Federal GMM 175gr matchking

[Chrisvierling]

Right now I'm shooting a rem700 sps in .308 that has a 1:12 twist in it. I've been shooting the federal GMM 168gr matchking bullets and have been getting an average of about a .6 MOA group. Anyone tried the 175's out of a 1:12 twist? If so what have the groups looked like?

The shoot excellent in my 1-12 Bartlein barrell F-class rifle.
