ok, what the heck is this stuff?

[ZRX61]

The two rounds in the middle? .50 & 7.62X54R for scale...

Looks like it could be 505Gibbs. There are a ton of big game cartridges though.

Belted, thumb sized case.
Large diameter round nose bullets.
Looks like a belted .375 H&H Magnum case. (?)
Necked up to .416?
Elephant gun ammo.

Is there a headstamp?

Ah HA! Found my glasses & can now read the end of the case. Apparently it's Weatherby 460 Mag.

Based on the overall length it looks like a 505Gibbs but the case length seems short. Looks like the case is coming in around 3 inches but from what I have read the 505Gibbs is around 3.15 inches long.

Can you post the actual overall length and case length dimensions? Can't tell in the picture if the ruler is lined up exactly. Could of course be reloaded ammo that had the case trimmed. Don't know what the tolerances are for the trimming of the case on a round like that.

[krzgoat]

Nevermind.

MMMmmm, Weatherby...
