Well stubbed my toe today.
Have a Suscequential Colt. Had it out shooting a couple days ago and upon cleaning, noticed a lot of leading just ahead of the forcing cone. As I cleaned on the lead mine, I determined to re-re-discover what size boolit this revolver wants. I had been shooting .452 inch boolits both tumble lubed and lubed with SPG.
After cleaning almost all the lead out, I determined that the cylinder throates are .454. Grabbing a large boolit of .460 diameter, I greased it up and began pounding it thru the bore whereupon after it was 3/8ths into the 7.5 inch barrel, it froze hard and I could not move it.
Drilled it with 1/8 inch first. Followed by 3/16 inch. Then 5/16ths. Felt it go thru and hoped I did not feel what I was certain happened ... sure enough, after pounding it thru the barrel, I looked and there is the drill bit gouges in the barrel.
Fortunately I think I can shorten it to 4 3/4 inch and get below the drill fiasco. BUT it will be a shortened barrel and then be lessened in value. By how much I do not know ... any ideas as to the diminished value?
