Well, the only Alliant powder I've used is RL22 and I was never all that impressed by it. Maybe I just wasn't using the right combination. I'm going to give it another go and see what happens. Might try some RL25 too.

I think in order for a powder to work well at 1000 yards it must produce low standard deviations in velocity. Velocity differences probably don't show up much on paper at shorter ranges, but way out there I'd think it wouldmake a lot more difference. Even though there may be lot to lot variations, the SD produced by each lot could still be quite low I suppose.

I'm really not sure why I'm so interested in this. Just bored I guess. Long range shooting is not something I'm particularly interested in. At the rangesIdo 99.9% of my shooting, just about any decentpowder (appropriate for the cartridge)would probably work for me.
