When using Greenhill's Formula to identify maximum bullet length, what do I do with patch thickness? What I'm asking is whether the nominal bullet diameter to plug into Greenhill's is just the bullet diameter I intend to use, or do I include patch thickness (.010-.015 inch) as [part of] bullet diameter?
Since I'm wanting to have a mold made that will yield the heaviest bullets for the bore diameter and twist, kvetching out the last few grains of weight is important.
The rifle in question is a double rifle, bore size will probably be .72-caliber and 1:72 inches twist.
