I run my TBAC's no problem on my Warbirds. I have two of them. My favorite hunting round. Thunderbeast is what TBAC stands for.What Suppressor did you go wit? I have not had good luck finding one that is rated for the pressure.
My caution would be about the Lazzeroni choice on barrel twist. The one I dealt with was a conundrum. Huge case capacity, but a 13 twist that wouldn't stabilize a 180 class bullet. The end result was only about 75% case fill running 155 hammers. With all that case capacity, my suggeation would be to plan on running 180 to 245 class bullets, so twist with at least a 10, but preferably a 9 or even an 8 to run the heavies with all that powder capacity.
Good luck with it, let us know how it turns out.
Has anybody ever built a custom 7.82 (.308) Lazzeroni Warbird. I'm interested in this round and as a hypothetical I wanna know if someone has ever built one and how they did it, what receiver, barrel, and stock did you use? I'm aware that it isn't the best round but I'm not worried about that right now.
...only if I had a hundred casings in my hand...wonder how hard they would be to find in these days a vare cupboards....
Kirby Allen's Raptor action has a .750" diameter bolt and can be had with the Lapua boltface.John usually has brass in stock.
you can find Brass, I have several hundred waiting to be fired , then a new barrel LOLJohn usually has brass in stock.
i second that, i have a high regard for the 550 cz action, in one test i read it was head and shoulders above all other in strength and it is controlled feed! i, like you, prefer beltless cases , but i am coming to the realization. it is a pretty minor detail. for example, i have 300 wm, 300 rum. 300 wsm, 300 dakota and in the number rounds fired hunting i can really say i find any appreciable difference in the brass performance, feeding etc due to the belt. as you state the 30/378 is a ballistic twin. my 2 centsCant beat the cz 550 for this conversion. The weatherby is also a gr8 action for this. But then u might just consider the 300/378 weatherby. Its pretty much a ballistic clone, but i like you would prefer the beltless lazzeroni.
sooooo, just build a 30 xc! it is new. beltless. cool, designed by tubb, no slouch. equal performanceFYI ....
While the 7.82 Lazzeroni Warbird is considered proprietary and technically does not have a parent cartridge to neck down and up from ..... It does share the exact same case rim & web dimensions as the 338 Excalibur/300 Pegasus that it is based on, both of those cases can be used to make Warbird brass, you'll have to cut them down, neck down to create a headspace shoulder & fireform, then turn the necks.. fairly simple work for wildcatters ..... John Lazzeroni shortened it to appropriate length for the actions and box/magazines he was working with at the time without sacrificing any performance, The Warbird is a very well designed cartridge that is capable of extreme accuracy, even in the factory Sako TRG-S m995 hammer forged barrels, it consistently shot sub moa 1/2" to 1/4" groups with hunting bullets, 180 gr & 200 gr Accubonds & A-Frames in the 3 rifles I messed with all shot better than most of my custom built guns with target bullets at the time ...
Most of the negative bs around the 7.82 Warbird was fueled by jealousy and sissy Nancy's terrified of recoil and loud noises, both of which are common in large magnum cartridges ......, my bro & I hunted Alaska with factory Sako TRG-S m995 7.82 Lazzeroni Warbirds for 10-12 years, killed a bunch of moose, griz, deer, black bear, wolves, coyotes, cranes etc... no muzzle brakes and alway loaded it hot for maximum velocity that it works best at for extreme accuracy and single digit sd's, most well designed cases run best at peak performance levels... the only issue surrounding the Warbird was the brass..... to reach the famed 3500 fps with 180 gr bullets ... you sacrificed the brass to two firings ..... now back in 2003 a 20 pc box of new empty cases at $99.99 was considered a lot of cash, the original brass was made by MAST Tech and is no longer made, new stuff is supposedly made by Hornady for Lazzeroni, heard it was better but I have not had the chance to try it yet to make any comments
NOW we "Circle back" and all of a sudden it is in vogue to send 30 cal bullets screaming downrange at 3500 fps .......
Need I remind y'all that John Lazzeroni designed an awesome 6.5 cartridge that was totally blasted by everyone at the time but now is considered the Holy Grail of 6.5's since wHorenady hijacked it in the form of 6.5 PRC ?
How many of you will champion the next "new" 30 cal magnum copycat because wHorenady did it ?
nothing new under the sun indeed .....
one thing I want to point out is that you CANNOT use 33xc brass to "Neck it down and shorten it" to make Warbird brass ... completely different web & rim dimensions on the two, the 33xc is based on the 338 Lapua case stretched to CheyTac length with different top of body, neck length and shoulder dims and is NOT usable to form Warbird cases.....
