With the additional material, our brass is heavier than most other manufacturers brass and therefore will require lower charge weights to achieve the same pressures and velocities due to the reduced volume inside the brass. We recommend using a reputable load data source and working up from their recommended minimum starting loads. Failure to reduce charge weights established using other manufacturers brass will likely result in higher pressures and velocities while using ADG 6.5 Creedmoor brass and may result in unsafe pressure levels.”
I was aware of that. I used lower charge weights than I had previously used with federal brass. I saw pressure earlier but with lower velocities over my magnetospeed than I had with federal brass. At 41.6 gr h4350 when I blew a primer I was only getting 2730 fps. I'm going to verify all my measurements and start fresh.
