A 200 grain lead SG 68 or Elmer Keith's 201 gr.45 acp slug. 5 grains of Bullseye or 4 grains of Vihta Vuori N-310 are generally accurate. The lead should be fairly hard, like the famous Lyman mix. The bullet gets slammed around violently as it leaves the magazine and travels up the ramp into the chamber. Soft lead gets banged up badly and the next thing you know you have a jam. The lubricant should be for low velocity loads. With the right lubricant like Lyman's Ideal lubricant, leading is non-existent.The Lee stuff is good at this as well. A lot of more modern lubricants are made for full power .357 and .44 magnum loads. These are not as effective with these lower pressure, lower velocity loads.
With a 230 grain FMJ. 6 grains of Unique works well. A good taper crimp is critical in all loads as the .45 acp headspaces off the case mouth. Consistent neck tension and bullet pull is critical to good function and accuracy.
I shoot primarily 625 and 1917 revolvers, my pet load for both is simply 5.5 gr Unique behind a 230gr LRN bullet design, brass and primer non specific as this is my plinking load. Its as accurate as anything else I have come up with but is a little light for some pistols.
