Both are .375 H's necked up to .411, right?

Much difference in taper and/or case length or is it just tiny difference in shoulder angle, like the .416Rem and .416 Hoffman?

Is one usable in the other (with resultant fire forming?)

Any photos of each?

Cheers

HH has a huge taper

I do not have a pick of the Pondoro, but out of the chamberdrawings in the A2 manual, it is pretty close to the .416Remington, but with a 27 degree shoulder measuring .496, compared to the Rem, which have a 25 degree shoulder at .487.

It should be able to fire the H&H in the Pondoro Chamber, but the two should be just as hard to find anywhere.

Here is a pick of the .375, .400 and .465 H&H.

Thanks Brent,

I have seen that pic...just forgot. Ja, that H&H has heaps of taper/long neck, almost like a belted .450/.400 3" !!!

The .400 Pondoro is interesting, but obviously too close to the .416 Rem to ever take off (take off being relative in big bores of course!)

Cheers

how long until somebody here buys a #1 and improves that long-necked case? In minutes or course.

The .400 Pondoro was designed by A-Square with a .397" bore and .409" groove diameter, and .409" bullets. The .400 H&H was designed to shoot .411" bullets. The brass is different as noted above (I do have a box of A-Square brass).

Holland knew about the Pondoro cartridge when their cartridge was designed.
