[QUOTE="SLEDGE HAMMER, post: 1557918, member: 76860"] The Raptor case Bertrum has in stock now is longer than the Excal case but has the exact same case capacity. Not sure but I think the first ones Kirby got made had more case capacity, then Bertrum changed something ,maybe trying to make it stronger in the case head witch reduced case capacity!!!!! 114 grns of retumbo/2225 ADI Australian powder will get around 3150 with a 30'' barrel. or 125 grns of 50 bmg /2218 ADI for about the same. 123 grns of 2218 in a 28'' barrel gets 3080 mild load. 112 grns 2225 for the same velocity . the 2225 is temp sensitive but produces more case pressure so be careful . I have 2 Excals one 14 lb and one 9.9 lb carry rifle . I think Reloader 26 or 33 would be worth a try. [/QUOTE]
