berdan primers

You can't.

Pretty simple.

Just get berdan primers.

The two primer types are not interchangeable.

Some have tried boring out the berdan notch, with very limited success. The primer lip you are left with is insufficient to promote reliable insertion and functionality of boxer primers.

Boxer primed can be had.

Wolf gold comes to mind.

Good luck !

Berdan decapping tool

That tool is made of headaches and evil.

I have used the RCBS tool to decap several hundred berdan brass cases, both 7.62x51 and 7.62x39. It works good but does require some patience. I have reloaded these cases with no problem.

Yes ... yes it is. Well said.

I have done the hydraulic method quite successfully. Maybe a bit messy, but out in the garage it is no problem.

Dont bother.

You cant get Berdan primers anymore.
And Boxer primers wont work.

That tool in the huge pictures is friggin' expensive too. RCBS wants $77.95 each. Make some drawer pulls and throw the rest away. It's not worth the time and effort to muck around with Berdan primed anything.

RCBS tool works well with some headstamps, not at all with others. Yes, it takes more time to deprime.

I tried hydraulic, but did not use proper case support or build anything to equalize pressure. Others have done it successfully, mine just bulged the shoulders out. I saw the RCBS tool at Palmetto State Armory on sale for $39 and bought it.

I don't load them, but way back when, I tried using mineral oil to avoid getting water all over my press. I filled the case about half way up the neck, then I used a bullet and seated it until the primer popped out. I only did a couple just to see if it would work, that was the last time I goofed around with them.

I've tried converting cases, using Berdan primers, just not worth the effort. Find boxer primed cases and don't look back.

Powder Valley and Dag Ammo carry Berdan Primers.
