Info that I've been able to find about the SE is that they were made in stainless steel and with a walnut stock. Mine misses on both counts.
Initially they were available in .458 Win Mag & .375 H&H. .300 Win mag was added later.
Edited to reflect proper information:
I just finished reading a review from the July, 1994 Petersen's Hunting magazine. Seems that the rifle was initially offered in .338 Win Mag, .300 win Mag, and .458 Win Mag.
The review shows a totally different rifle from mine. The one that they tested was stainless in a walnut stock. It had 3-leaf express sights, muzzle brake, barrel-mounted sling swivel, and a blind mag.
In 1995, they offered it in .425 Express. .375 H&H was added in 2000. .338 was discontinued in 2001, .300 & .375 discontinued after 2002. The rifle was dropped from Savages's catalogue after 2004.
I bought my rifle as one of Savages "Package Rifles" It's got a tupperware stock, detachable mag and is in blued steel.
I think that maybe I got a rifle built out of "leftovers" from the factory?
Anyway, I like it................shoots handloaded 220 grain loads at 2795 fps into groups under 1", and shoots Hornady "Heavy Magnum" factory ammo into really nice groups as well. I probably haven't fired 150 rounds out of this rifle. Think I'll maybe get serious about using it a bit more
