I was going slightly nuts till I figured out this one. It does not happen with 38 special brass, but manifests itself with 357 mags.
I was unable to chamber the rounds in My Smith 19 and Rossi M92 rifle. The last 1/4" of the cartridge would not chamber. One out of 10 would chamber fine. The problem was on the bullet end. No matter how lightly belled I made the brass this problem would occur. Using a roll crimp made the problem worse. Omitting the expanding operation fixed the problem. Later I found that some RP cases were not gripping the bullet tight enough so I bought a taper crimp die.
Much later I found that I could get rid of the chambering problem by using the taper crimp die with a very mild crimp. So finally I can bell my cases to start the bullet easier and also tighten the grip on the seated bullet.
I was wondering if anyone else has had the same problem.
