[QUOTE="mferrell, post: 2000428, member: 115682"] I got out to the range this past weekend and was able to go through the 2nd round of load development testing. Shooting Conditions: 93 degrees and a head wind. Below are the results. 56gr R26 w/156 Berger: Velocity: 2904 fps, SD: 12, ES: 23 FPS [ATTACH type="full"]219613[/ATTACH] 56.5gr R26 w/156 Berger: Velocity: 2929 fps, SD: 8.7, ES: 24 FPS [ATTACH type="full"]219614[/ATTACH] 56gr R26 w/140 EH Berger: Velocity: 2946 fps, SD: 5.6, ES: 13 FPS (without first round group size .31") [ATTACH type="full"]219615[/ATTACH] 56.5gr R26 w/140 EH Berger: Velocity: 2966 fps, SD: 12.2, ES: 29 FPS [ATTACH type="full"]219616[/ATTACH] 57gr R26 w/140 EH Berger: Velocity: 2993 fps, SD: 13.1, ES: 27 FPS [ATTACH type="full"]219618[/ATTACH] During testing none of the loads showed any pressure signs. I am happy to see that the velocity and accuracy of the 156 gr Bergers are coming around. With the 5 powder charges I have tested so far the group sizes, ES, and SD's have continuously improved. I will load one more batch with 57grs and see if it continues to follow the trend. Being in Texas I don't want to push it to the very edge due to the temperature extremes we see. The 140 Berger have seemed to go in the opposite direction. The group sizes have opened up as well as the SDs and extreme spreads. I plan on jumping up another 1/2 grain and see how that performs. All in all I am still pleased, every batch I have shot so far has been less than an MOA so there is no doubt that the rifle can shoot with various loads. [/QUOTE]
