I do not have personal experience with the Woodleighs in .375", but I have seen the 286gr Weldcore 9,3mm exspand willingly even with 9,3x57 velocity. For what you are looking for driven hunts you should might consider the Brenneke TUG. For Buffalo I guess the standard Weldcore .375" 300gr is too soft, after the Informations I have heard and seen.

You state that you find it difficult to shoot the second barrel for game nummer two if you havnet seen the first one roll. To my etichs you should never shoot the last bullet to a fresh game! The meaning of a doubles is the quick follow up shot....

What you describe after the shots in Poland I would personatly not find acceptabel! Every shot taken should be controlled with tracking dogs, polish hunting organiseres will not learn this etichs unless you as a Hunters (read customer) demands it.
