A few more small steps forward over the past week. Finally learned how to turn 375 Ruger Basic cases into 404 Rugers using the 375 Ruger & 404 Jeffery FS dies. Lost a couple of cases along the way.
And now learning to stamp the correct marking on the case heads - still have a way to go there to get the right feel and alignment. Hope to have some shootable rounds next weekend, unless work keeps getting in the way.
First correctly (?) headstamped case
