Some guys are using cut off at the shoulder .222 dies and extended shell holders to make 9.3[.366] bullets from Hornady .375/225gr.The inside shoulder area of the die needs to be honed out a little to make .366 but that's it....22 Sav HP,223,219 Zipper,25-35,and 221 FB should also work same premise.Hornady .375 225gr come 100 to a box and when sized work well in the 9.3x57 and 62mm......................Harold
