Well one winter day during muzzleloader deer season (December) I was in my marsh stalking down a nice track. I suddenly heard the ground CRACK under me and realized I was further south then I thought and this nice clear path I was following was my creek. Well needless to say, I went through, and fell over onto my side. And my rifle and I went under the water. It was a .54 caliber T/C Renegade loaded with black powder and a patched ball. There was a RWS 1075 primer on the nipple.
After I looked around to make sure no one saw my wonderful flop, I stood up and poured the water out of the barrel and headed to the house for dry clothes.
At my range, I figured ... what the heck. C0cked the Renegade aimed at my steel trap and BOOM!! that thing went off just fine. I was kind of impressed with the rifle. Not my swimming lesson but how water proof that rifle actually was.
