    After a long day working on my deer stand, I decided to re check the drop on my hand loads. A few months ago I had some questionable calculations.

    I'm going to zero at 200 and click up/down from there.

    So I shoot at 100 and wind age is off 7 clicks. Shoot 200 and adjust 10 click. I then, by some miracle shoot my very best group by a large margin.

    Then I shoot at 300.....and I hit a group about 3" HIGH! It makes no sense to me! Maybe I was to jacked up from my previous group.

    I had a pellet rifle that kept gaining height..a bent barrel.
    another could be updraft from wind rolling on hills.
    awesome group you shot there..

    Have you ever done a "box" test with your scope to check that it is tracking properly with each click?

    I concur that it's scope issues.

    And good luck beating that group - I bet it's under 1/4MOA.

    Very nice group ! Id do a box test and make sure scope is tracing right also. And check and make sure your ring and base screws are tight.

    When everything is right it all comes together, clean the rifle and make no other changes and go shoot it again.
    Try to do everything the same as yesterday, usr the same load/ammo.

    Thanks! I'll try the box test and shoot again from 300 now that I'm zeroed at 200. I've tracked it in the past after mounting it to the new base and it seemed to respond well and is predictable at 100.

    Things were getting weird after that group with unexplainable shots. I'll take the advice and see what happens. I need to find a chrono so I can put a chart together.
