I use instant rice to increase edible volume. The rice absorbs all of the moisture (from the finished product) and it all essentially tastes the same. Taco meat comes to mind.
I bought some lids from Wally yesterday and watch the jars. There always seem to be a few facings available but, only a small amount. you can't buy 5 dozen quart jars, etc.. But, there is one there, lately. Seems there is slow demand this time of year. Now might be the time to slowly fill in the blanks. I do not know how to "can."
Good time to buy ammo, too. that will be better than gold or silver. i bought .308 and 30-30 this week (one box). We got in some CCI SV .22 in box of 50 for $5. Steady slower seller. We have a fair bit of 12ga but no 20ga. Have some .28. which is slow to move.
So, 20 and .410 moves out quickly. I'm convinced 20ga is the best for most things. Will do it all in brush settings or clear. Pick up a dove with one hand and shoot one handed with the other.
