[QUOTE="J E Custom, post: 1278118, member: 2736"] The RUM case would just barely work for a .510 dia bullet because the case body at the body shoulder junction measures .525 and for all practical purposes the shoulder would be non existent making head spacing marginal. you could AI the case and go to .535 with less body taper and end up with a shoulder of 12.5 thousandths (Still very little). I looked into using the 50, 45, and the 416 and came away with the 416 as my choice of a boomer for many reasons. I have never regretted my choice and It is one of my most accurate rifles, with the best group @ 100 yards being .034 thousandths 3 shot group.(34 thousandths larger that the bullet Diameter with a 400 grain bullet @ 2700 ft sec for all the power I need). Here is the rifle and some of the earlier specs. and pictures. [url]http://www.longrangehunting.com/forums/f28/416-buff-21003/[/url] J E CUSTOM [/QUOTE]
