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.
