and to paint the cases to identify them. It works.

v35 is right on the money; if you don't believe him, try it yourself.

I bought some used brass recently and one case has a live primer. What would you men suggest I do?

To the first question, years ago I took asingle action colt and dressed up like a sheriff for halloween at my church. I took, a bunch of brass and loaded just primers. Had no problem whatsoever. I kind of like the idea of getting the mutt used to gunfire that way. I think thats' pretty smart. Question 2 I have had to deprime with the depriming tool and its' never set one off yet, but all you have to do to be safe is spray some oil inside the primer from the open end of the cartrige and this destroys any powder or gunpowder like explosive completely. You'll have to perfectly cleanthe brass of oil afterward or it will ruin your next reload too.

bwa, depends on the caliber. I've fired off a bunch of primed brass and sometimes in a revolver the primers will back out & bind the cylinder. Nothing terminal, though. I've also rendered primers inert with a drop of penetrating oil. Both work. For a single one, unless it was a rare caliber, I'd shoot the bloody thing or simply inert it & discard.
