The 338 guy could say the same to the 30 caliber guy and so on and so on.
I think there is a balance between cost, recoil, knockdown, trajectory etc. It sounds like thats 30 caliber for you and that's fine. However it doesn't take away the merits of the 6.5, 270 or 7mm. I have used a 7mm to kill bison, elk, deer and all fell dead on the spot.
You would be and, are very much mistaken.
Unfortunately, I have no favourite, but people arguing that the 28 Nosler is somehow magical and covered with pixie dust gets up my goat. It is no more accurate than many many cartridges out there.
I often use 338WM, 340Bee, 338 EDGE & 338-416 Rigby Improved. Then I might take my 375 Weatherby, 375 AI or a 416 variant of some description.
I am, in fact, a huge 264 fan, own several 264WM's, 6.5x47's and 6.5-284. Have owned a 260AI & 6.5-06.
I am not in the Creedmoor fan base, probably never will be. The merits of the cartridge are fine for steel or paper punching, but LR hunting should be left to smallish deer, coyote and similar game. That is my opinion, right or wrong in others eyes....I don't care.
I limit my own 6.5x47 to 600mtrs and on small deer, goats, pigs & foxes here Down Under.
There are plenty of guys here using them double that distance with very good results, but the risk of wounding game, for me, is far too high.
Just my opinion from 30 years of hunting, shooting comp & LR range hunting/shooting.
Cheers.
