You're estimation is off a bit...

My Remington Model 7 in 300BO has a 16" barrel, shooting Speer's 150 grain bullet (#308150BLKGDB) I get approx. 2,150 fps using Speers load data for Lil'Gun. Granted this is the only powder they list as doing 2,100+ fps.

Regarding Speers load data, my results are pretty close to their velocity, except with Accurate 1680, which is a little faster in my rifle.

So, getting 2,150 fps in a 300BO, I'm confident that 2,300 fps in the 300 Ham'r should be doable... But I would like to see some real world data.

It's often the case that the most accurate load is less than maximum. If they list 2154 fps as maximum, the accurate loading is quite probably somewhere around 2100 fps. Also, I don't usually want to be on maximum, unless the pressure isn't close to maximum (such as when the case is full). Do you know what barrel length Speer is using for its figures?
