Thread: 9.3 x 57 load data

Brought a box of Norma ammo chronied some , pulled some to get an idea of fill height and charge weight then looked at case capacity versus the 358 which is virtually the same.
I also had a look at some 9 x57 data which was obsolete using 2206
2206h and 2208 are recommended for the big brother the 9.3 x62 and the 358 so it seemed logical to try.
I loaded up a small ladder of 2208 and 2206h and shot them over the chrony and settled on 2206h as I have the most of that.


I'm still about 50 fps behind the factory with 47.5 grains and might step it up a little but its going ok as it is still I would like to crack the 3000 ft lbs mark and another half grain might get me there.
Primers still have nice rounded edges not that primer condition is a great tool but if they're not flat to the edge of the pocket you still have a little room to move around in..

I think you maybe struggling to crack 3000fps Marty
