New Alloy

I believe that your assessment is correct. This is from some one that nearly 40 years ago, when the wisdom was, Sharps rifles used pure lead bullets, built his first long range load using 103 grains of DuPont Fg powder and a 30/1 PP bullet with a felt wad. I know all about nose slump and base cupping. When I tried that load with 2Fg powder my 500 yard group size nearly doubled and I could hardly keep my shots on the 22" 500 meter gong. I returned to Fg powder but started using 20/1 alloy.
How is the patch separating from the bullet? Is the rifling cutting long strips even though the rifling is not marking the bullet, unwrapping, or just blowing into pieces?
