My mkii will out shoot my rpr all day long. Only upgrade is boyds stock and bottom metal. Use an athlon midas tac on it. Favorite rimfire rifle by far.
I have a 10' x 10' platform 11' high. Used 16' 6x6 posts, one in each corner. Can easily accomidate 3 shooters. It was very wobbly until i added 2x6 cross members from ground level to platform, one on each side. Very happy with it.
Savage mkii all day long. I have two, one stock and one in a boyds evolution stock. Both shoot one hole at 50 yards, but the stock stock is not very nice to use. Norma tac-22 is their favorite round and not too expensive. This is what i would have bought if it was available at the time...
