Anything past 18" will make no difference on the pattern. Only difference is they will swing different etc. I used to shoot a KX5 with a 34" now shooting a K80 with a 32", cant really see any difference. The gun always does its part, wish I could say the same for myself.
Will a longer shotgun barrel shoot farther?
Modern smokeless powders burn in the first 13 to 16 inches of the barrel and maximum velocities are obtained in the first 20 inches. Shot will carry the same distance regardless of the barrel length. Shot pattern will be the same whether the barrel is 21 inches in length or 30 inches in length, if the barrel has the same choke constriction.
Our experts state there would be a small variation in velocity when using a 21-inch barrel as compared with a 30-inch barrel; however, the variation would be immeasurable.
The basic advantage of a shorter barrel is that it will swing faster. The longer barrel gives the hunter a longer sight radius to be more precise, particularly when pass shooting waterfowl. Also, the longer barrel can often help balance certain shotguns better.
Extra barrels are listed in the Products - Shotguns section of our site.
Yes, that'd give you an unfair advantage over the other shooters. I think the ATA should address this obvious oversight in the rules.
I propose adding a rule;
Section XIII, F (guns and ammunition), 1 (to include the following) "shotguns with longer than 34 inch barrels shall not be allowed except in the case of extended choketubes that protrude no more than 1 inch beyond the muzzle shall be allowed on 34" barrels."
hawk57- Two inches will add weight to the end of the gun and this weight will slow down the swing speed and make it more difficult to stop the swing. For most, it will also make the swing a little smoother. Remember three ounces added at the end of the barrel will feel much heaver than three ounces added at the trigger.
Also, aiming a shotgun is a bad habit, but recognition of the bird bead relationship is important.
My 34 inch BT99 is 8lbs 5oz and 51 inches over all. My 30 inch XT is 8lbs 11oz and 47 inches over all. So, according to your statements my swing should be slower and smoother with the 30in XT over the 34in BT99 because it wheighs 6oz more? Even though the XT barrel is 2 inches shorter and (over all) 4 inches shorter than the BT99?
According to Dick Bennetts book, "Trapshooting is a game of opposites", for each 1" of barrel length over 30", the payload will increase by 10fps or so. A 1200 fps load out of a 30" barrel would be about 1240fps out of a 34" barrel. I proved this theory for myself, after reading Dicks book, by chronographing a 30" Perazzi O/U barrel with a .725 bore and a .693 choke (.032") and a Perazzi 34" single with the identical bore and choke. I used the same 3dr. Federal 71/2 handicap load. I test fired each gun 10 times over the chronograph and in each instance, the 34" barrel was 32-46fps. +/- over the 30" barrel. While I realize this test is far from scientific, the facts are there.......Dan Thome (Trap2)
