[QUOTE="yorke-1, post: 1666675, member: 11960"] The 30 Sherman Mag dies showed up today, so I took a second to form a couple pieces of brass and get some capacities. These are usable case capacities in grains of water with a 212 ELDx seated to 3.690" in 300 Win Mag, die formed (not fireformed) 30 SM and 300 RUM cases. I chose that OAL because that's what will reliably feed from my AICS mags. [img]https://i.imgur.com/AoPK7ZG.jpg?1[/img] The 300 Win Mag and 300 RUM cases are once fired. I'm not sure what the capacity difference will be between a die formed 30 SM and a fireformed case, but I imagine it's within 2 grains. [/QUOTE]
