So I just did a small ladder test with my AT-X. I'm getting heavy bolt lift on what I believe to be pretty mild loads. I'm also noticing weird markings on some of the case shoulders. No real signs of pressure otherwise (please double check me on this). I'll post some pics.
6mm Creedmoor
107 SMKs
Lapua Brass
CCI BR2 small primers
H4350
Charges were 40.5, 40.8, 41.0, 41.2, and 41.4.
Velocities were under 3100 fps
The brass was new and I sized it with a SAC sizing die prior to loading.
