Rick,
You need to dump that RCBS single stage press. Get a Dillon RL450. Use your dies in it. Prep your cases ahead of time. Then you can knock them right out. Every pull of the handle and out comes a loaded round. I have mine set up for 30.06 because I had a bunch of cases to do. I'm going to change it to .300 blackout soon. Once I get my suppressor approved. I also have a RCBS turret press. I have another set of 7.7 dies in it. All are where they should be. When I do 7.7 cases I just swing the turret wheel over to the next die. One die is a universal decapper. So all cases get decapped in that die. I never have to adjust dies.
