Lazz 7.21 (.284) Firebird 162-168gr to 1000Y

I designed these high-capacity hunting cartridges myself between 1994-1997 ,,,,,,

with the Scramjet the only exception, all the Lazz Long-Mag cartridges use the exact same case design & dimensions and exact same chamber headspace ,,,,,

it was a challenge for me in the beginning to choose a neck length for the 7mm Firebird, and set the shoulder headspace, so that it would be the same even if the cartridge was necked out to .475 ,,,,,

ALL of the Lazzeroni cartridges were designed for HUNTING ,,, I have no interest in being a sniper or shooting a human ,,,,
 
Waveslayer ,,,

now to give accurate information ,, those current twist rates only apply to the model 2012 Lazz Rifles ,,,,

the model 2005s in the 7.82 (.308) Warbird caliber for instance use a 12 twist ,,,,

some of the early model 2000s built in the 90s used a 14 twist barrel, but less than 20 were built with that 14 twist ,,,,

Please remember in the 90s, 500 yards was considered EXTREME range in the field when hunting, so when I released the 4000+ fps load for the Warbrid, that you could sight in dead on at 400 yards and be no more that 3.9" high anywhere in between ,,, that was a HotDog rifle back then ,,,,

AND Landed me on the cover of Rifle Shooter Magazine as ""THE-FASTEST-GUN-IN-THE-WEST""" ..

And that is the niche crowd that your rifles are perfect for, those that can afford an expensive rifle and want to be able to hold on fur out to 450-500 yards. They do an excellent job at that.
 
One thing that is different today rather than in the 90s or even 2000 is that more and more folks can build more of the rifles ourselves. I will admit, when I built my big seven I had studied both the lazz and Allen mags and choose the RUM brass just for the cost of the receiver and brass. I also shoot an Edge so I already had a stockpile of 300rum and 338 edge brass. I have under 6000.00 in my 7 Ultra Rogue including reamer, hydro die, custom Whidden dies and Nightforce ATACR 7-35. it will launch a 168 at 3420, 180 3300+, 195 3200+. 30 " Kreiger 5R 1-8.5. I also love the fact that the powder I use is 6 dollars a pound :)

I may be missing the point someplace along the line here, but I cannot figure out how the latest crop of 6.5 shorts/longs can be as effective on game animals at the longer ranges to 1000 yards, as the Lazzeroni 7.21 (.284) Firebird and 7.82 (.308) Warbird.

Certainly the Lazz rifles are more expensive than most folks want to pay, but the Lazz calibers themselves are some of THE most effective on game anywhere in the world.

I think we all just need more in depth information regarding these awesome flamethrowers! If nothing else it gives us wildcatters more expertise. Funny, I bet there are quite a few that are almost direct copy's of the Lazz Magnums & folks don't even realize it.

May be wrong about similarities . But there are people necking down 300 Norma to .284.
 
The 300 Norma has almost 20% less capacity than the Lazzeroni. My research shows, Warbird 120 gr H2O, 300 N 103, 300 Wby 101, 300 RUM 110, 338 Lapua 108 (wik says 116), 30-378 133. I believe the 300 Edge was closest at 118.

Yes. When I held the firebird it looked like the 7x300 Norma but improved. Just an observation
 
Yorke ,,,, recommended inside bolt face diameter for big Lazz cases 7mm - .475, is about .596" ,,, Lazz reloading dies available from the Hornady Custom Shop ,,,
