Tee SST will INDEED separate the jacket and core on a solid body hit . If you take The classic through the ribs shot, it'll most likely hold together---but you'll never know, it's out the off side never to be seen.

The IB on the other hand, will never loose it's jacket. It can't! The jacket is bonded to the lead. Weight retention is 85% or better when fired into water jugs @ 100 yards.



That's a 165 .308 IB from my 300 WSM @ 100 yds, 3125 fps MV.



That's whats left of a 154 SST from a 7mm mag. jacket and lead fragments just under the hide on the back side of the front shoulder of a 150 pound yearling whitetail. Jacket and fragments weighed 70 grains IIRC. Range was about 75 YDS.



Bullet barely visible, did NOT exit the deer.

You'll get a bigger mushroom with an interbond. That limits penetration just a bit, BUT the increased weight retention balances out.

Noslers accu-bond has a smaller frontal expansion, but looses a lot more weight. Retention is around 65%.
