Watch that CFE223 if you haven't worked with it already. I used different components that Hodgdon did for some 308 loads, so I was conservative in my approach. Even then things were sporty pretty quick.

For example, Hodgdon's start charge of 46.6 grains under a 168 SMK gave then 2662 fps from a 24" test barrel.

From the 24" barrel of one of my 700's I got 2750 fps with PPU brass, 168 Zmax, and WLR with the same start charge.

It's hot down here these days, but the range firing line has a roof and the rifle and cartridges weren't hot, having been in an air conditioned car just before.
