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.

Like Ken Mays, only do it for precision rifle, but even then will sometimes forget. So far, no appreciable difference in accuracy, reliability, etc.

rcbs rockcgucker and case kicker

I know several people that size and deprime theri brass in an rcbs rockchucker with a case kicker, then you can tumble to clean, and clean primer pockets if you like (esp. for revolver so they don't hangup the cyl) then they run them thru the Dillon, they slide thru much easier if already sized, ammo ends up cleaner because caselube is removed...and you never break a de-capping pin on the dillon

Whoa. That is adding several steps to a simple process. Although I too know people that want others to shoot up their ammo because they want to go home and reload the cases!! I always volunteer.

Cleaning primer pockets

The range I belong to has a 55gl drum where people can throw away unwanted brass. I always dig through the drum to see what treasures I can find. I can get all the 9mm Lugar & .40s.w. I want .45acp is harder to come by. To get to the point. Cleaning the primer pocket after decapping gives me a chance to inspect the brass. I found a couple of .45acp cases that had small splits in them. If I had just rum them through my turret press I might have missed them. I have a primer pocket attachment that I put in my cordless drill. I get alot of crud out. 8)
