Wamadet Berdan decapper.

Post by PeterN2 » Wed Jul 21, 2021 5:16 pm

A notice appeared at the club a little while ago of a list of items that had been donated by a member for sale to club members, the proceeds to go to the club. No prices are listed, just open to offers. Among the items is a Wamadet Berdan decapper.
This has been used as the top of the larger punch is hammered a bit. The smaller tube still has the original dried on preservative on it and it still has the pimple on the top from when it was machined. I printed off the instructions from the late David Cushman web page.
I don't really need this as I have boxer primed cases for all the calibres that I reload for but I thought it would be nice to have so I got it. I haven't been able to see the chap dealing with the money, so I have not paid for this yet. What should I offer, £20? I don't think anyone else is interested in it.
I had a go with it with mixed results. I tried some South African .303 head stamped A81 7.7 R1M3Z.
I managed to decap 11 of these, some just would not decap.
I tried some .303 head stamped 303MK8Z nny-81. This used to come loose in 250 round cardboard boxes and were covered in a greasy substance that you had to wipe off before shooting.
I had the same result as the SA stuff. I decapped 10 but some would not decap.
I tried some .303 HXP 73. These are boxer primed but I tried them anyway. These all decapped but sometimes needed more than one thump.
I tried some 7.92x57. These are head stamped nny 1980. These along with the nny .303 have a red primer sealant. I could not get any of these to decap.
I tried some 7.62 RG85. These all decapped but some needed more than one thump.
I tried some 7.62 MEN cases. I only got one to decap. I have used the Prime reloader hydropunch on these and some would not decap but most would.
Lastly, I tried some 7.5x55 Swiss G11. These all decapped easily on the first blow. What a relief. I was beginning to think I was doing something wrong or my thumping method was at fault.
I used a 1 1/2 pound claw hammer at first. The ones that did not decap often resulted in the punch bouncing up and falling into the tank or outside the tank. The Swiss G11 decapped using the Lee hard plastic hammer.
If anyone has any experience of using this decapper, I would be interested in any advice on how to decap hard in primers. I presume once they are decapped and reloaded, the primers will pop out like the Swiss G11.

It was fun and there is a future in the G11 reloading. There are also 2000 berdan primers to go with this, a mix of RWS an No.81. I have not got those yet or offered a price.

Peter.

I had another go at decapping the cases that I could not decap at my first attempt. I got a 2 1/2 pound lump hammer and tried again. They all decapped. I think I have this thing sorted now. Now to reload some of the cases and take to the range.
Regards

I've never tried reloading Berdan surplus ammo. Apparently you can use a standard boxer primer though in reloading. Is that right? Are there any Berdan specific primers made?

You need Berdan primers to reload Berdan cases. I have picked up some over the years and have my name on another 2000. They are still made by RWS and I think others in Europe though supply is intermittent. You can't use Boxer primers without modifying the case to remove the anvil in the primer pocket.

I had seen something that suggested boxer primers could be used in berdan cases once the old primer was removed. Can't find what I was reading now. I found that to be suspect when I read it. :oops:
