This thread could almost be renamed to "Best Practices for building a Double Rifle, or converting a shotgun frame to a Double Rifle".

So far we covered things like sleeving barrels, calibers, regulation, frame selection, wood work, and now safety precautions. I like that.

My own Beretta also has these vents on the face. Its strikers are not very thin, but I reworked them, because they were protuding too much from the face (almost 1,5mm). This way, I have had no problems with the strikers perforating the primers or jamming the gun shut.

One question for all: all accidents I have seen with primers were either caused by faulty firing pins (too long or too thin) or by very high pressures in hot handloads. If we consider that the modern Large Rifle primers are built to withstand pressures much higher than those of normal DR calibers, is it really a necessity to bush the strikers?
