I have a .280 Rem., 300 Weatherby, 9.3 X 62 and .375 H&H, the problem I have had is feeding with the .280 and 9.3, Montana could not make the 9.3 feed reliably. I sent both the 280 and 9.3 to a gunsmith that is verry good at feeding and both feed great after he worked on them. The positive thing...
