Well I've encountered a frustrating problem w/ my new Savage 11 Long Range Hunter 308.I cannot get a decent group to establish a zero at 100 yds. I set this rifle up w/ the Bushnell 4200 Elite Tactical on Burris HD Tac rings w a / Picatinny rail. I carefully cleaned the barrel and then I got the rifle onto 4" paper at 50 yards w/ the cheap UMC Remington 'white box' ammo. I cleaned the barrel between every 3 shots and all seemed ok. Then I set up to get my zero at 100 yards w/ the Hornady 150grain Superformance and I was quite dismayed to see a really poor pattern. The groups are totally variable with any where from 1 to 4 MOA. I tried the UMC stuff just to see what it would do and the pattern was about the same. I'm more than willing to try some other ammo but this experience is very unlike anything I've ever experienced before with other rifles. The other rifle I bought to get into this long range thing is a Savage 22-250 heavy and I'm already out to 400 yards and well into developing a data card for it while the 308 is becoming a thorn in my side. Ive checked all my mounting hardware twice and find nothing there. Worse thing is now I have no confidence in the 308 setup so that's compounding the problem. I've gone thru trying to get it zeroed 2 times now. Any suggestions would be appreciated? PLEASE NOTE: After a very long, expensive(shell$) and frustrating process of trial & error I believe that I have determined that the Bushnell 4200 Tactical scope is faulty. I will now begin what what will probably become an even longer and more frustrating process of sending in this scope for 'replacement or repair'. Naturally I now have no faith in this scope and I will try and find some way to never put it or it's replacement back on this very excellent rifle.
