Glad to see my bullets are still shooting well for you. Your grouping is pretty typical of what I and others get with rifles from a 1-20 to 1-30 twist bbls. Also depending on what White I shoot either 70 or 75gr of 777-3F seems to work best for me as well. As soon as the weather breaks a little I'm going to some Swiss 3F. I use to shoot Swiss, but its been so long I forget what load I was using.
I guess what Grouse said could happen, but with the wide flat metaplat I don't think that happened, but who knows. Sometimes the ML God's just like to mess things up on us. GRIN
