[QUOTE="ProBusiness, post: 785260, member: 6145"] -------------------------------------------------------------------------------- [COLOR="Blue"][I]Velocity will be lower in a shorty, so the pattern is wider. I love short barelled shotguns.[/I][/COLOR] i have to disagree with that. modern shells/powder reach max velocity at 18". with screw in chokes, an 18" barrel with a modified choke and a 28" barrel with the same choke will have the same spread. before screw in chokes, you saw 36" duck barrels. the extra length of the barrel made for a longer choke built in the barrel. the tigher choke kept the shot closer together longer so you had a possibility of killing a duck at a greater distance. but it DID NOT speed up the velocity of the shot. before screw in chokes - if you cut off the barrel BEFORE the choke you were left with a cylinder choke. this is the widest spread you can get. so a shortie had a wide spread because the choke was cut out of the barrel. Now, the pellets coming out of this shortie had the same velocity as shot coming out of a longer barrel. for the shortie - the fact that the spread was bigger did slow down the shot. shot traveling at 1325 feet per second traveled at 1325 fps regardless of the choke. velocity- velocity is not influenced by the barrel (as long as you have 18", under 18" max velocity is not reached). velocity is caused by the shell, i.e. the powder used and the amount (weight) of lead. a shell rated at 1325 feet per second will shoot 1325 feet per second from an 18", 20" , 26", 28", 30" barrel, makes no difference.
