The 357 Herrett was designed to perform at it's best in a 10" barrel. It should perform great in a carbine length barrel, but the 35 Remington will probably be a better all around cartridge and the brass is much easier to come by. Don't get me wrong, I love the 357 Herrett, but it's original purpose has been outdone by the times. I have 2 Contender barrels in 357 Herrett, but would'nt recommend a 357 Herrett over a 35 Remington to anyone. The only advantage is the rim, which makes it much easier to extract in a pinch.
If you don't mind fiddling with a wildcat, then the 357 Herrett is a lot of fun, which is why I have two, a 10" and a 14".
