Question about Primer Pocket Uniforming

[hylander]

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 ?

i don't uniform my primer pockets for that reason. i would only uniform the primer pockets it was previously military crimped b4. i like my primer pockets as tight as possible.

If you are going to primer pocket uniform, you should adjust the tool to cut the minimum amount of material to square the pocket. Squaring the pocket is about the only reason you will want to uniform primer pockets. It's almost like neck turning.

I stopped uniforming pockets simply because it became a pain to set the uniforming depth all the time with different brass and I saw no real benefit.

My opinion, stop using the primer pocket uniforming tool.

The two tools that you will want are a flash hole deburring tool and a Dewey baby crocogator (primer pocket cleaner).

Dewey baby crocogator

I bet you can't say that 10 times, as fast as you can, without messing it up.

Agree... Saw no benefits with cleaning/uniforming the primer pocket.

i always clean the primer pockets and flash holes. some say no big deal. some say its a big deal. for me its all about staying consistant on what i do. Same time i use a hand pocket cleaner. not the rcbs. I have heard to many times the rcbs can cut the hole big time as whats happening with yours. You want to clean the pocket out of gun powder residue not cut up the hole. you can probably adjust it or just barely put it on one of those electric deals.

Here is why i clean the primer pockets and flash holes.

think of spark plugs in a car. can a car run on dirty plugs. Yes. Does a car run better on new or cleaned up spark plugs. YES.

When you pull the trigger your relying on the primer to ignite the poweder. You will have better ignition if there is nothing blocking the flash hole with a clean strong spark.

I will stick with cleaning Primer Pockets and Flash holes.
Already took the Uniformer back and more Brass

I use the Sinclair uniformer at each loading. It can only cut to a set depth (small rifle size cuts to 0.120" and large 0.131") and is carbide so it should last a very very long time. It also serves very well as a primer pocket cleaner (which is why I use it every time I load) Just chuck it into a drill and have at it.

Mine come out so that the seated primer is about 0.010"-0.012" below flush. If I had my way, I'd set it so they are 0.008" (but it's just a PITA to adjust). It hasn't been a problem. I cut them to buy more margin against slamfire in the M1A/M1. I also clean the pockets each time.

I've never had a problem with pockets getting loose (LC brass, RCBS pocket cutter).

I don't do anything with the primer pocket for bolt-gun brass.
