|See the suture line?|
|South Dakota is a freestone. That means the stone lifts right out of the ripe, cut halves.|
|I was harvesting the seeds for planting but could not bring myself to eat four pounds of plums in one sitting nor to throw them away.|
|Cold-pack pints are 25 minutes of boiling. Then I took the jars and the kettle outside to cool off. Our A/C does not need the extra load.|
Sphere packing is not very efficient. Shot in shotshells and fruit in jars will run about 60%-to-65% efficient.
Why might that be useful?
Suppose you were reloading 20 gauge hulls that somebody had given you as a gift. Also suppose that your standard "load" is just a bit too bulky.
You cut off the petals of the wad and weigh them and learn they are 9 grains.
How many #8 pellets does that equate to?
Since the wad is made of low-density polyethylene with a density of approximately 1.0 grams per cc and lead has a density of approximately 11 grams per cc, if spheres packed perfectly efficiently then the petals would be the equivalent of 11 * 9 grains or 99 grains of pellets. At 1.1 grains per pellet of #8 shot, that would be 90 pellets.
But since we know spheres are not very efficient at packing, we have to multiply that 90 pellets (100% efficiency) by something between 60% and 65%.
If we use 60% we get 54 additional pellets. If we use 65% the math predicts 58 pellets. Flipping the computations around, cutting off the petals of the wad are the equivalent of shaking out 54-to-58 pellets of #8 shot.
Another use involves calculating how much syrup you will need to make when canning near-spherical fruit. Plan on 12 to 13 ounces of syrup and you will be close. If the fruit is soft, you can squish them a little bit to get better packing efficiency.
