I want to make some snap caps for a 450/400 3". Midway just has the 3 1/4".

What do you substitute for the primer that will last?

I have heard of pencil erasers but that seems like it would wear out quick???

Palmer....been thinkin' the same thing.....wondering about pencil eraser or a semi-rigid type of caulking. First one to figure it out, tell the other....deal??

I have done it with just plain old silastic sealer.

"uhmw" ultra-high molecular weight".... cut it with a punch.. it comes in sheets of vary-ing thickness... drill the primer pocket out bigger than a primer, deeper too...

Call David Little at Kynoch and get some proper ones. He is a great guy plus you can order some wads from him as well.

I AGREE WITH 470 EVANS.

OR, JUST PUT THE HACKSAW TO THE 3 1/4" ONES !!!

It is possible to buy lengths of O-ring material that can be made up into a O-ring by supergluing the ends together. I made up some shot gun snap caps with this, just dug out the guts of a spent shotgun primer & epoxied in a piece of this, you could try similar to make up some snap caps for your 450/400 3". Boxer primers 5.3mm diameter. Some 5mm O-ring material would suffice. Its tough & won't break down in a hurry.

I have drilled and tapped the primer pocket and screwed nylon screws in the hole and then cut and filed the screw off almost flush. Last quite a while and can be replaced when worn.

I already did that and got a lot of information. By the way, the snap caps were a little over 7 bucks each but with shipping and handling the total charge was over 27 dollars!

I stupidly assumed from looking at the picture that "bullet" could be pulled out, the "case" cut off, resized and then slip the "bullet" back in. I should have realized that "bullet" was a fake and was actually just part of the case.

So when I cut off the snap cap "case" and inserted a real bullet it is front heavy and does not feel right.

I am now looking for something of the right weight and balance so it will also be good to use to practice reloading quickly. A real case and bullet with a little walnut shell case cleaning material inside would be right for that.

Then to color them red with some markers so I don't get loaded rounds by mistake. Its too hot outside to shoot so this project is just what I need this week.

Thanks for the suggestions.

Come on Allen! You own a Jeffery and a Searcy and you gripe about $27? Hacksaw?! Make your own!? Geez.

I BELIEVE YOU WANT SOME " DUMMY ROUNDS" TO PRACTICE LOADING.

MY UNDERSTANDING IS A SNAP CAPS PURPOSE IS TO ALLOW YOU TO SAFELY LET DOWN THE FIRING PINS WITH NO FEAR OF BREAKAGE.

Nylon, acetal (Delrin), uhmw all work well.

Fired, decapped cases, with the primer holes filled with epoxy. I used the steel putty stick stuff from the hardware store--5 min cure--works fine.

My Father has made snap caps from these 8499A69 part# from Mcmaster-Carr. You can play around with the spring force.
