When the .338 Win. first came out, Winchester offered a 300-grain load for it as well as a 200 and 250. I am not certain that anyone ever offered a 300-grain bullet for handloading, but Speer at one time did furnish a 275-grainroundnose for the .33's. But it was discontinued years ago. Probably right after Elmer Keith died-don't think anyone else ever bought any!!

I do not know of a 275 or 300-grain .338 bullet available today, either as a component or in a loaded round, except for that Swift-A-frame at $55.00 for 50! I think a .338 solid in 300 grains would make a great load for African game!
