Painted Mohawk SASS 77785 Posted March 28, 2020 Share Posted March 28, 2020 Does anyone know of or have experience with this Efemes Enterprises [ New York ] power punch decapper. It looks like you use a new primer to dislodge the old one...hoping someone can tell me exactly how it works ...thanks. Link to comment Share on other sites More sharing options...
Sedalia Dave Posted March 28, 2020 Share Posted March 28, 2020 The link is to the original post. Copied the important stuff. Berdan primer removal tools Quote I have a Jaguar/Rolls Royce customer that got a bunch of firearm related parts, tools and ammo from an Estate sale. He traded me some Berdan primer removal tools. RSBS claw type remover set and some OLD Efemes Power-Punch Berdan deprimers. One is 8mm (mauser size .325") and the other is .425" (44 cal?) I kinda figured out how to use the Mauser tool and I decapped some 1950s Egyptian 8mm brass cases I have. You load a .210 primer in the end of the tool and insert it into the case to the bottom of the case. Push down hard on the base part of the tool, put the 'firing-pin' into the tool and tap it with a hammer. The .210 primer explodes and pushes out the Berdan primer into the base that has a hole in it to catch the primer. Does anyone have any .30 cal sizes or have owners manual for these tools. I hope I am using it correctly. It works and I have all my body parts so I must not be far off on it's operation. I can make a .312 case insert from a 5/16" rod and drill the end to .210 for the primer pocket and have a .30 cal adapter but it would be quicker to buy one. Kind of a cool tool but it takes a primer to lose a primer. Not much info on the interweb about this antique tool. bob Quote Here is a pic of one of the tools (8mm). The other one (.425" tube insert) is in the deteriorated box behind it. The brass case is a Berdan primed Mauser sitting in the lower cup. You place a .210 primer in the end of the tool and fit the case over it. Insert the 'firing-pin' and tap it to discharge the primer. That will 'blow' the Berdan primer from the case. The TulAmmo primers are the correct 5.5mm size for the Egyptian brass cases. I have several other sizes from Old Western Scrounger. I also have the RCBS tool on the left. It takes some finesse to manipulate the tool. bob Link to comment Share on other sites More sharing options...

Duffield, SASS #23454 Posted March 28, 2020 Share Posted March 28, 2020 That RCBS claw type Berdan primer remover is a lot faster and more economical. Duffield Link to comment Share on other sites More sharing options...
