220gr ELD-X in 300 Win with RL-26
I just got back from the range. I used Hornady's recommended load data for 220 ELD-X with RL-26. The 74.0 grains was max load for me at 2860fps versus what Hornady shows as 74.4gr at 2850fps. Best accuracy seemed to be at 73.0gr at 2830fps. I am 0.083" off lands to get a round that will cycle in my Ruger M77. I also loaded 3 rounds at 0.026" off lands (single feed only), 73.0gr and 2865fps. This delivered a 0.75 MOA group. I used CCI 250 magnum primers and Winchester brass. I was surprised to see the increase in velocity between 0.083" and 0.026" at 73.0gr without seeing the flatten primers of the 74.0gr load yet exceeding the velocities.
I am going to spend some more time with loads around 73.0gr with various seating depths.
My preferred load has been 180gr Hornady BTSP at 3080fps with RL-19. The bullet drop of the 180 BTSP and 220 ELD are nearly identical out to 1000yds, however the ELD has 25% more energy at 500yds and 50% more energy at 1000yds! Estimated drift of 10mph cross wind is 1/3 less with the 220.
