Lasercast is closed today,so thought i'd as here. Pretty sure the book is just wrong,but here goes.

the diagram of that round in 3 books shows a loaded length of 1.590
However..looking over at the bullet/powder specific length, many of the oal's are show ans 1.600 and 1.610.

EDIT. I JUST NOTICE THAT THIS IS THE RIFLE SECTION,THOSE LONG COAL'S ARE NOT SHOWN IN THE PISTOL SECTION,so I'll go with that as I always have.

Is their book just wrong and this is the 1st time in twenty five years I picked up on it ? btw i've always just gone by the diagram.

what say you ,my friends ?

Much worry about not much to worry about.

I agree.

The first time I use a bullet for a specific cartridge; I'll seat to the cannelure, then test in the specific firearms they are intended for.
The only time the COL comes into play, is when I measure it to record for my data sheet. It is a second consideration, merely for administrative purposes.

Some 357 revolvers will only accept a shorter OAL than other revolvers. The S&W 27 has a short cylinder, the Ruger Blackhawk has a longer cylinder. Some jacketed and cast bullets have 2 crimp grooves to fit either gun.
Pick an OAL for your gun and work up the loads with it.
