When I was running a 338 Lapua I used 96grs of Retumbo. This moved a 225 gr accubond out @ 3100 fps out of a 26" barrel. I used this as a hunting rifle one year. I shot an elk @ 450 yds and a moose @ 70 yds. Both animals were hit in the chest cavity, elk broadside and the moose straight on. Niether bullet exited the chest. Killed them dead right there but didn't exit the chest. My theory is that the 338 accubonds were built for the 338 win mag at a slower speed and are acting like a ballistic tip from the lapua. So I quit using accubonds and am running Barnes as my only hunting bullet now. This is just my experience, and maybe the accubonds have improved but I won't use them again. Don.
