In the 7mm Rem Mag, .300 WIn and, now, .270 Weatherby this has proven to be one of the best powders I've tried. Velocities equal or exceed that produced by other powders and accuracy is better than most. BUT loading data seems to vary a lot for this powder. 7mm Rem Mag loads were barely over the book minimum when I hit 3000 FPS with 160 gr Partitions and quit. I did fire a couple rounds that were 2.5 gr over the book minimum and gor ejector marks on the brass. In the .300 Win Mag and .270 Weatherby, the loads producing a reasonable velocity vary from book loads (both higher and lower) more than with other powders I've worked with. Load manuals also seem to vary a lot. Anybody else have this problem with H1000? TIA, Ward
