can't decap 308 SBS brass

[AC MkIII]

Everyone I have tried has been to much for my Lee decapping die.
Is it worth the time to mess with them?
Thanks

Is it popping the pin up in the collet?

Or is it not fully popping the primer out?

i use lee decapping die with no issues..

make sure its not berdan prime though

 

[Sticky]

Yes, check to be sure it's not a berdan primed case... if so, scrap em.. lol

Popping the pin on the collet and they are boxer primed.
No problem with Lake City or any other brass. the primer crimp seems to be very tough.

I had that issue with LC 5.56 brass initially.

Just wound up increasing the torque on the collet, right around 35 to 40 ft/lbs., IIRC. I know I put something extra on it to make sure it stayed put. The die body and decapping pin are steel - so they can handle the extra torque.

OK that worked. Thanks! I didn't want to risk breaking the pin.

No problem.

Don't worry about the Lee pin, it'll bend - but I haven't managed to break one. And there isn't many things I can't break...

Had to tighten it a little more. Damn they are tough

S&B brass still gives me issues at times.

At times they'll pop out just fine, then there'll be a few that hang up just before they should pop out - extra sealant?, tougher crimp? - not sure why they do it, but they do.

I got this to handle 5.56 cases with military crimps. It is a beast.

After breaking 3 pins in my RCBS die I started throwing out the SBS brass. I have plenty of LC and Win brass so it's not a big loss.

The Lee decapping die is working fine now. The SBS brass is tough

I broke one.

But it took maybe 6K (or more) pieces of brass to do it.

I never decaped SBS brass but if I had really hard crimps I think I would try preheating the brass just 200 or 300 degrees, make sure no live primers first, and then try it. The case and primer may expand at different rates and/or the sealant may soften. Worth a try either bulk in the oven or setting them on a hot plate before decapping.

 

[AC MkIII]

All done now. Only about 20 SBS in the bunch. I could tell when I had one. All is good. Wouldn't really want to break out a torch near my reloading bench.

 

[Blacksmith101]

Never suggested a torch.

 

[AC MkIII]

And so you didn't but I thought it.

I occasionally get an S&B pistol case which has a very tight primer pocket and is crimped. My Dillon decapper handles the decapping OK although I can occasionally feel the increased/"ratchety" resistance. The next primer resists seating and I pull the case and ream the pocket on the spot.
Even after reaming out the crimp with a Lyman reamer in an electric screw driver the primers can still be difficult to seat and the primers are deformed(flattened) but still fire (although they are relegated to plinking status).
However, most S&B cases work fine. I wonder if these tight pockets are the result of a worn cutter.
