A year or two ago a buddy of mine (LEO) got one of the earlier 396's. It was capable of handling the pressures, but had gas cutting something severe when using Pearce's loads. We found the cast didn't work near as well as the jacketed for accuracy, and it was heck to hold onto as well. A steel gun stands out in my mind as to having big advantages when trying out these loads. The newer ones are a bit heavier, and should bite a bit less. They are not heavily made, and my buddy still has it, but gave up on a SWC heavier load for his purposes. The gas cutting was dealt with by Smith, but we've not pursued the loads since then.
