Bullets were cast from a mix of Rotometals hardball and 16-1 that results in a ratio of ~94.6/2.7/2.7. They were air cooled and then aged about 3 weeks prior to sizing to 0.310” and loading. Lube is Carnauba Red 2700+. They were not sorted in any way.
The first shot flyer in the first pic is after wiping the bore with Hoppes #9 the night before. All shots are listed in order of firing.
In this last pic, the two shots to the upper right were shots 2 & 3 of the string and were my fault because I moved the rifle in the rest away from where it should have been placed. There is no data on this string also, but I think the first two indicate that it is a pretty consistent load. The Chrony evidently didn’t like where the bullet was going through the screens. The load is slightly compressed, coming halfway up the case neck. As before, I chronograph at the 50 yard line at this range because of ease of use. Not much should be inferred from these groups other than that they are consistent.
