I'm trying to come up with a light recoil load for my sons new 7mm 08. I figured the 120g Nos BT would be a good choice so i loaded a few up with 44g of IMR 4350. That should be a pretty light load but I'm finding flattened primers. I used Winchester brand brass and CCI large rifle primers. I'm confused to why i'm seeing pressure signs when starting at the bottom of the chart. Can anyone shine some light on where i've gone wrong?
