| If anyone has any imformation about good loads for the 10 mm AR produced by Olympic Arms they would be greatly appreciated |

I get best results using slow burning powders like Blue Dot. The loads in Speer #13 work well with this powder. I think the single biggest secret to good accuracy with the 10mm auto is consistent brass length. Using a Bushnell red-dot sight I get "ragged hole" groups out to 50 yards with freshly trimmed brass. Since the cartridge headspaces on the case mouth, I think overly long (or varying length) brass gets "crimped" when slammed by the bolt creating uneven pressures and inaccuracy. That's my theory anyway. I do know for sure I get bad groups with untrimmed brass. Scot |
