I keep hearing about the .450 Nitro version. It is not an option that I see on their website no matter how hard I look...... I know I am in dire need of viagra and arch supports, but do I also need glasses? Seriously though, am I just not looking in the right place?

To rechamber a .45-70 into a .450 Nitro is possible I suppose if there is enough barrel/chamber metal, but a factory chambering would b by far my 1st choice.....
