Just my opinion , but I think there is a threshold of increasing caliber where frontal area starts to make a difference in killing power , and maybe that starts at some wheres between 35 caliber and 375
at any rate , the Whelen will mostly drive bullets of equivalent sectional density to the same speeds as the corresponding lighter bullets in the 338 , for example , the 225gr 35 caliber will equal the speeds of the 210gr 338
the extra weight and frontal area should result in somewhat of an increase in hitting power
on the other hand the superior b.c. of the 338 bullets may result in more retained energy at distance
so , would really be hard to say there is a clear cut winner......
