I am sure that additional length can add to velocity wspecially when going from 24 to 29 but I do not really believe it would be a great deal. My orginal 24" Remington says the max load is 120 grains... whenI quizzed a Remington tech about this limit - he indication was that any more powder than that it would be shot out the end of the barrel. The longer length of thebarrel will allow more powder to be burned more completelycausing an increase in velocity.

Here is the problem in my mind... Shooting BP or sub the powder can vary so much in just itself that loosing or gaining a couple hundred FPS is done almost every shot. The common thought is + or - 5 grains will not causea great deal of difference in FPS.

Shooting the 24" Remington and the longer rifles that I have 28" - really I do not see a lot of difference in velocity.

The last point I should say is I do not weight loads - I throw them by volume - if I were weighing each load the difference may be greater.
