JimRau The 358 Winchester short is made by taking .2" off the neck of a 358 Winchester case.
The Hoosier is a little more work and I think a better case. You are taking a .1" out of the case neck and .1" out of the case body. The short takes it all out of the neck. Leaving you a very short neck of only a little better than .15 to hold the bullet.
Don't get me wrong it will work and people are using it. I just feel better about having more neck like with the Hoosier.
There is also a guy that is doing the same thing with the 350 Remington Magnum that was dun with the Hoosier. He is claiming that he can get the same results as the parent case ballisticly. Me personally I think I will be sticking with the Hoosier. It takes deer cleanly and I have never been one to chase that extra FPS out of a load. As I said before I don't like max loads. To hard on equipment and the shoulder. It has been proven time and time again that the sweat spot for killing game is between 2200 to 2800 FPS. With a good bullet and a properly placed shot.
