Given how ammo is fucked for the foreseeable future and how successive ammo shortages always seem to get worse so stocking up on years worth of ammo will probably be necessary going forward. How does one get into trapping small game? How much of an issue is having animals that you can't legally trap get into your traps? How much time can one expect to take for the meat they get vs going out with a .22?

Where would I look for good reading material on this subject? Most of the talk I've seen about trapping in the past has focused on bug out/survival scenarios where laws don't matter and anything to eat is better than nothing, so I figure I really can't go off much of that.
