Making a snap cap

I was thinking of how I could do this. I guess you can resize an empty spent case, without puching out the old spent primer, and seating a new bowit.

How can this be marked to identify it easily?

Put a drop of red nail polish on the tip of the bullet. Or to match what is done today for toy guns, paint the entire bullet bright orange.

Cut out some pencil eraser or cut a piece of PVC the exact size and thickness of a primer and glue it in the primer pocket so the firing pin has something semi soft to hit. Paint the brass. Also you could use a very small drill bit and drill a few holes in the side of the case to give a visual indication it is not a live round.

You could use a really big drill bit, too. You can use a steel case to easily identify it if you don't shoot steel cased ammunition.

I don't think the spent primer will provide much protection for a firing pin if that is a concern with your particular gun. Use something that will slow down the firing pin without being damaged, like a piece of hard rubber. If your gun doesn't have an issue with dry firing, having no primer in the pocket would also help you identify the snap cap.

If the cap does not have a spent primer you might as well dry fire it; right?

I've filled the primer pocket with RTV and that lasts for quite a while.

Punch out the primer, fill it with an exterior silicone caulk and paint it pink.

Most 'home made' snap caps are useless. The goal is to provide a meaningful resistance to the pin slamming as far forward as possible so there won't be any internal peening. Pencil erasures, silicon rubber, etc are much too soft to absorb much of the energy before the pin bottoms out inside.

Or you could buy some AZOOM training rounds that act like snap caps and can in NO way be mistaken for a live round

What about filling the primer pocket with lead solder?
Or something like JB Weld?

I make mine by depriming and seating a bullet. Use to put 3-5 in about 10 live rounds and put in mag however I grab them without knowing. Then I go outside and shoot. Concentrate on best trigger pull as can. My dont have a primer or eraser to hit as I dry fire my pistols alot too. Aint worried about that either. Mine are used for seeing if the sights move upon when I do have a dummy round pop up, It helps me in that area.

I fill the primer pocket with Hot glue then use a razor knife to trim.
But the 3/16" holes are the important part of making a dummy round.
It will be nessesary to do some dressing of the case after drilling.
I have used a batch for several years now and the hot stick glued primers are in perfect condition. i believe them to be better than a snap cap, however i have a few bullets that are being pushed in.

buy a bag of snap caps in 9mm (cheapest) and use the extra rubber inserts that come with them in your home made rifle snap caps. If large primer rifle use a 45 snap cap instead. the actual inserts last for a LONG time.
