Yes, I have seen this in Winchester factory match .38 SPL,148 gr. HBWC ammo. They produced a certain lot of ammo with weak brass way back when. Is this Winchester brass?

I had a bunch of 44 mag that I reloaded about 25 years ago do that when I shot them last year.  Threw the rest away.  I can't think of why they did it, it was a relatively mild load.

I've had it happen in the past with brass that was either work hardened, or had been cleaned with Brasso. Brasso actually hardens the brass a bit because of the ammonia in the formula. Bottom line? The brass is a bit too hard and cracks when it tries to obturate and seal the chamber.

I would guesstimate that you have an oversize chamber.

BTW-- Ammonia in Brasso "dezincifies" the brass, thus weakens it.
