The onset of arthritis, or maybe just the effects of some aging inspired me to look for something that doesn't require repetitive squeezing. I had used a Lee Autoprime and then the RCBS tool (which is much better IMO) for years with great satisfaction, but when loading up to 500 rounds in a sitting it began to bother me. I bought the bench mounted RCBS system and I think it's great. Filling the primer tubes is just a little tedious but not all that objectionable.
Same here, wore out a couple or three of Lee units over the years, and am not a fan of their new style. It got so hard to seat primers with my beat up ol' paws that I started looking for other units, and a friend let me try his bench mounted RCBS- SOLD!
No issues at all , and changing tube sizes is not an issue either, I have a small pick with a very slight curve that I push into the tube to get the primers above the hole, then slide in the cross pin.
