I finally got a chance to do some more shooting with the 9.3x57. As an experiment I tried paperpatching some 200gr .358" cast and jacketed bullets. With 44 grs. of IMR 4895 both bullets gave groups of about 1 1/2- 2" at fifty yards. Conclusion? Not worth the fuss and bother. With 49 grs. of Varget and 200 gr. Hawk bullets, fifty yard groups were right at 1". I'd definitely recommend High Plains reboring based on this one experience.
