I shoot a MkII TR at 50y+ with a scope BR & prone. I shoot a 10/22 TD with iron sights, with and without a sling, standing, kneeling, sitting & prone, at 50’. I haven’t taken it outside yet. These aren’t the top of the line, absolute best, micrometer required for group size, .22lrs, but I have fun with them. What bolt repeater & semi auto air rifles would I be looking at to shoot the same? PCP? Large CO2? Any one here have a clue?
