    First off let me start by saying we make alot of HMS shot for our personal use and for sale/trade. The number ONE thing every shooter says is "How does it pattern?" or "I would use it for practice but never competition". I have yet to see any one of the HMS makers post up good pics of product and results. So here you guys go take a look and put your .02 cents in there.
    Here we have the Remington shell factory shot cut open and pics taken..Note how they have crushed or cut some of the bb's.

    Now here we have our HMS shot, note it is NOT perfect.

    We also are using Jims better shot maker with the 7.5 drippers, We took a 1 oz reload with factory bought shot and opened it up and counted the bb's and took one of our HMS and did same thing. Results were.
    Factory shot 366
    HMS shot 385

    Apparently these are slightly smaller but by comparison they are very close.

    **all shots fired from 30 yards with a full choke same gun and a 20"circle drawn around bulk of hit.
    Here is the first pattern board shot with a factory load 1 oz remington

    This is a HMS 1 oz load
    <img src=http://i147.photobucket.com/albums/r320/himark900/IMG_1489-1.jpg>
    Here is shot 2 same HMS as above.
    <img src=http://i147.photobucket.com/albums/r320/himark900/IMG_1488-1.jpg>


    I just thought this info would be nice to get out there to all the non-believers in the HMS.

    himark- Your shot looks fine and I don't have a problem with your conclusion, but I would like to see some pattern numbers. I like numbers. I do have some problem with your 20 inch circle drawn around the "bulk" of the shot. In the first pattern (factory shell) if the circle was moved down a couple of inches, it appears as if the number of shot in the circle would increase. It is very difficult to determine the center of a pattern.

    The voids near the edges of the circle also seem to me to be a strong argument for using 1 1/8 oz loads.

    Pat,

    "The voids near the edges of the circle also seem to me a strong argument for using 1 1/8 loads."

    Why would the extra 1/8 oz of shot have an affinity for the edges of the circle as opposed to distributing themselves like the other 1oz? We're talking 40+ pellets in 7.5 or 50+ pellets in #8. Wouldn't it be better for him to use a more open choke AND 1-1/8oz shot?

    It just seems to me it would be more important to put the middle of the 20" cluster of shot on top of the 3 1/4" orange clay thing. And from the looks of those patterns either should do nicely IF you do that.

    It appears that the HMS shot has more density in the "Hot Spot" than the Remington shot at least from the shells that were shot ... Shot shells and patterns are like snow flakes, no two are alike ... WPT ... (YAC) ...

    Many years ago I hired a physicist who had worked for Remington on shot shells.

    He told me that the ballistic coefficient between true spheres and flattened, teardrop etc. shapes was negligible at the velocities and distances we used and would have insignificant effect on patterns.

    Perhaps not unlike the golf ball dimple syndrome.

    By coincidence, I directed a research program on Golf Ball dimples in a subsonic wind tunnel about 25 years ago. It was all lift to drag ratio at different velosity and rotation.

    I agree with the comments on moving the circle down a couple inches. We started drawing it and realized it afterwords. None the less it represents a idea of what the pattern actually looks like and it truely is non different than the factory load. Maybe you guys are right and will do some further yardage and post those results.
