doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Soft primers?

A while back there was a discussion of some doubles being hard to open because of firing pins hanging in the primer. Problem was solved by changing to another brand. Does anyone remember which was the hard primer and which was the soft? Had this problem with a new CZ Ringneck today. Chedite primer. Thanks.

Tony, I have read that also about cheddite primers. I think from my own personal experience of shooting some 25000 or more cheddites, it must be individual guns. I have never had a pierced primer or stuck firing pin in at least 15 different guns. I do remember that those with problems with cheddites, solved the problem by going to Win. 209's.

In my experience switching to Remington primers(from Winchester) cured the problem your speaking of. However it won't cure a firing pin thats too long or the incorrect profile.

Thanks, LLemke and Ken. I had this problem before with a Midland sxs but couldn't remember if I switched from Rem. to Win. or Win. to Rem.

Cheddite primer is the softest of the bunch.

I would examine closely the bottom edge of both firing pins when
they are fired and protruding from the breech face.If this area
is not nicely rounded and smooth it can cut into and bind with the side of the primer indentation and make the initial opening of the gun difficult.You can correct this by cello taping the face of the breech to avoid marking,with the pins protruding,and then either
filing or stoning the bottom edge of the pins.This has worked for me several times. Terry

This may help, but only if someone knows what kinds of primers are used by these manufacturers. I recently replaced a firing pin in my 20-ga. Superposed. On the skeet range, it immediately and consistently began hanging up on Estate shells. I switched to AAs and it would then hang up only about once a box. I still have a problem, though, as I want to be able to shoot whatever kind of ammo is on hand.

Terry, can you explain a bit more about your procedure? I'm fairly handy, but no gunsmith. The pins will remain stationary enough that you can lightly knock off a squared edge, all without disassembly? What kind of tool is used for "stoning"? I've always pictured something like an oilstone for sharpening knives, but you're obviously talking about a precision operation requiring something small and handy. Thanks. TT

My L.C. Smith is a real bear to open if I use anything but Remmie primers, but I've never tried Cheddites.

Not Terry, but for the stoning in place, I believe one would have to have the gun apart with hammers down thus keepimg pressure on the pins. Small Arkansas stones are available in many sizes & shapes, doubt you would want to use a large knife stone for this. Will sit back now & let Terry add any other details which may help you.
