Range Report Ladder test question

[ghostwriter247]

So I ran a 308 ladder in half grain increments at 330 yds. Gun was strapped into a led slead to eliminate shooter error and I found two nodes.

41.5 and 42 gr were touching and so were 37.5 and 38. Everything else had significant spread

Would you load up .2 increments or just go halfway? I don't see how much closer they could get.

I can't see them touching being shooter error since it was in both nodes and had limited input being on a mechanical fixed rest.

Thanks

Did either of those nodes result in horizontal dispersion?? The closer of the nodes in the horizontal (as long as you can reproduce it), is what I would stick with. The difference in horizontal would more likely be the result of the shooter. Vertical dispersion is what I would do my best to try and avoid.

The lower node did show horizontal dispersion. But I'm betting shooter error. If u don't steady the sled it will bounce sideways even with the 50lbs of shot on it. Took me a few shots to figure that out so the lower holes would have touched. The upper ones did.
