Yes, Mike, I had my 366408 shortened back in the late 60s or early 70s. Turned out about 185 grains. Used it in several 9.3x72R drillings and a beautiful Sempert and Krieghoff kipplauf and even a 9.3x82R bolt and a 360 2 1/4 Purdey double. Unfortunately, all gone now. I still have a good supply of 200 grain Norma and 193 grain RWS jacketed for the 9.3x72R. I have never tried them in my 9.3x57 Mauser or my 9.3x74R although I did try some 250 grain 366408 bullets I had cast in the pre shortened mould in the 9.3x74R with good results. My current small 9.3s are 9.3x57R (360) Husqvarnas, a combo and a 33 single. For these I had two moulds made up by Tom at Accurate, the 170 and 200 I mentioned previously. The Huskies have a very slow twist. The 9.3x57R (360) rounds are loaded in my old 9.3x72R RCBS dies. Of course they seldom if ever need a full length resize but I only size down to just above the web anyway. I use 9.3x72R brass by Norma and DWM to make the 9.3x57R (360). My standard cast bullet alloy for 1200 -1500 fps is 1 to 20 but I might go to 1 to 16 in rifles where I might be seeing 1600-1700 fps. Commercial bullets that claim hard probably use antimony to get there and oddly that might give problems with leading in some rifles. The only bullets I cast hard are some linotype ones for the 22 Hornet which I may not have needed to but I was given the linotype and that was the only use I could think of for it. No lead will be too hard for your barrel but it may not give the best results. The factory jacketed bullets for the 9.3x72R were soft metal, copper or gilding metal, to be kind on the older barrels.
