Shot these this afternoon from a 3 1/2" S&W 469. The 1st water filled gallon jug was at 10 feet. it was a light duty range day, so neither was chronographed today. The Norma was clocked at 1171fps @ 10' instrumental a few weeks ago. Norma spec is 1312fps. The Federal load may have been checked a long time ago, but I dont have the data. Federal says 1060fps @ the muzzle.
The propeller... the new Norma 108gr MHP completely penetrated the 2nd jug & was found laying on the bench. The 3rd jug was basically untouched. Dimension across the petals is .956" & .958". It weighs 106.6gr.
The more traditional shaped mushroom was an old Federal 135gr Hydra-Shok, from the tail end of the lot that I've been carrying in this pistol since about 2003. It completely penetrated 2 jugs & was found in the 3rd. Diameter was .598" on the small side & .632" on the large. It weighs 134.5gr.
