If anyone is interested in playing around with this old wildcat, I listed a Brown Precision in that caliber in the Firearms Classifieds.

Its a decent caliber I suppose, but probably overbore capacity..The 7 WBY is a better option IMO...but to each his own..What your talking about is a 7 STW that only differs in that the STW has a standard blown out shoulder and the WBY has that rounded shoulder, the name has slipped my old mind for now!

Double-Radius?

I "believe" the 7STW had no case modification except caliber. The 358 STA did have the case blown out and maybe other changes.

One of the older Sierra loading manual had loads for it. I think some woman won a 1000 yard shoot with it, the Wimbledon?

Or it might have been the 6.5/300?

Would prefer 7mm/300 to 7mm Wby. Apart from the ballistics 300 Wby brass is plentiful and it is a simple neck down and load them up.

The 7mm STW is the normal shoulder diameter of belted magnums, about .480 or .490, forget which one.

The 358 STA I think was .505. I have owned a few of them. The 450 Ackley is the same, both are about as parallel as the case can be.

There have been some fuckups with the 358 STA with dies and reamers because of those being done as a straight 8mm Rem neck up.

I'd prefer the 7mmSTW myself.
