Great scope, but had trouble. - Nikon ProStaff Rimfire 3-9x40mm Rifle Scope, Matte w/ BDC 150 Reticle

So here's the deal- I have a marlin model 60sb (tube fed bull barrel .22 semi-auto). The rear sight on this rifle folds down supposedly to accommodate the bell on the forward end of a scope that comes down there when mounted on the rifle. And it does. I had an old 3-9 scope made by western field in the 60's, and I used the basic Weaver 1" .22 tip-off scope rings from wallie world and they mounted it up just fine. When I switched to the Nikon prostaff 3-9 rimfire, the bell where the scope gathers light (the end towards the muzzle) was too large to mount properly with the basic .22 tip off scope rings from walmart. It hit against the rear sight ramp of the rifle, and wouldn't sit all the way into the rings because of it. I need to get a taller set of rings for the rifle, and it should work great! I also wanted to test out the scope now with the rings i had, so i put it on my sister's little .22 and took it to the range. It's great! It was wayy off but I zeroed it. Then i was busting grapes at 70 yards. But the best part is, I took it and did a box drill. I shot a 3 shot group through the bull's eye on a target at 50 yards. I moved the turret 16 clicks to the right, and the next round was exactly 4 inches right. Then i clicked 16 clicks down, and the round was 4 over and 4 down (or 5.6568 inches at a 45 degree angle- pythagorean theorum haha). Then, I clicked 16 clicks to the left, and it was 4 inches below the bulls eye. after 16 clicks up, it was back in the bulls eye. The turrets do what they say they do. AND when you have your rifle zeroed, you can pull the turrets up and rotate them without moving anything and put them back down so that the zero marking is on the line. That way, later you can move your turrets and bring them back to your true zero. Great scope!
Pros: everything. accuracy. repeatability. reliability.
Cons: none
