[QUOTE="Elkeater, post: 1642657, member: 103670"] Yup. Hard to beat hammers. Other than that in a magnum cartridge I just run one round from minimum charge up in half grain increments till I find pressure then start testing top few charges. Example: in my .300winny I started with 181 hammer hunters in nosler brass, Fed215m primers and loaded the rounds to max mag length. I started at 75grains H1000 and worked up in .5 grain increments until I hit 81.5 grains where I found slight pressure signs. I then picked 79, 79.5, 80, 80.5 and 81 Grains and shot three round groups at 200 yards with each load. 79 shot 1 MOA 79.5 shot .8MOA, 80 shot .6 MOA, 80.5 and 81 opened back up. Picked 80 grains the tweaked the loads from max mag length down in .015 increments til I hit .3-.4 MOA with 3.505” COAL. There load development done in about 40 rounds. Honestly probably could do it in less. Just the way I do things. It’s safe, fast and straight forward which with kids and a job is all I can ask. [/QUOTE]
