Thanks for all of the advice!
Now that you have your mind made up, let me throw this at you
A 300 RUM shooting a 210 SMK @ 3150 fps will hit harder than a 338 WM shooting a 225 AB @ 2950 fps, at all ranges and out of the muzzle. The ballistics (trajectory, wind drift and TOF) are also a lot better.
1000 yds 300 RUM, 1901 fps, 1686 ftlbs KE, 57 lbft mom, 48" drift/10 mph wind
1000 yds 338 WM, 1587 fps, 1259 ftlbs KE, 51 lbft mom, 66" drift/10 mph wind
700 yds 300 Rum, 2237 fps, 2334 ftlbs KE, 67 lbft mom, 22" drift/10 mph wind
700 yds 338 WM, 1943 fps, 1845 ftlbs KE, 62 lbft mom, 29" drift/10 mph wind
The 338 does have a larger frontal area, but the 30 cal is plenty big enough to do more than adequate damage and the 300 RUM beats the 338 WM hands down on the charts.
I hope your head isn't hurting
