Friends,
Thank you for your encouragement. You don't know how much it matters to me. However, I am trying to be reserved in my optimism because I know I don't know.
Every new step I go through is a new territory that I have to explore cautiously. If I make it alright, there is great reward to be cherished. Sending it out would be the easiest thing to do and most cost efficient. But I would be missing the excitement of the discovery. I obviously am an adrenaline junkie.
Nial brings an important point. My barrels were bent up and I straighten them to the best I could. I know they are not perfectly straight, just by looking at the light reflection. Here is the problem. One wants to ream the chokes from the chamber with a guided reamer so that the chokes do not come out of alignment. If the barrels are not perfectly straight, the reamer may be misguided and the choke cut out of POI.
I might do better with a nonguided wooden dowel and emery cloth to allow a selfcentering tool to do the job?
The other option is to go very slowly and pattern after each cut to catch on an early changed POI which I am going to anyway.
The third option is to use a concentric guide close to the muzzle and see if the shaft would need an eccentric guide at the chamber, assuming that the last third of the barrel preserved its straight path.
Maybe I am complicating things too much. After all it's a shotgun, not a rifle.
Again, thank you for your support.
