    I know that it has been discussed adnauseum, but help me understand something. On prior threads I have seen advise about checking POI from 13 yards. I don't think I care where my gun shoots at 13 yards, do I?

    At 27 yards, if I break a target 12-15 yards from the house, the shot is a 39-42 yard shot. What I really think I need to know is that at that range, my Guerini unsingle is shooting about 70/30, from an off-hand, natural position, not a bench rest.

    Am I on the right track here? Thanks, Dan

    Dan, the prupose of the bench and 13-15 yds. is a starting point to determine if your gun is shooting on horizontally and distance above or below POA.

    If you are centering targets from the 27yd.line, then I wouldn't worry about it. If it's not broke don't fix it. Steve

    It's also easier to check POI from 13 yards. If you are shooting 2" high at 13 yards, that's 6" high at 39 yards, and a 70/30 shooter. Want to try higher. Set your POI at 3" high at 13 yards. That's 9" high at 39 yards and an 80/20 shooter. What could be simpler?

    Dan,
    The reason they suggest using a bench rest is because alot of trap shooters do not shoot very well offhand. But if you are an experienced rifle marksman skilled in shooting offhand there is no problem doing it your way. HMB

    Along with all the above, It's pretty hard to accuratly identify the center of the pattern at longer ranges.

    Guys- Thanks for your respones. I was using the offhand method because I thought that it would more closely mimick how I shoot in terms of stacking the beads, or actual shooting conditions. Thanks.

    It does Dan, but it intoduces errors at long range.

    I do all my POI "testing" at short range. Certainly not more than 20 yards. I use a bench with a rest and aim while I'm trying to find out where the barrel shoots, and if it is correct. I stand and point at targets 13-15 yards away when i want to see where i shot the barrel. I only test one thing at a time. I draw vertical and horizontal lines on the paper. Then I stand in my normal stance, mount the gun and track a vertical line. After I pull the trigger, I look for left/right distances. When I'm done I do the same for horizontal lines checking for up/down differences.

    After that, I know where the barrel shoots, and where i shoot it, and can take it from there.

    Botton line.....If you KNOW your gun shoots 70/30 at 27 yds, you are OK if there is no windage problem. But you won't know for sure if you miss occassionally due to a windage problem. Shoot 13 yds benchrest to find out.

    Thanks, everyone- I understand better now. I will sight in from a bench at 13 yards tomorrow, observe the actual POI, and then based on that measurement, I can calculate what my POI would be at 39-42 yards, i.e.: if 4" high at 13 yds, then 12" at 39 yds, etc. From there, I can adjust my rib up or down to acheive my desired POI, such as 12-15" at handicap range. Thanks.
