I went out this morning to try out some .357 handloads that I pu together last night. I was using Winchester cases, Winchester small pistol primers, Remington 158gr. SJHP's and 14.1 grains of 2400 with a light crimp. I was shooting these out of my 6.5 inch stainless Blackhawk. I was also using a Pro-Digital chonograph to chrono the loads. The velocities were optained by shooting a ten round string approx ten feet from the barrel. Here they are.
Hi-1429 fps
Lo-1359 fps
Avg-1393 fps
Es-70 fps
Sd-24 fps
There were no signs of overpressure. The primers were rounded and extraction was easy with no sticky cases. Recoil was manageable and the report wasn't very loud at all. There were litterally no signs of unburnt powder or residue on the gun. My Lee manual calls for 14.1 grains as a starting charge with 1436 fps being what was listed. Where to go from here? From what I saw from lack of signs of overpressure, I think I have room to go up a little. Will my crimp or should I increase it a little when going up with a higher powder charge?
Thanks, Flip.
