Thanks for all of the input.
I suppose the better question is whether I need 2,700 fps with a 180 in a 308. Clearly not for deer, but for bigger game animals, is it better to push a 165 Partition or 150 TTSX as fast as possible and forget about the 180?
This rifle has a 1:10 twist, FWIW.
Thanks again,
Okie John
