I have loaded the 150 gr. LRAB for my son's 7mm Rem. Mag., using IMR 4350 powder, with 3200 fps mv out of a 24" Douglas Premium barrel. This is not a maximum load, according to Nosler's load data.
Go to the Nosler loading site, and take a look at their results and recommendations for different powders- IMR 4350 is shown to have given the best velocity results of all powders using their 150 gr. bullets.
Accuracy with this bullet in my son's rifle is sub-MOA.
Getting at least 3100 fps with this bullet should be no trick at all, assuming decent barrel length.
