I went to the range today to sight in my .45-70. I recently put a tasco pro point red dot scope on this rifle. I got it sighted in for elevation, and when I tried to adjust the windage, point of impact began to jump all over the place. I checked to see that the scope was still mounted securely, nothing seemed loose, but it still was all over the place. So I'm wondering if anyone has had similar experiences with a red dot scope and a rifle that recoils pretty stoutly.
