I had good luck with H450 in my m77 7x57 using 139 and 154 hornadys.Too bad it is no longer available.
That H450 must have been some wonderful stuff. It appears on almost every page of my older Hornady loading manual. That may a slight exageration. When I was younger, my neighbor gave me a pound of the stuff leftover from his reloading phase years prior. Stupidly, I poured it on the sidewalk and lit it thinking it might be too old, or something. It was black and shiny and smelled like every other powder, but I burned it anyway. I regret that smooth move.
Our God reigns. Harrumph!!! I often use quick reply. My posts are not directed toward any specific person unless I mention them by name.
