1873 was a landmark year for cartridge development, giving us two pivotal designs that remain popular to this day: the .45-70 Government, and the .45 Colt. The Civil War was over, and the westward expansion was booming. Firearms had gone through radical developments in the last couple of decades; the large caliber muzzleloading rifles had given way to the breech-loading metallic centerfire cartridges of smaller diameter, which gave a much faster rate of fire, as well as unprecedented reliability.

Developed as a joint venture between Colt Firearms and the Union Metallic Cartridge Company, the .45 Colt was introduced in the Colt Single Action Army—which would be known as the ‘Peacemaker’ of Western fame. In 1875, it became the standard issue for the U.S. Army, and remained so until replaced by the .38 Long Colt in 1892, though it wouldn’t be long until the Army adopted yet another .45 caliber pistol cartridge, but you know all about that one.

The .45 Colt—or .45 (Long) Colt as it is irritatingly known—was originally loaded with 40 grains of FFg black powder, under a 255-grain lead bullet, at a muzzle velocity of just over 875 fps, as has been shown by testing original loads over a modern chronograph. This made for a very powerful combination, and for the stuff of legend. The combination of the Colt Peacemaker and the new cartridge gave what was at the time the most power a cowboy could put in his hand. Yes, Winchester’s release of the .44-40 in the same year as the Colt gave it some stiff competition, as the Winchester ’73 rifle and the Colt Peacemaker were both chambered for the smaller cartridge. Having both a handgun and rifle that can effectively use the same ammunition made things very convenient for the pioneer/homesteader/cowboy, but the military adoption of the .45 Colt made ammunition regularly available. The combination of Colt’s pistol and this cartridge would be the title of a Western movie (starring Randolph Scott, in 1950), as well as the name of a Major League Baseball team. Few cartridges can claim that!

The .45 Colt is a semi-rimmed design, in that in comparison to the .44-40 or the .44 Magnum, its rim is slight, measuring 0.512”, while the case body measures 0.480”. It is a true straight-walled cartridge, having no taper whatsoever, and it is sparked by a standard large pistol primer. In recent times, the cartridge has experienced a resurgence, in both its original conformation, as well as a much-improved hunting cartridge. The Colt Single Action Army pistol, and its clones, can only handle a certain pressure, while the modern handguns - like my personal favorite, the Ruger Blackhawk—can handle much higher pressures, bringing the .45 Colt to unprecedented levels. My own Blackhawk, with its 7½-inch barrel, will drive the modern copper-jacketed 300-grain bullets to over 1,300 fps; we’ve got an entirely different animal at that point in time. My pistol will put five 300-grain Hornady XTP Magnum bullets into a three-inch group at 45 yards, which is about as far as I feel comfortable shooting while hunting with this gun. It generates 1,125 ft.-lbs. of energy at the muzzle, maintaining 937 ft.-lbs. out to 50 yards, making it a perfectly viable choice for deer, black bear and hogs.

There are heavier bullets available, like the Grizzly 335-grain hard-cast flat nose at 1,175 fps, which will hit like the hammer of the gods, or the Buffalo Bore 325-grain cast load at 1,325 fps, for a bone-smashing 1,267 ft.-lbs. of energy. Both of these loads are far too hot for a standard Colt SAA, but work perfectly in the Blackhawk and Redhawk handguns, and engender a whole ton of confidence while fishing in bear country, or pursuing bears on purpose. The .45 Colt also makes a perfectly viable self-defense handgun; the case is fully capable of firing the 185 and 230-grain bullets designed for use in the .45 ACP, which are equally effective and affordable. If you’re into speed, look to the 150-grain Cutting Edge Handgun Raptor—a monometal hollowpoint that is designed to have the nose section break into blades that cause all sorts of impact trauma. These light-for-caliber wonders can be driven to over 1,600 fps! As you can clearly, see, the .45 Colt is fully capable of handling a wide variety of shooting situations, from self-defense to plinking to hunting.

The concept of improving the performance of a .45 Colt is certainly not a new one; Dick Casull began building a better mouse trap in 1958 and ended up developing the .454 Casull. Extending the .45 Colt case by 0.098”, the .454 Casull delivers a definite improvement over the .45 Colt, yet the Casull chamber can effectively fire the .45 Colt ammunition, making a great choice for practice or plinking.

Considering that the .45 Colt has been with us for 143 years, it remains a completely relevant, powerful, and well-balanced handgun cartridge, that is equally at home at a Cowboy Action Shoot as it is in the hunting fields. A performance record like that is hard to refute, and I think it’ll be with us for another century and more.

The 45 LONG Colt was so designated as to not be confused with the shorter 45 SCHOFIELD round.
I have the Blackhawk 45 LC too, I put pachmiers on mine, much more comfortable to shoot.
I cast a LEE RFP that weighs 260gr with wheel weights. Unique 9.6 gr. YES, it could be hotter, but WHY. I read about a guy shot a boar running away with the same load, in the rear hip, out the chest. DRT. A dead deer, or any other critter, can tell any difference. Accuracy is the name of the game.  A missed target puts NO meat on the table. The only hot loads I make are 200 gr HPS for the house. CHARLIE.  ;D ;D

saw a 1000 lb buffalo shot with a 255 ahead of 9.3 grains of herco. Bullet went in the front sholder  with a front on raking shot. Broke that shoulder and came to rest under the skin right ahead of the hind quarter. Shot one myself with a 44 mag using a 44 spec level load. I didn't intend on killing a buffalo that day because we were pig hunting. Opportunity presented itself and I had my 4 5/8s 44 super Blackhawk loaded with a 240 rcbs swcgc with 8 grains of unique. Shot the 1100 lb buffalo broadside and broke both shoulder and the buffalo stood there spraying blood like it had a garden hose in its mouth for about 3 seconds and dropped dead. Fastest kill I ever seen on a buffalo. Anyone that's shot them even with rifles will tell you they suck up lead like a fly biting them. Shows you a good cast bullet at 900 fps will do a lot of killing. Ive seen many pigs killed with loads just like that. Ive killed a bunch of deer and a few bears with loads like that too. Now would I have headed out to shoot a buffalo with that gun and load. NOPE! Ive got 475s and 500s that will do it better so why try to shoot something with the smallest gun in the safe! That line of thought never made sense to me.

Fifteen years ago when I communicated with Lee Jurras and John Linebaugh several times a year, I was informed a .45 Colt can do everything a .454 Casull can do when hot loaded and back then, for less money, but that has changed with the non-custom guns now available.
You did not call it a .45 Long Colt o r you would be looked at with disdain, or worse by those gents, and their contemporaries back then.
You were informed that term came about because of some ignorant wannbe gun writer .

Back in the ninties to early oughts a lot of revolvers were being converted into five shooters to take very hot loads in .45 .Of course the .475 and .500 Linebaugh got more press, and then the long versions, which of course S&W copied to sell their own  non cartridge interchangeable revolvers.When I went to the Linebaugh seminar I shot the five shooters and the .475 Long is the one that has tremendous recoil, while the five shot .45 gets your attention but are not near what the long .475 version is.

if by 475 long your referring to the 475 maximum they yup there recoil is in another world. Ive owned 475 and 500 linebaughs for near 30 years and they have substantial recoil. My buddy has 8 Linebaugh guns and is one of Johns best friends. Two of his guns are a 475 max and a 500 max. With full  power loads comparing them to the standard 475 and 500 is like comparing full power 475 loads to a 44 mag with factory ammo. There in a different world!!! Think of shooting 500 smith full power ammo in a gun that weights a lb or more less then the smith. It will make the inexperienced and the ones asleep at the controls BLEED!! My first time with his 500 max had the hammer putting a nice hole in my scalp on top of my head and im far from inexpernced with them. The 475 isn't quiet as bad but its still in a different century then the standard one and the muzzle blast is even more intense then the 500 max and will rattle the brain of the best handgun shooters. I love the big guns but have no desire what so ever to own a Linebaugh maximum.

Buy the way the 500 smith isn't a copy of the 500 max. The max shoots 512 bullets and the smith shoots 501 and the smith case is even larger. Far as I know smith doesn't make a .475 there other gun is the 460 which is a hot rodded 454 with again a larger case and uses a larger rifle primer vs the 454s small rifle primer.

I am full aware of that but many writers have said that S&W just took the ideas and made if different as they simply would not give John credit for what he created.
The so called 480 is different from the Linebaugh .475 simply so they could not interchange, ditto for the .500 .
The so called 460 is different from the Casull so they would not be just making a gun for some one else's cartridge.
When I used to talk to John , he had little good to say about dealing with the big companies.
