LaOtto222: I have the same Bushnell Banner with the bullet drop compensation dial. It never worked with the guns I had at the time.
The first of the newer types I got was the BSA Sweet-17 that I put on my H&R .17HMR. Works very well, I can hit a 4" clay target at 300 yards easy with it.
Then I got the Night Force, and learned how to set up the chart and how to dial it in for different ranges. That is what I used three weeks ago to shoot the Grizzly at 567 yards.
Then I got the scope from Cabela's that has the large turrets that are set up for different calibers, bullet weights, at set velocities. I have to say it took some getting used to, and it requires a range finder to be dead on. Also it will not let you change you loads once you have it set up, without totally starting over from scratch. But the one I have on my .223 Ultra is great and I do love it now that I have gotten used to it and shoot it well. I can hit a Red Fox anywhere from 20 to 300 yards.
