In my Remington Mtn rifle with 22 inch barrel, 58 grains of H 4831 gave me an average velocity of 2890 fps at an ambient temp of 90 degrees. Federal 215 primers, Hornady spire point.
57 grains of RL22 gave 2939 fps on the same day at 90 degrees, with the 215 primer and the Hornady Spire point.
Took a cow elk at 425 yards with that load, and bunches of deer with results that were totally satisfacory, at least to me.
I have data in my notes that 57 grains of H4831, 150 Interlock, 215 primers gave me 2700 fps in a different barrel.
