[QUOTE="7.62 Gunner, post: 2784417, member: 121641"] There's always bad info about short barreled magnums spewing unburned powder out the muzzle. The powder burns in the first several inches of barrel, people confuse gas expansion with burning. You won't need anything faster than a 9 twist to stabilize bullets longer and sleeker than a 215 at velocities above 2600 fps. Depending on your velocity goals I'd go with a 30 Nos if using a standard magnum action, or a 300 NMI if you're into trying a lapua action. I'm sending 225 eldms over 2800 fps with Retumbo in my 19" 300 NMI. N570 would easily be north of 2900 [/QUOTE]
