This includes the nose & body lengths I forgot for the two bullets in Post #4 (sorry for the clutter):
1. Hornady #45137 185gn JSWC "TAR" Encapsulated: bullet length = 0.521"; body length = 0.295"; nose length = 0.226"; OD = 0.4505". [Candiru had posted a Hornady COAL of 1.135" for this bullet.]
2. Hornady #45177 230gn JRN Encapsulated: bullet length = 0.643"; body length = 0.282"; nose length = 0.361"; OD = 0.4506". [An undocumented source had posted a (supposedly) Hornady COAL of 1.230" for this bullet, but this seems to short to me. I think it ought to be about 1.255".]
IMHO, inclusion of the nose & body lengths will make this data more useful. I don't think a starting COAL can be determined (lacking one from the manufacturer) based on the bullet length alone.

On a good day, can hit the broad side of a barn ... from the inside
I'm a newbie, would not the base diameter be .451?
in "general"...Originally Posted by dcdornac
yes for jacketed and plated slugs
Lead slugs are typically .452
..L.T.A.
And we don't want to know what the manufacturer claims the OD is. We want to know what it really is - so we measure it.

And as we find more plated bullets, and some manufacturers (like Speer?) who sell bullets as "total metal jacket" that may, in fact, be plated (to an unknown thickness), we can't assume anything. Berrys' plated 230-grain round nose bullets are .452" diameter (or a shade less, but bigger than .451").
