My first Tikka, 223 Varmint, shoots like a champ and uses the factory rings. My second Tikka, 308 lite.....nothing but problems. I sent it back to Beretta last Dec 11th and it got back in mid May. They had to fit a new stock and accuracy test it, only took 6 months? I shot it when it came back, still shot like a dog. 6 months waiting for nothing until..........
I bought a set of the Talley lightweight rings which screw directly onto the top of the receiver. What a difference!!!!! These rings are $40 a set and I think, well worth it. Talley Lightweight Aluminum 1" Scopemount ,SKU: 930714 from SWFA. My last 3 shot group was .8" with the Talleys. With the factory rings it was between 2-3". My only problem was that there are the little screws in the top of the receiver. They turn OK and start to come out, then they just turn. With trepidation I had to drill them out, thankfully all was good and no threads were damaged. I actually have a Simmons AETEC 2.8/10 on the rifle which is a great scope. I took it off my 17HMR which now has the 4.5/14 AETEC. That scope spent a year on my HMR and did a lot of hunting, sliding down steep hills etc and never lost zero. A great feature is the fact that eye relief remains constant at all magnification and is around 3.5" ideal for the 308. Anyone looking for a good quality, bullet proof scope for under $200 should look no further, not at all like the old Simmons Walmart scopes. At last, the 308 is fixed and I have a lightweight, accurate and reliable deer rifle.
