EW,
Funny you should ask! This weekend I took my son's 308 to the range to put a new scope oon it - A Bushell Banner w/ a mil-dot recticle.
My past experience with the Banner line of scope was: I'm a member of a rimfire rifle team and about 1/2 of the participants use these Banner scopes with great success! My son, also a member, bought this Banner thinking It would do well on a CF silhouette rifle. I had quite a few problems getting it sighted-in and the groups looked like something JM mentioned - The POI flipped back and forth with each sucessive recoil.
Now...I not entirely convinced yet its the scope. Found a problem with the rings and the front base, a bad box of shells and the rifle was quite dirty. So I'm going back this next weekend to try again with these other 3 possible problems sovled.
Ray,
I spent a BUNCH of time at the reloading bench and at the range, trying to figure out why my groups were jumping back n' forth between two POI's. It wasn't until an old-timer at the range took pity on me and asked what I was so frustrated about that I learned it was the scope. When I told him what was driving me nuts, he brought his spotting scope over, took a look at my target, and sort of shook his head. Just when I thought he wasn't going to say anything at all, he looked at me and muttered, "Son...you get that scope fixed and you might just be surprised at how good that gun's shootin'." He rarely said so many words at one time in the years I knew him, but I learned to pay attention to every one of them.
His name was Ed and he was the first person I ever knew who really understood what it took to build and shoot accurate loads. His targets were 1 cent stamps, stuck 12 to a page on 8.5" x 11" paper. It was a very rare thing for one of his groups to even touch the EDGE of one of those stamps! I had no idea what a 6mm PPC was, but he sure did! His lessons about proper bench-rest shooting form saw me go from 1.25" groups that made me very happy, down to my personal best of .585", with a Model 70 Ranger in .270 Winchester. And that was when I still convinced it wasn't a group unless it was 5 shots.
I wish my eyes were still up to that kind of shooting.
If I were you, I wouldn't burn up a whole lot more ammo with that scope...shoot 10 rounds, no more than 1 per minute without changing your scope settings or point-of-aim. If you get that split group again (mine went from 10 o-clock to 4 o-clock, about 2" apart) don't waste any more time, just send it to Bushnell and they'll fix it or replace it, no questions asked.
