Just a suggestion - I have an old RCBS Rockchucker. It has to be the worst at handling spent primers. I solved my problem with the cheapest Lee bench press they make and a universal die to punch out primers with. It works real well, rarely do I get a primer on the floor and I use it for every thing. I did have to do some filing around the primer hole to smooth it up, because it would spit one out on the floor once in a while. It sets right next to my RCBS press. I not only use it for punching out primers, I use it with a bullet puller too.
