[QUOTE="Fiftydriver, post: 115780, member: 10"] Roll-yur-own, Basically it is an improved version of the 50 BMG but with the Allen Magnum shoulder configuration instead of the Ackely angle. Shoulder diameter is increase quite a bit over the standard round. Headspace is 4 thou shorter then the standard BMG so standard BMG ammo can be fired in this chamber safely and accurately. I figured there was no need to get to exotic with moving shoulders foward or anything so its basically just a version of an improved 50 BMG. Kirby Allen(50) [/QUOTE]
