I worked up a nice 38-44 load using Handloader (Oct 2016) data using Keith 358429 bullet, Power Pistol and CCI500 primers. I tested the load in a Ruger Blackhawk 4 5/8 inch revolver. The load I settled on was not only accurate, but chronographed at approx. 1,000 fps (993 fps avg) It is not the max. load in Handloader for this bullet and powder combination, but was the most accurate in my Ruger.
I use this load only in my Ruger. I found that the 358429 performs better at +P through 38-44 levels. Great working load with adequate power and accuracy for my shooting pleasure.
