Hauptjager,

The Interlock Hornady's have a locking ring formed inside the jacket towards the base that holds the core from slippage (usually) as the bullet mushrooms. The InterBond on the other hand has the core bonded or soldered to the jacket. Done correctly this is by far the best.

I have a box of the new .416 InterBonds and they look might stout! Jacket material is a brass or bronze alloy and thick! Almost 1/16" thick! My only test so far has been in some gnarly green Cottonwood which likes to pull jackets off. The bronze beauty retained 90% of its 400 grains.

I would use a Woodleigh 270 grain Weld Core Protected Point .375 for your sheep if it were me doing it. This is a bonded core bullet as well that will open well and stay together well and shoot well all in one package. I really like the .416 340 grain Woodleigh Protected Point as well.
