Barber, sorry about this being a late post. If you bought the .357 Super Mag, and are using it for hunting, be careful of the bullet selection you use. A friend of mine, back in the late '80's, or early '90's was using the Hornady XTP in 158gr. Had a good hit on a deer, and it didn't penitrate. Blew up on the shoulder. Thought I was seeing things. Deer hesitated for a second, then took off. We found hair, and a little blood.
About a year later, talking with a guy at a gun show in Indiana, he related just about the same story. He was using a T/C with a 10'' barrel, so was probably gaining about 100/150fps over the D/W. The deer ran towards this guys hunting partner, and he killed it. Upon examinition, the shoulder wound was superficial. Chunk of meat, and hair missing, but no entry wound.
I know that some bullets have improved in the last 10-15 years, but you might want to check out other posts on these bullets. Gypsyman
