I am wondering if there is a chart some where of muzzle velocity of shot relating to barrel length? How short can a barrel be before you start loosing significant velocity? I have shot a police SBS that was an 870 with a 12 inch barrel and the velocity was very comparable to my 18.5 and 26 inch barrel guns only loosing about 50-70 FPS depending on the round fired.
p.s. purely for academic reasons. Though I may make a NFA SBS some day.
