On my Savage axis 22-250 I have a Redfield Revenge scope(6x18x44). I had it sighted in at 1.5 inches high at 100 yards. Should be darn close to spot on at 200yards. Once I sighted it in, I re-installed my bore sighter just to document where the cross hairs are for future reference( in case the scope/gun takes a jar and I suspect the scope is out).
Today I set a china plate (7 inches round) on the side of an old barn exactly 115 yards away. I aimed about 1 inch up from the bottom and could not hit the plate with 4 shots! I installed my bi-pod and tried a couple more shots and "nada". I thought "what the heck"??? I drove back to the barn and my shots were exacly where I was aiming, but about 2 inches to the left. At 115 yards I thought for sure the shots would be close to 1.3 inches high hitting dead center.
What could have happened? I checked my scope rings and rail and everything is tight. Should a guy re-adjust the turrets? If so I would have to go a long ways up and at 1/8" increments, thats alot. Now I know "why" when I shot at a coyote yesterday at 180yards, I missed him.
It really absolutely sucks to not have a good range close by. If we did, I would spend a good day there!!
 
What about the wind? either when you sighted it in or when shooting at the barn? the coyote doesn't count, it easy to miss those guys, I've done it lots of times.

Was the ammo you used the same as when sighted it in?

The other question is, was your group tight or were they scattered? If you got a good group, say an inch, I would readjust it.
 
They put those twisty turny things on the scope for reason. Any pressure on the stock while sighting it could cause the scope to be out slightly the next time you shoot it. As Varmint mentioned different ammo or even a different lot # or the same ammo can change POI. Sighting in 1.5" high and assuming it should be right on at 200 yards doesn't aways work, you have it actually shoot that distance to be sure of that. The difference from your 100 yard sight in, and 115 yard target really doesn't even warrent hold off on a 7 inch target.
 
What happens a lot is a guy gets a rifle warmed up sighting it in, then comes back to find out his cold gun shoots to a considerably POI.

Some barrels have to be sighted in dead cold, and some for the first shot.
 
Only time I've had this issue is from sighting in with different ambient temperature or wind present when sighted in and not accounted for and then the drifted POI "strangely" shows itself when there is actually no wind.
 
We used to shoot up at the Batchelor shooting range before they took it all down.
Same rifle and same ammo at the Heffley range would need to be set up again.
Heat waves is what I blamed it on up at Batchelor.
This has happened to me/us too many times to be a coincedent.
 
We had about the same wind yesterday as the day I sighted in (6km/hr). As for the ammo, I used the same as when I sighted it in and they were reloads. The group on the barn were about 1" wide and about 2.5 inches tall. Not very good at all at 115yards. Reason I held at the bottom of the plate was: When I sighted in, my shots were dead center and 1.5 inches high at 100 yards. The plate was 115 yards so I thought I would nail it on the center holding low.
What I really need is: A really good range with a shooting bench/table and bags. Not this: Shooting from the back of my truck. When I sighted in, I layed in the box of my truck and used a " sight vise". Wasn`t overall comfortable. Can`t lay on the ground at all, the woodticks are horendous this year.
 
Was watching a youtube video explaining Parralax Adjustment. They say you can be off quite a bit if not adjusted properly. I just checked and I had mine set at 170 yards and had the power all the way up to 18. Hmmmm wonder if this was my issue? What do you guys think?
I`m a noob to this scope. My old Bushnell 3x9x40 never had this adjustment.

Yes, you're bang on, a good shooting position is crucial when trying to get good groups or even to find out what your rifle is capable of.

As for the ticks, I'm wondering where In Canada I can move to be clear of them. I think the to that is 'nowhere'. We've only had ticks here for about 4 years so they are new to me. I have 2 retrievers and it's a nightly chore to de tick them. We were eating supper the other night and my wife saw one climbing up the wall in the dinning room!

What about the paralax adjustment?

I'm no expert when it comes to parallax. What I do know is that shooting position must be good to minimize it, scope manufacturers usually set it to be right at about 100 yds and it's more of an issue at long distances.

Read the manufacturers instructions and set the scope up properly.
 
Are you playing with the magnification? Did you have the action out of the stock? Are the stock screws tight? I think this site should have a dedicated firearms therapist....
