Not that I know of. There are not many of us Arndts around. I bet he's a great man tho.

Just checking. His first name is Richard.

My Endeavor likes these loads:
110gr of BH209, a 250gr SW with a Harvester short black sabot, or the same powder load with either a 200 gr shockwave and the supplied blue sabot, or a Hornady FTX 265 gr/.430 with a Harvester green sabot.

All of these loads produce around one inch groups at 100 yards. Hope this helps. Any of these loads should work for what ever you are going to hunt.
