I think SurvivalShop is on the right track here given what we have to work with up to this point.

The different loads produced different nodes and anti-nodes along the barrel, and as the barrel harmonics changed the whipping of the barrel changed as well and your ladder group reflected that.

Ladders are what we all grew up with I know, but you might check out out Dan Newberrys work, he's the guy who came up with the "Optimal Charge Weight Load Development" system.

I've run through it a few times and was happy with the results, I know a lot of long range guys use it, its really quite simple and it really does tune your barrel in and help you find the best load for consistent accuracy.

Hope that helps. ;-)

There are three threads in the reloading section about this topic. Read up boys. Whole lot of information to be had.
