Did not experience this with my old scope not changed mounts same as they were before in same place. what would be the reason for this is the big nikko elevation adjustment smaller than my previous targetmaster or something else thanks.
Yes looks like adjustments are smaller, and I bet you are at the end of travel too. Way to get round this is to get busy making and fitting plastic shims under one end or the other to slightly tilt the scope, the optimum being zero is in the center of travel both elevation and windage. Personally i use slivers of Nom yoghurt pots but other slivers of plastic can be used.
