[QUOTE="Jon A, post: 336961, member: 319"] Yikes!, my bad. In my haste to pull a quick number I had the **** thing set to G7 instead of G1. I knew those numbers didn’t seem right! Serves me right for being in such a hurry. Anyway, you’re right—about 11 inches. At 1500 you’re talking over 5 feet, so the point is still unchanged—a relatively small difference at 960 that could be covered by other errors becomes a blatantly large at 1500. Steve, you don’t need any super expensive scope or anything as long as it’s repeatable. Just measure the clicks. I suggest everybody do that no matter what scope they have anyway, but it’s especially important if you’re trying to use it as a tool to measure drop. You can lock the rifle down and go up and down a yardstick or similar at a known distance, or the easiest is to use a collimator. All manufacturers will have an acceptable +/- % range, some larger than others. That doesn’t even include scopes that are marked MOA but are really IPHY, and visa versa, etc. [/QUOTE]
