Thread: 9.3x62 loading

Greetings @JohnDuxbury,
I have come up completely empty on data for AR2207 in the 9.3x62. The nearest I got was some data for H322, AR2219 in a wildcat 9.3 on the 350 Rem Mag case developed by John Barsness (gun writer) and Charlie Sisk (gun maker). The usable case capacity of the wildcat is about 1.5 grains less than the 9.3x62 so the loads will develop less pressure in the latter. John used 52 grains of H322 for 2,415 fps in a 23 inch barrel in his wildcat. The load was tested in a pressure trace system at less than 60,000PSI. John wrote an article in Handloader 237 about the round.
None of this helps with the question form your OP. The data offered for N130 is likely the best to be had but it is a different powder. AR2207, H4198 is a very flexible powder used a lot in reduced loads and cast bullets which is likely where your data came from.
Best of Luck and Regards Grandpamac.
