I would fathom that the wear ratio of loading conicals to sabots would be closer to being 10,000 sabots to 1 conical.
That seems logical at first blush
arcticap.
However, you must realize that lead is 3.1778 times harder than the average sabot. I used that figure, and factored in the average lubricity quotients of spit, olive oil, Crisco, and bore butter to adjust the likely wear factor for both patched balls and lubricated conicals - thus arriving at 3.2 and 2.9 bazillion shots respectively.
I'm sure that figure is correct. DO NOT MAKE ME RECALCULATE IT!!!

After all, it's just a rule of thumb.
