Primer pocket uniforming Q

[tubby1]

Does uniforming the primer pocket between each firing reduce the life of the brass? Ive been doing it that way. Just kind of wondering if thats necessary, or over kill. Common sense tells me the obvious answer would be yes because the more times you remove material/work the primer pocket would lessen the integrity of the case in that area.

I only uniform the primer pockets the first time and then after that just clean them out. Seems like a ton of extra work doing it every firing.. not sure about pocket life by doing it that way.

The uniformers I use have a collar that prevents the cutter from going any deeper. I cut the pockets till the casehead hits that collar. After that, the tool isn't going to remove anything except what little bit that was setback from firing and that's resulting in loose pockets. IMHO, the only way you'll damage the pocket with a pocket uniformer is if you wallow out the pocket when inserting / removing or not using it square to the case, especially if you use one chucked in a drill. A pocket uniformer works good for cleaning between firings.

I just run mine once and then clean it out after each firing from there. i have read somewhere though that there isnt any loss of accuracy if the pocket isnt cleaned out. i dont know how true that is but i still clean it out. i need all the help i can get.

I dont uniform and only rarely clean my primer pockets.

I SS media clean and haven't uniformed pockets in 7 years = waste of time.

Agree, especially with quality brass.

So I gather that maybe my tendency to be OCD about the primer pocket is a little overkill, but at the same time I shouldn't be hurting anything.

Uniform once mainly on loading for semiauto.

I hit them hard the first time with fresh brass. Then use the uniformer again as an easy way to clean out the pockets. Only takes a second and doesn't really remove any brass.

I dont bother anymore. I can't see any improvement on the chronograph or on target.


I found that if I uniformed virgin brass, the pocket would set back some on the first firing. When I went to prep them for the second firing, I had to remove material again. I stopped doing it to virgin brass, just to save time/effort. Then I stopped all together.

Op, how much material is being removed every firing? Like trace amounts of brass, or serious cutting? Pushing hard with the load? Brass make?

Most of the time just small amounts. Sometimes ill get a piece of brass that looks like some serious cutting took place, but mostly its just the junk left in there from firing. My load is only a grain over the suggested max. Shooting Hornady 6.5 creed brass.
