I'm having to throw out some Lapua .223 Rem brass that I have loaded approximately 35 times each with a stiff load of Varget under a 75 Amax. Just think of all the hours I spent reloading on just this 100 pieces. I was able to lose only 2 in the 6 years I used the brass. I have annealed the brass about 5 times total including on the last reloading cycle. The brass necks are splitting and the annealing does not seem to help at this point. I had about 30 cases split necks in the last 2 firings and I'm going to scrap all of them. It is kind of sad throwing brass away that I have used this much. I never had a single case head seperation in this 100 pieces. It does feel good to know that the cost per round for this brass comes out to less than 1.5 cents after 35 firings.
