RCBS small base 300 blk
Quote from Reloader on January 20, 2021, 12:14 amI have been loading my 300 blk on a chucker for years. I’m using the rcbs small base dies which requires me to set the die at the shell plate. In order to set the die to the proper location to form the brass correctly on my new 550, I have no threads showing to lock the die in place with the lock ring. What am I missing here? I have not read any other complaints about this. Any help would be greatly appreciated. If I’m missing something simple, take it easy on me.
Thanks

My thoughts are to drill and tap the tool head and install an allen screw to secure the die. I just don’t understand how I’m the only person with this problem.

I can't visualize it in the little walnut I call a brain

Quote from kennyarndty on June 17, 2023, 3:31 amHere you go. This is my setup using a Mark 7 trimmer. I also have a Dillon 1200 but for some reason I can't get the vacuum manifold to work right when I'm trimming 300BLK brass. I use a mini chop saw to remove most of a 223 brass and then use the trimmer to do a final to size trim. Note on picture 2 that the lock ring is installed on the bottom of the tool head. As you noted there aren't enough threads at the top of the tool head. The Dillon lock ring is smaller than any other's I've used. Picture 1 shows the location of the second resizing die. It's an RCBS Small Base Sizer for the 300 BLK caliber. I also prefer a Small Base die for .223/5.56

This works with the RT1200 as well, and includes a modified exhaust chip manifold.
