number of years ago at an offhand Schuetzen match, I could not tell if I'd shot a double on a 200yd target with a 15-45x B&L Elite, so, I shot one more,cost me 25pts, I'd shot a double (.30 cal). Took the target with me to the store, set up everything they had there--ended up buying a Kowa 20-60x 77mm after looking at that target at 200yds pasted to the frt post of a Cdn Tire store. If you are going to spend the money on a spotting scope,you only need to buy it once--get at least a 70mm lens. Then you never have to worry about it again.
