Our NTxR League just held a 22 long range match that went out to 350 yards. I run a custom built 10/22 with all KIDD parts besides the bolt and receiver is still Ruger in a titan stock. Run a 20MOA EGW rail, Vortex 5-25 Viper Gen2, in Seekins rings. There was a lot of great guns out there and I was tied for 1st until the final stage (350 yards). I ran out of elevation and had to hold 3.9 Mils in my reticle.
So a 30MOA rail would give me plenty of travel for that distance, which I’ll get if we continue to hold the long range matches.
This is my setup, there were a lot of nice bolt guns out there but my gun seemed to hang pretty well.
