Savage offered their bolt rifle in the 425 Express, at least for a short while. I saw a couple of them locally when they came out.
It actually seemed like a neat cartridge from the 300 Winchester brass.
This is a little hype about it:
"Top of the hit parade at the '95 SHOT Show was the hot new hunting rifle from Savage Arms chambered in .425 Express. Savage has made an astounding comeback in recent years under the astute leadership of company president Ron Coburn.
The gun is the Model 116 Safari Express, a stainless steel bolt-action with folding leaf express sights, a factory muzzle brake and select walnut stock. Unlike many other so-called "safari" rifles, the Savage 116 is value priced, allowing anyone to own an African rifle even if they never actually hunt elephant.
The .425 Express is an exciting cartridge that fits in a standard .30-'06 action, yet delivers magnum power levels. It utilizes a 400-grain bullet from the classic .404 Jeffery and delivers 2,400 feet per second - identical ballistics to a .416 Rigby."
