[QUOTE="Jud96, post: 1860967, member: 69478"] Load work up and pressure testing is complete with the .308 Norma Magnum, Berger 215 Hyrbids, RL26, and Norma brass. I started seeing a slight ejector mark at 71.8gr and it was just noticeable. I decided to continue working up to see how high I could make it before the ejector mark became more pronounced and until I got a stiff bolt lift. The ejector marks looked the same from 71.8 to 72.8 and there was a nice node there. I do not like loading at these pressure levels and only continued working up for data. At 73.0 grains I felt a stiff bolt lift and a shiny and more apparent ejector mark was present. I called it there and ended my load work up. I was very happy with how well these 10 different loads shot! All of them went into that ragged hole and this bullet is showing promise! My second photo is my charge and velocity notes. The third picture is the 71.6 grain load showing no pressure and the final is the 73.0gr load showing pressure signs. I see a couple potential nodes in my data. My next step is to load 5 rounds at 71.4 grains. That is right in the middle of a 0.4gr wide node and 0.4gr below where I first saw pressure. I’ll be testing that load looking for less than 20FPS extreme spread and single digit standard deviation. I’m thinking velocity will be right at 2940-2950, where I originally sat my goal for this bullet.[ATTACH type="full" alt="D97A6135-119D-472F-98A8-3D93A5DE8A82.jpeg"]183580[/ATTACH][ATTACH type="full" alt="A92810E0-489B-427A-846E-D6FC8F255302.jpeg"]183579[/ATTACH][ATTACH type="full" alt="B930AED2-95B7-4359-9A4E-515B7D822111.jpeg"]183581[/ATTACH][ATTACH type="full" alt="A7991FD3-3E5A-4882-89D8-76CC04464C0B.jpeg"]183582[/ATTACH] [/QUOTE]
