I recently picked up a Center Point Patriot 415 package. I was not satisfied with the scope that came with the package so I picked up a Killer Instinct Lumix Speed Ring 1.5-5x32. I wasn't happy with it either as the parallax was severe and it had focus issues as well. After much research on this site I decided to buy a Ravin take off scope from Wyvern.
I got the Ravin scope installed this morning and began the site in process. I got it dailed in at 50 yards using the turrets and then moved to 30 yards making adjustments using the speed ring. I had the Patriot shooting tight groups at 30 & 50 yards.I was extremely happy with the results and then I moved the target back to 60 yards and that's where the trouble started. My 60 yard POI moved about 8 inches to the left and 2 inches high. I did not adjust the turrets or the speed ring. I moved the target back to 50 to see how it would shoot using the center crosshairs. I shot a very tight group but it was 10 inches or so to the left and a little high. I checked the scope mounts for tightness and looked over the bow closely but nothing appeared out of order. I made the necessary adjustments with the turrets to get the POI back in the bullseye at 50 yards. It's shooting tight groups again at 50.
What in the world happened? I'm scratching my head over this. I really like this scope but I'm confused as to what happened.

Franklin, the Ravin’s center crosshairs are set to be sighted in at 50 yards with the 40, 30 & 20 yard dots above the center 50 yard crosshairs.
I’ve since shot about 25-30 more times with no change in point of impact. It’s still a mystery to me as to what happened earlier with the sudden shift in point of impact.

I found once I went past 50 I was having the same issue. I glued a small bubble level. man was I canting the bow badly. It didn't help that I wasn't on level ground either which accentuated it also

Everything is tight. It wasn’t like a loose mount were the arrows were scattered all over the target. It just suddenly started shooting tight groups 8-10 inches left if point if aim. I at first suspected loose mounts or bow tilt but I checked all mounts and am shooting out of a rest. I’m beginning to think that when I put the turret caps back on the scope it somehow turned the adjustment to the left. I’ve never had that happen before but it’s about all I can come up with. Bow is still shooting tight groups after readjustment. As a matter of fact, I’m sitting in a blind as I type this reply ...Hoping to get first kill with the Patriot this evening.

I have a r29 takeoff scope from there also. Mine works well, but it's not as straightforward to sight in as is described. I set mine at 50 then adjust the speed ring to get 20 dead on. Then check again at 50 and hit low. Readjust 50 then check 20. It's like 50 isn't center of the scope. If I speed up the speed ring the 50 poi drops. Reverse is true also. I always lightly bump the scope with the heel of my hand lightly so any stickiness of the crosshair springs will relax and take my turret adjustments. Something I learned to do with airgun scopes. I set and check mine now starting at 50 then 20 then 80. Then go back and forth from 80 and 20 setting my speed ring and turrets until both are perfect. Everything in between lands true once I do this procedure. Haven't tried farther.

Just remember that small height (speed) adjustments at 50 yards or more are barely effecting the 20 yard zero. It takes a lot of clicks at 20 yards to do what a few at 50 will do. Once you are dead on at 50 only use the speed ring to adjust the other settings. Leave the height turret alone.

The cross hairs were stuck in your scope. After adjusting tap on the scope before shooting. Ive had that happen numerous times. That is not a good scope. 329.00 list and you can find them for 50.00 I've had four fail. I like the reticle and speed ring but it is a cheap azz scope. Wait for it to get water in it or get blurry where you cant tell a deer from a cow when looking through it. It pisses me off that the come on a 3000.oo crossbow. :mad:Yet this year Ravin does it again. No change . Good Luck. If you have accuracy problems you know where to look. 29.00 should be the price IMO.

Part of problem is after you get it dialed at 50 yards, you need to go back to 20 yards not 30 yards with Ravin scopes and make adjustment with only speed dial at 20 yards. This would account for height being off. Being that far left could be having the scope not level when mounting it or canting it while shooting. As others have stated make sure your crossbow is level when sighting in your crossbow. Also use only one arrow thru out site in process as a different arrow may not shoot quite the same.

HunterB, I kind of suspected the cross hairs being stuck and then suddenly moving. That would make perfect sense.
In all my years of shooting scoped rifles I've never had that happen but I have heard of it. I did start tapping the scope lightly after each adjustment since then.
I've had no more issues with the scope and it and the bow are performing well. Other than that one glitch I'm satisfied with the scope. It's much better than the scope that came with the package and the Lumix I replaced it with. I'll have to keep an eye on the moisture and blurr issues you mentioned.
