Does a cannelure on a bullet hold it together better than a bullet with out it ?
Will a bullet with a cannelure penetrate better than one with out it ?
I use Sierra bullets and have never recovered one from deer so i don't know if they came apart when i hit my game.
It is usually a mess inside so i don't dig around in them!

The cannelure on a bullet is for a crimp, If you have a tube feed and you do not crimp the bullet will get pushed down into the gun powder, Hi power pistols also need to be crimped as the recoil will let the bullet slide out of the case. I have seen no advantage to either way, as i use both kinds in various rifles.You still must hit the vitals.
The Hornady Interlock is named so because the cannelure forms a crimp into the core. These cores separate just about as readily as any cup and core bullet. I wouldn't say that the cannelure does anything significant in terms of terminal performance.
Depending on which Sierras you're using, I don't doubt that they are coming apart, but I've never recovered an Accubond from a deer and I'm confident that the reason is not that they "came apart". Sure, they shed some weight but the majority of the bullet kept going.
If you want penetration, buy a bonded, partitioned, or mono bullet design... or load heavy for caliber cup and cores at modest velocities.
