.45-70 is my round of choice. Not a whole lot of range, but the 375 grain hard cast slug at 2300 fps I use has never not put one down within 50’ of where I hit it. Just a big red cloud behind it and that’s all she wrote. I see people hunting them with 5.56 rounds and just shake my head, I’d rather use something that’s an overkill to something that’s merely adequate myself.
Hunting these critters in Missouri is discouraged by the Missouri Department of Conservation.
The agency says shooting one just spreads the pack. It’s better to trap entire families and MDC will do it for free.
