My personal experience is with ABs in 30cal on many species. My experience is that they are predictable. I'm not sure where the comments about lack of penetration come from, if whatever cartridge you are shooting at a given range can't get adequate penetration with a mushrooming bullet, I'd question the choice of cartridge and not bullet. I've seen multiple cases of pass thrus on elk 500-800 yards. Someone stupidly took a rear end shot with my rifle on a whitetail at 400 yards and the bullet nearly came out the front, with everything in between destroyed.
It is my second hand observations of VLD performance which has prevented me from having first hand experience. With Bergers shot by hunting buddies, I've observed inconsistent and sometimes explosive performance even at extended ranges where the velocity effects should be mitigated. This was on antelope, deer, and mule deer, so I would expect the results on elk to be even worse.
Just my opinion, but based on what I've seen I'll stick with ABs.
