I run the 155 scenar in both 308, and the 06
2875 in the 308, 3020 in the 06
This is almost exactly what I've found. My 1st gen ti is 30-06 and the load I keep on hand for it and what it's sighted in with is a 155 scenario over h4350. It clocked 3030fps from the 22" barrel.
My model 7 ss that I use as a loaner 308 has 155s loaded for it over varget and gets about 2850fps from the 20" barrel. It would probably do 30-40fps more from a 22" but 308 is pretty efficient so once you go past 20" you don't gain a lot per inch. If you're going shorter barrel anyways a 308 is a bit more efficient and does well in 20" barrels.
