Developing a load for my 6.5 x 284. Decided on Lapua Brass, H4831sc powder, Fed 210 primers and Berger 144 gr bullets loaded to start at .010 off lands. Did a ladder test and then an OCW test and found 2 nodes, one at 50.8 gr/2880 FPS and the other 52.2 gr./2970 FPS. The 52.2 gr posted a .282” at 100 yds. The 50.8 a .320 at 100 yds. So I decided to do a 5 shot group at 300 yds with the 2 load nodes to see how they grouped. Now I am kind of perplexed. The 50.8 shot 2” vertical x 1” horizontal. The 52.2 shot 1” vertical x 2” horizontal. I shot in gusty wind conditions because I figured both groups would string horizontally with the wind. Can anyone explain why the slower bullet might not string horizontally as much as the faster load. Or how do I read this to pick a node to stick with.
