LVJ76 ,,, that is an easy one ,,, the Lazz 7.82 Warbird and 30-378 Wby Mag share the same basic ballistic potential and rim diameter that fit into the largest standard bolt faces made ,,, the original design criteria for the Lazz Warbird, was to duplicate or exceed the performance of the big Weatherby but WITHOUT the big belt of the WBY, and headspace on the 30 degree sharp shoulder instead, for greater accuracy potential ,,,, the overall length of the Warbird is also slightly less than the 30-378 case ,,,,,
