Finally got some range time with the KRB I picked up about 6 weeks ago. All I can say is Awesome Baby!! Took a little time to get the Leupold dialed in but once I did it was consistant ranged 100 yard, sub 1 inch 3 shot groups. 85 grains 777 with T7 primers and 460gr NEX.504 Bullshop conicals and .510 dia shot cards. This rifle is definitely a shooter with conicals. Next time out I will see how she does with Shockwaves. Thank you IndianaSmokepole for all your advice. You the man!!
