Interested in thoughts about bullets that "do it all" in SHTF and survval situations. Outside of 22LR, most of what I have set back is in 5.56 and 7.62 FMJ military ammunition since it can be had in quantity at decent prices. I also reload and have a lot of brass, etc. for those primary (for me) cartridges. What would be the best bullet designs for defense, including against barriers and body armor, but would still be very effective for hunting? Naturally they would need a profile that would be reliable in a semi automatic. Remember that we are not bound by the various treaties that restrict our military. For 5.56 it looks like 77 grain SMK's might be the best answer, but don't know how well they would do for larger game. When we get to 7.62 it's much more open and where I'm mostly interested. Something like a Nosler Partition, an A-Frame, Grand Slam, or a Barnes X would clearly outshine an FMJ for game or assailants without body armor, but would their expansion make them less effective against body armor or barriers? Obviously bullets just don't bounce off armor and at the minimum getting hit by just about anything would cause broken ribs, etc., and put an attacker out of action at least temporarily, but when I'm defending my loved ones I prefer a lethal outcome so I don't have to do it all over again. My current plan is color coded mags for game optimized ammunition with everything else being FMJ's and that may be the best way to go, but still I think aout a "do it all and do it well" solution. Thoughts?
