[QUOTE="J E Custom, post: 472298, member: 2736"] The 450 Rigby is a very large case and will exceed the 458 Winchesters energy and velocity and has a bolt face dia. of .589. The 500 Gibbs is a large rebated rim case with a bolt face dia. of .575. The 505 Gibbs/ Cheytac case uses a larger case head .635 and normally requires a custom action like many other big dangerous game cartridges. The 416 Barret is simply a 50 BMG case shortened and necked down to hold 200+ grains of powder the 50 BMG holds 250+ with a bolt head dia . of .804 and requires a special action There are some cartriges that hold more powder than the 505 case but they all have a large case head and require a large custom action.
