I anneal based on a method that was popular on this august forum back around 2006.
I work in a dark room. I use a propane torch, and a pie pan full of water. I hold the brass in my fingers and heat it with the torch, turning it as I go. At the merest hint of color, I release the brass and it falls into the water. I also count slowly. Let's say I'm seeing color at Ten. The next round, I'm ready to release at 9. I know if I get to 11, I'll burn my fingers. After I'm done annealing, I'll either pop the rounds in a toaster oven at 300 for 20 minutes to drive out the water, or I'll place them in the vibratory cleaner with corn cob.
I've done quite a bit of brass since 2006 of all sorts and sizes. No splits. No problems.
