No. But I strongly urge that you get a 458 LOTT and not a 458 WINCHESTER if that is possible. The Lott is to the Winchester like, say, 22 Rimfire Long Rifle to 22 Rimfire Short.
The Lott will chamber and fire BOTH in total safety, for the Lott is no more than a slightly longer 458 Winchester will give higher velocity in factory cartridges or, if you reload, the same velocity at less pressure.
But you probably already knew this.
