[QUOTE="Autorotate, post: 382478, member: 8073"] jessej Those velocities are very obtainable in the barrel lengths you mention. By the load data Wambo and TH are posting, I'm guessing those case designs kept the shoulder angle/body taper about the same as the SAAMI case. The Improved designs, like Kirby's and the 30-338 Lapua that JE Custom built me, add quite a bit of capacity, about another 10-12 grains, and the load data reflects it. [URL="http://www.longrangehunting.com/forums/f53/je-custom-lone-wolf-30-338-lapua-improved-weatherby-mark-v-54231/"]103 grains of Retumbo is where I settled on out of 26" barrel at 3280 fps with a 210 VLD. It's seen well over 3400 fps with no pressure signs, but found a great big accuracy node at this velocity level, and it had all the performance I needed, so that's where it's at for now.
