I reload everything I have and primers are what are hard to come by. Have plenty of brass I have picked up over the last several years. You can still find bullets, mostly premium, but still can find fmj bullets. Power is not to bad, and with multiple brands can be swapped or substituted. Primers are the key, and hardly any to be found. Glad I had some. I've heard you can make primers by saving the punched out ones, removing the anvil part, using a punch to flatten out the firing pin dimple, then using three match heads carefully removed crushed and pressed into the cup, then replacing the anvil part. Haven't tried it and it sounds time consuming. One can always use blackpowder and flint and steel, and maybe 409 shotgun primers which can still be found. Wish they would adapt bp revolvers to use 409 primers instead of caps.
Hunting is not a problem, with bows, snares, traps, bp rifles and pistols. Self defense is the problem.
