Based on what I have experienced with all 3 of my Knights, a new Redemption and what I have read on Randy Wakeman and Toby Bridges' web stes and numerous postings on this and other blogs 105 to 110 grs. seems to be the "sweet spot" for BH 209 and a number of different bullets. After 3 years of trying various component combinations, I've locked in on 110 gr of BH 209, Harvester's 300 gr Scorpion PT Gold bullet and Black Crush Rib Sabot and Winchester's regular 209 primer. My best 100 yd 3 group to date, out of my Knight LRH (glass bedded and target trigger set at 2 1/4 lbs) was .297 inches. I harvested 8 animals this year and all were one shot kills and 6 of the 8 dropped on the spot. The other 2 made less than 15 yds. All were through and through, except for a 260 lb. Aoudad where the bullet was lodged under the skin on off side. Recovered bullet weighed 245 gr.
