In Hornady Brass with 55.6 gr RL-26 and a Federal 210 Primer, I hit the 12 inch gong @ 800m almost every time with these bullets. At 500m i can regularly hit the 6 inch gong with them. There are other measures for a bullet, but these and a number of instantly dropped game animals are all that I need. I also shoot the same in 7mm and 338 with the same accuracy. Don't think I'll be switching anytime soon. Make sure to get the custom seating stem for the best results, although standard stems will likely still be very good.
