While I took the time to give Mr. Gibson the answer he asked about regarding what alloy he might use to test round using GD, even though I did not understand why he would ask such things, being that his past experiences should have answered such a question, I reckon Mr. Gibson is pretty capable of figuring out where to start with alloys at the GD velocities offered in the Alliant data.
See post #23 for my "short" suggestion on what alloy to use.
