Annealing is for wildcatters and 99% of competitors who reload and shoot with stiff competition regularly.If this is you.....

Divide up a box of Lapua/ Norma or whatever brass. Don't anneal 50 and anneal 50. Make sure you shoot all of the brass the same number of times. Keep records. Measure each case before and after sizing, take notes. Feel the seating force on both lots. Take notes. Note group sizes after you have found a load. Then you will see for yourself. After 5 loadings come back and show us targets of each lot at 300 plus yards.
