Been shooting 44 hot loads since 1970. Those look normal for a hot load and I wouldn't recommend a steady diet. Occasionally to keep the feel of recoil maybe but that BB load is more for charging buses than bears. hardly necessary.
Now if your brass starts to come out of the cylinder looking like these, you had better give BB a call.
Before everyone starts jumping up and down, I posted this as an example. I never was able to figure out what the problem was, but most likely is was a brass issue---combination of old brass and hot loads or possibly even a bad batch of brass. These were all the same head stamp so I always leaned towards bad batch of brass. I still have 70+ pieces of it in similar condition. Lots of guy figured it was my polish being something containing ammonia, but the only polish I ever used was Dillon's. So it will remain a mystery.
