Hey, one of my holy grail rifles in a Spotless Model 54 Winchester in 30/30...
Got one. When I have the Unertl mounted on it, the stars are in alignment, and I squint just right, it'll put 5 180 NEI GC'ed cast lead bullets driven by 14gr. 4759 into an inch (and often less) at 100 yards off the bench. I don't know how it does with jacketed stuff, I never got around to trying any.
They got the magazine geometry right on that one too because it feeds everything as smoothly and reliably as you could please.
