Marks on primers from seating

[6BRA]

What I've found in my life, is that with alot of these panacea cures to whatever problem that arises, rely heavily on the placebo effect. In that, if you believe it works, it does. The problem with that mindset is that sooner or later the problem appears again.

One way to prove it. Use factory ammo and S...kill yourself to death. LOL. If you think attention to detail doesn't matter. Just saying....LOL.

listen to thread 24 and 25,,,those guys are real shooters (not keyboard shooters) ,,,,you should polish the end of the seater stem,,,and seat them till they touch bottom by feel,,,,Roger

Dang man, those don't look so good. I seat with a rcbs bench primer, cuz i have carpel tunnel. I switched to Remington 7.5 and for whatever reason they require more force to seat than any other primers I have used. I loaded 500 pieces and later discovered some were above flush. Since then I mash that handle with 2 hands with all primers. Even my barbaric method never leaves a mark!

Just do what alex says. When he gives free advice, you would be a fool not to follow it unless your own testing proves otherwise.

You could always use a press to more easily crush the primers below flush if that's how you like seating them.

Some guys also worry about how shiny their brass is
----------------------------------------------------------
I stopped cleaning primer pockets years ago, when I stopped worrying about how long to tumble my brass to make it so shiny and pretty again
Whose gonna see it? And personally, is anybody more your friend because of it?
----------------------------------------------------------
Within Uniforming pockets...all I do is take one light cut just barely enough to ensure the bottom of the pocket is even all around the circumference where the primer bottoms out against
just in case there is any divots
I dont make it deeper unless primers sit above flush
-------------------------------------------------------------
My thoughts on this:
1. The primer is going to back out upon ignition
2. the case is going to stretch to full chamber length and reseat the primer again
3. Why have the primer going back and forth .005 - .008 in the primer pocket?
4. Once seated from the case backing up, it will not seat back to the depth you originlly seated it to below flush which leaves a margin of gas to possibly escape by
If anything.............now call me crazy
I might want my primer actually sitting .001" above flush
so that the whole time everything is happening the primer is actually being seated by force providing a full crush seal during ignition and powder burn
