The modification of the Carrier Block to run C45Spl in the front loading Henry is simple. Set the round in the carrier, and at the rear of the case mark and drill the carrier for a set screw. The set screw has to be cut to clear the flat part of the Breach Block and you have to cut a slot in the fat part of the breach block to clear the screw. Done.
This sounds easy enough but anyone have some pictures or care to elaborate more?
Here is what I was thinking. Drill and tap for a set screw. Loctite it in. Then I am envisioning a small round file to cut a slot in the breech block to clear the set screw in the carrier. Trying to save the $172. the Smith Shop wants for a modified '73 carrier that will wok as there doesn't seem to be any Henry carriers.
Appreciate any help/experience offered.
