My 2 favorite 338s are the 338-06 and in some rifles the 338 federal.

If I want more power I am a devotee of the 375H&H.
I have yet to shoot anything that covers the bases was well as the 375 let alone better.

I have owned a bunch of others too. 325 Win Short mag. 338 W. Mag. 358 N. mag. 375 Weatherby. 416 Taylor (3 of them). 416 Rigby. 404 Jeffery. 458 Winchester (4 of them). 460 G&A.

But the one I still have (which is now on it's 2nd barrel) is the 375H&H. Over the last 20 years I have sold all the rest.

I am going to make myself another 404 because I liked the old own so much, but I have not really missed all the others very that much. I liked them all, but the one I love is the 375 H&H Mauser I still own, and will never sell.

If I ever make another 338 for myself I am sure it will be either on the 06 or the 308 shell. I like the bullets from 200 to 225 grains in that bore size, and higher velocity is of no real use to me for the game I hunt at the rangers I hunt them.

The 338 Win Mag is a very popular rifle here in Wyoming, and I have made a lot of them. I have a high degree of respect for the round. But for me personally, I like the 375 better.
