The .450 Bushmaster is a rifle cartridge developed by Tim LeGdre of LeMag Firearms and licensed by Bushmaster Firearms International. The Bushmaster .450 is designed for use in standard M16s and AR-15s using modified magazines and upper receivers.
Bush Master 450
The .450 Bushmaster is based on the Thumper concept popularized by gun writer Jeff Cooper. Cooper was not satisfied with the AR-15 5.56×45mm (.223 Remington) NATO subcaliber and saw the need for a large-caliber cartridge (cal. 44 or larger) in a semi-automatic rifle to provide a single shot. kills big game at 250 yards. Inspired by this, LeGdre developed its .45 Professional cartridge,

Ammunition manufacturer Hornady made a .45 Professional cartridge for the project, but Hornady wanted to shorten the case and overall length to accommodate the .452-inch 250-grain SST flex tip bullet. Bushmaster and LeGdre approved the change from the 1.772-inch (45 mm) and 2.362-inch (60 mm) OAL cases to the now standard 1.700-inch (43.18 mm) and 2.260-inch (57.40 mm) OAL cases. This allowed it to run on the more abundant and popular AR-15 platform over the AR-10 platform. A name change to ".450 Bushmaster" was also approved.
The .450 Bushmaster uses .452-inch bullets because the lower impact velocities and energies would not adequately expand the heavier .458-inch bullets.
The cartridge is chambered in bolt-action rifles from Ruger, Savage, Mossberg and Remington, Ruger's single-shot rifle no. 1, AR-15 rifles, as well as the Franklin Armory AR-15 pistol.
Ballistically, the .450 Bushmaster has a fairly flat trajectory out to 200 yards; if the firearm is zeroed at 150 yards, the user can expect an increase of 1.8 inches at 100 yards, a zero at 150 yards, and a drop of 4.9 inches at 200 yards.

The cartridge fits one magazine in a standard AR-15 magazine with one follower. The 10-wheel magazine body of the AR-15 gives four wheels
Hornady, Remington, and Federal magazines now make rifle ammunition, and Starline makes hollow brass for handloading. This famous saying, often attributed to King Solomon, pretty well sums up the development of cartouches over the past 40 years or so: “What has been will be done again, there is nothing new under the sun. "
Some modern cartridges have improved upon their predecessors, but hunters and sports shooters are rightfully skeptical that The Latest Thing™ will ever surpass what came before.
Take the .450 Bushmaster for example. Released in 2007 and designed for use in semi-automatic rifles on the AR platform, the .450 promised a massive ballistic advantage over the .223 Remington with the ability to take out big game at 250 yards.
Thumper 450 Bushmaster
It gained instant popularity and is still widely chambered. However, there is another .45 cartridge that offers similar ballistics and has been around for much, much longer.
The .45-70 caliber was first adopted by the US Army in 1873 with the Springfield "Trapdoor" rifle. It served for 19 years before being replaced by the .30-40 Krag, and has seen a resurgence among American rifle manufacturers in recent decades.
Why would a hunter opt for the younger Bushmaster .450 when the .45-70 has been doing the yeoman's work for nearly 150 years? Read on to find out.
While the early versions of the .45-70 would be woefully underpowered by today's standards, the smokeless powder gave the government a real run for its money. Most .45-70 offerings can push a 300-grain bullet at about 1,850 feet per second (fps) and produce 2,280 foot-pounds (ft.-lb) of muzzle energy. Some of them go as fast as 200-300 fps, but all of Federal's offerings hit 1,850 fps.

The .450 Bushmaster can also be loaded with a 300-grain bullet, and with that projectile it essentially mimics its predecessor (1,900 fps, 2,405 ft-lb). However, the Bushmaster can also commonly be found loaded with bullets in the 250-grain range, which increases both velocity and energy. This 260-grain Fusion, for example, flies 2,200 fps at the muzzle and produces 2,794 ft.-lbs. energy
This increased velocity causes the bullet to shoot flatter, helping the cartridge deliver on its 250-yard promise. While the aforementioned 300-grain .45-70 drops about 42 inches at 300 yards, the 260-grain .450 Bushmaster only drops 37 inches. At that distance, it still hovers around 1,155 fps and delivers 770 ft.-lbs. energy
It is possible to find .45-70 options that more closely mimic the lighter .450 Bushmaster cartridges. Some cartridges are loaded with 250- or 225-grain bullets and can deliver velocities up to 2,700 fps and 3,700 ft.-lb. energy But the .450 is much easier to find loaded with these lighter bullets, which provides a significant advantage if you need to hit an animal beyond 150 yards.
Of course, if you want a bullet heavier than 300 grains, the .45-70 is the best choice. While some companies make subsonic .450 Bushmasters with 395-grain bullets, the .45-70 can be had in a wide variety of loads with bullets from 325 to 400 grains. These projectiles have even more limited range, but provide exceptional short-range power against large animals.

The bottom line? pick your poison The .450 Bushmaster generally uses lighter bullets that reach a little further, while the .45-70 shines in big shot and short shot scenarios. But when comparing apples to apples, the .450 offers a slight velocity advantage, so this round goes to the Young Gun.
Neither the .45-70 nor the .450 Bushmaster have a reputation for being smooth shooters. Both are high-caliber cartridges that fire heavy bullets north of 2,000 fps, and all that energy in the barrel is reflected in the shooter's arm.
However, the .450 Bushmaster is easier to shoot for several reasons. First, it tends to produce less recoil than the .45-70. Recoil can vary greatly from load to load, but the .45-70 typically produces more than 25 ft.-lbs. of recoil, while the .450 Bushmaster lives up to 20 ft.-lb. range Shooting a bolt-action .450 Bushmaster with a muzzle brake is like shooting a bolt-action .308 Win. On the other hand, .45-70 will usually feel more like a .300 win. Mag.
The .450 Bushmaster also has the advantage of being commonly chambered in AR model rifles. These rifles have a built-in damping system that absorbs recoil even in a light rifle. This is not a characteristic of the cartridge per se, but since the .450 was designed specifically for use in these types of rifles, it is worth noting.

We define “shootability” as recoil plus ammo cost and availability, and the .450 Bushmaster wins in that second category as well (but just barely).
The government had a 134-year head start on the Bushmaster, and its continued popularity means there are more options for the .45-70 than its counterpart. Midway USA, for example, offers 44 options in the .45-70, while only 17 in the .450 Bushmaster.
In terms of ammo cost, the .450 Bushmaster usually beats the .45-70. You'll pay a few bucks less for a box of 20,450, and you can find Bushmaster cartridges for as little as $1.40 a round. Cheaper .45-70s, on the other hand, run north of $2 a round, according to Midway USA.
Frank C. Barnes states in "Cartridges of the World" that both the .45-70 and .450 are suitable for any American big game, from deer to grizzly. Neither is ideal for insects due to their limited range and large diameter bullet, but both are excellent deer cartridges that can target elk, moose, and bears at more or less 200 yards.

These cartridges are also tight for rifle versatility. If you want a semi-auto rifle, the .450 is the way to go. Several companies offer AR pattern rifles in the Bushmaster, and several other companies offer bolt action and single shot rifles.
If you're looking for a lever action pistol, the .45-70 is an obvious choice. Many companies have put a lever gun in the old government, and you can also find a variety of single shot options. A few boutique gun manufacturers have AR type rifles in .45-70, but they are few and far between. The used market will also favor the .45-70 due to its extensive history in the US.
These rounds, which cover the same range of animals and have a similar selection of firearms, end this round in a tie.
The .45-70 and .450 Bushmaster are more similar ballistically than proponents of The Latest Thing™ would probably like to admit. For bullets of the same weight, the speed, energy and trajectory are practically identical.

Still, the lighter .450 bullets give it a slight advantage in most hunting situations. The ability to capture big game at close range and out to 200 yards means the newer cartridge offers some improvements over
