Small Primer Pocket Uniformer
I have one each of large and small pocket, but I think the hand held chamfer tool works better.
Mine is a vld style think that makes any difference.
I used that hand held tool... It don’t work that well. Mabey I’m not putting enough pressure on it
Chucked this tool up in the drill press at about 500 rpm and it took out a ton of brass form the new cases. Result was a perfect fit for all the primers. Bad QC at Winchester, but this tool will fix it as well as taking out crimps on GI brass.
Sinclair sells a manual holder if you don't have a drill press or a 3/8 inch hand drill.
Primer pocket uniformers just square up he bottom of the pocket and take it hair deeper if it is not deep enough.
A slight twist of a deburring tool will chamfer the entrance to the primer pocket, don't over do it.
What kind of priming are folks using that are having trouble with seating primers in S&B brass? I've never had trouble with it using hand primers.
Because really what type of y chromosome toating humanoid doesn't have a drill press.
Rcbs universal. Works great.
Use a proper tool. I prefer to swage the pockets since it does not remove material and moves it back to where it came from.
S&B brass might have changed lately. Two years ago I had no problems starting 45ACP primers but the pockets were shallow. Lately in 44 Mag and 9mm I can’t get primers started without chamfering but the depth is fine.
One thing is for sure with reloading, it’s always something! Still better than a day at work though.
I have one of these as well. It's a nice unit.
I do not make any efforts to uniform the primer pockets of brass that did not have crimped primers.
The chamfer does make the primers a bit easer to seat as there is a "funnel" to direct the primer into the pocket. I have not seen any adverse consequences from the chamfer.
The cases I’m using are dated ‘17, ‘18 and ‘19.
I bought the RCBS swager die but can't get it to work properly (center pin will not fit through the mouth of the cartridge).
It does. A VLD chamfer tool won't reach the pocket mouth. A conventional will, or use a countersink.
Mine works OK, but I prefer the one that takes shell holders. Probably just me, but cases pop out of it now and then.
