Got to the range today for some more speed checks with 150 grain bullets. I used Sierra SBT and 150 Power Hammers. Increases in velocity were not always consistent with powder load. Max load with the Sierras was 34.5 RE7 @ 2681.

@mopardoctor ,
Thanks for the data. I believe you (or someone else) posted something for this carbine - but I have no idea what bullet it was or where it is in the tables. Please include your rifle/barrel/ twist info for this new data so I can enter it (or tell me what the other bullet was)
Thanks
