I asked SAC if the Ugly primer seater would work on the nexus, they said no. They were wrong. It works great. Had to modify the primer tube length (cut it in half) and make an aluminum plate to sit on the nexus shell holder. Am going to make a better plate that has pegs that will insert into the holes in the spare cam discs. This will keep it from moving around, although just the plate on top works fine.

Ugly Primer Seater on SAC nexus press

Will do. Finished the design today and sending specs to my mech engineer friend tomorrow. I'll test it and if all is OK(which I think will be the case) I'll see if he can make a few more. I plan on sending mine to my other machinist to send out for black treatment.
Any updates yet? I’m so curious how the design would work. Also, with cutting down the primer holder, how many are you holding now?
It works great. have seated over 100 primers with no issues. I bought a 6 pack of MJC primers on Amazon for less than one Hornady primer tube. Fits perfect. I havent filled the tube so not sure how many it can hold, but it's about half capacity of a full tube. Below is my rough design for the plate. I've been using just a .12 thickness aluminum plate and it works fine. My final design will be 5/8th thick, and have two brass 6mm long "feet" on the underside of the plate to hold it in place. The feet will just drop into the spare cam pucks on the press. I'm using brass so they don't mar the DLC coating on the pucks. I experimented just drilling a 6mm hole in the aluminum and screwing in a stainless bolt. It worked well, just won't look as nice with the bolt head sticking out the top. I'm waiting on an 80 tooth carbide saw blade to cut this thick plate. Will post pics and update when it's done.

That is so awesome! Really cool to see you doing this for us Nexus guys who are debating to either get off press primer seater or find alternate solution such as what you are doing. Can’t wait to see the end product
