I recently picked some RL17 up and worked up a load for a 30-06/165 NAB. It gave me a great (.8") group at 0.5 grains under max. As well as a RL22 .25-06/100 NBT.
But now that I'm tooling up to reload for another cartridge (.260 Rem.) I've been "crunching numbers" in all the different manuals and the RL series consistently comes up short in velocity to conventional powders (H4350, H4831, etc) as well as needing to take up 1-4 grains extra just to get that velocity.
So what are the benifits of this line of powder supposed to be? Is it more resistant to temp/humidity changes or something? Lower case pressures? Alliant doesnt have any chamber pressures on the site..
