    l just got a Beretta A391 Xtrema 2 and it shots high. Holding just under or on the target it shoots about 1 1/2 foot high. What could l do to lower the impact area. Bigger front bead?

    Say you went from typical (for Bradley beads) of 1/8 inch (that's 4/32) and the largest one in the Brownell's catalog, 5/32, you will get a gun that shoots about an inch lower - if you aim with that kind of accuracy, that is, one inch. If you aim with less accuracy than that, you'll never notice the difference.

    If the Beretta one is .1 and you put on 5/34, count on a change of about five or so inches.

    But it's rare for the barrel of a Beretta of any kind to shoot high by itself, hgpr. And that high is unheard of. Are you sure it shoots high at all - that is, have you tested it on paper off a rest? Several shots? Up close?

    If it does pass the high-shooting test, next is to ask "Why?" Do you see a lot of rib? If so, you can sand down the comb. If used, did someone bend it up? (Ask someone at the club who knows how to "read the rings." If it has been bent up- and it's easy to tell once you know how - you can just bend it back down.

    I doubt changing the front bead will make much of a change. The way to make it shoot differently is:

    1. Find out where it shoots

    2. Determine what is making it shoot there

    3. Change what is making it shoot there if you want - in the direction you want, and to the degree you want, and all that. But you will never know where to and how much until you know what it's doing now and why.

    One way to find a bend in a barrel, is take the barrel by it's self using a the edge of a window, looking through the barrel align the edge of the window edge of the window in the center of the barrel, the line formed in the barrel should run straight to your eye. So holding the barrel on it's side and see what the shadow(?) tells you.

    call Todd at Poly Choke and order a reverse rib .300 in front and .100 in rear. Glue it on and your problems are solved for life. I have several and they are the cats meow. I hate high shooting guns too
