I had the same issue with setting up a 7mm-08 for a buddy. Here's a thread I started asking for 7mm bullet opinions. I think I would lean toward a 120 TTSX in a 7mm-08 and call it a day. There's a pic of a moose in the thread taken with that combo. If not the 120 TTSX, I think I would go 140 PT. I like to start the TSX type bullets faster than the 140 will go in a 7mm-08 if at all possible.

I know a lot of folks speak VERY highly of the .264's, but I just cant wrap my head around it for moose size game if other options are out there. But, that is strictly my head speaking. Never been after a moose, so I'm just passing along what my research has led me to.

With that said though, here's a link to a site detailling the viciousness of 120 TTSX in a 6.5. Go to the bottom of the hand-loading section under the barnes bullets. He tests bullets for a living, so I generally trust his input.
