Ran a ladder with 108gr Hornady ELD-Match bullets. The pulled bullet in the top left was my fault. I have velocity data, but still need to get it from the ProChrono.

Very nice!

After shooting all 40 rounds, I did not see any swipe marks or anything resembling over pressure. Need to anneal the 40 rounds. Will reload another 10 round ladder of 28.5, 28.7, 28.9, and 29.1gr of CFE223. Will shoot from 100yds so I'd expect more drift.
