Pic related exists, but no doubt it was packed with as much gunpowder

Shotgun and rifle-two totally different categories of powder. Shotgun powder has a much faster burn rate. Rifle powder will not work in this application.

3 1/2 inch 12ga. shells max out at about 14,000 psi, per SAAMI. According to the same people, .308 tops out at about 62,000 psi. That would be a spectacular failure on the part of the shotguns receiver, and serious injury or death on the part of the user.

Firing rifle pressures out of a shotgun?

What happens is nothing good. Barrel will bulge and split. Bolt will likely blow out the back of the receiver and into your eye socket.

Now if you were to make a similar bullet in .50 Hectate or .458, or any other large bore rifle you could have a pretty devastating round, assuming it works as advertised.

How about double the pressure (28,000psi) with a very thick-walled brass casing?

>>31970570
>.50 Hectate
The fuck is that?

>>31970885
you still have to worry about bolt thrust. Even if the cartridge can contain the pressure it is still being forced backward up against the bolt. The locking mechanisms on shotguns are not designed for those kinds of pressures and they could fail.

>>31971083
No fucking clue.
He could've meant the round that the PGM HECATE II fires (.50 BMG).
Probably a fudd or just wanted to say .50 bmg in an exotic tone like those guys calling 7.62x39 ".30 Russian"

>>31971092
>PGM HECATE II

I want one of those. Also yes, it sounds like he's a legitimate fudd. Not technically wrong about what would happen, but a bit weird.

I feel retarded.

>>31971191
>".30 Russian"
Boy does this trigger my autism. Which one?
7.62x39, 7.62x54r, 7.62x25, 7.62x38r there are probably others.

The fuck does Russia like 30 caliber some much?

>>31971191
.30 Russian is 7.62x54r though

x39 is .30 Soviet

To my knowledge it goes as such...

7.62x25
>7.62 Tokarev

7.62x38r
>7.62 Nagant

7.62x39
>7.62 Soviet

7.62x54r
>7.62 Russian

I guess you could replace the 7.62 in the nicknames with .30, if you wanted to sound like a Yank, but I've just come to understand that these are at least relatively well known nicknames. I don't use them at all, I actually call them by their full Metric names, but if I were to decide to say "7.62 Soviet" then I assume people would understand that I meant 7.62x39. Wasn't there some kind of .44 Russian used in old revolvers in the mid-late 19th century or so? I don't think there was any .30 Russian though, and I would never call 7.62x54r that. 7.62 Russian perhaps, but yeah, even that would likely contuse people. I also call the M1 Garand by its proper name; M1 Rifle. Been doing that for years; M1 Garand is just a nickname even though it's practically its official title by this point.

I had this one range buddy and he actually got annoyed at me with it. "Do you mean the M1 GARAND or the M1 CARBINE; calling it M1 RIFLE could mean either one!" Or something like that. I dunno, he was a beta mall ninja manlet so I didn't worry too much about what he thought or said.

>The fuck does Russia like 30 caliber so much?
IIRC, standardizing on a caliber let them use the same tooling for various different barrels.

>>31971599
>Wasn't there some kind of .44 Russian used in old revolvers in the mid-late 19th century or so?
Yep. It was designed by S&W and used primarily in their No.3 Russian contract guns. It also served as the parent cartridge to .44 Special and .44 Magnum.

Replied to the wrong comment there, champ

Those were the actual names they were made under in the west.

He meant fudds called it 7.62 Russian because "7.62x54mmR" "made in russia therefore 7.62x54mmRussian"

>>31971748
7.62 Russian as a name predates the r for rimmed designation.
It was 7.62 Russian since it was a .30 caliber for Russian rifles. The Russians simply called it three line cartridge for rifles then 7.62 for rifles after the revolution.

>>31971748
I know but everytime i see ppl at gun shows ask for 7.62russian or 7.62 soviet they always hand them ak food.

>>31971535
Everyone likes thirty caliber.

See: .308, .303, .30-06, .30-30, .30 carbine

>>31971788
Maybe i should ask for ak food at the next gun show and see what happens. Maybe make some joke about how its a hungry little bugger.

>>31971798
.30 probably hits the sweet spot in bullet physics.

>>31971876
More like in manufacture.
Fairly standard size drill bit with a bit of reaming afterwards gets you right around .3"

>>31971901
Well, it does show just how many different kinds of .30 are we talking?

Also, I'm curious. Is it possible to fire almost any .30 bullet (30-06, 7.62xxxx, etc) from any other .30 barrel?

I know the .30-06 and .30 carbine were made to work together with the Pedersen device, and it seems to work the same concept as the the medusa revolver. Right?

>>31971876
Try 6.5mm
