Hi Guys,
My Jeffery boxlock was made in 1912 and though in excellent shape, has seen at least a fair amount of use -- i.e. right bore worn more than the left with a velocity difference between the two. Both firing pin heads are shaped like a half moon and leave a half moon shape in the primers of fired cases. This has never affected ingition, but should I have them rounded off? If so, by whom? I have occasionally, when working up loads, experienced a little stickiness on trying to open the action, with loads that do not seem to be excessive (it is a .333 Nitro rimmed and there is very little, in fact no reloading data that I can find). Can difficulty in opening be caused by the pins sticking, or is it always the case that the metal has expanded from the pressure? Is this a common occurence with older doubles? Any info would be greatly appreciated. Thanks, Keith
