    I have been shooting a 90T for about 2 months and am now shooting it not bad.When Iam on the target nothing but dust.Last night wanted to try something different,so I set up my kids 682 for myself.Went to the shoot board and got the POI the same as the 90T.Went out and shot it and dont get the same breaks.No powder like the 90T.The 90 has factory full choke,and used Berreta optima full.Any ideas on why the difference in the breaks.

    The weight and balance of the guns are different. Even though the pattern board appeared to show the same POI as your 90T...that was on a stationary target. You apparently never got the meat of the pattern on the target.

    Definetly noticed the difference in the weight of guns and how they swing,but I thought if I was on the target should get the same breaks.

    Itchy',

    90T's are generally choked at about .040. They are very tightly choked from the factory. And to this, some of the barrel ID's are .755 from the factory. If you get a chance to Mic the barrel with a bore guage, do so. 90T's have allways been target smokers!

    pattern is more than a single choke dimension

    pattern the gun at shooting distance and then at 40 yards-- compare patterns to the way you shoot-- and go from there

    PS as mentioned above-- there are a lot of variables you are dealing with with two totally different guns

    1. Gun dynamics of weight and distribution of mass
    2. Fit
    3. Other things- trigger , lock time, etc
    4. POI
    5. Percentage of shot in the kill zone

    within each of the above there are sub variables

    bottom line- it is difficult to narrow in on one thing which causes you to shoot good or bad with so many variables

    plus you could just have a good day or bad--- ie your own variables- unrelated to the gun you are shooting

    regards from Iowa

    My guess is that the 90-T is getting more shot onto the target at the same time vs the Beretta due to a shorter shot string.

    Larger bore diameters generally produce a shorter shot string than smaller bore diameters, with all other things being equal.

    Some shotguns shoot to expected percentages, some need a good trading. Not all are created equal regardless of what the numbers say it should be either. Hap

    I am going to add one more thing here.I used to shoot a 3200,and with bottom barrel,imp mod, was getting better breaks than the Berreta full.Are the Berreta chokes open more even with a full?I like shooting the Berreta,but with the 90T getting those kind of breaks,it gets the confidence up.

    itchy,

    The other thing that I forgot to post, is that Beretta's are notorious for a very abrupt forcing cone. When I got rid of my 90T, I bought a 682X unsingle combo. My Beretta had Mobile chokes on both barrels. I invested in a set of Briley extended choke tubes and the quality of the "break" was improved. I then took my gun to a very good gunsmith and had the forcing cones lengthend. I then started to get the same quality of break that I experienced with my 90T. I know for some that the "lengthend forcing cones" is a no no, but it has worked for me on every gun that I had it done to.
