Im happy we could help with the decision to buy an NS522.
WIN333 eh?
I cant recall how they shot in my example, but based on price Im happy for you that they shoot as well as they do. Are you using an Elite scope or a Banner?
Thank you again, my other rifle is a TOZ-78-01 great gun but a bit uncomfortable to shot scoped in bench rest,
that's why I bought the NS522, fits in the caldwell front support like a glove.

The scope is the old plain banner nothing fancy but fits the bill.
I would like to try a Weaver T-Series 36x or the 24x ...in the NS522 someone did it ???
About the ammo i tried CCI std velocity and the Winchester 222,333 and cannot tell the difference. I didnt tried others yet.....
The only problem with the Winchester 222,333 is the feeding, i find may be is the bullet's shape 1 in 10 get stuck
