Greetings Mike Roberts and All,
Your comment about the choke in the Green River Works barrels is very interesting. It is something I had completely forgotten about, maybe because my two barrels do not have any apparent choke.
When the GRW's operation shut down, some individual purchased the barrel making equipment and continued making barrels. My barrels are not marked Green River, but they were purchased from a gentleman who I trust. He is the person who confirmed the story I had heard about the second party production of GRW's barrels.
I am quite sure my barrels are from the second generation of GRW's barrels, and therefore may not have been choked. It is also possible a special run customer order without choke was produced.
Anyway, my two GRW' barrel do not have any choke.
My old Mentor, "Judge" Resley, always choked his barrels. Best accuracy was obtainable only if a felt wad over the powder was used. The patches were not cut if the felt over wad was not used, accuracy was just not as good.
Best regards and good shooting,
John L. Hinnant
