Hi,
Hew member question.
I purchased a M76 rifle kit a few years ago which included the barrel.
The barrel chamber has a problem. When a cartridge is inserted it does not go far enough in to the chamber.
The extractor groove on the cartridge lacks about 1/16" to seat.
I painted a couple of cartridge necks with dye including a portion of the projectile and forced it to seat.
I removed the cartridge and took some pics of the dye transfer, which I have Included in the post.
It is obvious that the chamber was incorrectly cut.
My question is, does it need re-cutting the chamber, or does the throat need re-cutting?
I checked the headspace with gages, which is ok. Also I used new steel case, and some circa 1950 Greek ammo.
Thanks for your help,
