Every time, it’s step one of my brass prep process. I shoot only the best brass I can find, so if Lapua makes it in the caliber I’m loading I buy it. If not then it’s Peterson, Alpha, Norma, and ADG, I like lake city for 556 and so far hornady is the only source of brass head stamped 6ARC and currently you have to buy loaded ammo to get it (Hurry Up Peterson we’re waiting).
know I can make it last up to 15 or 20 reloads if I don’t load to maximum Charges and I anneal. When I get back from practice or a match I dump my brass into a large bin. I hate brass prep so i Put it off till I run out of prepped brass to load. I’ll dump it out, sort by caliber and flame anneal in large batches. Then pin wash, dry, resize, mandrel expand, trim, chamfer, and prime. Then I store them in 100rnd ammo boxes. When I need ammo i pull a box of brass and a box of bullets off the shelf, throw the powder and seat bullets.
