5 Good .45 ACP Loads

Man Shooting 1911

The .45 ACP is my favorite handgun cartridge. I have to get that out of the way before I begin. Just the same, I have an open eye and mind, and I am not blind to other developments.

The .45 ACP was developed to offer a reasonable substitute for the .45 Colt, save in a self-loading action.

The .45 Colt had been designed to give troopers a fighting chance and to drop an Indian war pony at 100 yards.

The cavalry was an immensely important and influential department of the Army when the 1911 and the .45 ACP cartridge were being developed.

The .45 ACP was actually developed much earlier and chambered in the 1905 Colt. Standard performance was a 230-grain FMJ bullet at 830 fps.

The Colt soon earned an excellent reputation for stopping dedicated adversaries.

The .45 ACP wasn’t designed for civilian personal defense in the beginning, but for use against warhorses and hardened fighting men, it did the job well.

Interestingly, among the original requirements was that the cartridge be useful against dangerous animals such as Jaguars.

The Army had serious problems with bears and wolves as they moved out west, and many of the early rimfire and .44 cartridges were very weak.

The .45 Colt, and later the .45 ACP, offered real power without excess recoil.

A great deal of development went into increasing accuracy potential in the time between the World Wars, eventually giving us superbly accurate handguns.

Ammunition development stalled at times. Some of the hollow points introduced in the 1970s would feed or they would expand, but not both.

Today, we have well-designed bullets that offer excellent feed reliability, even feeding in old GI guns for the most part.

A modern bullet with a good balance of expansion and penetration considerably increases the wound potential of the .45 ACP cartridge.

Let’s look at five good loads because best is a relative term. Some loads are best for one purpose or the other, but the loads that I trust and carry in my personal firearms are general-purpose loads.

They are useful for the worst-case scenario and accurate enough for any chore.

While there are differences in the performance of these loads, be certain that the difference in shot placement would count for more than the differences in expansion and penetration.

As it turned out, these loads are similar in general performance. There is a consensus on what is needed in a personal-defense cartridge, based largely on FBI testing.

These loads are among the best I have tested in some time.

Les Baer 1911
The Les Baer Hemi was used in accuracy testing.

1. Speer G2 230-Grain Gold Dot +P

The Gold Dot is among the most proven personal defense and service loads in history. Speer recently improved this formidable loading.

The new design features a hollow-point cavity filled with an elastomer. The new bullet also features reinforcing ribs for the petals.

There is no longer a Gold Dot at the bottom of the cavity, but the bullet is space age.

The elastomer is designed to prevent the bullet from being plugged with clothing or intermediate material and failing to expand.

The Speer Gold Dot Generation 2 +P breaks 916 fps from a five-inch 1911 and 870 fps from the four-inch barrel Springfield Champion Operator.

I tested expansion and penetration using water jugs. Sure it isn’t gelatin, but it gives a good comparison between loads.

The jugs are six-inches wide so penetration is easily measured, and the bullet penetration was tagged at the spot in the water jug it came to rest.

The Gold Dot Generation 2 penetrated 18 inches and expanded from .79 to .81 inch. This is ideal performance.

I would be hesitant to use the load in a lightweight frame or Officers Model, as there is greater recoil. A standard Gold Dot loading may be preferred at about 840 fps in a Commander-size pistol.

For those wishing to maximize the .45 ACP, this is a great load.

2. Hornady 220-Grain +P Critical Duty

This is another +P load. Don’t worry, the steel-frame 1911 will take it. I fired a five-shot 25-yard group for accuracy in the Les Baer 572 Hemi.

The result was a 1.25-inch group for the best results, and a 1.65-inch average for three.

This wasn’t an accuracy contest, all of the loads are accurate enough for personal defense, but that is impressive precision.

By dropping the standard weight slightly to 220-grains, Hornady has managed to combine standard recoil with high velocity.

The average from a five-inch barrel is 1040 fps. Penetration is 16 inches and expansion .70 inch. The leading water jugs were blown off the table.

Hornady’s Critical Duty is a good service load.

3. Winchester 230-Grain JHP

This is a general-purpose defense loading available in 50-round boxes. It is affordable, reliable and accurate enough for most uses.

A standard-velocity loading is useful in short-barrel or full-size handguns. This load was also tested in the GLOCK 21 with good results.

The Winchester load is no slouch for a non +P, clocking a solid 855 to 866 fps in full-size handguns.

With 18 inches of penetration, this loading expands to a consistent .70 inch.

Winchester’s 230-grain JHP sometimes lost its jacket, but expansion is good.

4. Fiocchi 230-Grain Extrema

There are two Fiocchi loadings, one a 900 fps XTP loading and the Extrema at 840 fps. This load offers modest recoil in comparison to a +P, and has excellent accuracy.

Fiocchi features high cartridge integrity. The 230-grain Extrema breaks 840 fps in most pistols, 855 fps in the GLOCK 21.

Penetration is 20 inches and expansion .68 inch. The 900 fps load, in comparison, averages 18 inches of penetration and .72 inch expansion.

I prefer the standard-velocity load when all is considered, and this one gets the slot among the top five loads.

Target with .45 ACP Bullet Holes
This cluster was fired from the Les Baer with the Fiocchi loading.

5. Remington Black Belt 185-Grain

I wanted to test at least one 185-grain loading. The Remington Black Belt is based on the Golden Saber, a proven design.

The Golden Saber uses the expansion of the bullet jacket as a wounding mechanism.

The Black Belt design features a driving band on the base of the bullet to increase accuracy, and a band in the bullet to prevent fragmentation.

This loading breaks 1003 fps in a five-inch gun and 976 fps in the Commander. This bullet penetrates 16 to 18 inches and expands to .73 inch.

Felt recoil is modest. As a defense load, particularly in lighter-weight .45s, this is a good choice.

The Black Band Remington exhibited excellent results.

.45 ACP Loads: Conclusion

The .45 ACP has been called the hammer of the century. The .45 is a good cartridge, but if you do not practice, build skills and use good tactics, no firearm will save you.

These loads are good choices and among the best modern loads.

  1. Jaguars, and wolves and bears oh my. The legend is growing. I just read about the requirement of the 45 Colt to knock down war ponies. Now bears and jaguars. I am a fan of the 45 acp. Won’t be trying it out on bears, horses or jaguars. Maybe in the Super configuration on hogs.

  2. I have carried 1911s in .45acp for years. I my water jug tests I have had excellent results with the 200 grain Sig V-Crown JHP load and have made it my eery day carry ammo.

  3. The newer solid copper loads from Underwood have all but rendered the hollow point bullet obsolete. The Xtreme series ( Penetrator/Hunter/Defender) do not require expansion like a hollow point, thus negating the potential for hollow point failure. You have the penetration of a hard cast projectile and the design creates a wound channel greater than any hollow point. This is the future of ammunition.

  4. I have found the stories of feeding problems on old 1911’s overblown. I own an original ww2 Colt 1911A1. It has never failed in all these years I have owned and fired it , to feed and eject anything I have fed it. That includes Mil spec rounds, low power target loads, hollow points , and lead bullet loads.

  5. I have a Llama 45 made in Spain it has double stack clips,I’ve had it for several years.
    I live in rural SE Alaska lots of Bears around, what bullet would you recommend ?
    Thanks for you’re input
    Mike

  6. I, too carry the Polycase Inceptor ARX in both my Springfield Armory mil-spec M1911A1 and my S&W M&P Shield 9. And as I’m getting older and my eyes aren’t what they used to be, I have Crimson Trace lasers on both. I like the ARX for its lateral dispersion of rotational energy as well as reduced recoil and flash. The lightweight, high-velocity ARX produce more energy than most, but as a backup I also have the Speer Gold Dot and Federal HST.

  7. There is no question that the 45ACP is a superb defensive and tactical load. While I have always had a “love affair” with the 1911 in both the full size and Commander sized variants, my one complaint has always been and continues to be the limited magazine capacity of the 1911. For over 20 years, I worked as an armed private contractor in Las Vegas before moving to the part of the country that I live in now. During those 20+ years, some of the details I accepted were considered to be High Risk and High Threat assignments! It became readily apparent to me that I needed a tactical handgun cartridge that provided both high terminal energy and threat-stopping capability in addition to a higher cartridge count in the magazine! After the 1986 “Miami Massacre” occurred, the FBI determined the 10mm to be, by far, the superior tactical cartridge for its agents!! As a result, I gave it a try and have never looked back! Yes, there is considerably more muzzle blast in addition to more recoil and muzzle-flip so yes, more time is absolutely required to be spent behind the weapon for training and practice! But consider this: a full-sized Glock Model 20 incorporates a 15-round magazine which is more than double the capacity of the standard 7-round 1911 magazine! A 155 grain 10mm Gold Dot hollow point loading by Underwood Ammo provides more than 700 ft. pounds of threat-stopping energy at the muzzle in addition to velocity that creates an enormous wound channel!! If concealment becomes an issue, the sub-compact 10mm Glock Model 29 still provides a 10-round magazine in an easily-concealed weapon!! In this man’s humble opinion, what the FBI determined back in 1986 still holds true today; the 10mm is the superior semi-auto tactical cartridge that provides incredible threat-stopping capability!!

  8. The 1911 was designed to shoot hard ball so that is what I’ve stuck to for all these years. Never had a problem with feeding or accuracy issues that can happen with hollow points. My thought has always been, if something is hit with a 230 grain projectile, no matter how it’s constructed, and refuses to go down, shoot it again.

  9. for self defense I like federal hydrashok, I reload 45acp using 185 grain hornady xtp bullets and 7.5 grains of unique powder. I built a bullet stop in my backyard using 6, 4″x4″ and 5/4 lumber on both sides filled with dirt. out of my thureon defense 16″ carbine my reloads go right through it. luckily there is a huge hill right behind it

  10. Great article on the 45acp… gotta say it’s my favorite auto round… 44mag/special is my go to revolver round … thanks for the review of the ammo & feedback from others

  11. I just had to comment when I saw SECUNDIUS say he shot hot loads in his Singer 45. If it really is a singer and has all matching parts it is worth TONS of money and should be babied and never shot. One of these examples went for $414,000 at auction.

  12. I carry a Glock 21 in both 45 cap and 400 Corbin (a Jarvis barreled conversion I made – and yes it functions reliably) and Mac-Tech in 45 Super (though the brass is impossible to find). The outer dimension of the acp and super are identical so I just use relatively hot acp loads. My favorite is a cast 200 grain SWC over 5 grains of Red Dot. You can’t use this in a factory barreled Glock; but Jarvis barrels are just fine and the Mec-Tech loves it

  13. Exsoldier I did some research and was wondering if a 460 Rowland will feed in a Colt officers or Defenders .45Acp. I saw that it’s longer and won’t feed. Also who’s your gunsmith of choice in South Florida? I don’t know of a good one down here. Thanks.

  14. I’m partial to the .460 Rowland, which has nearly twice the stopping power of the .45acp and works well in virtually every .45acp pistol/handgun…

    1. I thought about getting a Wilson Combat 1911 in 460 Rowland and then Wilson discontinued the model. Did some research and discovered that the 10mm offered all the advantages of the 460 Rowland but less expensive and more available. I picked up an EAA TANFOGLIO Hunter Elite with a 14rd magazine (bought 5sp mags) and a six inch barrel. A hot 45 auto +P might squeeze out 450 foot pounds of muzzle energy. Battering the gun. A decent 10mm load from Buffalo Bore will easily reach 750 foot pounds of muzzle energy. I had mine ported by my favorite custom gun smith in South Florida. His three holed punch midway down the barrel makes the recoil of a vociferous 10mm feel like a 9mm +P. If I want something lighter, I go with a Taurus Tracker 44 magnum in a two inch barrel. That beast generates about 1000 foot pounds of muzzle energy. Very stout recoil and not for the novice shooter, which I am not.

    2. @ EXSOLDIER.

      Which is all good and well IF you own and/or want a 10mm Pistol, which I don’t, and don’t have any plans to do so in the foreseeable future. For my Singer .45ACP, I use .460 Rowland’s and for my 9mm I use 960 Rowland’s…

  15. Ex Soldier

    We must be brothers!

    I sometimes carry the Springfield Hellcat in this sweltering summer heat, sometimes along with a Chief’s Special on the ankle.
    But like you if travelling the .45.
    In the wild either a heavy loaded .45 Colt SAA or Smith and Wesson .44 Magnum.
    Stay safe!

  16. I have been stacking ammo in both my 1911’s, except when I am out in the woods for years. Long story about that and we don’t have time or space, I have multiple reserved mags loaded with Black Talon and Golden Saber for critters like pigs, feral dogs, etc. that I may encounter out there.
    My EDC magazines are stacked with G2 Research’s 162 gr R.I.P. and D.R.T. 150gr Terminal Shock ammo. There is significant reduction of recoil compared to the other rounds I have used for EDC in the past, like the aforementioned Black Talon and Golden Saber. (I realize that is a subjective report, but it feels lighter to me.)
    I like the groups with the R.I.P. and D.R.T., and the overall feel. Don’t shoot those much as they are not cheap. For practice, I have several other rounds, to include some Wolf brand , Blazer, Magtech, and Perfecta, all in FMJ. I shot everything else up. I am down to around 1,000 rounds of those. Going to be time to order some more soon.

  17. I’ve had remarkable success with the Polymer ARX load in terms of accuracy and relatively low recoil/low flash. When I carry my Sig Sauer RCS 1911, that’s all I load. I’ve been an NRA Instructor for 32 years and carried mostly the 45 auto concealed much of the time. Now, being fully retired and living in East Tennessee, when I stay in town I tend to pocket carry a Sig P365 9mm but when I must traverse the Appalachian Mountains I’m ALWAYS armed with a 45 auto. Minimum. Alternates include an EAA Tanfoglio Witness Hunter Elite in 10mm with a 14 rd magazine. Also I carry a 44 magnum when Trout Fishing in Bear Country but I wouldn’t feel “underarmed” with a 45 auto and the Arx load in Bear Country.

  18. One of my favorite concealed carry handguns is my Kimber ultra Raptor and I use Underwood
    45 ACP +P 120gr Xtreme Defender 1420fps , 537ft lbs and is incredible shooting
    Makes a Statement for sure

  19. I’d like to see the Polycase/Inceptor/NovaX in the mix. After watching many tests this appears to be a contender not only for it’s significant increase in speed and increase in ft lb but carry weight alone is significantly reduced. The the design allows for a 114g projectile to be pushed at speeds nearing +p 9mm loads but with a larger projectile. These are my carry rounds in 9mm and 45acp. It would be nice to see any ballistic comparison with the current loads you mention. There is no question the Gold Dot, HST are staples in the LEO profession but I feel there needs to be serious research into this type of round for LEO duty carry. I see many benefits and anytime you can reduce weight on the person you gain endurance and reduced fatigue. IMHO
