Most company's say to keep the plated bullet at 1250fps or slower, as the case with my Xtreme 115 and 124gr plated bullets.
Bullseye, w231 and HS-6 gave me high fps with a short 1.10" OAL
W231, CFE pistol, BE86 and green Dot at 1.12" gave me target to standard 9mm loads.
Unique gave the 115gr "Ball" 1263fps in my C9 3.5" and the 115gr Gold Dot reached 1208fps.
4" standard load is around 1180fps.............

The Xtreme 124gr RN plated was loaded with a 1.12" to 1.165" OAL, with the 1.14" length putting out the highest fps and the best accuracy with eleven powders that I loaded.
W231 worked at 944fps and Unique reached 1140fps for target use.
The Speer 124 Gold Dot JHP pushed by Blue Dot reached 1229fps in my 3.5" barrel.
4" standard load is around 1150fps.................

Have fun.
