I met up with my friend Joel Y. to check out some custom loads he made in .357 magnum. Unfortunately the chronograph he borrowed was not consistent and had too many errors so we just ended up playing with a couple .357 magnum guns. A compensated Coonan, a 6″ barreled Coonan and his 3″ barreled S&W 60 Pro.
He and I didnt notice his eye pro was on his head. The fireball of the S&W 60 Pro is quite pronounced.
Here is the 6″ barrel Coonan vs a 2L soda bottle.
