When I had a 9.3 double I kept the shot short (under 100m); but now Im considering a Ruger No1 in 9.3x74r with a low power optic. What kind of effective ranges can I expect to use it. Is 300m reasonable? I really dont plan of shots that far. Just wondering if its a good idea to stretch it that far if the shot presents. If 300m is asking too much, how far should I expect?
