Anyone shooting this cartridge? I have a few questions for our respected experienced shooters. 1. How much more effective is it than the 9.3x62? 2. Will it work through an 03A3 action? 3. What about brass availibility and cost? Thanks in advance for your input. Jim | ||

Assuming you are talking the 9.3x64B there are one of maybe two people on this side of the pond making brass. Figure $1.5-2 each. Ammo would be hard to find. I think A Square loads it at about $130/20. The case is 12% larger than the 9.3x62 loaded to equal pressure you should be in the 3% velocity gain area or around 75fps. Compare to older factory 9.3x62 lower pressure loads the gain would be higher. Should not be an issue to convert an 03. However anything you shoot with them will not be able to tell the difference. As usual just my $.02 Paul K | |||

the 74 is a rimmed long round.. assumign you meant the 9,3x62 or 64 the 62 is basically a 30-06 case, necked to .366 .. it should feed like a hungrey dog in a 1903a3 - think 366 whelen the 64 is a larger case head than the 62, and you pretty much can't make it from anything else (yes, i now you can.. but easier to just order it).. its functionally as powerful, those measured slightly less, than a 375hh ... hornady is making good .366 bulllets brass? don't load it hot, it will last 10 reloads, as long as it is NOT bertram... opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

My DEVA loading manual lists 770 mps as a maximum load for the 9.3X64B, compared to 670 mps with the 9.3X62, using the 19 g (293 grain)RWS bullet. That extra 100 mps translates into about 328 fps. The same manual lists the .35 Whelen at 739 mps and the .375 H&H at 851 with a 250 grain bullet, about the same difference. I use RWS brass in mine, built on a 98 Mauser. | |||

Opps, sorry for the mis-type! Yes, I meant 9.3x64B, and thank you all for your quick response. | |||

Loaded to std pressures you are probably correct. The 64 has a max pressure of 63,817 the 62 56,565. New rifle new quality brass I would have no concerns taking the 62 to the 63,000 range. As usual just my $.02 Paul K | |||

DEVA (Deutsche Versuchs- und Prüfanstalt für Jagd- und Sportwaffen, e.V.) lists the maximum pressures for the 9.3X63 and the 9.3X64B as 3900 bar and 4400 bar, respectively. DEVA is the German entity involved with research concerning and testing of hunting and target weapons. | |||

I am waiting for my Hartmann & Weiss in 9.3x64 Brenneke to come in (used), and found that Safari Arms also loads for the caliber. I plan to try 250gr Barnes TTX and Nosler Accubond bullets as an Elk and large Plains Game rifle. | |||

Yep that is what I said. 56,565 and 63,817. I put the 9.3x62 std pressure in the same box as the 257R and 7x57. If I was going to fire them in a older lower pressure action I would live the the std pressure limits. Since I load my 257 and 7x57 for the same actions that take a 270 or 25-06 at 65,000 I see no reason not to load to around 63,000. Each relaoder must make his own decisions. Loaded to equal pressure the advantage is around 75fps loaded to std pressure then the 300+ is probably more like it. As usual just my $.02 Paul K | |||
