When is a 12g not a 12g.

Before I had a pair of plastic snap caps I wanted

to test my new gun so I picked up a few used cartridges

out of a pile of used ones in a skip at a clay shoot site

I use (Id forgotton to keep a few of my own empties).

 

When I got home and after cleaning I tried the used carts

in my gun and when I tried to close it up both carts failed to go

into the barrels. I took them out swapped them around and

tried several times in the end I bent the brass casing base

of one of the carts and it jammed in the ejector.

 

I was worried as you may imagine. I placed two unused

carts in the gun and they were fine.

 

So long intro to a quick question.

 

Do some guns vary slightly in breech diamiter enough to

cause the cartridge base to expand enough not

to fit into another gun?

Or could the other gun be warn slightly so the carts were

expanding beoynd the limit of a normal 12g?

 

Thanks taz

Yes taz the cartridges do expand when fired so they wont fit into a gun, the brass section expands to the chamber size of the gun it was fired from.

 

A new cartridge in slightly smaller so it fits. Even a catridge fired from your gun may not fit back in later.

That is why when you reload it is imperitive you 'resize' the case, to counteract the expansion.
