Thanks for your service, Marine! For deer hunting you can stay right where you are at with your longbow at #50 and be fine. Many, many guys and gals on here shoot that or less successfully. I used to shoot heavier weight bows, and there are advantages to it, in my opinion, but a bum shoulder has limited me. I shot a nice deer this Fall with a 53# River's Edge recurve that I just love. Stuck in the ground on the other side.
I like longer bows, even in recurves. Mine is 62" and I draw very close to 29". It is comfortable and very smooth to me.
If you get a chance before you order there is nothing better than shooting a lot of bows before you choose which one to buy. If there is a trad group in your area I'm sure you could shoot a number of different models to help you decide. If you can get to an archery show, it's even better.
Have fun, and welcome.
