Sierra 75gr hp and the Speer hot core 75gr SPFN run just under 1100fps with 11.2 gr of AA-1680

The Hornady 60gr to run 1250fps with 12.5 gr of aa-1680

I thing they will go 1300fps with another half grain of powder and the case still not drag the fence from starting to back out.
Every gun is different as we all know. I thing the smaller everything is from the round itself and the little Hellcat, the more a slight change makes. All rounds where loaded with CCI mag small pistol primers. That Hornady may become the load for My Hellcat. I have a G2 barrel coming in 250GNR, I think W296 will be the powder for it. The Single six gun may handle a tad more!?! For myself I am super happy with the Hellcat. Note this new chronograph seams a bit slow compared to my last one, like 100fps, so it's worth what ever it's worth. FPS should always be taken with a small Siberian salt mine anyway

  - I think longer barrels and sealed breach add a bunch - WB, 2017-02-04, 14:57
    - the heavier bullets have a longer barrel dwell time - Gary Reeder, 2017-02-04, 15:22
      - My experience similar to WBs. I suspect the 250 GNR... - Huey, 2017-02-04, 18:02
        The .255 Banshee does that easily, about same powder charge. - WB, 2017-02-04, 20:06
