	I've been having problems with a Winchester hiwall 32-40, the link that's also the firing pin retractor, acts as an interrupter. When I have a tight case, the block goes up, but doesn't drop down as it should, and then the firing pin retractor won't let the firing pin go all the way in to bust the primer. It's a royal pain in the ass! Has anyone else had that problem?

	I did years ago when I had a high wall re-barreled also in 32-40. The gunsmith got the headspace a little too tight and as you closed the breech block, it would actually wedge up at the top rather than dropping back down. I solved my problem by taking just a little off the face of the breach block to give more headspace clearance. It wasn't enough to worry about firing pin length that I only needed to take off .002-.003". I used a diamond file. You could also do it by removing a little off the back of all your brass. Bob

	The barrel tenon may be too long, the rim recess too shallow, or a combination of the two. .005 clearance from case head to BB face with the case seated will allow proper movement and drop. The reduced diameter at the end of the tenon may be too large, the step may be too short, or it may have too large a radius at the transtion.

	Just a thought. Not sure how the link could be blocking the firing pin, but relieving some metal on the ‘leg’ of the firing pin could cure that. Another option would be to turn down the shoulder of the firing pin and install a spring. A Bubba fix for a block that sticks in the up position is to carefully file the barrel tendon without removing the barrel. Jack “Parkenfarker” Hewitt
