Mount scope, take to range, sight in and I'm golden however, nothing ever seems to work that easy. Done went through a bunch of shells trying to figure this out now back to square one. This will get fixed this week or I'll simply put my old scope rings and base back on and work with it till the off season (end of March) it just seems wierd. the logic behind these impacts makes no sense to me. Thank's, Brad
I know how you feel man, sometimes it just makes you nuts when things make no sense.

I wouldn't discount the possibility of something being wrong with the scope itself. If the mounts are not really screwed up, that's the likely cause especially since you are still shooting well, just not getting logical or consistent adjustments.

Get it checked and remounted then get to the range. If it's still all over the place, well... . Time to Call NF.

Re: Problem sighting in scope Help please.

Brad: Id also suggest you remove it and start all over again. Im not a big believer in lapping scope rings...and I wont go into all the details though..at least not here.

Get the top half of the rings OFF and make sure the ring is tight; clean...etc...etc. Top half clean also...etc.

Lay the scope in the bottom half of the rings ONLY and very gently slide it fwd and aft...basically with little or almost no pressure on it. If it slides....your good to go.

Lay the top half on them and start a proper tightening sequence and if you dont have one of those ounce inches torque screwdrivers...then use the torx wrench that came with the rings and only gasp the short end of it.

Make sure reticule is lined up and square and tighten down ( and it dont take much) using ONLY the short end of the little wrench....NOW go to the range

At FIFTY yards set up a target with a night big RED dot ( I cant see the black ones for crap). With the rifle sandbagged remove the bolt and BORE SIGHT the rifle. Re-insert the bolt and fire ONE ROUND. Do this at 50 yards...its lots easier to see holes at 50 yds. Its also helpful if you know the published trajectory of your load... You know...1" hi at 50 yds makes you 1.5 inches high at 100 yds...also 2.5" high at 200...etc.

Once you get it shooting where its suppose to at 50...then back off and try it at 100 and 200...etc

Where did it hit? Move the reticule to that hole. Dont matter if you move it 1 click or 20 clicks...you got to have that cross hair on that bullet hole.

Fire a second round. Did it hit where you aimed? If not..do it all over again..even if you have to re-bore sight ( this time on that hole..not the bullseye) and go at it again.

It will coem around for you

Re: Problem sighting in scope Help please.

Sully, Thank's for your advice. I did notice that when I tried to adjust eye relief and verticle while in the rings but with screws loose that the scope didn't want to adjust easily( that may be part of the problem. I bore sighted as you described at 50 yds but did not shoot at 50 and first shot at 100yds put me on paper 7 cliks high and 9 cliks left. I adjusted 9 cliks right and shoot . Impact still 7 cliks high right above bullseye (perfect). Adjusted 1 click down, this is where things went south ( looking to hit 1.3moa high at 100yds) but impact is 2 cliks down and 3 cliks right. Shoot another shot to confirm and I get 2 bullets and 1 hole. I'm thinking ok let's try this agin. Adjust 3 cliks left and shoot. Impact is7clicks left and 2 cliks high. Now getting mad. Adjust 4 cliks right and shoot but, impacts 9 clicks right and 1 click high. Last adjustment5 clicks left and 2 cliks down and shoot, impact is 6 clicks left and 5 cliks down.

Frustrated with out making any adjustments moved to a diffrent target on same sheet and fire 4 shots I get all 4 in .7 moa. I'll get this mounted professionally then back to the range. Then we'll see.
