I've always been in awe of the big 338 rounds. They're potent long range hunting rounds. When I first read about long range hunting the 338 Edge shooting 300 gr Sierra bullets were all the rage. Now the Edge is hardly mentioned. New developments are mostly 308 caliber and below. With the advent of higher BC bullets and faster twist rifles, 284 and 308 calibers now do what the 338 Edge used to do. The new standard seems to be the 300 NM AI with 245 Berger or similar bullets. Even the big 284s with 195 Berger or 180 ELDM are potent long range rigs. The smaller calibers recoil less and are probably a bit easier to shoot well while giving up little ballistically.
For big, thick skinned, or dangerous game, 375 caliber and above are more appropriate that 338, 8mm, or 358. For extreme long range target shooting it's also 375 and up. Smaller calibers will never compete ballistically at extreme distance or up close at something dangerous.
Those tweener calibers are deadly and effective but unnecessary for 99% of shooting.
What development if any could turn this around?

You would think that those above .308 would have a much larger following!
