[QUOTE="dmax1800, post: 960043, member: 68255"] I used a vibrator, not a tumbler. I vibrated it for about 2 hours, then put it in a sonic cleaner, then tried to size it. I only annealed it after I found out that I couldn't bump the shoulders. After it was annealed, I could easily bump the shoulders back. The brass had only 1 firing since it was last annealed. I use a propane torch to anneal the brass. I heat the shoulder while turning the brass with a cordless driver. I heat until the case mouth just starts to show the slightest hint of orange, NOT red and quench it in distilled water. I have also used 650 degree tempilaq on the inside of the case mouth as an indicator. The previous batch of brass had 14 firings with annealing every 3rd or 4th firing with ABSOLUTELY no split or cracked case mouths. Would it last that long if I was not annealing correctly? [/QUOTE]
