I began center fire deer hunting in 1972 and have hunted Ar. La. Miss. & Al.
All together of the hunters and handloaders I've met there is a TOTAL on ONE (1) person who had a 264 WM. He also is one of many I introduced and got him involved on handloading.
That says something on the popularity/obsolence of the 264 WM.
Personally I have not one thing against the cartridge.
