Seating Primers

[Ernest T]

Just measured my Lee Universal pin at 0.068". So if your Lapua has a 1.5mm vent, yeah, you will need to find a small pin decapper.

Sucks to get all fancy. ;-)


Perhaps Redding in their infinite wisdom has discovered the need for small decapping pins and have them available for their customers, and if not I would next contact Harrel’s precision and get the correct die.

I think you guys missed this.


I use the Redding die with the small pin now, but I didn't know I had an issue before. I have another couple hundred Lapua cases, I'm glad I didn't use them.

Yes, it appears that I have missed that.

FYI Peterson small rifle primer brass in the Creedmoore calibers takes small decapping pin also.

Redding states their decapping pin is 0.060". That's 1.5mm. That's 2/1000 of a mm fat. Shouldn't upset the vent as much as shown in the first image.

Mine is .057, I measured it.

I ordered the Master Hunter set and it came with two pins that size.

It may seem like symantics but the flash hole is 1.5mm that works out to be .05905. Therefore it would need to be smaller than that dimension to not interfear with the walls of th flashhole...if the european holds their diminsions true ie... manufacturing tolerences. Half my BR brass has had a .0625 pin pushed through it. I am sure many of us had to learn the hard way. It still works the way it is supposed to.

If you use a Primal Rights, do you have to uniform pocket depths? That is a chore but it may be neccesary if one goes that direction. Going to have to go check out and see what they suggest. Did I mention uniforming pockets sucks when doing 100 +or-.

The recommendation is that you do not. This is because cases are held by the top of the rim, so all depth is based on that surface. Uniforming makes things less uniform because it is not based on a machined surface. People who have measured off the rim, find pocket depth to be uniform on best quality brass. That is not me and I forget who told me, but my uniformng tools basically sit idol!

I like a good argument....First off, my targets tell me if My method works. I hand prime
so I can feel the primer bottom out. As for going a bit more ?? I try not too. But if you want
to, hand priming is the way to do it. I've measured enough primers over the years, to know
that even the best vary in thickness. To set a mechanical device and do them all the same
will hurt your accuracy and why most all true bench rest shooters hand prime. I see there
was a mention of Eric Cortina. He's a good shooter and does win (in his game) I see he just
won the nationals. To be straight forward....Eric would get his head handed to him Shooting
short range 100/300 group and score. It's a different reloading game where if you don't
shoot in the minimum of low 2's, you go home.....As I mentioned in an earlier post , I
use a Sinclair hand primer. Not long ago I picked up the 21st Century hand primer that you
can set to seat primers exactly the same depth every time. Well I soon found some primers
were crushing and some were not bottoming out. These were those Federal primers. Checking
thicknesses told me what was going on. All in all, I decreased the amount of fliers I was having
by uniforming and hand priming by feel. That's my method, and it works. I compete, I can't
afford to be sloppy in any area of assembly. I'll save weight sorting primers for another argument
other then to say quite a few of the top IBS and UBR shooters do it.....


EXACT-A-MUNDO! Especially when it’s being sold by a dude that talks the way the Primal guy does & spends the money he does (while making certain he lets us LOWLY Savage bottom-dwellers know how much better of a person he is because of the money he can spend on shooting/reloading equipment), yet has NO big wins backing up his name. Soooo, yeah! I wouldn’t buy a thing from him!

[Dave Hoback]

Get a universal decapper from Lee. A great $13 investment. I keep one on a Lee “C” press.

+1!! Definitely a good buy! I have one usually permanently installed in my old Lee Challenger press. And the other dies in my Dillon.

As for oversize de-capping pins. Why not just chuck it up in a drill and hand turn it down enough to fit? Use backed sandpaper or maybe a Diamond stone against it a bit. No biggie.

Your not a big fan either Robin?

Here's a video of the pin in my Redding full length sizing die sliding into a new Lapua 6.5 CM case with SRP pocket. By the time I bought this die, I'd already unknowingly buggered up the flash holes in my brass.

Im not affected by Brand Loyalty or Disloyalty. I grew up in the days of the verbal Ford Chevy dodge truck wars. We talked plenty of Chit. In the end we were all still good friends. In the grand scheme of things....whatever makes you happy.

David,
As for the GIF, That was Orkans moniker on several forums going way back.

No worries.

What is a good primer pocket reamer that will remove that ring? I have tried to do it with the Lee Case Conditioning tool, but all it seems to do is shine it a little.

[charlie b]

I'd probably just use a small dia drill bit, turned by hand. Would work like a countersink. Go just enough to remove the burr. Even better would be a small center drill.

I don’t want to drill it out, it’s pretty wide and the hole will be even bigger then. I want to shave it down even with the bottom of the pocket. Right now, all the Lee tool is doing is highlighting the ridge.

Don't know about a reamer but the RCBS Primer Pocket Uniformer should do it.

[Stumpkiller]

How about clamping a 1/4" pin-punch or steel rod in a vice, setting the case over it, and and (lightly) tapping the ring flush with a 1/8" pin-punch. That will also bring you back closer to a small vent (you may need a small drill-bit in a pin vice to even them up to the proper diameter).

[charlie b]

^^this might even be better as you can even up your flash holes.

Sorry, not enough info on the other. Use the center drill like a deburr tool. Just twist it until the flashing is gone.
