Finally, let's put this to rest. From what I have read, the 300 Dakota may achieve a 2-8% increase in water case capacity over the 300 Win Mag. - 1. 300 win. mag. (90.4 +- grains) vs. 300 Dakota at 97.0 +- grains Is this worth doing? I am looking for efficiency and beltless case (if possible). Ideally, if this translates to 100fps more velocity on average, I think it might be worth it??????
