case separations
Hello all,
I've got 2 Miroku Winchester 73s in .357 that I've had a few years and have shot mostly .38s in them. I had them out the other day to shoot some .357s in to hunt with. I shot Buffalo Bore 125gr and some well below max 158 gr handloads. I got case separations in both rifles with both loads. The cases separated right in the middle. What would cause this?

RE: case separations
On the first shot or in a string? Sounds sort of like an oily chamber

Both. Hmm...…..I store them muzzle down, so that could be it. I'll swab them out and see what happens. Thanks for your response.

Use a brass brush and clean out the chamber to remove the carbon ring from the 38's

Thanks Lumpy. Did that too while I was at it.
