Few weeks ago, I decide to utilize ball powder H335 which I had, and used for .223 but now I decide to use it with .308, so I been tweaking this load and it seems 43.5 grains of H335 was most suitable for me 2760 fps sound reasonable with 155 grain Nosler Custom Competition bullet. So here is picture of the target I shot today at 100 yards, groups on the right are marked Unknown since I couldn't find what powder I loaded, I packed them sometimes last year for hunting season, that was one shot deal. I think I used IMR 4064, which is awesome powder and I have load already developed just for it, 5 shot groups stay within 0.3" - 0.4", The one on the bottom is probably Reloader 17, no matter what I do with it it does this fliers. So you think with H335 I reached the end in the load development or there are more room for improvements?
