360 buck hammer

[catpop]

Question:
If the new 360 Buck Hammer cartridge can push a 358 bullet out of a lever action at 2400 fps,
then why can’t the same lever action achieve the same velocity with the 35 Remington cartridge?

1.800 max pistol case length aside, this extra velocity is the only reason the buck hammer excels over the time proven 35 Remington. Jmho

What am I missing here?

Edit:::;;But I guess I didn’t ask the question correctly.
If the 360 buck hammer is rated 50,000 psi chamber pressure, then why can’t the 35 Remington be rated at the same at the same pressure if is used in the same lever action?
I thought the chamber pressures of the lever action locking mechanism was the limiting factor.
But I see now the same action is supporting 50,000 psi instead of just 33,000 for the 35 Rem?
I’m confused

The Remington is a lot lower pressure.

The cartridge itself operates at that lower pressure regardless of action.

Because the 35 Remington pressure was agreed upon a long time ago. It's a 33 ksi round because it's a 33ksi round. I know that sounds arbitrary because it is.

I like the Buckhammer round on paper. Never shot it but it looks like a great round. Brings the 38-55 into the modern era.

Again JLWILLIAMS makes my point. 38-55 is a round from at least 100yrs ago. Brought to modern day and you have the 375win.
Saying that... if you're a reloaded, the 360 may be a better round as cases may last longer and easier to load as a straight wall.

Thanks for all the input!
That 35 Rem +p mentioned on another tread will definitely get more attention in the future.
