Dukester, thanks, that's about what I figured.
Way out west here in Canada we don't consider tying a cow up and shooting it to be hunting. I must apologize for assuming we were talking about hunting situations. Easy enough to do I guess since this is the HUNTING forum and all the other posts were talking about HUNTING situations.
Of course I realize how foolish it would look if you beat the drum for the .22 as a deer cartridge if you didn't change course in midstream.
By survival situation do you mean like when you are lost and you've eaten all your trail mix and now a bear is advancing on your position? Is that when you whip out the .22? Cause if it is, here's a word to the wise. Get a short piece of rope and tie yourself down. In the excitement you wouldn't want to miss. You may only get one kill shot and you wouldn't want to still be alive when the bear arrived.
I see you have quite an arsenal there. I'd be concerned if someone, especially a friend sold me an accurate rifle for cheap. Usually those are the ones that command a higher price. I'm sure the 300 mag will work for deer, since you've used the .22 for much larger animals. You may have to work on the flinch but even is you get the shot in the general area the deer should drop.
BTW I shot 40 plus deer during the cull shoot. All with the .223.
The 5000 rounds from a mini 14 will certainly qualify you as both marksman/sniper and big game hunter, depending on the circles you move in. Excellent choice for a deer rifle.
The circle comment was not intended as a poke about you getting lost and wandering in circles eating your trail mix.
