[QUOTE="MagnumManiac, post: 1693370, member: 10755"] I just went through several pages of my previous years notes shooting F-class with 6.5x47, 264WM & 300WM. (Yes, I am old school, I still use belted mags in comp) Prior to mixing my powders, H4350, H1000 and RETUMBO would show significant lot to lot variations. As much as 100fps in either direction. After blending several lots, including 3 8lb kegs of H4350, the largest variation in velocity swings was just 20fps. This is vastly different to the change from one lot to the next. H4350 was by far the worst for lot to lot variation. Oh, so was Varget early on in my SR F-class rig in 22-250AI. So, if anyone says that blending will cause higher ES, they're talking out their butt. As I stated earlier, if you blend PRIOR to working up loads, it it what it Is, you may just find a more stable blend as I have more so than not. Cheers. [/QUOTE]
