Took my new 6" Python along with my old 6" to the range the other day.
I was shooting .358 dia. 158gr Missouri bullet lead SWC's on top of 4.0gr. of HP-38.
Results from Labradar.
New revolver yielded:
Stats - Average 856.3 fps
Stats - Highest 884.52 fps
Stats - Lowest 825.94 fps
Stats - Ext. Spread 58.58 fps
Stats - Std. Dev 17.88 fps
While the 1978 version yielded:
Stats - Average 751.03 fps
Stats - Highest 768.65 fps
Stats - Lowest 729.89 fps
Stats - Ext. Spread 38.76 fps
Stats - Std. Dev 14.39 fps.
Old Python is more accurate but after being shot for 45 years she has developed a 2lb. trigger pull.
Any clues as to why the velocities are so different?
