Definitely. I crimped these (taper) on my single stage for the test. That shell holder sometimes gets debris. I try to watch that every case inserts completely for sizing, neck expand, etc. But junk gets in there.
The RCBS mandrel would mean taking the die apart. If I get time, I'll do it. I'd like to see if there's visible wear anyway. I've sure ran well over 50k pieces through it by now.
