Default What's the formula used to determine shot size for various bore diameters

I believe you used your bore diameter & multiplied it by a four digit number to determine the largest shot size for tiers of three.

I found it, it's .4641.

Multiply the barrel diameter with that & you'll get the proper shot size.
Evidently .45 caliber pistol balls stack well in a 1" blunderbuss
