You say I'm good because I can look at a bullet design and know whether it will shoot. I rather like the compliment but seeing the ingredients for accuracy is quite simple with the critical points in good cast bullet design being mainly in three points. 1. Lube to bearing ratio over the bullets bearing length. 2 Bearing length and it's ability to carry the nose, or ogive. and 3. Ogive form, which gives the bullet flight form.
But just the visable form doesn't determine accuracy alone. The bullet MUST fit the particular gun well enough that it is delivered into the rifled portion of the bore with absolute precision.
Pretty easy to see an accurate bullet, with the above criteria, and 33 years of moldmaking experiance, fitting bullets to every kind of gun one can imagine from 8 bore down to 22.i
