My last 270 Bee did 3500 fps with 76 gr of IMR 7828 and 130 Hornady Interlock. No 270 win I know of can do this.
I don't doubt the 7828 data but when Hodgedon re-worked the loads they reduced most of them. This was true with the 7RM. When I asked a technician he just said different rifles so I don't know if early lots were slower or what.
