Join the contest SubscribeFor controlling seating depths I like my 21st Century priming tool and I also have the Frankford Arsenal tool that works almost as nice, just not as well built.What is everyone’s go to primer seater besides the primal cps?
old retired guy with limited funds and severe arthritis here. without dropping the big bucks on the primal CPS primer seater, is this Hollands modified RCBS about the only other way to go for a precise bench mounted primer press? anyone have experience with other quality bench systems? there doesn't seem to be a lot of bench mounted options out there.https://www.hollandguns.com/m7/H-PPS-CU--hollands-perfect-primer-seater-complete-unit.html

Multiple threads on this and the short answer is no. It's the RCBS bench tool (I've had mine for decades); if you add the Holland, you're close enough to jump up to the CPS. So RCBS it is for most people with limited funds allocated to primer seatingold retired guy with limited funds and severe arthritis here. without dropping the big bucks on the primal CPS primer seater, is this Hollands modified RCBS about the only other way to go for a precise bench mounted primer press? anyone have experience with other quality bench systems? there doesn't seem to be a lot of bench mounted options out there.
I’m relatively new to reloading, so take this with a grain of salt.old retired guy with limited funds and severe arthritis here. without dropping the big bucks on the primal CPS primer seater, is this Hollands modified RCBS about the only other way to go for a precise bench mounted primer press? anyone have experience with other quality bench systems? there doesn't seem to be a lot of bench mounted options out there.
Well if you have arthritis forget the hand priming, like stated above RCBS bench priming tool, the other bench modified RCBS systems are getting into CPS primer cost.old retired guy with limited funds and severe arthritis here. without dropping the big bucks on the primal CPS primer seater, is this Hollands modified RCBS about the only other way to go for a precise bench mounted primer press? anyone have experience with other quality bench systems? there doesn't seem to be a lot of bench mounted options out there.
I ended up getting the RCBS ram prime as well, but gave shims a try instead of the PMA micro adjust tool. So this solution costs about $60 ($33 for ram prime, and $25 for shims). Only done about 30 cases so far, but except for one that got seated a little deep (.0095), it's held within .0005". I think once I get technique down it will be just fine. How's your consistency with the PMA tool?Thanks for all your advice. This is what I ended up doing. It’s an RCBS ram prime with a PMA tools micro die adjuster. It is super easy to dial in and very repeatable. No auto feed , so it’s slow. Easy on the wallet though.

Thanks! I saw that Lee also has a ram prime that's even a little bit cheaper, but looks a bit beefier..Pretty slick set up JC. I don't have a problem with consistency once the die is set up, while using the PMA die ring. Once it's adjusted and locked down, it provides very consistent results. The shims you're using will probably be a little faster to use for set up. The primers I have measured once the PMA die ring was adjusted and locked down were all within .0005" seated depth, so accurate enough for me! Once the die is locked down, it is pretty much out of the equation, so repeatability is all on the press, shell holders, and the ram prime die. Might have to give the shims a try though! Seems easy enough. Thanks for the tip, and great video!
Just checked out the Lee unit. Cheaper and beefier!Thanks! I saw that Lee also has a ram prime that's even a little bit cheaper, but looks a bit beefier..
Doing some more seating today.. it's even more better if you have the Redding competition shell holders! Just loaded some 223 and they were all .006-.0065" (could have gone deeper, but wanted to try this depth out first).Just checked out the Lee unit. Cheaper and beefier!

Dumb this down for me please...it's even more better if you have the Redding competition shell holders!
The competition shell holders change the height of the case in the shell holder by .002".. The set has a .002, .004, .006, .008. and .010" shell holder. So you can set up the ram prime with shims so that you seat the primer say .004 below flush using the .002" shell holder (it's the thickest base one). Then to go deeper you can go to the .004" shell holder to get to .006" below flush.. etc.. so keep going up in shell holder from .002" till you get where you want. If you want to refine it up or down .001" then change the thickness of the shim.Dumb this down for me please...
^^^^^This. Just got one of these. Very fast and easy to use.Frankford Arsenal Perfect Hand Primer, it's consistent, repeatable, and fast, and has foolproof adjustable seating depth too.
I've done ~10,000+ cases with one over the last couple of years and it still looks new and works like the day I got it (for like 70 bucks).
Interesting.. I have comp shell holders for .308 and .223The competition shell holders change the height of the case in the shell holder by .002"..

The comp shell holders work both ways (on a rockchucker anyway). When you put them on the ram of the RC to use for sizing they change how close the sizing die can get to the base of the shell, so work great to control headspace. So you start big at .010", and the lower you go the more it will be sized = more headspace, till you get where you want. They only really make sense if you are making contact/cam-over with shell holder and die.Ok
I was under the impression that the comp shell holder only changed the dimensions from the base to the top of the shell holder
And looked like the ram prime referenced the bottom of the shell holder
But I guess the comp holders must be the same outside dimension and the rim groove pushed down into it then
Now I gotta spend 20 bucks and a month of Sundays experimenting and measuring lol
To provide desirable shellholder-to-die contact during sizing, without excessively setting the case shoulder back, Redding now produces shellholders that are made in increments of .002” deeper than the industry standard. The nominal industry standard depth (dimension X) for shellholders is .125”. The new Competition Shellholder Set includes five shellholders that are deeper than this in increments of .002”. Therefore, the set includes shellholders that are marked +.002, +.004, +.006, +.008 and +.010, which is the amount the shellholder will increase base to shoulder case length and thus decrease shoulder set back and case to chamber headspace. To select the proper shellholder for your particular firearm’s chamber, simply start with the shellholder marked +.010. The shellholder should be adjusted to make firm contact with the bottom of the sizing die during the case sizing operation. Resize a case and try it (unprimed and empty) in the chamber of your firearm. If the empty case does not chamber or chambers with difficulty, switch to the shellholder marked +.008 and repeat the process. Stop at the shellholder that allows the firearm’s action to close freely. Your cases are now being sized properly to fit your chamber with a minimum amount of headspace
Actually we're both right... measured it with a Starrett micrometer.... I would post pics if I could (if you haven't gathered by now, I'm cheap)JCCinOHIO you dont know how competition shellholder works and how priming is done.
Competition shellholders have SAME base dimension, just upper portion is higher:
In the Redding link, the dimension of 'X' is changed by raising or lowering the bottom line
Top of the shell holder is the top.. doesn't change.. The other line is where the base of the case sits.. that line goes up or down. So if you move the face of the case down, without moving the top.. you size less case. Assuming contact and cam-over.i dont think so. X is changing, bottom is the same ?
