I bought 500 rds of Remington 25-20 WCF brass, when such a thing was available, and loaded 100. 32 split necks on first firing, aarrgh! candle annealed new brass, next 100 fired with same load and zero splits. With Lee collet dies I anneal every other firing, and usually drop hot cases into a bath of water with citric acid and dish soap, then put in ultrasonic cleaner.

There is no retreat but in submission and slavery!
