With use of 1:8 in a BR and +105- bullets, velocities will be in the 2700 to 3000-fps range.
Using velocities from this range and you can expect to get 25-fps change in velocity for every 1-inch of barrel length.
A 30 inch barrel should give you at least 100-fps more then a 26". A 21" would be at least another 125-fps less then that.
Hope this helped....Happy Shooting
