Nice.

Now what would be the difference, ie in game hunting, between a .450 and .500 in BPE?

Medium game for the .450?

Perhaps tiger for the .500 as well? Would it stretch to buffalo and gaur?

Probably a little too light for elephant"

ie it is BPE not NE.

Again nice pair. Nice engraving on the plates as well.

Do they both fit in the same gun case? If so, anyway, please take a photo of the opened case with guns inside. Thanks.
