I know guys who wont shoot a grouse until it flushes because its "unsportsmanlike",Id rather take em on the ground and make a fast kill,i would also rather not miss out on a grouse because my "ethics" demanded that i wait for The bird to fly.I would rather shoot my deer broadside at 100 yards sleeping,but that rarely happens.I take whatever shot i think im capable of making given the situation,its completely based on my opinion of my capability's and the opportunity i have.I know my limits but Im always trying to expand them with practice and good equipment.I haven't lost a big game animal in my entire rifle hunting career,i know that's partially luck but I am still proud of the fact,knowing your limits is being sportsmanlike in my opinion,taking a shot you know has a slim chance of being on target isnt.I take more pride in that 100 yard shot I made offhand after crawling through the snow and prickly pear to close the distance than i do the 450 yard shot from my bipod after using a laser rangefinder to get my hold over,but Ill take either,Ill do whatever is necessary to have a successful hunt within my limits and the law.
