I have found accuracy to be pretty close with both, they are both excellent. I expect it is fair to say that the Interbond will shoot at least as well as the SST and the Accubond will be at least as accurate as the Ballistic Tips. They are somewhat different in retained weight objectives. Hornady is striving for the high 70's to low 80 % retained weight, with expansion initiating and well underway in about four inches from impact. Nosler is going with slightly lower retained weight and at least as quick initiation of expansion.
Which is the more accurate bullet? Very tough to say, would be determined by your barrel. I have been getting sub 1/2" five shot groups with both. Have shot a lot of 150 and 165 Interbonds in the .308 Win. and the 200 Accubonds in my .300 WIn. and also another fellows Savage heavy barrel. The 200 Accubonds tracked almost perfectly with 200 Sierra Match Kings out of his rifle out to 1000 yards and they were amazingly accurate all the way.
Nosler originally entered the market with fairly heavy bullets in the Accubond line, intended for big magnums and big critters. Hornady went with lighter bullets with their Interbonds and they are obviously after deer sized critters.
Was told that for some reason, some of these bonded bullets are actually shooting better test groups than comparable non-bonded from the same manufacturer.
Newest .30 cal bullet is a wicked looking 180 Accubond from Nosler. Have them but have not shot any groups yet, too **** cold.
