I got a quick question for y'all. I'm trying to decide on which firearm to get next. Cabela's sells a drop in barrel, etc. to convert an AR-15 style rifle to shoot the BMG. Here's the question: Are there any ethical problems with using the BMG on elk, moose, bear and the like? It won't be used on anything smaller such as deer except maybe a 'yote. I understand about being able to shoot it, the recoil and the like. Supposing I can handle it what are the ethical implications of using the .50?
