Brownells Ammo Tease.

Ok, so Brownell's teased this image today asking to "guess the caliber."

So, first thing is that's clearly a Weatherby belted magnum case either blown out or trimmed.
And the projectile looks like one of the elegant high-BC 7mms.
The 460wbymg is also the 375, if memory serves. But 7-460 sounds cooler []

Anyone else keen to guess?

 

To me looks like a 40mm case necked down to .50 bmg

 

A .22 LR that I accidently fired in a .22 WMR cylinder?

(J/K)

 

20mm cannon x .50?

Maybe.

Definitely not a Weatherby, the shell on the right has printing on the belt.

Stay safe.

 

Looks like a 20mm-105b with a 750 hornady Amax.

 

23×152mmB Russian case necked down?

That’s not a Weatherby or any other conventional belted magnum case. The belt is too thin and the extractor groove is too wide.

 

That's a Weatherby .225 Belted Preposterous.

Extreme high velocity. Vaporizes the target on impact, but you only get twelve shots before the chamber throat has to be replaced.

 

Yeah, that case is spinning me for a loop. The 20, 25, & 30 mm "cannon" case are not belted, the case head is strong enough as is.
And they have deliberately not given us anything that offers scale to compare to.

(Oh, yeah, this is entirely a goof, and Brownell's meant it that way--but, my curiosity on that case dug in hard enough to pose the question.)

Did Jeffries or Gibbs "do" belted cases?

 

Just a 23mm Russian shell from a ZSU 23-4.. although I wonder what process was used to neck it..

 

That rim seems a lot more rebated, and the belt a tad skinny--but, neither photo has a lot of scale information where it counts.
.50mbp down to that 23mm case would probably have the "look"
The 23x115 has a 26mm base.
The 23x152 has a 38mm base diameter.

The latter could be pretty likely given the proportions of a 12.7 bullet versus a 38mm base.

 

I couldn't even guess.....but I want one.

 

It's the Lazzeroni 500 Asteroid, aka Planet Killer

 

At the club we would play a game, guess the gun and we would pick guns from movies. One that would stick people is the gun Joe Kidd has.

Hard to tell from this pic


But the video, While not common, much more easy.

 

Looks like something I need to fire

 

.277 ?

 

Just one of the many German sporters of the time.

 

Now that thing looks like it would blow a lung out.


9mm?

 

Not that I saw. Brownells let the thing fade away middling quickly.
