What caliber's were the Super 16 Barrels offered in?
I used to collect these barrels and had them in 22LR, 22Mag, 223, 7-30 Waters, 30/30, 35 Rem, 44 Mag, 45/410. My son still has the 22 Mag. I never had a 22 Hornet, but I’m sure they were offered.
What forend fits? (I think it's a Carbine)
It was the standard forend for the carbine tapered barrel.
Do they have the same taper as the 21" Carbine Tapered?
I think I would like one. 22LR is an obvious choice, but I don't need that.
Did they come in 7-30 Waters or 30-30? And how did these perform. Particularly the 30-30 with factory ammo?
150 gr Remington 30/30 factory ammo did 2270 fps. I only shot it for groups as a pistol with the open sights at 25 yds.
120 gr Federal 7-30 factory ammo did 2660 fps and 2 1/8" groups at 100 yds. My handloaded 120 gr Hornady SSP loads did 2500 fps and 1 ½" groups. Scope was a 1 ¾-5X.
