Load data for .460 Magnum w/275gr Barnes XPBs?

[EddieCoyle]

Can anybody help?

I've found data on Hodgdon's site for the 200gr XPBs but nothing on the 275s.

Looking at the long bearing surface of these solid copper bullets makes me hesitate to mess around with guessing.

I'd like to use Lil' Gun or H110/W296.

Email Barnes, they probably have some data they can send you. I've had to contact them for things like that in the past and they're very responsive.
