Nightforce br 12-42 unsteady POI [reticle]

[Bluto65]

I was bench rest shooting for groups at 200 yds with a 6.5 x 284. 1st group was three in one hole next shots were 3 at 6 oclok, 7 oclok and 8 oclok all at1/2 inch from POA. This happened successivel for 8 target dots with two others at 3 shots in one hole. The spread shots were about the same on other targets at 12 oclok 1 oclok and 2oclok. Absolutely no wind at 8am sun at my back. Temp was 65 deg. Reticle was NP2DD. I use a randolph rest which is very stesdy. Does anyone have any opinions about maybe the reticle having movement?

Parallax not adjusted properly?

My first guess is Parallax adjustment. Did you Move your head up and down or left and right to see that the crosshair stays on the POA. The second guess is that even though you think it is calm, there is stuff going on. You just can't see it. Sometimes this is the worst time to shoot. Matt

I went through a very similar experience just last fall. Long story short: I contacted Nightforce customer service. The fella I spoke was convinced that due to the weight of the 12x42 scope and the recoil of the rifle I was experiencing movement within my mounting system. He suspected it was the one piece rail. Upon his recommendation, I glued the rail to my action. The results were astounding! No more shifts in poi. The customer service fella said he would be more than happy to examine my scope should I wish to send it to him. He told me he gets many calls with this same complaint, but usually gluing the bases does the trick. It certainly did in my case. Just sayin!

This was my first thought also.

Could also be due to it being a 6.5-284. I had a hard time tuning the ones I built and will never build another one. One day they look good and the next I want to make it a tomato stake. Matt

My first thought would also be parallax. Then the mount. Pull the scope and check the screws. If they are not secure that's it. I use Loctite™ in the mounting screws. I did not see you mention the type of rifle. If it is a Savage make sure the correct rail screw (shortest) is in the front (muzzle). it would be nice if after this and you still have the problem to borrow another scope (anything) and if it still the problem. Maybe i have been lucky but in a lot of years I've only owned one defective scope.

Just read dkhunt14's reply. I too am a FORMER 6.5-284 owner....could not take it anymore and it became a 6.5BR
