The 8X57R is simply a duplicate of the old 360 Nitro Express No2 which was first loaded with black powder, and later with somkeless! The factory loads only developed about 1800 fps,with a 196 gr bullet, and rifles made for this round should be used with caution when useing smokeless powder, and jacketed bullets.

Which isn't quite true. The 8x57R/360 is based on the early British .360 2-1/4" BPE case, which also spawned a zillion other cartridges including the 9,3x72R and even the .30-30 family. The .360 No.2 NE is a much larger case based on the .450 3-1/4" and was loaded only with smokeless.

There was an article in the "Handloader" magazine years ago that listed some loads for the 8x57R/360; I ought to scan that one and post it somewhere as this cartridge does come up fairly often.

Bprsteve, you are absolutely right, and I thought of that in the middle of the night, but didn't have time to edit my post. You know how it is when one passes the old timers test! I will edit it now!
