Do you put anything in the primer pocket to absorb the firing pin?  I've thought of some of that shoe repair goo that dries clear and is rubbery type where it stays pliable.  Thoughts?

I just buy a whole pack of snap caps....

but, if you wanna make your own...I'm sure some rubbery adhesive will work. Maybe a dot of latex caulk or something. Or shoe goo.

Yeah, for training purposes, why not just get commercially made snap caps? They’re also usually funny colored to ensure there’s no risk of mistaking them with live rounds. Reduces the risk of things getting Rusty.

That said, for realistic looking dummy rounds, what’s wrong with simply popping/firing the primer after removing the bullet and powder, and leaving the dented primer when reseating the bullet?

I have a block eracer I use with empty cases to cookie cutter a rubber plug that fits the primer pocket.  Been a long time and can't remember the case used but I extreme outside bevel a case.
  Drill out the primer pocket of case being used to make cookie cutter plugs .
 Slice off the eraser block a primer thickness slab.

Now you press mouth of case into eraser and spin or turn and create plug.
Push plug out of case neck through drilled primer pocket allowing rod,bamboo stick to push it through.

They don't have the same weight as dummy rounds for full mag reload practice.  And I know you aren't using live rounds in practice, right?

I leave the primer out for safety.  No primer, no bang.  And I knew it was a dummy round and not a squib.

Forget the snap cap.  Modern handguns can handle a shitload of dry firing without damage.

And if it breaks, replace it.  It's a tool.  Not a beautiful artifact for staring at.

I mean, you do you, but snap caps are cheap as hell nowadays.

Also, per your post,

I'd rather "waste money" on snapcaps than "And if it breaks, replace it.  It's a tool.  Not a beautiful artifact for staring at."

Thanks for the responses.  The reason I’d prefer not to have regular snap caps is i want the weight to be the same for reloads and feel.  It’s not just one snap cap in the gun as that wouldn’t make a difference but a mag full with it or a moonclip full.  

Thanks!

This.

I had a friend make up some X39 dummy rounds for me. He soaked the rounds in WD40 to kill the primers, then drilled into the casing and got all the powder out.

When I got them from him, I soaked them longer in WD40 bath, then went through them with my nastiest AK clicking off each one. Had a few small "PFF" from a couple primers but nothing serious.
Every single one of them has been useful and has been used dozens of times now- never an issue with not fitting or having bullet fall out, etc. Cannot say that for every other commercial option I've bought over the years.

These are great for mixing in with live rounds to induce jams during training. Have a friend load your mag so you can't game it.

We found some 5.56 ones on Ebay and used them at a dry work class we do with a combatives group. They worked a little TOO well, LOL. Induced some rounds stuck in chamber and bolt overrides. Being as most of the dud rounds will just induce FTF and nothing more, we will mix in these with others to induce more serious malfunctions.

I use fired cases with a 1/8" hole drilled thru near the head.seat an extra bullet and mark the OAL . I have used various primer fillers - silicon caulk, spent primer, nothing, epoxy, silly putty...

I found some white delrin rod the size of primers that I cut and install in the primer pocket.  I fill the cartridge case with #9 shot so the bullet can't get pushed into the case.  I can't recall where I got the delrin rod.

My CZ came with dummy rounds and replaceable green rubber primer inserts.  Someone likely makes these.

Google up some Snap plug .

I've been using the same orange plastic dummy rounds for decades.  Bought a bag of 100 at a gun show back in the 80's.

For dry firing revolvers, it's not a dummy cartridge but a nylon disk that fits on the extractor star.
