Has anyone got loading data preferably using ADI or other regularly NZ obtainable powder, for either Norma 232gr or Speer 270gr bullets?

Hi DDD
I have a Husky in 9.3 x57 and ahve a load for 286 grain projectiles. I'll get the info you later. I had to use 8x 57 cases and neck them up, and it is a lot of fun to use, not so much for the target species. Mine is doing about 2100 fps.
Will post details later

Hi DDD
My log shows I loaded 286 gn Lapua with 45 gns of 2208 for 2100 fps. Hope this helps, they are a lot of fun.

Cheers

DDD, 49 gns of 2208 with a 250 gn proj in the adi manual is listed as a max load. start a few grains lower and work up.
2206h should work fine also, i'd start 3-4 grains below your starting 2208 loads

Greetings DDD,
I found some recent load data for the 9.3 x 57 in an article by Gil Sengel in Handloader magazine April 2013. Gil worked up his loads to approximate Norma Factory pressures and included data for both of the projectiles you mention. He used IMR powders but AR2206H and AR2208 are close to IMR 4895 and IMR 4064 respectively.

His max loads for the 232 grain Norma were 48 grains of either IMR 4895 or IMR 4064 for 2,287 fps and 2,255 feet per second. Max loads for the 270 grain Speer were 44 grains of IMR 4895 for 2,087 fps and 45 grains of IMR 4064 fps. Factory 285 grain loads produced 2,019 fps.

The ADI load of 49 grains with the 250 grain projectile looks well above factory to me. Gil stopped at 44.5 grains of IMR 4064 with the 250 grain Nosler AB for 2,112 fps. The AB projectiles are harder and run the pressures up faster than the softer projectiles. Gil also found that 8 x 57 cases had necks to thick for his chamber when necked up to 9.3. Something to be aware of. This data and more may be available on loaddata.com. They have a free access section as well as a subscriber section.
Regards Grandpamac.
