I run two loads in my 7-08.
1. 140 gr. Barnes tsx with fed 210 primer and 47 gr. H4350
2. 150 gr. Nosler BT with Win. lr primers and 49.5 gr. Ramshot Hunter

Both shoot very well and deer go down quick.

I am sure GMX would work just as well. It is all in what you want to shoot and that shoots well in your rifle.
