Just a guess PP... but I'd bet a buck that the highest velocity for most of those handgun calibers can be found at CorBon.

"At COR®BON, we believe that velocity is king! Higher energies enhance bullet performance and increase stopping power."

For 9mm it would probably be the Hirtenberger L7A1. Cheap pistols ran the risk of failure with this ammo.

+p for .45 I would assume would be hot.

I have some but have not shot any in comparison to win. white box or pmc.

I will crony a bunch and let ya know.

I am Meh on the whole must have hot rounds line of thinking!

For 9mm it would probably be the Hirtenberger L7A1. Cheap pistols ran the risk of failure with this ammo.

You mean the "Winter Sub-machinegun" ammo?

Washington--The Bureau of Alcohol, Tobacco and Firearms (ATF) has been
advised by Hirtenberger AG, Hirtenberg, Austria, that certain 9X19 mm
caliber ammunition produced by Hirtenberger is unsafe for use in any
handgun.

The ammunition, designated L7A1 and produced ln the years 1990 through
1992, was produced for the British Ministry of Defense specifically for
use in submachineguns under adverse conditions. The ammunition was loaded to produce pressures far in excess of that intended for use in handguns.

The manufacturer advises that up to 12 million rounds of this ammunition
has recently been sold on the world surplus market. The ammunition can be
identified by the following head stamp located on the bottom of the
cartridge case

12 O'clock position: HP
3 O'clock position: 90, 91, or 92
6 O'clock position: L7Al
9 O'clock position: the marking of a cross within a circle

This ammunition should not be fired.

I shot some of this 124gr ammo a few years ago in my P7M8... recoil was sharp for a 9mm, but no snappier than say a 125 grain CorBon.

Fun with guns...

Possibly somewhere to look is at the buffalo bore brand of ammo. They make most all standard chamberings and almost all are plus p rated. Check midway.com for particulars. Also midway publishes the velocity of the ammo brands/loads they sell.

I have always been a fan of doubletap ammo.

Whatever he's using.

PP, it's not the speed of the round if that's what you mean by hottest. It's the amount of energy that's dumped into the target ie good expansion and weight retention vs full penetration and exit.

I saw a site not long ago that rated handgun bullets by test. I'll go look for it. It even had pictures of the spent bullets and energy measurements.

Edit. Here's one. <broken link removed>

9mm? Probably Atlanta Arms and Ammo "355 super"

Made for 9mm major power factor USPSA Open guns, it's dimensionally
identical to 9x19.

124 gr HP jacketed, I chrono'd some out of a G17 without barrel ports
at 1405 fps. Runs around 1360 out of my G17 open guns with three
blow holes and a 5 port compensator.
