I have the same rifle (Model 7 7mm SAUM, 22" factory barrel that Karl set back and fluted). Load is 60.0 H4350, 140 gr. Accubond, 3000 fps. Watch the 60 grs. My other 7mm SAUM (Model 700-24" barrel) will not "tolerate" that much powder. It sits at 58.5 grs of H4350.

For a magnum, I'm surprised at the low velocity. You must have a very slow factory barrel. My 22" 11 twist Shilen gets a hair under 3000fps with 10 gr less powder powder with 140gr Noslers, and groups regularly at 1/2". This is from a 7-08AI.
Someone commented that 3000fps seemed hot from a 7-08 with H414 and 140's. My 7-08AI hits 3075fps with 140's and H414. Accuracy, however, is not as good as the sub-3000fps loads with 50.0gr of IMR4381, IMR4350, or H380.
