Okay, that's not much but it shouldn't be. So, let's try to figger out why; it's possible the pockets are too shallow OR your current batch of primers may be too tall. (IF so, you should let the maker know, an email should do it.)

First, try another brand of case (of any caliber) to see if a different pocket will work right with the same box of primers. IF so, it's the pockets.

If not, decap and try another primer (of any brand) to see if they will work in the same pockets. If so, it's the primers.

If they still won't go, decap one of the live primers that has been seated as deeply as you normally would, and look inside. IF it went all the way down, the anvil legs should be flush with the mouth of the primer cup. Measure it's height vs. the depth of the pockets to see if there is a meaningful difference. I actually have the normal depth specifications of primer pockets somewhere ... but I can't find it so I may as well NOT have it... but it's around .122-.125 inch, IF I remember correctly.

Jim,
Thanks for your input. I will definitely give it a try. I'm sending you a PM.

Steve

Re: Who makes the best hand priming tool?

If your primer does not go into the primer pocket to flush or lower, the problem is the case, not the primer!!! Primers are made to much greater tolerances than are cases.

Benchrest shooters and other shooters who are inteested in maximum accuracy always ream the primer pockets with a primer pocket reamer (uniformer). This tool will ream the pocket to the correct depth and remove the rounded bottom edge in the pocket which can cause the primer to not completely set to the correct depth. These tools cost about $10 or so.

During the original case forming, the flash hole is punched and sometimes leaves a burr inside the case. You can buy a deburring tool or just use a drill bit of the correct caliber to remove the burr.

Note: The uniforming and deburring only needs to be done once.

I really like the Forster Coaxial Primer tool. Excellent feel, very fast, no sore thumb. The Coaxial shell holder and easily be set to hold any case. Most importantly, if this seater won't seat a primer in a case it will most likely will not be seated by any other primer seater. It will easily seat a primer in the very tight pocketed Norma cases. IMHO.

The press mounted feature is identical to the bench mounted unit. My press uses the older style shell holders, rather the currently offered jaws. Works well, and is very consistent. No matter how hard or how slowly you seat the primers they always are about .005" below the face of the case.

I like the fact that the primer rod does not have restricted travel distance like many other designs. This insures the the primer is seated fully do you fell the primer hitting the base of the cases pocket, not the end of the rods travel distance.

Re: Who makes the best hand priming tool?

Have to agree with JMAY2174....The primer pocket uniformer will clean up the edges and give you a uniform pocket depth with clean edges...After that you shouldn't see any more protrusions...Todays massed produced components are far from perfect....Thing of it is that your brass may have had shallow pockets with overly large bottom radius and the primer cups were long....The uniformer (I like the Redding) will get you deep enough to clear those long cupped primers...

Just measured a half a dozen Fed 210s...That day's manufacturing practices put the cups at anywhere from .123 to .127!......Setting primers with some tools will help you put them equal distance from the case head...But if you want the same "crush" each time your primer strike will obviously change....

I have used mostly a press for seating for nearing 48 years now...and the "feel" you develop with all that leverage will tell you all about loose pockets, tight pockets, tight & loose brands of primers.....With a press you have to be careful about overseating...The uniformed primer pockets should let you feel the bottom easily and any "crush" you add after that is with the same "feel" you develop with any primer tool....When in doubt measure the primer depth when your done....Keep track of the depths (below the case head) and try to come up with a logical synopsis of what those depth changes cause...You most likely won't be able to correlate anything with a little inconsistency....Proof will be on both the Chrony and the target...

Good Shooting,
Randy

Re: Who makes the best hand priming tool?

Randy, this is where the indicated K&M set's itself apart from all other priming tools. With it, I set exact crush on every single primer seated.
You have a good point about potential striking distance variance with this, but it can be accounted for with another measure.

To begin, uniform every pocket(get em all the same depth).
Measure out & match needed primers by unseated height. Throw departed away.
Zero the K&M indicator on each primer to each individual pocket(which should be about nothing of an adjustment by that point).
Seat that primer in it's pocket to .002" crush as indicated.
They are the same height from the casehead, AND preloading the pellet as recommended.
Now mind your headspace.

This is impossible to achieve through feel, I don't care how much you spend or how shiny or red communist any other tool is. It must be measured or it isn't happening(not even close).
Only the K&M(Creighton Audette design) is capable right now & it's actually a damn good tool regardless.
I am purely impressed with the intelligence behind it's design. And you might notice that while other priming tools are perpetually copied, every market is shared these days, the indicated K&M still stands alone.
