RCBS Rock Chucker Supreme Spent Primer Device

I don't remember if it was here or on another forum, but there is an easy fix for the plastic catcher to actually work. Use some rolled up inside out duct tape between the back of the catcher and the frame of the press. With a little fiddling as to exact thickness, 95% instead of half of the spent primers will actually wind up in the trays on either side of the ram.
 
Mine seems good for 95% of them if I push the catcher toward the ram each stroke or two. It is a pain but the darn press is apparently perfectly concentric - every die I screw into it coughs up concentrically sized brass and straight bullet seating (with match seating dies). With or without o-rings under the locking collars, it just works.
That or my concentricity gauge needle is glued in place...:)

Mine as well. I measured it every way I could come up with and the darn thing is just plain square, which is all you can ask a press to do. My concentricity gage basically collects dust at this point because every time I use it it says the same thing.
 
At times my RC IV would spit a spent primer out the slot for the priming arm. Since I only use a hand or bench mounted priming tool I cut a piece of 5/16" key stock then filed it down just enough for a interference press fit in the slot ( .26x" something). Now they have nowhere else to go but into the catch tray. I haven't had to vaccum primer one off the carpet since.

I use my RC2 for bullet seating only, sometimes neck sizing. Everything else about it ticks me off. I use my Lee Classic for sizing and decapping. The primer catcher and primer seating operations are just not good. The press is great for seating, however.
 
I just put a small piece of foam rubber behind the plastic part and it pushes the plastic part forward onto the ram perfectly
 
I use 3M electrical tape. I started with black and then went to green. I use the tape to reduce the gap between the catcher and press frame. The one thing I do not do is complain about something I can fix. Seems it always happens when a Lee fan uses the Rock Chucker, they loose one primer and then spend the rest of their life complaining about it. I tape the catcher to the press by going around the catcher and frame. I believe the black tape looked better.

I have two pieces of tape on mine. At the very bottom of the catcher near the press frame I put a piece of duct tape to allow more of a "cup" to hold the spent primers. On the back of the primer tray (or outside the larger circumference) I put a piece of clear packaging tape to block any primers from flying over the side. Works good now to do the catching. I also use a full size coffee can to slide up around the bottom of the press and handle to catch the primers as I loosen the tray to empty it. If I said I contained 95% I would be stretching the truth. An honest 90% is more like it, but I size 2-300 cases in a sitting before emptying the primer catcher. I may have to make myself one of those catchers that have the removable bottle on the end. I have seen them a couple of times, but have not taken time myself to make one.

Have yet to find a press or piece of reloading equipment that couldn't be modified or supplemented to go faster, safer, cleaner, more fool proof, etc. Someone always has an idea for making improvements.

I'm doing a homemade case kicker for my Rockchucker and trying to deflect the primers so they'll go into a tube then into jar or bottle. I'm doing this with anything I can find around the house without having to buy anything. Necessity is the mother of invention.
 
Point taken Guffey, but why do you have to be so negative? The aim is to provide information, not sarcasm.

I believe the black tape looked better.

I suggested 3M, the type of tape is a reloaders option; then I did not insist they use black and or green. The green tape keeps everything green. I pulled down 450 Magnum 257 Wheatherby cases + close to that many 7mm Remington mags; I did not chase down one primer, I did not test the primers. The ammo was loaded 45 years ago; most of the ammo would have fired, I saved the cases.

This is a problem? I put mine on and take it off all the time. The lil plastic keeper departed decades ago. My press is an original RC.. I place the catcher on for de-priming and take it off the rest of the time. Just slide it on and slide it off. The thing gets in the way the rest of the time.. I still lose maybe 10% to the floor. Every once in a while I clean it up. I also place a small garbage can under the press. Still lose em..
 
I almost view the PrimerChucker as endearing. It's been how many decades now and they haven't designed a press that doesn't toss primers all over my basement? Every new iteration of the press continues to assume that we'll use the press to prime, and that catching spent primers is a "nice to have".

Any sane person would design a press where you assume that the user will prime off the press and that catching primers was a significant positive attribute, not an afterthought. Yet it continues...
 
"The one thing I do not do is complain about something I can fix.

Not my words, these are a direct quote from your post above Mr. guffey, your point could have been made without the verbose hyperbole.

Punching primers from crimped primer pockets can be tuff on primer punch assembles. I punched thousands of primers from military cases with total disregard as to where they went. And then I had to fly from Newark to DFW. When going through the inspection station the inspectors asked 4 passengers ahead of me to remove their shoes. Out of sympathy I removed my shoes; what a surprise. My rubber soled shoes were covered with little 'O's', an inspector asked me what the little 'O' were for. I said knobblies for ice and snow grip. The 4 passengers in front of me were from India; they were not happy but thought it was amusing I joined them.
