Woody, If you are planning on using the Hornady 140 XTP for deer hunting beware,
That bullet is really much to fragile for the speed it will come out of a rifle barrel.
Try to find some ammo loaded with the 158 XTP flat point bullet , Not the hollow point.
I have seen the lighter XTP HP's fail many times on deer sized game, Im sure it would work on a perfect double lung shot but you can never count on a perfect shot angle when hunting and you dont want to chase a wounded deer all over.
Get you a tougher jacketed bullet or some flat nosed cast bullet ammo and your .357 mag will do fine.
