Winchester 9422 Xtra Magnum
Shoots MOA with 45-50 grain Federal ammo
Yes, the 9422M shoots the 50gr bullet very well. I don't know the rate of twist, but it is enough. The discontinued 50gr. jacketed are thumpers. I bought all that Midway had when I heard they were discontinued. That was many years ago.
Side note. I still can't get excited about any lever gun with a scope mounted on it. Receiver sights I dig.
