I don't much care how many caliber changes....because both my RCBS presses are extremely easy to change calibers on....
for me it's the # of pulls on the handle that I feel....but then I'm oldish.
The O.P. made his decision, hopefully the best one for him, and I heartily congratulate him on entering the hobby........this post is for everyone else who may be looking at RCBS's new offerings and deserve correct info on them.
And drain smith it's just a little correction
.......RCBS Pro Chuckers 5 & 7 do have a tube case feeder, a pistol bullet feeder/electric collator (left over from Pro 2000 days), and a brand new tube rifle bullet feeder (all are options). But you are nearly right, no collators with the RCBS name on them except for the old one for the pistol bullet feeder.
Seems RCBS isn't ready to risk the development costs on new collators for Pro Chuckers yet: 1.) knowing that those available from others, Hornady, Dillon, Mr. Bullet Feeder work fine on the new Pro Chuckers, for those who think they have to have one for heavy production. 2.) Waiting on the new Pro Chucker line of presses to be successful.
In my experience with the Pro Chuckers, the case feeder needed a little $5 mod. Works perfect now. Dillon's 650 case feeder is super. It has been around a good while and any flaws are ancient history. It also comes standard with a 650 and for good reason.....without it there's an ergonomic problem not found in either Hornady or RCBS progressives. Feeding by hand with the same hand you stroke the press handle with. No problem with the built-in case feeder......but the collator is an option there too.
RCBS's pistol bullet feeder was made for the old Pro 2000 and works, but not so good with lead.....similar in design to Hornady's.....I use Hornady's because it was available before RCBS came out with theirs. Yup, collator and all for both my Pro 2000 and Pro Chucker 7.
The New RCBS Tube Rifle Bullet Feeder for Pro Chuckers (new last January)....is awesome...as good as "Mister Bullet Feeder's.........
but, its a tube feeder......no electric collator....yet.
If you think you have to have collators? I recommend Dillon's case collator highly for any progressive, and Mr. Bullet Feeders bullet collators, for any progressive. But as fast as they work....they aren't so fast when you want to change calibers.
Tube feeders are faster and way easier to use and
way easier on the pocket book. I find it a royal PIA to have to change bullet feeder parts and settings every time I change calibers. But I would buy them for sure if I had multiple presses set up each for one caliber.
