B92's in 44 seem to work well with jacketed but most users report poor results with conventional size cast 44 bullets. The groove diameter is large and the rifling very shallow, which doesn't allow much of a grip for undersized bullets. Because of the large throat bore alignment with undersized bullets to my mind is also a problem. A fatter bullet fills the chamber and also helps to align the bullet in the throat. The throat is so long that you will never fill the throat with a bullet that will cycle through the action.

The best mould I have found is Mihecs 44-300 gr HP mould. This is a GC design with 3 crimp grooves. It feeds really well too. Loads using W296 are about as accurate as my jacketed loads - around 1.5" at 50 yards, which is about all I can muster with open sights these days.

I have often wondered whether there would be interest in a group buy for better sized barrel with a cast friendly throat to suit the B-92's?
