And when you have a 338cal bullet going the same speed as a 30cal bullet of the same kind,which on do you think will have the bigger whoomp when it hits?
Your logic is still flawed.
#1 You're not considering Sectional Density. The 30 caliber bullet in the same weight will always penetrate deeper regardless of range assuming the same bullet and shot placement.
#2 In this case the difference in 3/100" bullet diameter is about the same as your fingernail. Not enough to matter.
# 3 Even if you compare a 200 gr 30-06 at 2650 fps MV to a 200 gr 338-06 at 2800 fps MV, nobody shoots stuff at the muzzle. At only 100 yards the 30-06 has almost caught up to the 338-06. By 200 yards it has equaled 338-06, beyond 200 yards the 30-06 beats it in every way. While both have more than enough punch to get the job done at close range the 200 gr 30-06 has almost 200 ft lbs more energy at 400, plus the ability to penetrate deeper. And since the 30-06 started the same bullet weight 150 fps slower recoil will be considerably less.
#4 If you compare 338-06 to 300 WM both shooting 200 gr bullets to the same speed the 300 wins in every category at the muzzle; and the gap only gets wider as range increases. And since you're shooting the same bullet weights to the same speed the 338-06 will recoil virtually the same as 300 WM. If I have to deal with the same recoil anyway then I might as well get the advantages of 300 WM.
Not to say the 338-06 won't work it obviously will. But it doesn't offer a single advantage over 30-06, we're splitting hairs regardless. And when you consider that there are people killing elk at 1/2 mile with 243's it seems pretty pointless to argue about 338-06 vs 30-06.
