What is the purpose of bonded ammunition in .223 for self defense purposes?

Is there a benefit in using a bonded bullet?

Thanks

Bonding keeps the core and jacket from separating. This means the manufacturer can make the bullet expand at a lower velocity without the bullet fragmenting and thus not penetrating far enough.

Bonded bullets rock, they give excellent wound channels and deep penetration, and are very consistent, which is very important on a marginal caliber like 5.56.

Keeping bullet weight up generally means better penetration.

Thanks much for the replies

Bonded bullets help keep the core and jacket together increasing penetration, very important in light weight bullets like the 223.

I shot a small buck a few years ago with a Federal 62gr Fusion load out of a 20" AR.. Quartering towards me at just under 50 yards. Dead before he hit the ground. Not even a slight twitch. Hit him in the near shoulder bullet passed just behind the shoulder bone, stopped in front of the diaphragm, just under the skin on the far side. Bullet fell on the floor when we skinned him. Very nicely mushroomed. Perfect bullet performance IF you don't want fragmentation. Bonded bullets will give you more penetration in general, better barrier performance in general, will not come apart. Probably can expect little expansion at long range/low velocity.

Bonded bullets stay together better against hard surfaces.... auto glass , as an example.

Otherwise, considering the small bullet size of the 223, I do not feel that it is beneficial in most cases.

OK

I figured it had more to do with hunting than self defense

Umm, I want the same performance from a hunting bullet as a SD bullet (other than barrier).
