    Validating turret ''click'' values

    Inspired by GWH and his post about how much the Weaver Super-Slam scopes actually move per ''click'' and past articles I've read that were written by Greg Duley I made up a pretty agricultural looking testing rig to find out for myself what that answer is?

    Here's a step by step guide on how you can do this at home or on the range if you so desired too.

    1) On the computer using excel, make up a spread sheet with say 25 rows and 2 columns.
    2) Select all, then right click to format cells. The choose size and make the hight of each cell 2.66cm (which is 1MOA at 100 yards).
    3) Number each row (do it bigger than I did as I could bearly read the numbers with my dodgy eye sight.
    4) I then printed this spread sheet and using tape stuck it to plywood (note more tape was used later on as the wind kept stuffing it up)

    5) Level it in all directions the best you can.

    6) Using a rangefinder set the distance between the scope turret and the ''target'' as close to 100y as humanly possible. (there will be a small error - but it wont matter as the error percentage is negligible).
    Now set up your rifle using what ever you have available. I used wooden wedges and a heavey sandbag on top...this worked okay, but required a very careful hand not to bump it. There will be much better ways to hold the rifle - but as I said it worked okay for this one off test.

    7) Dial away to your hearts content and see if the numbers on the grid match what you're doing with the scope.

    Luckily for me the two scopes I tested (both Weaver Super-slams 3-15x42sf) tested 100% for the click values up/down up to 25MOA all the way through the range.

    So cheers GWH for the motivation, great to know that my scope cannot be used as an excuse for me missing anymore, only my lack of experience and poor shooting can be blamed now.

    nice, good test must get around to doing it properly.

    Did you have a play with the horizontal adjustment? should be the same you would think

    I should have, but I thought it would be close enough as dialing for the wind isn't an exact science. If it was out by a little I figured it wouldn't really matter as the most I've ever dialled is 2 or 3 MOA. Even going off my charts 5.5MOA gets you on target in a 10mph crosswind at 1000y.
