think you may have already answered your own question with ""shoots great and I love it"...

Agree with everything said here...338 on plains game is awesome and you would not be disappointed...

The idea of having the 375 for and additional weapon in the event your .458 went awry is a good idea..plus your odds of any shots much past 150 t0 200 in Zim are low..

Personally, as you are hunting BOTH plains game and dangerous game--and will shoot the plains game in all likelyhood much more than the dangerous game gun--I would take the .338--but that is just me...either will work just fine...

Boddington once wrote he thought the perfect combo was something in the .375/416 range along with a 338 for the light gun...think that is very wise advise..

Good Luck

See you in 3 weeks or so...
