I was surprised today when first shooting these bullets. Had a previous load with 120 Nosler BT in my 7MM08 m700 mountain rifle so used the same load with the Barnes 120 ttsx. Barnes max is 47.8g Blc2 and I loaded 46 with the nosler previously so tried that plus stepped up to 46.5, 47, and 47.2g. 1 flyer with 46.5 but otherwise shot impressively for a 250yd deer rifle.
