[QUOTE="Mikecr, post: 394937, member: 1521"] Loner, When I said "Annealing doesn't restore tension, it relieves excess", I should have said simply that 'annealing relieves excess springback'. Actual tension produced is relative to your conditions. As with anything there are atleast two sides, with extremes.. In your example, excess springback from many-sized necks is reducing bullet grip. The brass is so hard that sizing will not take. So annealing reduces the springback to a point where there remains enough bullet grip after sizing. But annealing will not always increase 'tension' (bullet grip). If the brass is not excessively hard at the time of annealing, then it will lose tension with annealing. In fact it can lose so much from annealing that it will not hold a bullet from one sizing. This is balancing of context regarding 'tension' (bullet grip), and springback (hardness). Springback is flat out reduced by annealing. Tension left from annealing is either improved or worsened. Depends on your conditions.. [/QUOTE]
