At 308 velocities you need a bullet that will mushroom, your impact velocities are much lower than a 300 win mag so don't shoot the same bullet. Match your bullet and impact velocity and game don't just grab a bullet, I very rarely would say to shoot a BT however it's the same bullet as the accubond without the bonding, an accubond will quite mushrooming much earlier in the process which is not what you need at 308 speeds, at 300 mag speeds way different story.
Inside of a half hour I watch a 168 and 165 Barnes fail to penetrate the chest of cow elk, I shot one with a 168 from a 300 WBY, dropped her and she looked dead so we ran down the line and my freind shot a cow in the center of the shoulder with a 30-06 and a 165 Barnes, it broke her shoulder but did not penetrate into the chest, I called for a shot behind the shoulder as she was hobbling around which killed her. We then saw my cow was trying to get up so I ran over and cut her throat, my elk was 400+ his was 230 yards, my bullet broke her shoulder and then turned out the front of the shoulder my buddies just mushroomed and stopped.
What we've figured out with shooting these overly hard bullets on elk is that you have to maintain enough impact velocity that the bullet shank can force it's self through an over sized mushroom. The hard bullets create a huge amount of frontal area which is why they are them stop or deflect without a significant amount of momentum behind them.
I used to subscribe to the "elk bullet" theory till we started shooting elk on open pivots, a 100+ a year, there was an undeniable trend with having to shoot elk more times when using copper or bonded bullets. Ten years ago I went back to a regular cup and core bullet, I have not had to shoot an elk twice since with the exception of when I tested a copper bullet out again, on two elk and a mule deer I shot on elk and the bullet deflected but still broke its neck, the second elk and mule deer both needed dispatched due to 3/4 inch wound channels.
I will absalutely still shoot copper or bonded bullets but I certainly would match them to the rifle and game, I have yet to see a bullet that will do the same job across the board.
