sabot: What twist is your barrel? I'm guessing it's faster than 48?

Muley: I keep coming back to the Deerstalker, though I'm strongly considering the Country Hunter due to the faster twist since I would like to be able to use sabots. And I haven't exactly discounted the Deerhunter. I like the more modern stock and fiber optic sights.
I'm fairly stuck on a handy compact rifle, though I keep looking at Lyman's Trade Rifle for the increase in velocity. Is the increase even enough to consider it worthwhile?
The recoil isn't a great big deal, especially if it's only 1! Can always practice with a milder load I suppose. I never even notice when I shoot a deer with a 270 Win.

What was the original 45-70 load? Muzzle velocity? 70 grns (2F or 3?) under what?
