Hi all,


I bought a TD carbine made from a rifle with original carbine barrel and loaded up some 405 gr. cartridges a la Wolf. I used 55 grains of compressed FFg, drilled out the primer hole and used Winchester standard rifle primers, and Lee 405 gr. 20:1 HB bullets. After firing them I noticed a bulged ring around the case at the location where the base of the bullet starts in the loaded case, and the primers are backed out. The cartridges almost resemble a bottleneck cartridge because the neck for the length of the bullet seems to have not swelled like the rest of the cartridge. After re-sizing them there is a scribe type line in the brass where the bulge was. I'm afraid these cartridges will seperate if fired again. The chamber has a narrow ring inside corresponding to the location of the bulge in the cartridge.

Is there anything that can be done short of a replacement barrel? Is 55 grains compressed too much? Should I go to Magnum primers like I use in my 500 gr. .45-70's I use in my M1884 Springfield rifle?

Any help would be appreciated as I can't afford a new barrel right now and don't want to hang it on the wall.

Thanks in advance! John

Hi Andy,


I solved the problem last winter. I sent the barrel and receiver to Phil at S&S Firearms and traded it for a correctly cut and turned down tapered rifle barrel with new front sight. The original carbine barrel was ringed before I bought it in the first place, but it had a dark chamber and I'd never seen nor heard of a ringed chamber before. I have heard of bulged barrels, though. Anyway, my loads work just fine in this unringed chamber.

Thanks for replying with your ideas, though.
