Problem was, the spin of the bullet often flung the material out of the bullet cavity long before reaching the target.
Bob, That actually makes a lot of sense. Assuming 1,000 FPS (357 magnum is probably going to exceed that) and 1 in 16 inch twist the bullet leaves the barrel at 45,000 RPM's. That is a lot of centrifugal force.
