Either cartridge will put you in "fast company" but they are both pricey to shoot. I chose the Lazzeroni because I practically stole it back in 99 (NIB dealer cost $450, that has nearly doubled since!). My step-brother is a Lazzeroni dealer and even he quit shooting a Warbird because he just could'nt mentally get over the fact that it cost him $5 to pull the trigger. As for the big WBY, its a fine rig as well but being a WBY (double radiused shoulder and belted case) it typically is'nt as accurate as the Sako/Warbird-Firebird rig (unless you are willing to spend twice the money on a custom Mark V and then shoot custom ammo!). The 'bird typically outshoots the big Wby by 100fps or more with most bullets, even a larger margin when talking about 180+ grain bullets.
On the negative side (Lazz wise), the Wby ammo is MUCH easier to get than Lazzeroni ammo as any firearms dealer can order Wby ammo from a multitude of wholesalers. Lazzeroni ammo is only available from Lazzeroni Arms Inc in Tucson, AZ and JoeBlow gun dealer likely will have to go thru the credit check, sign up avenue or prepay with credit card before anything is shipped to him.
One thing about it, both are THE king and crowned price in the 30caliber world and leave the rest of the "magnums" quaking in their brass!

ps
The Savage/Lazzeroni is'nt available in the Warbird, but in Lazz's shortaction mag the Patriot. A good buddy of mine bought one lastyear and it is a FINE rifle and is the ballistic equivalent of a 300Wby Mag but in a lighter and quicker handling shortaction gun... did I mention it kicks like an abused mule???
