This is the first time I have tried a Primer Pocket Uniformer.
I am useing an RCBS Cutter and I think it is cutting to deep.
I seated a primer and it is recessed by .013
I Primed a new Winchester case that I Uniformed and it is recessed by .013
I primed a New Winchester case that I did not Uniform and it is .005 recessed.
.013 looks recessed to much.
What should they be ?

The only info I have says

small rifle and large pistol .....0.118" to 0.122

Large rifle ....0.128 to 0.132

I have a Lyman hand tool uniformer that is set to a certain depth so it only goes so far.

You might want to get other sources, I could only find one and it was on a site that sold primer pocket uniformers.

If I'm understanding correctly what you are asking, the recessed depth of the primer should be 0.003" to 0.005" below flush of the case head.

Hope that helps.

Yep that's what I'm asking.
Thanks
Looks like uniforming is not the way to go, because the new brass is already at .005 with a seated primer.

Unless your gun is up to shooting groups of 1/4" to 1/2" regularly don't waste your time on primer pockets.

I don’t think that it is a matter of what it should look like but rather where it should be, which is just touching the bottom of the pocket.

One of the first things that I do when inspecting ammo loaded by others is to casually run a finger tip across the head. By far, the majority of these have the primer flush with the case head. This is common for a lot of the presses out there. Is this wrong? I don’t think so!...it is something that IMO could be improved on but does work well.

I would have guessed my own as being anywhere from .005 to .008 below the case head but had not ever measured it. I do have to use a priming tool to achieve this. I would revisit the speck’s, We have one already which has been provided by jimster and that one say’s that you are within the specifications.

I would go ahead and use the Uniforming tool if I were you. It does great also for cleaning dirty pockets that have already been uniformed. Don’t overlook the flashole uniforming tool also…there is a lot of small stuff that can be done to get you within 1” moa which is great for a hunting rifle.
