Curious about the possibilities of this powder with bullet weights between 150 and 200 grains.
There is a fair amount of data in the pull-downs section of factory ammo that uses this poweder. Looks like about 10 reference loads in the 150-200 bullet weights. Check out the master section and filter the google sheet for silhouette and 150-200 grain.
The spreadsheet has links to the threads on the pulldown, which often include members comments about the ammo or about similar loads they have worked with.
