Just recieved my order of 255 grain Flat Point Hard Cast for the 45 ACP and 45 Super by Buffalo Bore
Overview
45 ACP+P
45ACP+P ammo is externally/dimensionally identical to 45 ACP ammo and can be fired in any 45 acp firearm that is in normal operating condition. However, the greater pressures and power of the +P ammo will give you greater slide velocity and if you are going to shoot more than a box or two of +P ammo, you should consider replacing your recoil spring with a Wolf Spring that gives roughly 4 to 6 lbs more spring weight than factory stock springs. A shock buffer might also be a good addition although it is not too necessary if you use the stronger spring.

The below velocities were fired from my personal Colt Gold Cup 1911 (5 inch)

1. 45185-----------1180 fps (185gr. Jhp)
2. 45200-----------1078 fps (200gr. Jhp)
3. 45230------------979 fps (230gr. Jhp)
4. 45230FMJ------981 fps (230gr. Fmj-FLAT NOSE)
5. 45255------------960 fps (255gr. HARD CAST-FLAT NOSE)
And the 45 Super
45SUPER

45 Super is externally/dimensionally identical to 45 acp or 45 acp+P and is designed to be used in 45 acp semi auto pistols that have been fitted with stronger than normal recoil springs and a shock buffer, plus a couple other modifications. While you can shoot 45 SUPER out of some stock 45 acp+P pistols such as the Glock 21, HK USP or the full sized all steel 1911, you will batter your pistol if you do not have them modified to handle the extra pressure and slide velocity of the 45 Super.
All our 45 Super ammunition is loaded with flash suppressed powders so that if you have to fire in low light (when the criminal element is out) you will not be blinded by your own gun fire at the worst possible moment.

To learn about the modifications your 45 acp pistol needs to reliably and safely fire 45 SUPER, contact Garey Hindman at 936-402-3484. Garey is the foremost authority on 45 Super modifications/conversions for your 45 acp and Garey performs such conversions for a living.

The below velocities were fired from my Colt Gold Cup Govt. Model (5 inch) that was converted by Garey.

1. Item # 45S185-----------1330 fps (185gr. Jhp)
2. Item # 45S200-----------1235 fps (200gr. Jhp)
3. Item # 45S230-----------1131 fps (230gr. Jhp)
4. Item # 45S230FMJ----1133 fps (230gr. FMJ-FLAT NOSE)
5. Item # 45S255-----------1090 fps (HARD CAST-FLAT NOSE
The performance brings the 1911 to an even higher level on the food chain
I shot 2 of the 45 Supers and one of the 45 ACP and to my surprise they shot to the point of aim and cycled through my pistol perfectly. More testing to follow

springs

I have one of my 1911s set for use with .45 Super. I have a 28lb. recoil spring in the thing. I don't believe that is enough. I am ordering a 32lb. spring from Wolff.
It does shoot a lot flatter if you try it plinking at 100 yards.

I use the stock spring with the barrel slide lock up mated to stay locked longer alowing the pressure to lower before unlocking.

A 255 grain bullet at 1075 FPS is viable for Boar hogs with a grissel plate

Neat! I like the sound of those loads.

I find the EGW square bottom firing pin stops do more than anything else to limit muzzle flip and reduce apparent recoil. They work by reducing the mechanical advantage of cocking the hammer, which delays unlocking. They make the slide harder to rack, but a super stiff recoil spring will, too, and the flip reduction from a spring change is less than from the stop. If you have trouble racking the slide with the flat bottom stop, unlike a stiff spring, simply cocking the hammer eliminates the extra effort. I'm thinking of one-hand emergency reloading here.

A good source of high quality recoil springs and shock buffers is Sprinco. I think their springs only go up to 20#, though. Their buffers (they call them Recoil Reducers) are well made.

Springfield Long Slide V-16 in .45 Super.



I`ve often wondered how much extra velocity you get from the longer barrel. But I don`t own a chronograph, so I`ve never had the chance to check it.

It depends on the particular bullet and powder, but, in general, it is between a 4% and 5% velocity increase going from a 5" to a 6" barrel in .45 ACP. Since MV goes up as the square of velocity, the average is about 10% ME increase.
