H870 was the powder to use in my 7mm Rem mag with heavy bullets till I tried RL 26 some old manuals used to show H870 one load at max easy to load for and usually accurate and fast and dirty.
That was my first 7mm Rem load. 80-81 grains of H870 and a 140 Partition. Not sure how fast it was but man it shot amazing. Used that load forever.
