RL 19 does it for me.
51gr. under a 145 Speer HC, PPU brass, Fed 210 primers. 2790 fps, 1” groups at 100 meters from my 23” custom barreled Ruger 1A. Perfect (for me) on deer sized critters. The only 7x57 load that I bother with.

What man, on his death bed, ever lamented, "God, I wish I had spent more time at the office."
