The single locking-lug on the bolt limits them to 40,000 psi loadings. They are a bit more powerful than the venerable .30-30.
So long as you limit yourself to the inherent clean-kill range of inside 250 yards, +/-, they're great shooters.
IIRC, they have a relatively fast twist, and are more accurate with the heavier bullets. Say, 180- to 200-grain...
I have one I've played with some. Very enjoyable to shoot.
