[QUOTE="Fiftydriver, post: 277626, member: 10"] JackRabbitSquare, Something like this? [IMG]http://i8.photobucket.com/albums/a7/Fiftydriver/50BMG510AllenMagnum50AllenTactical.jpg[/IMG] Left to right, standard 50 BMG, 510 Allen Magnum and then 50 Allen Tactical, all loaded with the 750 gr A-Max. There is more to an improved 50 BMG then just shooting a standard 50 BMG round and ejecting a fully formed improved round. The shoulder/body junction needs to be annealed very well or you will never get a sharp shoulder on fireforming, brass is much heaiver then conventional cases and pressures are far less then most modern conventional magnums so you need a soft shoulder to blow out fully. Also, the brass on the BMG is thick. Blow it out to reduce body taper and it will increase sizing pressure needed to FL size it and because of the size of the round, you should FL size your brass everytime to insure easy chambering. You do not need to bump the shoulder much but just enough to chamber easily. If you accept these few things, the improved BMGs are fun to work with and rewarding for sure. [/QUOTE]
