Berdan Primer decapping tool

Your local gun shop should have at least one in stock. Have you tried them????

Several of the banner advertisers on this site carry them as well.

I have the RCBS model but don't really like it.

I've found the quickest and easiest way to deprime Berdan primed brass is to make up a punch, using a drill stem of appropriate size and a block to hold the base of the cartridge so I can just give the punch a tap with a small hammer to knock the spent primer out.

One issue with Berdan primers is that they are a few thousandths larger than Boxer primers. At least in most cases. The last batch of Dominion primers were on the small side.

As far as someone not being able to mathch or only match GPll?????????? That depends on the shooter's/rifle's capabilities. My Swiss rifles, like all rifles, each has their own personalities as far as loads they like. One won't shoot GP11 well at all and the other shoots it better than I can hold. Same goes for every other rifle I have other than a couple which just shoot everything well.
 
I have decaped GP 11 with both the RCBS berdan decapper and the hydraulic method . Once i got the hang of the rcbs tool i found i could remove berdan primers fairly quick and easy. I have been using Tulammo berdan primers bought from Doug Rayner "Raynershine gunworks", Lancer, Sask. I use an old lee ram prime to seat the primer and find i have to take care not to seat them too deep.

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.

No real time savings. You still spend the same amount of time filling (which is pretty quick with practice - just dunk the whole thing in the bucket). Also you can't really let them sit with water in - water leaks out albeit slowly. The dude in the video I posted is slow and inefficient ;)

I timed my depriming and it takes only a few seconds longer than depriming on the press, the only complaint is having to wait for the cases to dry afterwards. If I'm really pushing myself I can easily do 10 cases a minute at a very relaxed pace. I keep the plunger in my right, pick up the case with my right, put in the deprimer, dunk to fill, put in the plunger, grab the hammer and strike, dump the water and case while catching the plunger in my right palm.
 
The biggest issue with salvaging GP11 brass for me isn't getting the primer out, (although I'd love to find one of those RCBS tools for sale in Canada) but it's the lack of Bredan Primers available. I went on a search a while back to source some of the proper height Bredan primers for GP11 from dealers and no dice. They didn't even want to entertain the idea of bringing them in in the future. The ones CanAm has or had are the small ones for 7.62X39 and may not give full ignition in 7.5X55. I read some threads that folks tried them with little success in 7.62X54r and 7.5X55.

I did manage to find 1000 of the correct primers privately from a CGN'er but once they're gone, I'm not hopeful I'll be able to find more.

The solution may be to use one of these. I bought one but haven't tried it yet.

I too had issues with being able to use the tool when my arthritis went hyper-active, along with most other tools also. Since getting prescriptions for injected Methotrexate and Embrel autoinjector, I can use my hands at home and at work without undue pain.
 
I’ve tried the hydraulic method and the RCBS tool. I’ve followed a couple of the recipes to convert it over to boxer as well with not bad success. All of it far too time consuming, and I sometimes like to tinker.
I’ve finally found the easiest way to get it done and that is to just buy more GP11. I went a little overboard when Wholesale was selling it at 60% off and am now sitting on ~12000 rounds.
If I manage to chew threw all of that I’ll have the 600 rounds of Privi that will serve as loadable brass.
