Who makes the hottest .45 acp ball?

Not counting the specialty manufacturers like Buffalo Bore.

When I am talking hot, I am not talking blow up your gun hot, I am looking for the hottest within SAAMI or CIP specs.

It may depend a bit on your specific gun. However, I just watched a video recently by Paul Harrel, and W-W white box tested high by a bit in all 3 guns he tried.
 
Problem with looking for a "hot" 45ACP load is that most 45 ACP ball ammo is loaded to the old military specs, so deviation between companiwes is low due to the standard of 230 gr FMJ at 850-900ish fps. Companies like CorBon and Bufflao Bore load them hot, just most don't due to the most common firearm they are chambered for, the 1911 pistol.
 
old military specs
It was not 850-900 fps. I read a contract specification sheet dated 1968 (while I was in Vietnam) and the velocity was specified as 830 fps, +- 15 fps. That gives a range of 815 to 845. Original Ball from 1911-1912 was claimed to be 820 fps. A year or so back I chronographed current production Federal Ball and it was ~865 fps so some of today's Ball is hotter than original.

I have to say I do not understand the need or desire for the "hottest ball". The 1911 and the 45 ACP cartridge made its legendary reputation for stopping with standard pressure and performance Ball ammo, however YMMV!

From TM 43-0001-27, ARMY AMMUNITION DATA SHEETS, SMALL CALIBER AMMUNITION FSC 1305 dated April 1994, page 8-13,

Cartridge, Caliber .45, Ball, M1911:

Use:
Submachine Gun, Caliber .45, M3A1; and Pistol, Caliber .45, M1911A1. The cartridge is intended for use against personnel.

Description:
BALL Cartridge. The cartridge is identified by the plain bullet tip.

Propellant:
Type ------------ SR 7970
Weight---------- 5 gr

Performance:
Chamber pressure----- 19,000 psi
Velocity ---------------- 885 ± 25 fps, 25.5 ft from muzzle

That compares with current SAAMI specs for the 45acp of 21,000 psi and 45 acp+P of 23,000 psi.
 
Many sources I have seen over the years list GI ball as 830fps +/- 30fps, but either way its a small number of fps and you can get that much, or more variation from individual guns, so "850fps" is not unreasonable as a general number.
 
I think it was Cor-bon about a decade or more ago that made a 185gr. load that was advertised as turning your old 1911 into a .357 magnum. the photo for the Ad was fmj in the magazine.
 
You wouldn't notice the difference between 15, 25 or 30 FPS anyway.
"...am looking for the hottest..." What for? Just curious. Accuracy is far more important.
Is your pistol rated for +P? Hornady loads a 230 grain XTP with a MV of 950 FPS out of a 5" barrel.
 
I'm not particularly an expert,and I could be wrong...

But since you specify "Ball" ,here are my thoughts. Hardball just punches a hole. Typically ball is 230 gr. The ammo manufacturer s limited to < SAAMI max pressure.

I doubt any target will notice the small velocity advantage any non-boutique factory load will give you. You might gain a small percentage of barrier penetration.

It might be good to select a load proven reliable in your handgun,but 35 or 40 fps just is not significant return .
 
"Ball" in 45 ACP being most often considered target ammo, and prone to serious over penetration without much tissue damage when used for SD, why the interest in who makes the hottest?
 
BE CAREFUL!!! Unless the entire case is suportted,

you may blow the case out of the 1911 type barrel as the feed ramp does not
fully support the case.

the .45 ACP is capable of one shot stops BUT you have to place in correctly.


Continue using standard hardball and practise at a bowling pin shoot, to work on shoot placement.

possible with any round but rarely an issue with .45ACP.

"Standard ball" is rarely allowed at bowling pin shoots due to the hard round nose tendency to "skid off" the rounded surface of the pins.

If you want the "hottest" 230gr FMJ around, go get a .45 Win Mag. 230gr @ 1500fps! :eek::D of course, there's no free lunch, the guns are bigger, heavier and more expensive...
