Anyone who has an RCBS IV Supreme press will know that the supplied primer catcher is less than perfect.

I've designed and 3D printed an upgraded version. This only fits the RCBS IV press. It just takes a minute to fit and the kit comes complete with : Primer catcher, 300mm clear hose, Hose bung, magnetic front insert, magnetic rear insert, cable tie and locating screws.

Complete kit is £22 including postage to UK.

PM me for more information if interested.

I have a similar system and it is excellent! This version is cheaper than the one I got, would've have bought this if I hadn't bought a different one a couple of weeks ago!

The front magnetic insert, are you happy to sell this on its own? That's the one bit that I'm missing to prevent primers popping out of the front.

Yes, no problem - PM me your address.

Top man, thank you very much!

Received the items today, talk about fast service! Received the front and back inserts which installed easily. I like that the front insert holds the shell holder in too.

Haven't had a chance to use it yet as I didn't need to decap anything today during my loading session, but I'll give it a go this week. Can't see why it wouldn't work.

Again, thank you very much!

That looks to fit well - Let me know if you have any problems.

I've been depriming a couple of hundred brass cases over the past week using the new setup and have had zero problems! No more primers popping out the front slot, everything falls through the back slot and down the chute into a plastic bag. Excellent stuff!
