RE: .357 for deer
The 357 is a great deer cartridge. when fired out of a 6" barrel, it generally has a range of about 50 yds. 125 gr. bullets are great for broadside shots, but often won't penetrate a shoulder bone.
Handloads extend the range of the 357 on deer sized game considerably. CorBon offers a 180 gr SP that is good on deer out to 100 yds.
357 carbines are about as effective as a 30-30 on deer inside of 125 yds. And in my mind, the 30-30 is one of the best deer rounds ever.
