Ruger .270. Killed all of my deer with it in (other than Illinois) and have only lost one which I years later am still unsure I hit. Started using that Federal Priemium Vital Shock in the 150 grain a few years ago, loved it. Saw the effect it had on a couple of my buddy's deer in his 30-06 and switched to it. My deer have since been either dropping in their tracks or leaving me with a short blood trail that looks like a garden hose with red water.
