Just my .02, I tried the socket-drill method...50-50 chance of 2 cases being even close in results....unless you can control (consistently) rpm of case, distance of flame tip to case, and time.....then your tolerance stacking (things that can change) is uncontrollable.....do you have $60-80 budget? If not, and I understand that, then you are doing what you can....but maybe worse off than not annealing....here is a pic of a annealing machine I built, not professional grade, but I do get consistent results....one speed controller is for case fed, one for case-flame time...if you don't need case feed, it will run about $20.00 less....rsbhunter
