5 1/2 or 8 in. remi?
 

Could anyone tell me if there is a big FPS difference between the 5 1/2 in. and 8 in. barrels when it comes to accuracy and velocity, I understand there will be less barrel to burn powder but is the difference dramatic?

More accurate due to the longer site picture with the longer barrel, FPS should be faster as well since most of the powder will be burned.
