Let me second the recommendation of the HPH 24 sabot in your Knight. Maybe try a bulk Nosler 260 gr. Partition, or a Speer Gold Dot,in that sabot. Another bullet that is hard to beat is the 250 gr. T/C Shockwave/SST. The SST has a tighter sabot than the T/C version, and may seat too hard in your Knight. Also,the Harvestermight bea good sabot to try in your gun with bulk bullets. Good luck.
