I have been doing some searching and cannot find a riflescope more powerful than 40x. Does anyone know of any more powerful? How did the Canadian sniper hit his target at over a mile with a (40x +/- ?) scope, even with several shots?! I use a 10-40x50 Osprey International (and I love it!) on a .308 at a life size steel sheep target at 550-600 yds. and it is hard to place a heart/lung kill shot. So how do the snipers hit man size targets with surgical precision at greater distances? I know that my 43 year old eyes have recently changed (for the worse!) but Damn!
