Phathead
I would get him down a bit. It is a little bit of a specialized twist. I personally like a fast twist 45cal. Shoot the heavier 40cals (200gr+) in 45 sabots or heavy for caliber conicals if they will shoot well. Use cheaper XTPs or GoldDots for range and fun shooting.
Ive been trying to find a cheap Pursuit Pro in 45cal just because they had a steel frame and you could add a ML shotgun barrel to them. I want to cut it down to carbine length as a project. I cant bring myself to butcher one of my Knights.
