Fingers, the post up a couple states that he has a second gen Colt 1851 that has a .370 groove as well as a .370 cylinder bore.
I guess I have never heard this before. If this is an accurate statement, then accuracy wise, the second gen Colts should outshoot the imports all the time. I had not heard this fact before so my question is ... is this truly a groove/cylinder measurement or a misprint, or a special second gen gun?
