My current load of choice is:

Projectile: .45cal Precision Rifle QT sabot
Proj. Weight: 350gr
Powder charge: 90gr 2fg Triple 7
Weapon: Knight USAK, .50cal, #11Mag caps

My back-up (2nd shot) round uses a 348gr PowerBelt Aero-tip with the same powder charge (this round loads faster for a second shot).

"Every moving thing that liveth, I give unto you as meat" (Gen 9:3)

Trust God..........but keep your powder dry!
