Something I've noticed regarding all the nay saying about 458 Win is that the ones who tend to make the most noise concerning it's problems are also often the ones who have the least amount of experience with it and in some instances they may actually have none.

I'll stir the pot a little here and say that I'd be happy to leave that Thys as a 458 if it were mine, shoot the hell out of the thing on targets and non dangerous animals, see how reliable it is, then make a decision.
