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.
