Both my .280s shoot the 140 gr Accubonds well. They have been my go-to for hunting. I decided to try and load up some 160 gr Accubonds in an effort to realize a potential elk load. I ended up with 58 gr of IMR 7828ssc, 20 thou off the lands. The rifles seem to like the load. I did not fool with seating depths as I just went off the same depth as the 140s, which do well. Surprisingly, the 160 gr groups were very close to where I have the 140s hitting. I didn't fudge with the dials, was just looking for the speeds and good 5-shot groups. 58 gr of 7828 gave me a 10 shot ES of 5 and respectable five-shot groups. I did not achieve the 3010 fps I was hoping for, but only reached 2925 with this load. Both rifles were 26" barreled Browning X-Bolts.
