I'm looking into a good rifle soon, something I can reliably hunt deer with and count on in a shtf situation. Preferred a semi auto, but I'm open to bolt/lever action. What do you guys think do I take on a project mosin? What's a good anti-deer caliber for shtf? I'm new to rifles so I'm ready for all opinions and general info. Me personally I have a budget of $400. I like the idea of a project rifle. Something I can make mine. Thanks all.
