Hodgdon / IMR SR4759
If anything, a wee notch slower than Vihtavouri N110, SR4759 has generally good availability, its primary attribute, and is best used only for 250 grain bullets. About 42 grains is a reasonable charge, with a cautionary note. Poor Hodgdon / IMR quality control has resulted in up to 200 fps lot-to-lot variations.
Several shooters like this powder, but if you change to a new can from a different lot, you had better bring your chronograph to the range with you. You may have to go down two full grains to eliminate sabot damage, or go up two full grains to get the same performance as before. The lot to lot consistency makes it not worth my time these days, particularly when hunting out of state. A new can of this stuff can be a brave new world.
