I live in Sask, canada and to answer your question no I have not hunt a swamp in the south. However I have hunted in a lot of swampy & rough terrain. I know full well what it takes to get animals (larger then deer often) out of these god forsaken places and reason for wanting to limit the scamper in such an area. I followed up the above question with a couple more thoughts, just wondering where the poster or others for that matter lay in terms of needing such a shot. Seems to me the media and such glorifies such a shot, which I don't agree with. JMO but if i need it and the situation to the shot are favorable I will take it. However if not I'l deflate the lungs everytime and if possible hit a wheel on the way out!
