accubond was designed for a narrow mushroom and 70% weight retention. interbond makes a much larger wide mushroom and was designed for 90% weight retention.
First, what any bullet manufacturer tells you their bullets will do does not mean they actually do that.
Is that 150 grain 30 caliber Whizzbang Gamedropper going to produce the specified mushroom and weight retention when loaded in a 300 Savage that shoots an elk through the ribs at 200 yards, versus loaded into a 300 Weatherby magnum that shoots a whitetail through the shoulder blade at about 30 yards?
The bullet manufacturers are really up against it. Things have gotten better over the years, but they have no control over the range of velocities and the huge differences in game animals their bullets will be used to put in the freezer. Look at the upper and lower end muzzle velocities that .30 caliber hunting bullets might be used at, while at the same time 30 caliber rifles have shot everything from tiny coastal deer to huge coastal grizzly bears. Sometimes using the same bullet.
And then the bullet is supposed to deliver exactly the same expansion and weight retention, whether on a ribs of a scrawny whitetail out at 300 yards or through the shoulder blade of a bull moose called into almost spitting distance.
You can pursue The Perfect Bullet to the end of your career; you'll have fun experimenting and shooting as you develop loads, if nothing else. I preferred to stick with finding a bullet that performed reliably in all my hunting rifles and stuck with it. That bullet sure as hell wasn't a Hornady. Not after digging two bullets out of a bull elk that almost got away, that looked mostly like blunt pencil erasers rather than an expanded hunting bullet, despite those first two shots being at about 50 yards where they had more than ample velocity to allow them to expand.
Maybe Hornady had a bad day the day those bullets were made. Maybe it was a bad lot. But I'll never load another Hornady for hunting big game, even though I'll happily agree that bullets can change a lot over the intervening 45 years. For varmint shooting, plinking, whatever, sure, Hornady's were the most accurate bullets going in my AR15 - but I didn't hunt big game with that rifle.
Find a bullet you have confidence in and stick with it until you have reason not to any longer.
In days of need... use what you can get your hands on or beg, borrow, and steal from your friends.
