SaltyDog, I wasn't recommending fixed 10's, but rather making the point that 10x is plenty of magnification to shoot effectively to 1000 and dollar for dollar a 10x40 optic will be better quality than a 20x50 optic. I understand also the low light thing, within reason. Europeans love their monster Hubbles because hunting for them is sitting on their asses in a stand in the middle of the night shooting pigs. Americans are a sucker for doing what the Euros do, so we have bought into the European idea that a riflescope needs a 50+mm objective. A Leupold vx3 2.5-8x36 will get you within ten minutes of a Swarovski 4-12x50 and do it at one quarter the cost. If you have the money to buy those few extra minutes, and don't mind being a pack mule, then the large objective, high power, spendy glass is certainly one way to approach the shooting game.
