Based on that info. PICK ONE AND BE HAPPY!!!!
For those critters at those ranges, you are straining nats at this point. Both have similar recoil (bullet weight for bullet weight) both have similar barrel life (a slight favor to the 300) The 7mm RM will typically have higher BC's again, bullet weight for bullet weight. the 300 has the option for heavier bullets as well as more types, weights and shapes to choose from. The 300 will have less radial torque than the super fast twist 7mm. The 300 will push equal bullet weights faster versus the 7mm RM.
Pick whatever makes you warm and fuzzy all over. Either will suffice.
