Hi all, anyone know where I can get the primmer removal tool for berdan primers?
I have some 7.5x55 swiss surplus ammo and would be ashamed to toss it. I can get my hands on Berdan large rifle primer .217 so I'm good to go.

it can be, but that surplus brass is actually good brass and its ashamed to just throw it away

Our past club president tried reloading that GP11 and after his 6th attempt he managed to only equal the accuracy of GP11. (Im sure YMMV)
Im sure at some point I will attempt it too :)
 
I think canada ammo has some berdan primers, large rifles for 30$/1000

Decapping berdan is a pita. Canada ammo's NC 7.62x39 comes from berdan cases with corrosive primers, so they have to deprime them. The machine that does it is industrial and uses water. Depriming a meaningfull, yet non-massive amount seems like a real pita, whether you use rcbs tool or hydraulic pressure. I think water + 30cal rod (and hammer) + shellholder will be faster than the rcbs tool.
 
RCBS has a decapping tool made to handle Berdan primers and a die for Military crimped primers. I don't have one, but when I went to buy my garden-variety standard RCBS decapping die, the LGS asked me whether I wanted the heavy duty tool for Berdan primers, an HD version of the decapping die for Military crimped primers or just for regular primers. The military HD decapping die version for crimped primers was, as I recall, about $10 more than the standard, RCBS part number 87536 is listed on their site for military crimped primers. A Berdan decapping tool (not a die) is p/n 9525

I didn't find the rcbs tool that difficult, you just have to smack it with some authority. I found it much better than the water method.

Not difficult but compared to a press with a decapping die (for boxer), I'd think the tool is much slower. Otherwise we'd use it for boxer primers too.
 
I have a hydraulic deprimer similar to the one in this video, if anyone in the Ottawa area wants to try it out, shoot me a message. I had it made and shipped to me from Russia.

 
I use the RCBS decapping tool quite a bit. The trick is to get the pin adjusted for the case you are using. What speeded up the process for me was that instead of using the rod that comes with the decapping tool I screwed the seater die upside down in my press and use that to hold the case. Drop a case in, pop the primer and off to the next one. Helluva bit easier on the old hands.

Make a setup of 9 or 12 of the tubes, with as many pistons, and I see a system that would be much faster. Insert 9 cartridges, plunge it in water, place the 9 pistons, then WHACK WHACK WHACK WHACK WHACK WHACK WHACK WHACK WHACK and you got 9 done. One at a time it's long to wait for the tube to fill.
 
Those are speced at 0.99" cup height, the shorter length of the two 0.217" diameter Berdan primers.
Might be a problem in the 7.5x55 case since it uses the Nato spec 0.11 Cup height.

There again, I have only used the RWS primer size 5620 with a cup height of 0.10" with thankfully no problems
