Anyone care to recap this?

They found when using Doppler Radar that the Ballistic Coefficient changes with polymer tipped Ammunition. They developed a polymer tip that does not deform and gives long range hunters better long range consistency.

Brilliant marketing!

Well said! The tip of the bullet gets hot and deforms in all polymer tipped bullets except for the one that they've just developed. Melting tips create drag and slow the bullet down. Their tip increases accuracy, terminal velocity, and cavity expansion over all other polymer tipped bullets. They claim they've created a match grade hunting bullet.
Yeah, and now the only question remaining is price/availability.

Many years ago there was a study that concluded that the base of the bullet was more important for accuracy than the the tip.

True, as long as the tip doesn't deform during flight and induce tumbling due to asymmetrical drag. If I read the article correctly, their new polymer tip doesn't deform (as much?).

Im sure you can sell them to some cheap @ss.
BTW, I've got some bronze tips that seem to do the exact same thing as the new polymer. I'd check them myself for deformation art terminal velocity but my damn doppler's in the shop.

Thanks for posting, i really enjoyed that!

Im a firm believer that feed geometry and how smooth the transition from the magazine to the chamber effects consistency.
If Hornady found that deformation of the tip effected things then rough feed geometry and rifles that damage projectiles should apply as well, I would think....
I have performed ramp work on precision rigs and shooters have noted they saw some improvement in their groups. Most of them are AR type platforms.

So I was a little curious about their claim of ballistic tips and for kicks ran the numbers. Assuming a bullet is going 3000 ft/sec at sea level standard atmospheric conditions what would be the temperature at the tip of the bullet (stagnation point)? A 3000 ft/sec bullet is going Mach 2.69 @ 59 degrees F. That gives a temperature at the tip of about 810 degrees F.
So yea I could easily see how that would melt most polymers. The problem is, what are they going to do about their A-max and V-max lines? I wonder if they are going to update them with this new high temp polymer.

How did we ever get along without polymer tipped bullets?
