RE: TAYRUS 454?????
If I was in the market for a 454 I think I'd have to go with the S&W 460XVR. It's going to cost a good bit more, but I think worth the extra money. It is capable of firing 45LC, 454 Cassull, and 460. The 460 is a 200 yard capable round and extremely potent on just about anything up to elk and maybe bigger depending on range.
