    The 300 wsm is a very efficient cartridge using faster burning powders than most magnums. For that reason it would not gain as much with longer barrels. I have not tested it though so could not get you a number. An educated guess though would be less than 25 fps per inch. I would guess 20-25 per inch.
    Predictions are difficult, especially when they involve the future

    Since you stated 3000 fps for a 300 WSM I assumed a 168 grain Hornady A-max and Hodgdon H4350 as that's a "factory pressure" load according to Quickload which gives close to 3000 fps. By adjusting the load a bit to give exactly 3000 fps then changing the barrel length from 24 to 26 inches Quickload showed 3055 fps. Changing the bullet and powder could give a range of answers, but that's in the ballpark.
    ( close to LTLR's educated guess)
