I have been using the accubonds since I could get my hands on them. A little over a year now. I have been an avid fan of Nosler for 25 yrs. I read recently that the accubond was designed to preform like a partition and loose 25-40% of the frontal area. The reasoning is that if too much of the bullet is retained the the mushroom gets so large it won't penatrate deep enough. I have heard that this happens with Hornady Interbonds. So if the nose is shed the diameter stays small enough to do the job. And it does do the job. Took a mature 3X4 Idaho Mulie with the 160 grain last Oct. Hit him through the chest quartering away at about 200yds. The bullet took out a rib on the near side then the heart, blowing through another rib on the far side leaving a 2" dia. hole to bleed through. He immediately went down, tumbling 25yrds down hill DOA. I was impressed! No bullet recovery though it ended up somewhere across the canyon.
The load I use is 64.5 gns of RL22, Rem case, CCI 250 primer. Clocks an ave muzzle speed of 3025 through my Chrony. I get a .75" group at 100 yrds.
This should work well on elk but I use a 338 winnie for that job with barnes X bullets.
