I would vote for .300 Win Mag or 300 WSM followed by .338 Win Mag. They have good performance, a wide variety of bullets and factory loads but the .338 is a heavier recoil which makes it a little less desirable IMO. The short mags are great especially the .300 WSM because of great ballistics and bullet availability. I would love a .325 WSM but the bullets aren’t made by all the popular companies.
