High standard Duramatic shooting high

keywest
I was at the range today and my Duramatic that I recently bought was shooting approximately 6 to 7 inches high from point of aim . The sights are non ajustable and are not altered in any way that I can see . I tried Federal ,CCI , Remmington and PMC bullets and got the same results with all 4 brands. The windage was perfect on all 4 brands as well . Other than putting adjustable sights on the gun , is there something that a gunsmith can do to fix this ? Thank you in advance for any and all help .

    This is very common on .22 pistols with fixed sights. The only way to rectify this is to VERY CAREFULLY file down the rear sight. I have done this many times. Usually .025 to .035 has to be removed off the top of the rear sight so that it shoots to point of aim. Occasionally if more then .035 has to be removed, the notch in the rear sight has to be filed deeper. When this is done a needle file with "Safe" edges is used so that the width of the notch isn't altered.

    The above is correct (be careful [;)]) but 2 quick questions - are you using a center hold or six o clock hold? If you're using a center hold and hitting high switching to a six o'clock hold will lower your point of impact a few inches.

    Are you using high velocity or standard, 32 grain HPs or 40 grain solid? Different spec ammo may have a different point of impact, changing ammo & point of aim might get you there.

    I started at center hold until I saw where the bullets were hitting and then switched to a 6 o'clock hold which brought the group back into the center of the target . I thought of the idea that RUFE SNOW gave but I wasn't sure if that was the proper way to go, so I figured I would ask the pros for thier advise.I have a small file set which has the file recomended so I am going to file the slot a little deeper and see what happens next weekend . I was using 40 grain bullets from all 4 brands today. Thanks for the post guys !quote:Originally posted by dfletcher

    Those particular models, came in two barrel lengths. You might have a mix-n-match scenario, and have the taller rear sight with the shorter front sight.

    I believe in their hey day, they were an entry level bullseye gun, and designed around the standard velocity ammo, with the 40 grain solid bullet.

    Out of curiosity, how is it grouping? For the most part they were decent shooter's.

    The groups are very good with your everyday run of the mill ammo . At 20 yards it was shooting 1 to 1 1/2 inch groups shooting fairly fast. The gun itself is smooth as silk to shoot and I know it will be a lot more fun once I get it to hit where I'm aiming .quote:Originally posted by tsr1965

    There was only one rear sight for the Dura-Matic.

    High Standard pistols were manufactured for a 6 o'clock hole. See page 4 on this instruction sheet.

    Is the barrel properly seated in the frame? Is there a burr on the mating surfaces where the barrel and frame touch>

    Thanks for the link . Barrel was rock solid and no burrs at all. The gun shoots very good groups , they are just way high . These seem to be well made guns, I just wish they came with adjustable sights .

    You are shooting standard velocity ammo right?
