A QUOTE:
I've never seen anything in print showing anything close to 75 fps/inch loss in velocity. According to a Remington ballistics chart I have.

If your muzzle velocity with a 24" barrel is within the following ranges either add or subtract.

2000-2500 10 fps/inch
2500-3000 20 fps/inch
3000-3500 30 fps/inch
3500-4000 40 fps/inch.

Rifles are individuals as well. It is not unusual to see a 22" barrel from one gun shoot the same ammo faster than a 24" barrel in another gun.**END QUOTE

Now, there's someone who has, quite obviously, studied the subject and done RECENT research!
