    Please don't flame and say just shoot; this is a straight up question to evaluate the physics of patterns at distances.

    I have a 30" and was looking for a 32" used but they are hard to come by.

    I know for 16 yard & 20 yard no issue. I can't say about 21-24 or more cause I'm not there yet. I have practiced at 23 and was still able to break targets.

    But for further yardages let's say anything from 25-27 when guys use a FULL choke 7.5 shot.....

    Does the 2 extra inches really make a difference? or is it something that using an EXTRA FULL choke can compensate for to give you the same pattern downrange as a FULL would?

    No difference in shell performance. It's all a weight and balance thing supplimented with a longer sight radious.

    I knew about the sight plane thing.

    I have shot 30, 32, & 34 and I don't see a difference.

    I was thinking is b/c the 2 extra inches is keeping the shot cup together a little longer if that would matter

    What SS said, if YOU think it will help, it might, but the target will never know the difference between shells--full choke--longer bbls.--etc. Point what you have now (your 30" tubes) in the right place & the targets will break, spend your money on a good coach & ammo. Ross

    This should make my gun shopping a little easier then.

    The 30's are more available where I am for some reason. Plus trap is not huge by me and there aren't that many places to shoot at so that along with the high overhead to stock expensive shotguns it goes hand in hand

    Quite a few guys travel and buy from dealers in NJ & PA b/c of this.

    But if you are a sporting or skeet shooter and wanted a semi you can find them no problem but O/U's are a totally different story

    Doesn't the extra length contribute to increased velocity?

    minnship8,

    Yes, but not enough to notice, or probably eaven measure reliably.

    How much FPS would you say?

    Interesting....

    But if lets say a 3 dram shell has a muzzle velocity of 1200 FPS that means it's more than that as soon as the shot is released. Am I correct?

    So let's say for as the shot goes off at 1250 (just a number) muzzle is 1200 or less (the choke has to slow it up some) then like you said it shouldn't matter?

    There is no measurable velocity difference between a 30" and 32" barrel. Heck, there is no discernable velocity difference between a 30" and 34" barrel. It'a all about weight, balance, and the sighting radious. Y'all are overthinking this just a bit. I wonder how all those targets got broken with a M12 or 870?

    No, it won't make you a better shooter either. 16 to 23 works well for you. That says you point them pretty fair at those distances, 25 to 27 and beyond calls for a LOT MORE precise pointing no matter the barrel length.

    A question on balance and smoothness. Would a tank with a short barreled gun swing any smoother than a long barreled one? Apply that thought to you shooting your shotgun.

    Properly made full choke will deliver full choke pattern performance reguardless of barrel length. Shotgun MV and pattern statistics are significantly variable. MV is difficult to measure exactly (how do you know you measured the same pellet at chrono start and stop?), etc. So, forget longer barrels shooting tighter, "harder," faster, etc.

    What a long barrel does is, all else being equal, raise the swing effort needed to point the gun in any differing direction. A gun will have two differing swing efforts; unmounted (between the hands) and mounted to the shoulder.

    The "trick" is to match weight, balance (teeter-totter point), unmounted swing effort, and mounted swing effort to you needs for best scores or most fun shooting. This is the same as you would do for stock dimensions. There is no right or wrong, good or bad. There is what works for you. Mounted swing effort tells you how fast the gun will start swinging, change direction, and stop once you stop pushing on it (a higher effort gun will cover for you better if you fall off your swing as you break the trigger); or how much extra effort you will have to expend for the same swing speed.

    rocketman100, you covered shotgunning pretty well from A to Z.

    Trapshooting isn't a complex game of angle swing. The max move may only involve a total of 40 degrees as an extreme on horizontal and less vertical moves. What about the shotgunner shooting trap becoming one with his gun? What's that mean? It certainly doesn't mean he's in love with it. To me it means, once he mounts the gun, the entire upper body(gun included) moves as a single unit to overtake and intercept the clay targets! Moving as would a tanks turret? So used, balance and barrel length is immaterial my view, especially in trapshooting. The only body part that moves independently once the gun is mounted is the shooters eyes! My post concerns the game of trap only but may be just as valid in others as well.

    Back in the 60's & 70's before the single shot became the trap shooters choice, a lot of people made the 27 yard line using a 30" Model 12 or an 870 pump gun.

    Me included.

    Hap, the muscle effort needed to "turn the turret" is more with a higher mounted swing effort gun. It doesn't take much change to be noticed by the end of the day if you are shooting 100's of targets. The morning's wand may well become the evening's pig on a snow shovel.

    Not using weight, teeter-totter balance, and swing efforts in you quest for a better (for you) handling gun is sorta like fitting a stock without a measuring (length) stick.

    I have fought the two different barrel lengths mentioned for many years. I have come to the conclusion that in an O/U, 30" barrels work for me.

    "Hap, the muscle effort needed to "turn the turret" is more with a higher mounted swing effort gun." SO, that means if the gun is a couple ounces heavier it's going to cost the shooter in muscle fatigue and a loss of targets? I know the rag writers have written volumes about a "perfectly balanced" shotgun but I never seen one of those guys shoot very much trap either?

    I do like my hunting shotguns to balance near the carry portion for ease of carrying and a tad easier to throw to my shoulder at the flush. My trap only gun is premounted before I call for a target? All that writing is out the door UNLESS the shooter is an arm swinger of the gun. Balance probably is important to such people.
