When some fool posts a thread about how his super modern muzzle loader shoots best with 400 grains of Whupbutt powder and a Tighty whitey plastic lucite tipped elephant skinner bullet. I call him on it. It is unsafe and will lead some newbie to do likewise because "Joe" did it. And whatever you read on the internet must be true. And then we see pictures of splintered gun barrels and mangled appendages. Lincoln narrowly escaped being injured or killed when a heavy duty cannon made for the US troops blew to pieces. A cannon made by people who knew what they were doing blew up during a demonstration for big whigs. Sorry but grabbing a piece of pipe of unknown quality, alloy, and history out of a junk pile and fashioning a plug for it, doesn't qualify as a cannon. It could be monel for all we know. Heck, my T=post driver is made with heavy wall pipe and a thick hardened steel plug welded in, guess it is a cannon. NOT!
