I owned a drilling in 9.3x72R which is diff. than the 9.3x72 Sauer. My rifle used a .364 dia. 193 gr bullet at 2100 fps. Brass and loaded shells are available from Huntington and the Old Western Scrounger.Dies are avl. from RCBS. I also had a cape gun from Austria in 16x8x72 rifle which was the 9.3 case necked down to .318. It shot a 196 gr bullet at 2200 fps. The best way as mentioned is to chamber cast and slug the bore. I killed deer with mine and it did a great job. Regards Rich
