Allen-though I've never been across the pond, when I do go the combo of a 270 and 375 will most likely be the way I'll go as well.
I just can't imagine wanting for anything more, and we both know that if they don't get it done it isn't their fault.
I'd take my lil G33/40 in a .270 and my bolt magnum would most likely be turned into a 375.
Come to think of it I've a thinking about doing it anyway for work here at home and anywhere else I travel.
Personally I think it's a super idea!
