Got pellet on pellet at ten yds using the chairgun suggested aim point of +3.7 mil dots. Then went out to 20yds which should be 0.14 mil dots (which is only a gnat's off zero. Spot on! For about two shots, then suddenly dropped a couple of inches.
Reset the scope to hit 20 yds at zero. When I got several shots consistantly in the same hole, I brought the target forward to 10 yds and shot again at +3.7mil dots (as chairgun states). Pellet on pellet. So it seems chairgun works quite well.
The problem now is why did it do that sudden drop? Hope I haven't dropped on a scope that doesn't hold zero.
Bad pellet or inconsistent hold most likely.
