I'm still trying to figure out your suggestion about holding the muzzle down and shaking a Colt Series 80 pistol to free the firing pin???????? smile

I find it pretty amusing that you passed on using a steel rod because you were afraid that it might ding the crown...but you have no problem using something that might damage the chamber.

Why not post some pictures of this "mystical" reamer gag you use...and explain exactly how you set up this reamer to be concentric.
