The big projectile got all the juice the RS was giving up. I am not surprized. The energy needs to go somewhere. The bigger grained powders really shine with big projectiles.
You may be right about that. Next time. I'll use some RS with the 385's and see how they chrony with 70 grains RS. And I'll try75 grainsPyro P with the 410's. Dang this is fun!
