Tikka 300 wsm help

[areyoujelen]

I have a hunting trip to New Zealand coming up. I just recently bought a tikka t3 lite in 300 wsm for the trip, and a future build I have been wanting to do for a while. I topped it with the nightforce nxs from gunwerks with the g7 reticle. Pretty much my dream set up minus a proof barrel, and a new stock. I hit a wall shooting the other day. Horrible groups out of multiple brands and weights of ammo. Then I had one lock up in the gun due to head spacing issues (never heard of or seen this from a tikka before). So I called tikka and I shipped the gun back to be fixed. They couldn't promise it would make it back in time, so I decided to order another, and sell one in my shop. The new one came in today and I was excited, until I started shooting. It would hold groups, but every time I adjusted the scope it seemed to go haywire. I would fire a few shots, and it would start grouping. I could adjust for .50 moa and it might move 2. Just like the first I tried with different Ammo and weights. I shot from a rest, bipod, and a lead sled, all with the same results. Everything on the gun is tight and in level. I have never experienced anything like this, and was curious as to if anyone could point me in the right direction.

I would try a different scope, you might of got a lemon, doubtful but a possibility. Have you tried shooting it without the lead sled?

why do you think it has anything to do with the rifle and not the scope?

predator I have tried shooting from bags and bipod also. I didn't get around to trying another scope today,but I will give it a try tomorrow. Gray wolf I wasn't dismissing that it might be the scope I was just hoping it wasn't. It just baffled me how speraticly it was shooting. I have had a few lemons for scopes, but nothing like this, if it is the scope.
