Probably came from one of Muzza's brother-in laws.
After all what are family for.

Had an occasional misfire problem with my newly acquired 222 Rimmed Cadet , so being a clever cookie I took it to my erstwhile gunsmith mate . We pulled the action apart , cleaned the gungey crud out of the works , polished the firing pin slot and matching sear-bit thingy and reassembled it . ( Those Westley Richards actions are different to the BSA ones...) Now we have misfire , pierced primer , missfire , missfire , give up .

Any ideas before I attack the internals again ? It was shooting very well , even for my handloads , and I was going to take it goat culling this weekend .

Thank heavens for the Cadet K-Hornet and the other new toy - the Rolling Block .303 x 39.

Muzza,
Your problem is one of three things:

1) Firing pin too long. If the smith has turned down the firing pin the force exerted by the spring now happens over a reduced nose area so the darn thing drives well into the primer resulting in a pierce.

2) Misfires could be caused by primer seating depth as the 222 rimmed brass has very deep pockets and you may be seating them too deep. Secondly, use a square edge across the block face, sometimes when bushing the firing pin holes the bush is seated too deep resulting in a small crater across the face

3) Primers vary in cup hardness, I don't know what brand you are using, but my 17AH only like Rem 7.5's because the clearance between the firing pin and the hole in the breech block is a bit sloopy and the fired primer tends to flow into this little crevas and jam the whole action from opening.

Hope this helps,

Easy answer Muzza with a thing like that just use it as a fire poke and you wont need to worry about misfires..if it's come from kiwi you can bet your balls the bastard who sold it knew it was fucked...

Thanks BAW , I figured you might have some knowledge there. As for those two other examples of used dietary fibre - thanks boys , you can go back to the playpen now and break some more of your toys...

My .222Rimmed shoots like a dream.

Wet or dry; with or without a breechblock installed?
