Otto,
If there is no way to adjust the fireing pin,it may be a replacement, made too long.I don't have the rifle in hand, but it seems that the mainspring doesn't allow the firing pin to retract,until it is cocked(like you described).One way to handle this is to make a fireing pin(or modify the old one), so that it doesn't doesn't protrude past the face of the breechblock with the rifle uncocked.This would have to be an inertia type pin, with a spring to hold it rearward.I had a similar problem with a German fallingblock rifle,until I discovered that there was an adjustment that allowed the hammer to "fall back"enough after fireing that the fireing pin could retract to flush with the face of the breechblock. I can't tell if your rifle has any such adjustment.On the other hand, you could just rid yourself of the problem by selling it to me at a big discount, since it it is "busted".By the way,the rim recess may have been recut to allow cases made from 30-30 to work w/o thinning the rim.Some Martini type breechblocks won't rise enough to strike the primer in the center,if the rim is thicker than the rim recess.I hope this helps.
Mike
