I shoot every two weeks. I'm shooting a 270. I will usually set my stock on a bag with towels and my butt on a remington butt pad. I shoot ok, but not consistent. I notice if I shoulder my stock and hold my sling down under the rifle it seem to be more stable. I see a lot of guys that don't even hold the stock or sling just shoulder the the butt and use just one arm to fire. I get tired of having to hold my rifle down like cement to keep it stable. Would a bipod help me to just shoulder my rifle and keep my left arm free?
