Re: Annealing Accuracy Increase???
I use the Bench Source and it is an excellent product that enables you to get very high precision in the annealing process. I haven't seen a difference in accuracy when measured at 100-200 yards, but it I have found that case life can be increased, and my ES seems to be maintained. Keeping ES as low as possible would give more consistent accuracy over the life of the case at extended ranges. As you continue to fire and resize the brass the neck area becomes work hardened and in time can become brittle and crack, as well as produce an inconsistent grip on the bullet. This inconsistency can many times be felt when seating your bullets. I can get 10+ reloads with my 6.5 x284, 308, and 300WM by annealing.
