So I did a ladder test and while shooting I didn't notice these faint ejector marks but once I got home I did. It was sunny and due to the light I just couldn't see them. They started to appear at 42 and 42.6 grains. Some cases had them some did not, My velocities were inconsistent but I believe that is due to my POS Pact scale. I think they were loaded inconsistently because I had pulled several bullets and weighted the power, many were -.1, some were -.2 from what they should have been.
Can I shoot them again? Is the rule of thumb that if I can feel them with my finger nail that should discard them or just use them for practice? It could affect head space I suppose.
What maximum vertical dispersion should I expect at 600 yards with the following 308 load?
175 grain Nosler Custom Comp
Between 41.4 to 44.2 grains of AR-Comp
Velocities 2732 to 2879
Lapua Cases
BR-2 Primers
OAL ~2.810 (6 mil jump to the lands)
At 44.2 grains I started getting prominent ejector marks.
These were shot out my Savage FTR in 308
Thanks guys and gals, your experience is invaluable
