Barrel threads are straight threads, not tapered pipe threads. If the frame and barrel have been properly threaded, there shouldn't be any reduction in bore diameter worth worrying about at the torque levels used in barreling revolvers.

Optimum forcing cone angles depend upon bullet material (jacketed or lead) and length of the bullet. Most of us can't tell the difference between any of the commonly used forcing cone angles.
