A bulge in the case usually means there is an issue with the round being smaller in diameter than the chamber. When the round discharges the case swells.Cynful1958 wrote:I did keep all the shells, about half of them had a bulge in the cases. Is there anyway to find out how old bullets are ?
Are you sure the ammo you are shooting and the gun are the right match?
This is really the only way a case will "swell". Like shooting 9mm in a .357 sig pistol. It will shoot fine but the shells eject looking pregnant. I witnessed this with a shooter at my IDPA club. He forgot to change his barrel from .357 sig to 9mm. Everything worked but we all noticed the odd looking cases that were ejecting out. With a revolver, it seems like you would notice a cartridge rattling around in the cylinder if it was too small.
Sometimes with reloads, if the brass has been reloaded too much on the +P side of the recipe, that can also cause the case to split. I've seen this when I was reloading rifle rounds as a youngun. If it's factory, I wouldn't think that would be what's going on.
I would definately write their local rep and let them know what's going on.
