Your assessment is right on the money. All is for naught if the primer pocket is not uniform in depth. In reality, all these expensive, high leverage priming tools are just crushing the primer to make the numbers appear impressive to the end user. Think about it........before you dismiss this simple statement. Now you can throw me under the bus! Lol. Carry on.
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.
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.
If this thread keeps going you might opt for number twoA 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.
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.
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.
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.@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
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.
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.
