The .50 shot 80 gr of Goex FFg and a 300 gr XTP.
The .45s known most accurate load is 70 gr of Pyrodex P and a 200 gr XTP (10mm) using a Harvester light blue CR sabot.
BTW I did order the Lyman 57SML sight. I should have it by the end of the week.
Going to put the T/C sight back on the .45 Hawken and put the Lyman sight on the Rene. I don't like how high I had to extend the screw (elevation) on the T/C sight on the Rene.
