RE: 54Cal or 50Cal for Elk
Greets,
I personally own a caplock .50, but I bought mine as a deer gun that could take an elk if I ever wanted to. If you are buying this rifle specifically for elk, and assuming you going to use the more traditional bullets and loads, I would definately go for the .54. That cal can be used on deer or elk, or any other big game in my area, and its got more punch to it that a .50.
Just my uneducated opinion!
