You don't want to know what I have.....
Your mix
Semi auto Shotgun, plugged I assume. So 1 in chamber 2 in the tube. I would want a side saddle for reloading (or speed loader). Keep a box or 2 of bigger shot and/or slugs
357 mag revolver 6 rounds , reloading can be fast with moon clips or speed loader and spare 6 (or 12) handy would be nice. I'd have 50 or so hollow points on hand just in case. FMJ is not for self defense.
30-06 bolt really only useful outside (or through window). Have what ever use for hunting handy. Not sure I'd have loaded unless I was expecting someone. Still would have a couple of boxes of ammo.
I'm a backups have backups kinda guy in everything. meaning I have at least 2 of everything I use, if not more. Like multiple tractors, chainsaws, mowers, etc.
