I recently loaded my 300 RUM with a 200gr. ELD-X bullet, Retumbo powder for 3,000 fps with a 600+ BC . for some Long Range shooting.
The results were above and beyond my expectations, this is a great load for my my Remington 700 Long Range and the load is nowhere near max.
So there is still more room to experiment with.
Accuracy and Energy , what more could you ask for.
