358 STA brass?

Why would you want pre-formed brass? It won't fit your custom chamber as well as .416 Remington brass run into your resizing die just far enough to allow it to chamber. This will leave a small "shoulder" where the larger 416 brass was squeezed to .358 and make for perfect headspacing. I suspect you'll find fully as good accuracy or better on the first shot with brass formed this way as with pre-formed brass.

I would agree with Stonecreek. You would be
better off custom forming it to your chamber. This is how I do the wildcat cartridge I make brass for and it works fine

I got mine at Superior Ammo in South Dakota. The brass was perfect and shoots great. Good Shooting.

Vince,
Just run a .375H&H case into your .358STA sizing die. Fireform with inexpensive .357" handgun bullets and you're done.

If you must have correctly-headstamped brass, contact MAST or Owlnet.

Thanks for the info guys. I know how to form the brass, but I have a friend that is worried about bringing brass into Canada this year that doesn't say the same thing as his rifle barrel. I don't think there will be a problem, but he is worried about it.
Thanks,
Vince
