Helping a friend, he only loads handgun. I load 30-06, he shoots 308. He provided the supplies.
Federal brass trimmed to 2.005 per hornady
Hornady 150g sst bullets
Cci standard large rifle primers
H4895 powder
We tested start to max with no pressure signs loaded just below max col at 2.810. I used the hornady bullet seat Gauage, I don't remember the measurement but it was around 0.030 off the lands
Looking today hornady recommend seating that bullet at 2.735. I tried it but got compressed load at 40.0g and I struggled to get consistent seating depths. Also the cannalure is below the neck and not visible at all seated to this depth.
My plan is to go back to the 2.810 seating depth tomorrow and see how case fill is and where compression starts. Since I know I have ok jump.
I don't mind compressed loads. But if it's messing with my seating depths I don't want it.
I feel like a beginner. Something seems odd. Is this a bad powder choice? Could hornadys data be off? The cannelure being below the neck and not visible seems wrong.. What am I missing?
