What Priming Tool to Buy

[Mastershot]

nice set up! how are you liking it so far?

Love it, I retired my rock chucker and went with the zero press on black friday sale. I just got my ugly’s setup last week, been playing around with it on dummy loads while checking seating depth.

All my shooting habits can be satisfied with just my RCBS hand primer. Having what's called trigger fingers and a trigger thumb, it gets quite painful anymore lol! Especially when a couple fingers lock closed. Using the other hand to pull them back open really sucks. I'm suppose to be getting set up for surgery before long. Hope the results are good.

I am done with my rcbs hand primers, I have two torn rotator cuffs right now. Just do not have what it takes to prime virgin brass.

I know what you mean, those injections I get in both of mine are a real pain. They help for a while but that's all.

My Forster Coax Press has a primer at the top of it. It seems like a lot of trouble to set up for use. I gave up trying to use it and started using my hand primer.

A dead bear is like a bowl of jello, the rope is so I can drag out the bear or hang myself, whoever gets treed first.

If this thread keeps going you might opt for number two

My hands are giving me more and more problems. I ordered a PCPS and a couple shell holders from Amazon today. It's going to take me a month or so before I can try it out, (still on winter hiatus in Florida away from my equipment). The Primal Rights unit is just too rich for my blood.

I know your pain, I have both trigger fingers and thumb, I have done injections in the past and they helped but lately I can feel it coming back especially my thumb. Hope it works out. Thats the reason I went with the CPS primer tool.

I just got done with my first 200 out of the uglyannealing primer. I’m sold. Stuck it in a Zero and when it hits the bottom of the die, no matter how hard you push, it’s in as far as it goes. Bonus points- you can use same shell plate/holder for priming as pointing bullets.

I don't understand how these precision primer seaters maintain consistency. Primer pocket uniformers baseline is the bottom of the rim, where the name/caliber is imprinted. Don't these precision units base themselves off the top of the rim. Won't variable rim thickness cause inconsistencies unless rim thickness sorting is accomplished? Buying quality brass will mitigate the issue.

There is one hand priming tool that does not index depth off of the front of the rim, the Sinclair. To use it you unscrew the top about a quarter turn, screw it down until the case is tight and then prime. A very good test of depth consistency was done that showed that the Sinclair was the most consistent, a lot more consistent than a $600 bench model. As a personal aside, I do not seat by depth, but rather by feel. I own the Sinclair tool that was used for the test.

@BoydAllen I’m going to throw this out there- measure the rim to bottom of primer pocket measurement. Easy enough with a shellholder and a depth mic down the middle of it. They’re usually stupid consistent.

Think about the shellholder on a “traditional” priming tool- 21st century, rcbs, CPS, etc… Another thing that grabs a case like that is the extractor on your bolt, which holds it in place, especially if you have a spring ejector.

Which is more important to ignition/timing: Case head to primer or primer to the top of the rim?

I have no clue, but it’s one of those things that I wonder about. I use Pandas with the TG ejector, so it’s a moot point to me anyways

I doubt that my Viper's extractor (same extractor style as a Panda) has so tight a clearance on the rims of my cases that it is what determines the position of the case with the bolt is closed, since my bump is usually no more than .001 as compared with the measurement of a case that is a tight fit shoulder to head. BTW for my action the difference between the bolt handle dropping (no ejector, FP assembly removed) and the bolt handle staying where ever I put it, with minimal resistance is only .0005.

I did make kinda a critical mistake that I will need to make a
part 3 to resolve.

After getting a few comments from some folks saying they don't need to pull anywhere near as hard as I was on the primal rights unit to get good consistency, I decided to revisit this by trying a few cases out by just going to the bottom of the stroke with normal force.

By not putting significant amount of force this time, I was coming up about 2 thou short of my old set point. I dialed it 2 clicks deeper and voila, back to my old seating depth setting without the extra effort.

My thought process as to why I believe I was unsuccessful with this before is because the unit was brand new and still had some tolerance stacking that needed to be broken in (primal rights states this)

Overall I still give the win to the ugly/derraco unit due to the price point when it comes to precision.

Carl is working on something to speed up the process with the ugly/derraco unit. Whenever that gets released I will make a part 3 speed test.

My primer die came today. Set it up a tried a few rounds. A Ginex LR primer hasn't got a chance with one of these dies in a T7. Seating is effortless and smooth as butter. Much better than my RCBS Bench Primer.

did you watch my video? i had +/- 0.0005" though with ease.....lapua brass though

even though i highly respect bryan, i feel his assessment of the cps was erroneous. some sort of user error, his consistency numbers were WAY out of line with what that unit is capable of.

Only way his numbers were that bad was if he had the worst lot of brass for rim thickness in history. did you watch my video where i achieved sub +/- 1/2 thou consistency with my cps and ugly pcps?

 

[rijndael]

i achieved sub +/- 1/2 thou consistency with my cps

That's about where I'm at and I've only primed 50 cases or so.

 

[nettle]

.0005" tolerance aside this still the nicest primer tool I have ever used. The depth adjustment certainly doesn't take away form the tool.

Did you watch Bryan's video about how he did his test? IMO he was very thorough. As I have written many times, for me this is all somewhat irrelevant since I seat by feel, and I am pretty sure that most short range shooters do as well. Beyond that, the guys that I tend to copy, at the distances they shoot, shoot the smallest groups in all of shooting.

i didn't watch it in its entirety, but anyone who has lots of use on their primal rights cps can tell you his consistency numbers on the cps are very bad.

Again, so bad that they would be along the line of the worst lot of brass in history......

i'll watch the video again later to be sure i didn't misunderstand anything, maybe i'll make a reply to his video.

So……. I like nice things, I have 2 Sinclair’s and 2 21’st century a K&M and I think I still have one made by Hart. I seat more by feel than anything like Boyd does “He Taught me so to speak” I plan on buying one of these new press mounted systems because I like pretty toys. However you don’t need to spend $200,$300 or $600 to get good results priming. I been staying with my Mom for a few months as she is not doing well and I miss my loading room at my house so last week I brought a extra rcbs chargemaster and Sartorious 505, then Bought a Lnl ap and a Mec Marksmsn off here some other extras from home and I now have a working bench at moms. Today I wanted to load some 22 Hornet up for my grandson to go groundhog hunting, I didn’t want to change out the shell holder in my Sinclair so I ran over town and bought a Lee primer that also mounts on a press, didn’t want it on my Mec so bought a $39 Lee press, it’s there smallest aluminum press, I was amazed at how well it worked and although you couldn’t feel as well as the Sinclair it did still have good feel and in just a couple minutes had 50 cases primed!… I think the press, primer and shell holder was under $80
