I went to the range yesterday and shot my Ruger 44 Stainless 4 5/8s Special with a load of 255 Keiths sized to .431 sitting on a load of 14.5 grains of 2400 and a CCI 300 primer. This thumbuster loves this load and I am assisting in fulfilling it's love as I am loading 200 of this load today. The brass is polishing as I write this.

Shooting off hand with this load the Ruger will put them all in one hole at 50ft and a group of an inch and a half. The group would tighten if I were a better shooter, that potential is in the load and the mechanicals of the gun.
