I have one at each end of the $$ and power spectrum.
The first is an iron sighted Glenfield Model 10 22LR. The only modification is a strip of paper between the barrel and forearm. I learned to shoot with this gun in the early 70s. It will consistently hit match heads at 50 yards. Nothing fancy but it sure is accurate. My 12yr old son loves it.
The second is a factory stock Weatherby Mark V Stainless in 30-378 wearing a Leupold 50mm VX-III 4.5-14 with a German #4 reticule. With a Barnes 165gr X bullet loaded over a CCI LR Magnum primer and 107.0gr of Hogden H1000x it will group under 1moa out beyond 400yd.
