And you've totally missed the point again by referring to performance,
Do you test & compare your cheap no-name mounts with those of better brands ?
My point with the pellets is that we don't buy cheap purely because they're cheap, regardless of how they shoot, but that seems to be exactly what you are saying about the mounts buy cheap for the sake of it
I have tested different mounts because when fitted to a rimfire rifle those errors between POI at 20yds & POI at 150yds can be lateral movement of 2" or more.
