I'm a new bullet swager of about 6 mo. I've been making .224's out of RF cases. I'm still working on my technique & getting all my equipment & accessories worked out & I'm really enjoying my new hobby. I don't have a shaker yet - still looking.
I was piddling around in my shop when I discovered that a de-rimmed RF case fits perfectly in a peg-board hole. So I before I knew it, I had several boards cut-out & glued to the bottom of my reloading blocks. Now I know this is not high production but it certainly is handy if you are making a small batch of experimental bullets. The cases stand tall in the 1/8" peg board & with a little lube on your fingers you can twirl them as you pick them up.
Just FWIW....
