I bought a Rifle Marlin 336 that had been re chambered from 35 Rem to 356 Win.Some fired brass came with the rifle. As I am processing the brass to reload I noticed a ring around the brass about 1/4" below the Shoulder.You can actually catch your finger in it.I took a few new brass used a beginning load and fired it.It appears this brass has started to do the same thing.does anyone know what causes this???Does re chambering not clean up the chamber and there is some kind of ridge there or maybe some too hot loads have been fired and ringed the chamber??Thanks ahead ,OB | ||

Normally that is caused when a chip is caught in the reamer. Sometimes(usually?) it can be polished out.

If the ring is symmetric, it could indicate a mismatch in neck dimensions between the factory and the .356 reamer. I usually find chip related damage in the body of the chamber rather than the neck. Either way, a chamber cast should reveal the culprit. _______________________________________________________________________________ This is my rifle, there are many like it but this one is mine.

When recutting a chamber the reamer is not exactly dimensionally identical to the one originally used. This will cause fired cases to show a "ring" where the merge is. Im certain thats what you're seeing. It's purely cosmetic and of no concern but this one reason I don't like to install short-chambered barrels. John Farner If you haven't, please join the NRA! | |||

Probably in the area of the case mouth of the 35Rem around 1.92" from the base. As John said cosmetic. Go shoot it and have fun. As usual just my $.02 Paul K | |||

Maybe I am not good at explaining but the ring is symmetric in the body of the case 1/4" below the shoulder of the case. | |||

Oops that rules out a different dia neck. The shoulder of the 356 is .454 the 35 .426 a reamer should have cleaned it up. Sounds more like a chip As usual just my $.02 Paul K | |||

My mistake, I had originally written below the neck when I meant below the shoulder.An Old Timers moment!!! | |||

It's funny, when I first read it I thought, "oh, he means below the shoulder." I'm interested to hear what those with more knowledge think that you should do.

That's quite the gift you have. It would come in handy when dealing with the fairer sex.  Shoot it a while and see if is a problem. If the mark is simply cosmetic, you can try to polish it out, but be careful, you can jug the chamber and have problems with extraction. If it's a problem, then you'll have to figure out if you can set the barrel back enough to clean it up. In all likelihood, the only trouble it will cause will be emotional. _______________________________________________________________________________ This is my rifle, there are many like it but this one is mine.
