I'm Shooting a Knight USAK American Knight .50cal (#11 Perc cap) with a 1.5X4.5 Bushnell Sportview shotgun scope in see-thru mounts.

Best loads are 80gr of 2fg 777 loose powder with 300gr sabots - such as Hornady XTPs or SSTs or Precision Rifle Extreme or QT sabot rounds.

And shooting just as well are 90gr of 3fg 777 loose powder with 350gr sabots - like the Extremes or QTs. Also 90gr of 2fg 777 and 348gr aerotip Powerbelts are my 2nd shot backup for this load.

And when whatever I'm taking aim on has to absolutely, positively die on the spot - I'll load up 100gr of 3fg 777 loose powder and top with a 400gr Extreme or QT sabot...................kicks like a mule and will drop an elephant.
