I mostly agree with Taylor. 50 beo would not be my first choice either. Something in 308 would be my choice. Good range and will kill anything you would ever want to eat. Easy to find ammo for. 7.62x39 would be my second choice, 223 my 3rd. I like the 50 beo but it just does not have the utility that other rounds do.
I do love pelican cases though and recommend them highly. Molle vests and backpacks are nice. I'm more careful about what I put on my backpack as its is easier to swipe but light things that dont offer much interest are fine.
