Don, I agree that Lyman's Target Spots and Super Target Spots are nice, old technology, scopes, but they don't have much in the way of field of view or light transmission when compared to today's 10x scopes, even the inexpensive Bushnell 3200 10x40s. The TS and STS were top-shelf in their day, but they are anachronisms in light of the advances in optics technology over the past fifty years. Or so it seems to me.

PS - the only old technology variable target scope that I recall seeing anybody use are the B&L Balvar 6-24x stove pipes.
