For what it's worth, I've home canned beef and chicken too. Assuming that canned beef isn't as good as fresh is a possible mistake. I started with bargain basement priced beef (don't remember the cut right now), followed procedures found in a canning book put out by Ball canning jars, and ended up with beef roast that was as tender as the finest filet. The chicken was really good too, by the way.
Now don't get me wrong, I'm not suggesting that anything mass produced is going to be as good as home grown/hunted/processed whatever, but I'd have to try it before I dismissed it out of hand. I'm also not suggesting that home canned goods are the best choice for a bug out bag, but having a well stocked pantry full of wholsome, nourishing, and TASTY food makes me a lot more comfortable about whatever may come my way (blizzard, tornado, terrorist shutdown of supplies, or just a long stretch of unemployment). I didn't start this to get into a "Survivalist" discussion, even though it might sound that way, but preparedness goes well beyond our PSK and the "next 48 to 72 hours".
Some of the depression generation's ideas and thoughts aren't so "old fashioned" or "far out" when you stop to give them some thought yourself.
Just my two cents worth.
