I had seen where someone had posted about making a non-ejector barrel to an ejector barrel. I did do using my shop tools, radial drill press and a 16" drill press. I am just a hobbyist gun smith who likes to work on my own L.C. Smiths. This one is for a 16 ga. Field Grade that had a Hunter One Trigger and ejectors but the barrels were cut on the original gun.
hope you enjoy them, I had fun doing it and would do it again.
The hardest thing I have done so far is to take a stock that was not for a Hunter One Trigger and make it for a HOT. You think there is not much wood on a side lock shotgun, well there is even less once you remove the wood between the locks to accommodate the HOT. I used my mortising chisel and used the original stock as a template to guide the mortising chisel down through the inlet for the top tang to the bottom of the trigger plate. Tried it many times and finally put the good stock in and then took me about 20 minutes to get the nerve to pull the handle to the mortising chisel. Worked out great but I wouldn't try it again.
