No problem answering this one. I had my own wildcat .416 before the Taylor came out. I simply opened up the .300 Winchester Magnum case to .416 and had a P-14 Enfield barrelled to fit. It will do anything the Taylor will do and a tiny bit more. Easy brass availability, no problem duplicating .416 Rigby ballistics. I have a picture of it around somewhere I can forward to Dale to post. Very satisfying to shoot.
