I designed the Lazzeroni Warbird/Titan cartridges in 1995 specifically to meet or exceed the performance of the 30/378--338/378 Wby Magnums, but without the belt ,,,,, AND all the recoil associated with the big Wby's ,,,,
beltless, 30 degree sharp shoulder, excellent factory throat/chamber dimensions ,,,,,, keeping the OAL at 3.650" or less, with bullet ogive to barrel land distances at minimum ,,,, for proper feeding/function in the Lazzeroni 3-round staggered magazine box ,,,,
A friend of mine in Az put together a Warbird for me about 1996 or '97. It was built on a Rem 700 with a 27" Lilja barrel in 14 twist, and sat in a McMillan HTG stock. I made my first 500 yrd kill shot with that rifle and never even touched the knob on the scope. I also killed a couple of bull elk at over 800 yrds. That rifle was a ton of fun, and the barrel lasted pretty close to 1500 rounds. Near the end of it's life I started to get unexplainable flyers. Like 3 or 4 in a nice group at 700 yrds and one 4 feet low. So I shelved the rifle a few years ago until I get around to putting a new barrel on it. The new tube will have a bit more twist and probably finish at 28".
I'm glad to hear about the change in brass suppliers. I had a few issues with some of the MAST brass. I was starting to think about a 30 cal wildcat on the 338 Lapua. But now I may rethink that.
It may be time to get on the ball and spin a new tube on my "Bird".
Welcome John! I have been a Warbird nut for about 10 years now. I first bought the Sako and then had my smith(Jerry Simison, Detroit Lakes, MN) build one for me. I bug him every time that I am in his shop about a Lazzeroni cartridge board he has on his wall and if he will sell it to me. I have never seen one on your web page but would love to get my hands on one. Do you still offer them? I have been considering a custom Firebird for my next project.
