Shot the 600 yard match yesterday. Used IMR4350 and Hornady 178 gr ELD bullets. Each string of fire had a possible of 200-20. My first string was a 104-1. Second string was a 127-0. It was a slight improvement over the 150 gr bullets and IMR4895 I used last time. I used online load data from the Nosler site. In their testing, IMR4350 was the most accurate powder tested. 42.0 grains was their most accurate load so I went with it. It only has a velocity of 2190 fps. A tad bit slow for 600 yards perhaps? Their max load is 46.0 grs of IMR4350 at a velocity of 2460 fps. Maybe I need to try a higher velocity for the longer range. What say you? We were using standard MR-1 targets. Maybe I'm just expecting too much from the old gal. Every shot however, would have hit a man-sized target.
Thanks.
