Big Game Round Help Needed

[GIJOE]

I have decided after eye burning computer studies that I will forget all of the afore mentioned rounds and go with the .300 RUM in my ole Winchester M1917 action. The small amount of energy advantage the larger rounds have over the .300 RUM at the muzzle are soon obselete and the .300 rum is holding its own or surpassing the larger rounds at 200 and 300 yds . I don't believe I even need to comment on the trajectory .Its looking like I will be using the .300 RUM for just about all of my hunting needs except for quail , there hard enough with a 20 gauge.
