Need a stable mount for the case as you will be prying on it. I use a 5/16 bolt cut off and mounted to my bench.



Hook grabs rim, pin grabs primer. Have to have pin adjusted correctly or it will eat into the anvil of case.

You can see this in the OP's pic. He needs to back off pin slightly.



Probe tool to clean out flasholes and scrape crud out of primer pocket.

Yes Berdan primers are slightly larger than Boxers in the size used in 7.62x39.



Boxer primer would fall out of the Berdan pocket.

Notice the stop I installed on the RCBS hand primer (first model).

You are seating primers against the cases anvil, and I like mine to be .002 to .003 below flush, just like a factory round.

If your talking to me, it all started when I bought that decapper (RCBS Lachmayer tool) at the funshow.

I knew what it was so I asked how much? Got it for $2 as guy didn't know what it was. (new price $70-80)

Started playing with it and figured out how to adjust and use it. Broke the decapping pin, RCBS sent me 2 replacement pins.

Years later found another one at the funshow for $2 also, added it to my gear.

Berdan primers ( I had bought 1K to try) were in stock back then 2005, then obozo, came back into stock in 2014 and I bought a lifetime supply.
OOS now.

Every range trip I bring a magnet with a stick and harvest free steel cases.

Tumble them in walnut to get the grime off, a little rust on the case doesn't matter to an AK.

I cast a 160 gr bullet from free lead and powder coat them, I use 15 grs of 2400, which cycles an AK just fine.

So round cost about .08 each. Primer .03 and gas check .03 maybe .02 in powder. Free steel case. No steel cases won't hurt your dies.

I enjoy this hobby so the extra effort is fun for me.

I bought that Kit.







Tried it, but not cost effective for me as I have plenty of the correct Berdan primers for 7.62x39.

Berdan primers are not standardized, there are many sizes. You need to measure your primer pockets to get what will fit.

For instance you could seat the low pressure primers I use for 7.62x39 into 7.62x54R and have problems with the extra pressure.

The drilling part goes well as this is a high quality tool.

When I bought mine last spring, had problems with ordering and site took my order to only have order cancelled due to OOS a couple of days later.

Never got an answer to my emails.

Eventually persistence payed off and I got the tools.

This would be a good tool for the larger Mil sup rounds.


edit to add,   Nowhere on that site does it tell you the size of the sleeves other than S, L, XL.

Notice I wrote the measurement down on the sample bag.

Yes, the ones in 7.62x39 are all that I tried.

I only used them with Brass Berdan cases and LR Wolf primers.

I would say it's a good system, but it costs ya.  Don't lose any cases.

What I did was figure out what size I needed from the starter kit, then ordered 2 bags of the size I needed.

The above proved to be a 3 month process (explained in a post above), but I did finally get what I ordered.

I like it.
