Re: Hornady Critcal Defense Ammo

Gold Dot non +P shot through heavy cloth into water.

I don't see an expansion problem relating to clogging. :headscratch

It does appear that in most modern hollowpoints, some degree of temporary clogging when shot through cloth occurs, delaying expansion only momentarily, providing for additional 1-2 inches of penetration. This is a good thing.

I've got some old jeans around. Reckon I'll soak up some newsprint shortly and get to the bottom of this.

Re: Hornady Critcal Defense Ammo

If a round passes the four layers denim FBI test, I don't worry about clogging to much.

Maybe that is a mistake on my part. I sure would like to know if there is an acceptable failure rate among the FBI and others who utilize the same data.

Hornady Critcal Defense Ammo

Hornady is promoting the latest stab at the perfect bullet with a claim every Critical Defense bullet will expand on target penetration due to a special polymer insert in the bullet tip which prevents clogging of the hollow point cavity by clothing and later aids in symetrical expansion.

The company admits to some sacrifice of penetration to achieve that 100 per cent expansion rate, as well as lesser performance by FBI testing protocol in some materials like windshields and steel.

The latent Holy Grail here seems to be energy dump as it relates to hydrostatic tissue shock. Certainly not a bad thing, and probably the single most important causative factor behind the fabled "lightning bolt effect" of the 357 MAG.

The energy dump theory has been downgraded in some circles as a major factor in incapacitation. But incapacitation/stop rates in police shootings increased dramatically wherever the Super Vel hollowpoint ammo replace ball rounds. What's your take on this?

I was unaware that clogging is a significant problem with modern hollow points like the Speer Gold Dot and Federal HST rounds. Again, experience and comments on this very important issue?
