Anyone here using this press? I got a used one that I think might be missing some parts. When depriming the spent primers go everywhere. Is there something that should contain them? Also the shellholder slips right in & out. Real easy to pull brass & shellholder out of the press together. It has holes that look like maybe a set screw is used to hold the shellholder in. Looking for someone that has a complete one to steer me towards what I might be missing on mine. Thanks.
