Removing crimp on LC brass.

[thefiremeister]

I've got some 308 LC mil crimped brass and was having a little trouble priming the brass.

Standard brass prep nothing out of the norm unless the following is out of the norm.

I'm using an Rcbs prep center to clean the neck and to debur and chamfer the neck and to clean primer pocket. I'm also using the debur champher tool to remove the crimp.

I still go back and use the hand primer pocket uniformer and run it through the primer pockets.

Trouble is I still wind up with brass that the primers don't want to go into. It looks and feels like the crimp is gone and the uniformer goes in pretty easily but not some of the primers.

I'm using the RCBS APS hand primer

Is there a better way? Don't say get different brass that would be to easy.

Re: Removing crimp on LC brass.

I have been using the Hornady primer crimp remover tool for years,and have never had a problem with it. I have both small and large tools. I also use a RCBS hand primer ( not the APS), and have no problem priming brass. Perhaps the RCBS tool isn't putting enough champfer in the pockets is all I can think off. I'm sure someone who has this tool can answer better than I can. I do all my case prep the old way by hand.

be prepared to cringe:

a case chamfer tool to ream out the crimp.

A friend has the RCBS and warned me against it.
I got the Dillon Super Swage 600 military crimp remover,and I have been happy with it.

If you have alot of brass to remove the crimp on the Dillon is the way to go.

Re: Removing crimp on LC brass.

I have an RCBS primer pocket swager with which I've removed the crimp on several thousand cases. I have a Dillon now that is superior and faster...but much more expensive. Balance out how many you are going to do.

Only about a 1000 + rounds.

I'm trying not to hog out the whole primer pocket. I was just taking enough off to get rid of the crimp. I had figured that if the primer pocket uniformer went into the primer pocket then the primer pocket should be good. Apparently not.

Re: Removing crimp on LC brass.

The RCBS primer pocket swagger works well. It just takes some practice to get proficient with it. For $27 it can't be beat.
I bent 2 of the swagging rods when I first started using it, and RCBS sent me new ones. The tech also told me this was common and that most people initially set the swagger to low in the press and cause bent rods.

You do NOT have to fully extend the press arm to swag the pocket. You will get a feel for how the swagger goes into the pocket, and know when to stop. After "getting the hang of it", I have now done several hundred cases without an issue, and no further bent rods.

If I had 1k cases to swag at a time (like you do), I might consider the Dillon, but for the occasional crimped pocket, the RCBS does fine.

Worked for me recently. But, I only had a few cases to do. Interestingly, the Lyman primer pocket uniformer did what it was supposed to, but did not remove the crimp. The chamfer tool did.

Just like foxtrot I only had about 60 rounds to do though. The chamfer tool worked like a dream.

I had an RCBS primer pocket swager at one time and didn't have any luck with it so I gave up on it. It was like way slow and kept getting stuck and pieces kept falling off if I remember correctly.

I'll have to go look for it. I hardly ever throw anything away.

I'll have to look into a dillon. It looks pretty fast.

Does it keep the base of the case flat as it pushed the crimp out of the way?

Gonna have to get one for myself. Have about 1k+ of LC brass to de-crimp. thanks for the links gents.

I bought the RCBS Trim Mate along with their Lg/Sm decrimper reamers some years back and one of them, the Lg. one, doesn't bite enough and remove the crimp.

I use my Hornady bits in my TM and everythings just nifty.

Re: Removing crimp on LC brass.

I've tried reforming cutters on the RCBS Trim Mate, and it worked but was a little slow and inconsistent. The Dillon swager was quite a bit faster, and resulted in much more consistent primer seating. I'd recommend it in a heartbeat...

I agree saves a lot of time and effort.

Re: Removing crimp on LC brass.

I have done about 500 LC cases with <drum roll> an exacto knife and a sharp blade. You just hold the blade at the correct angle, and the crimp comes right off. You hold it at the wrong angles and the case is ruined.

Same thing I do it might take longer but no chance of lose pockets.

 

[thefiremeister]

Re: Removing crimp on LC brass.

The loose pocket thing is what I was trying to avoid.

I've bought some reloaded remanufactured brass before, 308 and 223, and the primer pocket has a pretty deep cut in it so I've opted to buy some once fired brass and decrimp my self.

More work and all but I feel better knowing I'm not missing a big chunk of the primer pocket.

I'm going to try the Hornady tool for the small lots I come across and maybe look at the dillon for the 1000+ jobs.

The chamfer tool just isn't consistent or I should say I'm just not consistent with the chamfer tool when I'm doing a bunch a a time.
