Over the years, I developed a preference to prime on press with either the APS priming tool, or the priming capability of the press. I went through a few of those as well, the primer slide on the Big Boss worked very well.
Of those tools, I kept the RCBS APS press mounted primer, because it was the only one that could control seating depth. It has the annoying habit of jamming up every once in a while, needing to be disassembled and re-assembled [ years later I still haven't figured out why ], so I kept a lookout for either a second one, or another priming tool that could control seating depth.
I considered the RCBS bench prime tool, but looking at the vidoes, I realised that the primer tube flopping around would just irritate me, and there is no hard stop for primer seating depth.
I also considered a Lee Bench prime, but it has no hard stop for primer seating depth.
I could probably drill and tap something into either of those, but I remembered the Lee Ram prime I use to have but never used, and thought it would not be a bad idea to get another one and try it out.
It works very well. I keep a dedicated Lyman Spartan with the Ram prime set to the seating depth I want. It's not the fastest, but every primer goes in right way up and exactly right. An oversize pair of tweezers prevents fumbling fingers from mis-seating and dropping primers.
