I just reloaded a box of ammo for 45acp. I used 6.0 grains of unique. My son took the ammo and shot it. He said that the loads seemed a little hot with the recoil and muzzle flash. I am using 230 grain lead round nose. I am looking for a mild load that I can shoot in my 4586 semi and 1917 pistol. I really like using unique in my 357 so I have a little left. I purchased the load book for the 45acp and these are my first reloads for this cartridge. The smallest load I see for a mild round is around 5.5 grains. I wish I was a lot more knowledgable on the use of gunpowder but since I am not here I am. I use 4.6 grains in 38special with a 158 grain LSWC. Would the 4.6 grain work in the 45 auto and be able to function? I know a lot of questions in one thread but I need to know.

Thank you
Charlie
