HI, Kurt.. first of all. Thank you for your service, God Bless.
Bear Montana is a good bow. And a good choice for starting out. I would start out with 45# personally, But as an experienced archer you’re probably ok at 50# anyway,
There are many on here who can tell you more than I can. Just a couple of things though:
Get a couple of books: 1) Byron Ferguson;s, “Become The Arrow:, and 2) Brian Sorrell’s, A Beginner’s Guide to Traditional Archery. 3) Jay Kidwell’s, “Instinctive Archery Insights” another helpful guide as well,
Most importantly – Have Fun!
