[QUOTE="DoneNOut, post: 2360705, member: 113404"] I think you are correct in your hypothesis about ball powder. I have just come to expect ball powder to produce more velocity. AA2520 vs Varget was the last comparison in a 35 Rem and AA2520 was 90fps faster with less pressure sign. The downfall, however, is the variations in velocity with temperature swings. I try to load develop everything in the summer temps, but especially the ball powders because the pressure spike with hotter temps can come quick. If I am stuck winter load developing I keep the rounds warm against my body until I chamber. [/QUOTE]
