I am with Trailhound, the 338 mag, perhaps more than any other cartridge needs to be handloaded to get the full range of use out of it. You can reproduce loads slightly lighter than 3006 factory all the way up to something generating 3500 ft lbs of muzzle energy with 275 gr bullets, and not have a lot of trouble getting accurate loads through out the entire range. I have even shot roundballs in a 338 mag, run a 36 caliber ball through a 338 cast bullet sizer and load it on top of five grains of bullseye with a filler and you have a 60 gr bullet at about 500 fps. Good for close range squirrels and like sized backyard varmints. Extremely versatile cartridge for the handloader!
