I'm new to the 9.3x64, having picked up a Mauser 99 {Voere action} last December. Took several months to aquire some brass but finally got 100 rounds from Huntington. My first random load with the Speer 270 gr groups into an inch so I'm pretty pleased. Wish I could report knocking off scores of big tough beasties with it in exotic places but I can't. I intend to blast a whitetail or 2 with it this season just to get in some field time with it. I really like the 9.3s. I have a CZ 9.3x62 and am going to grab the first Ruger #1 9.3x74R that comes available. Somewhere along the line I'll have a Mauser rebarreled to 9.3x57.
