Just starting load development formy 300 RUM in a Remington Sendero.
Using retumbo to start with. Have loaded them at 50 thou off lands and are 3.900 COAL. Shot good, just doing some fine tuning. Was wondering where everyone was having the best success? Close to the lands or more of a jump.This thing has a pretty long throat in it.
Just trying to sped the process up, its kind of a pain in the A## right now, we can't shoot in my back yard cause the snow is still to deep.
