It depends on how good a deal you can find on the raw product. I've canned fresh sockeye that cost me $2.99 a pound. I put up 30 lbs of it at once, and I can guarantee that the cost per pound was way less than what you'd pay for canned sockeye salmon at Costco. That's even factoring in the amortized cost of the jars, lids, and the canner (the cost of which goes down every time I re-use them).

Normally ground beef sells up here for around $3 a pound for 80/20. I found a great deal on cross rib roasts (lean and a bit tough if you cook it past medium rare) for $2.29 a lb. The ration was like around 93/7 lean to fat, and I ground it myself then canned 30 lbs of it. Ground meat in 8 oz foil pouches costs about $2.50, or $5 a pound, and is full of other things besides lean meat.

Then there's the deals I get from others for moose meat, deer meat, salmon, and so on for helping them grind/can their stuff using my equipment and know-how. The cost on that meat is very low comparatively.

But you're right, it is tough to compare commercially canned meat products to home canned cost-wise. I don't factor in my labor costs, which if I billed my standard rate would probably make the home-canned stuff exorbitant. But since I am doing something I enjoy that helps me relax and forget my troubles, I sort of write off the labor part of the bill. After all, I wouldn't factor in labor costs in my fishing trips vs. picking up a fish or two at the store.

I guess if I were to make it a business venture, my home canned meats would be sold at a premium, as would my sausage and baked goods. But then I know some people who would be happy to pay a fair price.

Home canned will always trump store bought. I don't ever have to worry about the mfr taking shortcuts with my product.
