There is more difference between the 338wm and the 30-06. .030" from 30-06 to 338wm. .037" between the 338wm and the 375's. Moreover, that difference in diameter is magnified in area.
Also, Federal lists the 250's at 2660fps or less, not 2750fps. I doubt that Federal loads the 338 down, or understates their load's performance. The 210's run 2830fps - not 3005, the 180's 3120.
The difference in trajectories is almost nothing between a 225 TSX and the 210 NP, at Federal's realisticaly achievable velocities, .3", .8" and 2" at 300, 400, 500yds, or 1/10th MOA, 1/5th MOA and 4/10's MOA. Impressively, the difference between the 210 and the 250 NP's is only .8", 1.8" and 3" at 300, 400, 500yds, or less than 1/4th MOA, 1/2 MOA and 6/10ths MOA. 200yd zero assumed for the differences noted above.
Except on the internet, MOST RIFLES AND SHOOTERS CAN'T ACHIEVE 1 MOA, AT 100YDS!
