I prefer the 338 FED to the 358 WIN too. About the only thing that a 338 FED can't do that the 358 WIN can is shoot 0.357" handgun bullets, but that is only an advantage if you think that shooting handgun bullet from a rifle is useful.
I’ve had a few 358s > BEFORE the 338 F was produced.
The 358s did well with 180 gr Speer bullets but POOR bc.
I killed quite a few deer with it within its limitations.
Today I’d NOT think twice about getting a 358 ! 338 Fed w/o a doubt.
Good luck w/yours and I hope it shoots well for you.
