[QUOTE="Howland, post: 1698932, member: 103509"] I had the same issue with .338LM. I was using H1000 and the best accuracy was a very modest charge but ES was horrendous, over 200. At first I thought insufficient neck tension in combination with a low powder charge was the culprit so I picked up some custom mandrels to tighten neck tension. While it improved accuracy a bit and the ES got a little better, it was still unacceptable, over 100. Knowing I now had optimal neck tension I repeated the OCW test. I found a node with very low ES and sacrificed a few tenths MOA. At longer range the lower powder charge accuracy would never have held up anyway. [/QUOTE]
