From "Ballistic Performance of Rifle Bullets, 3rd Ed." by Bryan Litz:
185 Juggernaut - 0.336" (2nd Ed.), 0.403" (3rd Ed.)
200.20X - 0.413"
155 Scenar-L - 0.395"
175 Scenar-L - 0.446"
Not sure why Litz' 3rd Ed. book value for the Juggernaut is so much longer than Berger's, when the 200.20X values are the same. The value for the Juggernaut in the Litz 2nd Ed. book is 0.336" as listed by @newbieshooter from Berger above. However, the 2nd Ed. book does not have the 200.20X bullet, as it had been released before the bullet was available. A difference of .067" seems like more than just Lot-to-Lot variance. Nonetheless, there can certainly be Lot-to-Lot variance in bearing surface measurements. I generally try to use the bullet dimensions listed in the book as a rough guide only.
