I have a RC IV, it came with a auto feeder arm , but when I load for precision I use a RCBS hand held primer. Now that I am getting to reloading for 5.56, I want a faster way to prime. As you all know, big hands makes it a pain in the ass to grab a small rifle primer, make sure it's right side up, place it to the cup, which is right next to the front support beam.
I have done some research, and found what I think will work, but I can't seem to get definitive information on the RCBS 9358. Does anyone know if this unit will fit on mount correctly RC IV? Or, have you found a better, faster way to prime using a RC IV? |
 Here is my primer feed I use on my Rockchucker II. Couldn't find RCBS 9358 on RCBS's website, can you post a link? The Rockchucker IV does not appear to have the slot necessary to mount a primer feeder. I think they went away from priming on this press, but never having one, I don't know for sure. You may want to try the used market, I have bought several Rockchucker II's on the used market and later sold to guys I taught to reload.  Another option is RCBS's bench primer, about $90 new. A little bit more than what you would pay for a used Rockchucker II. |

If we're being pedantic, he asked for a way to prime on an RCIV, and you (correctly so far as I know) pointed out that it doesn't have a cutout then recommended a separate bench primer and a separate press, which, given the price, is less useful if they performed objectively the same. He specifically asked for a method to work with a IV, and didn't specify what brand, provided it worked with his RCBS press. I like the RC2 priming system best if I'm priming on a single stage as well, not sure why they moved away from it. Does this gizmo work? Pretty poor reviews regardless. |

Ok guys, actually you both are correct, and thank you for the replies. I already have a hand held, not too bad to use if loading my precise rounds, but for a more mas produced amount a auto feeder would be better.
Yes, the RCBS auto loader isn't exactly loved out there, but there have been a few that got it to work. It's been out long enough that I hope they have improved it. The reason I ask about the mounting is because on my press, it has a mounting surface face that is parallel to the charging handle. 
This one in the link shows a mounting screw perpendicular to he charging handle. 
But I have seen it mounted on my style of press in a few pictures, but they are not closeups, so I cannot be sure what press it is. As far as the bench top version, that is going to add more steps to the process. Thanks to all, keep the suggestions coming! |

The bench top auto priming tool, unless you are using a case kicker, does not really add a step. Remove the case from the press and place it on the priming tool, prime, then set aside. My dad primed on the Rockchucker for a while until he bought the auto tool in the early '70s. Because of the improved feel he never primed on the press again. I still used that same tool now.
ETA: that pic is the priming assembly for the turret press. |

Trust me, if the round and primer are already in the press, taking it out, putting it in a different press, then performing the priming function, it adds more steps. This is a bad picture I know, but all the better ones are not as close. But, it specifically shows it in my press, which is not a turret style press.

You should buy that part, install it on your press, then report back. P.S. You should ask yourself, "If priming on the press is so wonderful, then why doesn't RCBS include an auto loading priming system on their flagship single stage press? |

Hey guy, don't get boo boo lip.
1) You should have given more thought to your response. It only makes sense that if you have to take it and install it it another press, and then prime that you are adding at least two steps. 2) Get better at being able to tell the difference between a turret press and a non-turret press. As far as a better feel for the hand held version, yes, you get a direct feel for the process. But, once you learn the feel for it when using a press to prime, you will be just as accurate. Don't be a smart ass and no one will hurt your feelings next time.... |

As OP, let me take care of the rude comments. Your goal should be to not get your thread locked. Don't know if you noticed, but I posted this in your other thread also. You have a problem with a post, send me an IM. Just so everyone's clear, here are the rules for posting in this forum, SPECIFIC TO THE TECH FORUMS. The tech forums (Ar15,AK47,Handgun,Armory,Training,Outdoors) are more "formal" and actions permitted in the GD forum aren't permitted there. These forums are there to share information and as a result, trolling, heated arguments,insulting others,etc won't be ignored. |

I agree, but what is the reasoning for his response? It's just rude when someone jumps in and start acting that way. The posting was going in a good direction, and starting to take shape. This is my point of view: 1.People were trying to help and it seemed you didn't like the answers you were getting. 2. Saying "Trust me" is rude and condescending. As if the person you are speaking to does not know enough and that you are the SME. 3. Not sure what your line is, but I have years of experience in manufacturing and have used both processes( which I doubt you have) I can assure you that I know all about "steps". You can prime faster with the auto tool than the press. 4. The lip comment was rude. 5. I won't comment further in your threads. Best of luck in your endeavors. |

Back to the original question;
I used to do what I thought was "high volume" loading on my RC a long time ago, and I never had a problem with the included primer feeder that came with it. I have NEVER been able to find out why RCBS took priming capability away from the earlier Rockchuckers. But here we are today with new Rockchuckers not set up for priming like the earlier ones, so if I had a new RC, I wouldn't fight it. I'd just get one of the separate priming mechanisms and not try to do it at all on the RC. On the other hand, by the time you go through all the additional expense, you could almost pay for a progressive and actually DO higher volume loading, and .223 is certainly a round that typically qualifies for higher volume loading. I wish I knew why RCBS took away the priming arm from the new Rockchuckers because it always worked well for me, and still does on smaller runs that I do on the Rockchucker (all my 250+ size runs are done on the LnL AP). However, if a person wants to stay with a single stage and is married to the (newer) RCBS RC, then the bench mounted RCBS primer setup would be the closest to having the older RC with the priming arm. As an aside, I still don't understand how some people believe that they get better "feel" with a handheld primer as opposed to doing it on a press. Even with the high leverage, I still feel very small differences (when they happen) from one primer press to the next, even in the progressive which is one situation you wouldn't think would allow that. |

I wish I knew why they took them away as well, I can see how either the stock one that came with my press, or the 9358 would cut down on time and fatigue, no matter who says otherwise. I have hand loaded primers since I began to reload, nothing else. But, that was for precise, small amount loading only, not for what I am about to do. I think I ma going to just buy the 9358 and see what happens, it's less than $50.00, and I can get it local. I am of the same opinion as well about a hand primer vs press type primer. I have loaded a few on my buddies presses (Dilon XL650 & 1050), you can feel the set of the primer through the handle if you do it right. I just don't know if I want to spend the $1,200.00 plus right now. If I was making money at loading, then yes, but for just the two of us, not so much. I have two single stage presses, so I can set one up for de-capping and sizing, and the other for the rest. the only draw back is of coarse, when I want to switch calibers, I have to switch dies. The depths don't change, just set your lock rings correctly, and seat them each time, once they are set, there is no reason to touch them again. Thanks for the reply.... |

I have an RCBS turret press. The priming system was included with the press. It looks like the same one that was posted above but without the lower piece. It worked fine on the turret press.
I bought a Hornady LnL AP and the priming system was giving me fits. I bought the RCBS bench primer to prime before going in the progressive. I have since fixed the Hornady and am very happy with it. I love the bench mounted primer. I think it is much faster than priming on a single stage press. I have carpal tunnel so squeeze devices hurt my hands. |

I think that most of us, no matter which brand of progressive we buy, all have similar experiences tweaking our progressives. They are all, after all, glorified Rube Goldberg machines if you think about it. I also had an auto priming issue when my LnL was new, but patience and checking it for proper adjustment yielded a perfectly operating mechanism with the only occasional mis-step caused by spilled powder (which I solved by making other tweaks to the timing pawls). I would recommend to anyone wanting to get into higher volume reloading to go ahead and make the step to a progressive. They all need tweaks and good maintenance, but that's their nature because of how many steps they have to perform at the same time. Just be patient and get to know your progressive and it will jump through hoops for you. I had been a Rockchucker user for over thirty years, but when I finally bought my LnL AP, I couldn't figure out why I waited so long to go progressive. So in the end, ANY auto primer "can be" problematic to use, but if a person is going to use one and they want to go to higher volume loading, then it's not really that expensive to spend maybe $400 on a LnL and actually DO higher volume reloading. |

I know you are looking for an on-press option bu I gave up on trying to make "On-Press-Priming" work.
There was never any way to make it efficient or easy. I have a Rock Chucker Supreme with the little flip over arm and I have an RCBS RS with the feeder and tube while the flip arm is simple and effective it is slow and I had a hard time getting the primers into the cup correctly AND I could NOT use it with my Case-Kicker at all. I was never really able to the RS primer feed to work quite right so I gave up on it quickly since I already had a hand primer by the time I got that used. I went with the RCBS universal hand primer and actually really like it a lot. No shell holders to mess with and changing from large to small is a piece of cake. http://www.midwayusa.com/product/319794/rcbs-universal-hand-priming-tool?cm_vc=ProductFinding I too have big hands and once I got the hang of how it works I can cruise through 500-1000 in no time. The only thing I don't care for on it is the way the primers have to be flipped AFTER the lid is on it but that is a minor quibble. |
Thanks for the input, as long as it is not negative (which it wasn't) it can still be useful. Like I said before, I have a hand primer, I was just hoping that by going with a automated press version it would be faster than my bear claws vs the primers fight. But, from what I have so far from people like you giving good information, maybe I will just stick with what I have. This is very similar to the one I currently use, but the ram is different. There is nothing wrong with it, but, after a straight 500 rounds or so, I can see it being a issue. I will try to use the one that came with the press first, then go to the tube fed one. For less than $50.00, if I don't like it, I can sell it for a slight loss and be good with knowing I tried. Thanks again for the info..
