[QUOTE="KH_Outdoors, post: 3076678, member: 123559"] Making brass & some initial forming loads. I'm using Lapua Brass for this project. It's very abundant and on sale even in many places. Plus, hey its Lapua! Necked up from 30 cal to 338 using a .307" mandrel then a .337" (dont forget the lube!). Quick hand chamfer & debur, they are ready to get primed/charged/seated! [ATTACH type="full"]560479[/ATTACH] For fire forming, I'm going to try and use up some old lot H1000 with 230 ELDX's. After talking to Rich, he felt that 80-82 gr H1000 with 230/225's jammed should be plenty safe. So after scrubbing the barrel & figuring out my OAL at the lands etc... built a few rounds to go test from 78-82 gr H1000. [ATTACH type="full"]560480[/ATTACH] [/QUOTE]
