I shot my Investarms .50 Hawken for the first time this year. I got my best group ever at 50 yards using 55 grs. of Olde Eynsford 3F and .018" ticking patch for the first time. I put a little extra Precision Lube 2000 on each patch. Hornady .490 balls. And I ran a cleaning patch between each shot. Forearm was on a rest.
