For my favorite guns I buy Lapua. I have loaded 10pcs. 26 times. The other 90pcs have about 10 on them. I am trying to see how many time I can load them before I get the first split neck or case head separation. Hasn't happened yet. They have been annealled by me 3 times in that period. At 100 rounds for $50+, it is still a good buy. I get about 15 loads out of winchester and less with remington brass. All .223 brass. I make my .260 brass out of Lapua .308. I'll probably buy 2 barrels before I wear out the brass. I don't know why it is better, it just is. Primers stay tight with hot loads (not stupid hot). Norma brass is good too. Hornady Frontier is excellent if you can by it for your caliber.
