This is a highly subjective experiment due to so many variables, but I still had fun. Different revolvers, recoil based on feel and no tools to measure sound. There are a few things we can learn from the data collected.

Porting & Velocity
S&W model 65 nonported always turned in the highest velocity
S&W model 19 power port always turned in the second highest velocity.
S&W model 13 magna port always turned in the lowest velocity.

Porting definitely impacts velocity and increases muzzle blast but is very effective at reducing felt recoil.
