Was out working up a load for my 500 gnr using hs-6. Velocity was where I wanted but the cases came out very sooty and just covered in black. The cases came out very easy and no indication of high pressure that I could see. Just wondering if that's normal for hs-6 at higher levels( took it to 17.0 @ 1153 avg 3 shots with a 375 gr cast.) Or do I need to use a different powder.

Also shot some imr 4227 which came out clean. Is this normal with hs-6?

- Pressure very low and cases don't expand to seal... - Huey, 2019-12-25, 17:06
  - And...That's a very sturdy case which worsens... - Huey, 2019-12-25, 17:10
    - Should I abandon hs-6 and stick with 4227 - Josh t, 2019-12-25, 17:24
      - I've never loaded for that cartridge... - Huey, 2019-12-25, 17:28

        Just looking for a load about 1000-1100 - Josh t, 2019-12-25, 19:34
        I see HS-6 is between Unique and Blue Dot / 2400 etc. - WB, 2019-12-26, 09:50
        I lean on 231/HP38, Titegroup and Unique in big cases... - Huey, 2019-12-26, 09:57
