[QUOTE="JLDavid, post: 2425008, member: 27557"] I went and shot again today. 30° and full sun with just a hint of left to right breeze. I used fully prepped brass again but I did change to some old CCI 250 magnum primers. I dropped my charge weights some just in case I was going to be closer to pressure with the primer change. I loaded test loads of 65.9, 66.2, 66.5 and 66.8 grains of 8133. 65.9 and 66.2 shot even better than 66.5 did last session, well under .5MOA. Velocities for 65.9, 66.2 and 66.5 averaged 3055, 3060 and 3060 fps with ES of 21 and SD of 10. This is from a small sample so I am pretty sure I have not solved the ES/SD issues I was having unless I shoot a larger sample. [/QUOTE]
