    I have a fixed choke trap gun. I'd like to be able to close my pattens up a bit for practice and then open slightly for league scores. Are there specific wads that close or open a pattern like this?

    thanks,
    Trail

    The short answer is no, not really. Not 'tighten.' Not in any predictable, repeatable and significant fashion anyhow.

    The several designs of 'Post' wads will open the pattern up a bit ... maybe a choke number ... number & ½?

    Have you thought abt practicing with ¾ or 7/8oz? Smaller shot charges reward better pointing.

    You can select your reloads with care, and achieve relatively more open or closed patterns according to Bob Brister's "Shotgunning the Art and the Science." For two loads with the same muzzle velocity, the one with the lower pressure will tend to have smaller patterns. For two loads that operate at the same pressure, the higher muzzle velocity load will tend to have a more open pattern.

    Bob K has it pretty much like what I have found. I load 17.5 gr 700X and I find that if I increase the load by 1/2 gr it opens up the pattern.

    Thanks, guys. So...I've been using the windjammer-style wads because I think the 8 peddle opens up and leaves the shot column a just bit quicker...slightly more open pattern. Sounds like this is not really valid....correct?

    I wondered the same thing. Used my standard 1 1/8oz 16yd load of 16.5 grains of 700x in either a STS or AA hull, W209 primer and either a CB AA clone or CB Windjammer clone. (Both published IMR loads). The Windjammer was noticably more open. Not a great amount but you could see it on the patterning board. There was a hotter core with the CB AA.

    Down Range Mfg. makes a post wad that will open up your pattern. Lots of sporting clays shooters use that wad when a more open pattern is desired.

    I have never used a "post wad" but the other wads mentioned will not change the pattern. Certainly, 1/2 gr won't change the pattern either, that is baloney. The reloader alone can vary the shells by .4 grains. + or -.2

    Trail, If you have a full choke just shoot it and forget about gimmicks.

    I use the Windjammer for extremely long shots as well as short or close shots, do not notice any difference, good breaks at any distance if I do my job.

    Some will argue about load combinations being the center of the reloading universe. I think a lot of this comes from rifle and handgun reloading. IMO, the choke does most of the work in determining your pattern. If you want tighter then you need a tighter choke.

    To follow up, in my patterning research with my guns, the effects of load components is secondary to what choke tube, or what fixed choke you select. I do feel like I get the best patterns with the TGT12S wad in my gun. But like I said, that is a MUCH smaller effect than say the difference between a Modified and a Full choke.

    Would you bet on a 2-cent wad or a $2500.00 (more or less) barrel?? Ask Neil Winston. I think he might go with the barrel and choke!........merlyn

    You can contact your reloading supplier and ask them if they sell any type of "long range" wads. These wads are designed for waterfowl hunters who reload thier own hunting loads. The wad fingers dont open so quickly, so the wad stays with the shot column longer. These wads usually have a heavier pay load like 1.25 oz. and higher, which in turn would not be cost effective when it comes to reloading for shooting trap. Though it wouldn't hurt to inquire.

    Spreader wads can work very well. Full story:
