Have some once fires Federal brass in 38 Spl. Been shooting them in my Python, reloading with 158 gr. Berrys and 3.8 Bullseye. Many cases are split the full length, no problems with W-W or R-P. Not a lot, but when I lose an W-W or R-P, it's usually at the case mouth, after many loads. Anyone else having problems or is it just a bad batch of brass. Most have been loaded only 1 or 2 times.
