Has anyone out there noticed a difference in velocities between the new H-1000 Extreme and the older version? I've been shooting a 220 MK with 91.5gr of H-1000 out of my 300 RUM Sendero sf.I recently loaded a box with the newer H-1000 and got an aprox. a 100fps more with the newer powder accompanied a sticky bolt,cratered primers....and yes lousy groups. To verify it was the powder I got 20 new cases and loaded 10 with both the H-1000 extreme..and 10 with the older version. The older version gave the same velocity I used to have....avg.2950fps....the newer extreme version 3140fps...and more of the same pressure signs. The Extreme version,by the way, has a very green tinge to the color. Has anyone else noticed this in their loads or did I get a bad batch?
