As bad as my eyes are going now days I can still tell the difference between a .458 mag case and a necked down .416 Taylor case from the .458. Don`t know where you saw Taylor brass for $3 a case, only time a case head stamp of correct caliber to a rifle would be needed if going to a foreign country that is picky on things like that. I`ve been making cases for my Taylor for a few years now using Hornady Basic 45 mag. cases. These are an overly long case that can be trimmed down to any of the Winchester long mag cases. I have an .375 H&H as well as a Taylor, yet I use the Taylor much more. Never made it to Africa due to life`s happenings, now too late for me physically.Robert
