RMR bullet users and Sport Pistol/N320 data collection

[Khaot1c]

I seem to recall that N320 is more temperature-sensitive than Sport Pistol.

 

Since most of my shooting is in the Florida Panhandle, our temperature swings typically aren't very drastic so I don't see much variance on the chrono.

 

With 5" KKM barrel in a Sig 320 X5, I'm only using 4.0 grains of Sport Pistol to hit 132 power factor wth a 124gran match winner loaded to 1.10"

 

Using a Walther PDP Match SF with a 5" barrel, I can use 3.5 grains of Sport Pistol with a 147 match winner to hit 139 power factor.   Sounds "high" for a gamer load, but the PDP Steel Frame groups and shoots VERY well with it.
