Thank you. I looked at the GSI dies but they don't have a finish die in stock and no word on when they would get one. How does the 2 step process actually work? Do I need 2 trimmers? If I bought the GSI rough die and combined it with the Whidden die would that work for now?

Not new to the site, but new to making 300 blackout. I'm having issues that seem to me to be more operator malfunction than problems with the equipment. I'm using an RT1500 on a 650 Dillon. I have the correct tool head. What is the best process steps to turn the 223 into 300 B/O. How many tool heads need to be committed to the process of making a round and what stations do what task? Here's how I started doing it. I sized the 223 brass in a Dillon 223 sizing die and de-primed. The it cycled to the 1500 to be cut and trimmed and formed to 300. I'm using the Whidden die as the Dillon was not available.. I had the brass shaving issues but I solved a lot of it when I went a 6 horsepower shop-vac. Wow that's loud! Anyway, then I run the cut brass through the deburr stage, and run them all through the Sheridan cutaway case gauge. 99.5% of them plunk in. A few don't. I cull them out. Then I change tool heads and and start to load. Install primers, powder/expand with "C" drop, bullet (220gr Berry's flat bottom), crimp and I have a final product. Again, some don't fit the case gauge. And they won't go into battery. The ones that fit work flawlessly and cycle my 16" barrel no problem. I know I'm doing something wrong but after 3 weeks of trying to sort it out, I'm at a loss. This is why I'm asking. Last night the RT1500 was cutting the brass at an angle. I've changed nothing. No idea why it decided to do that. I have the CSI cutter but haven't installed it yet. Sorry for the lengthy post, but I don't want to go any further without some advice. Oh, I'm using Remington .223 brass no crimp pockets. and I've cut them to 1.350. Thanks............ John
