Clean Primer Pocket holes

Is it necessary to clean the primer pocket holes of brass after the primer is removed and before the new primer is seated?
If you do need to clean the pockets, then after how many firings do you clean the primer pockets?

What caliber are you reloading and what competition are you shooting?

Not necessary in pistol calibers, but I do it anyway. I'm kind of compulsive with my reloads. :roll:

Ditto to what Shane said, although I do it about every third reload.

Just trying to make sure that the primer seats completely and consistently.

I clean primer pockets every time before loading rifle casings and ditto with every third on handgun.

Because I load on a progressive press I bought a RCBS universal decap die and decap them all first and use a cordless drill with a primer pocket cleaner (brush type) and then tumble and it goes quick. Just part of my routine and it seems the primers seat more consistantly.

Never on pistol, only on precision rifle rounds.

Clean Primer Pocket holes

I am asking this for reloading 45 acp, 40 s&w, and 357 mag. I don't use these in competition, but just for practice. I appreciate yall's advice.

If this is just range ammo and not bullseye, I don't see the need. It won't hurt anything to do it but I have loaded many thousands and never cleaned a primer pocket.

Most pistols have a fairly powerful strike on the primer. If used in a revolver I would ask first if it has been tuned and the mainspring lightened a lot. If so I would clean the primer pockets at least every 3 loadings. If not lightened excessively I clean them when the pockets get excessively crudded up and it strikes me.

I do it; I've never heard of any advantage

Seems to me Precision Shooting did a survey and some of the folks ran tests long ago - easy to not clean when loading at the range and testing cases for in and out of the group - I've never heard of a test that demonstrated any advantage.

Personally I mostly decap with a punch and base, visually inspect and push down on a Lee Yankee Screwdriver style cleaner set handle down in the bench top - doesn't get the cases all that clean but some - then tumble which does. One of these days I'll go to agitating and still call it tumbling.
