I think so, eastwood. I would not handle Berdans unless it was the ONLY way to shoot the gun.
What caliber has got you thinking about it?
Hydraulic decapping like the guys describe is a mess. I read of one failed try; the primers were crimped or corroded in and enough pressure to decap bulged the brass badly. I have seen plans for a balanced pressure hydraulic decapper that would prevent that, but even messier.
Wamadet made the Hydro Punch that put a nozzle down inside the case over the flashholes and you whacked the piston with a hammer to apply hydraulic pressure only to the primer. Claimed to decap with two drops of water per case. No mess but you still had to dry the brass.
Prime made a floating decapping pin to use in a sizing die in the loading press, almost like Boxer. The pin was offset and very thin, the stem floated with some play. You raised the ram slowly and felt the pin into one of the flashholes and then raised the ram to decap. Better have a lot of spares of the little pins.
Then there was the Power Punch. It positioned a common Boxer primer, anvil down over the Berdan flashholes inside the case. Then fired it, blowing out the Berdan primer with its flash. Expend a primer to decap a primer. Kind of expensive, noisy, too; but simple and dry.
