    Sharps4590,
    The gun was kinda heavy and shot like a big 22! I think I had to make a mainspring for it. Been too long ago!
    I did read there were 5 different cartridges based on the same case separated only by oal- 9.3 x 57, 62, 72, but can’t remember the other two. I think the 72 was the longest.
    It was fun.

    The 9.3 X 82R was the longest. I used it to form the cases for my 9.3 X 75R Nimrod. I can't remember if there was a 5th but I believe you're correct. I'm not certain if the 9.3 X 57RD was the same as the X57R on the X72R case but it was also known as the 360 Express by the British. All are pretty good cartridges, for their intended purpose.

    That .360 Express version was / is of special interest to we, here, who tailor loads for both big and small game as one of only a very few offered that way in factory loads. It came in a load not much more than a .38 Special and one much like a heavy .38-55.

    Ha...I was completely ignorant of the two loads in the 360 Express. I assume by the name the loads were loaded in the British version? I'm more familiar with the German load than the British and I don't recall the Germans loaded two different loads, or at least that different, no?

    Yes, the 360 had a 134 grain at about 1000 (maybe less that many .38 Spc. loads, instead of more) and and a 300 at about 1700. Technically, one was nitro for black and one Nitro Express; but same cartridge, and both fine in any NE rifle.

    Been doing some thinking. Would IMR 4320 work for 9.3x57? I use the heck out of that stuff, and it's burn rate is pretty close to many of the powders that you can find 9.3 data for. Not sure where to start with 4320 though.
