450 Bushmaster AR-15: An Overview

If you're a gun enthusiast, then you've probably heard of the 450 Bushmaster AR-15. It's become increasingly popular in recent years, and for good reason. This rifle is a powerful and versatile firearm that offers many benefits to its users.

History of the 450 Bushmaster

The history of the 450 Bushmaster goes back to the early 2000s when Tim LeGendre wanted to create a cartridge that was more powerful than .223 but still able to fit in an AR-style magazine. After much experimentation, he came up with what we now know as the .450 Bushmaster.

This high-powered round gained popularity among hunters looking for something with more stopping power than traditional rounds like .308 or .30-06.

Comparisons with Other Cartridges

When it comes down to comparing cartridges that can be used by an AR platform, some common contenders are:

  • The .223 Remington
  • The 6.5 Grendel
  • The .458 SOCOM
  • The .50 Beowulf

Compared against these other options available in today's market, it’s clear why so many people have chosen this caliber over others – especially if you’re going after larger game at closer ranges or want some extra punch through barriers like brush.

In terms of size alone, though the case length on paper may not seem all too different from other potent cartridges out there such as those mentioned before–the overall dimensions on this ammunition make quite clear how much bigger each individual bullet actually is when compared side-by-side with similar offerings from previous designs.

Benefits & Advantages

There are several reasons why someone might choose to use a 450 bushmaster ar15 instead of another caliber – including better accuracy due largely thanks largely because recoil while firing off multiple shots quickly tends towards being less pronounced overall (which can be especially important in hunting scenarios where you may need to take several shots in quick succession).

Another benefit is the amount of stopping power it offers. If you're hunting larger game and need a round that can take down an animal quickly, then this rifle could be just what you're looking for. The 450 Bushmaster has a maximum pressure level set at 38,500 psi which results in lower recoil than .308.


  • The ammo used for this cartridge is readily available.
  • It's more affordable than many other big bore alternatives.
  • It’s easy to convert your existing AR15 into one that packs some serious punch with little more than swapping out upper receiver or barrel assembly.

Tips on Using the 450 Bushmaster

If you've decided to use a 450 bushmaster ar15 for your firearm needs, here are some tips:

  1. Use quality ammunition: Since there's such high demand for this caliber, there are plenty of ammo manufacturers producing rounds with varying degrees of quality control standards – so it's important to research before buying new rounds in bulk.

  2. Use good optics – like any rifle platform—being able to reliably hit targets comes down largely on the shooter themselves—but pairing with proper glass (not only zeroing but also having suitable magnification depending upon anticipated range) greatly aids marksmanship ability as well as confidence when lining up those critical shots.

  3. Keep it clean: Clean your gun regularly and make sure everything is properly lubricated and tightened up before firing off new rounds after long periods between uses; failure rates tend towards being higher due mostly because operator error/malfunction (versus inherent mechanical issues).


The 450 Bushmaster AR-15 has become increasingly popular among hunters who require accuracy, reliability along great penetration through brush/other obstacles commonly encountered while seeking prey animals like deer or wild boar etcetera.. As always though—as an informed and responsible gun owner, ensuring proper safety protocols are followed—along with knowing the limitations of your equipment—are fundamental principles to keep in mind when using any firearm and especially when dealing with high-powered rounds like this one.


What is a 450 Bushmaster AR-15?

The 450 Bushmaster AR-15 is an upgraded version of the popular AR-15 rifle. It is chambered to fire .450 caliber bullets, which makes it more powerful than the standard .223/5.56mm round used by regular AR-15s.

The 450 Bushmaster was developed by Tim LeGendre of LeMag Firearms LLC, and later licensed to Hornady Manufacturing Company for mass production. This cartridge was initially designed as a big bore hunting round that could bring down deer or other large game with one shot.

The advantage of using the .450 caliber bullets in an AR platform rifle lies in its ability to retain energy over long ranges while producing high terminal performance on impact.

In terms of popularity, the 450 Bushmaster has gained significant attention among hunters and shooting enthusiasts due to its versatility and stopping power – making it suitable for hunting big game animals such as elk or bear.

What are some benefits when using a 450 bushmaster ar-15?

There are several advantages when using a 450 bush-master ar-15:

  1. Power: The most prominent benefit is its superior stopping power compared to standard calibers like .223/5.56mm rounds. This means that you can take down larger animals with less effort while also being able to shoot through thicker brush without losing velocity or accuracy.

  2. Accuracy: The cartridge design provides excellent accuracy at long distances due mainly from its weight distribution, bullet aerodynamics along with muzzle velocity exceeding speeds up-to2000 feet per second (fps).

  3. Versatile: Another great feature why people opt for this rifle type model because it's versatile in usage given users can use them both as hunting rifles and home defense firearms alike.

  4. Easy Handling & Maintenance: Lastly, maintenance on these firearms tends not be too complicated if compared against other powerful rifles like .50 BMG, ammo comes with a relatively affordable price and is readily available in most firearm stores.

How far can you effectively shoot using a 450 bushmaster ar-15?

The effective range of the 450 Bushmaster AR-15 rifle depends on several factors such as bullet weight, wind speed/direction, altitude, and shooter skill level. However, it has been recorded that firing at distances up to 250 yards with good accuracy is achievable.

It's important to note that the bullet trajectory changes significantly beyond this distance due to reduced velocity and increased air resistance. Despite these challenges one can still fire consistently on-targets up-to distances between ranges of around 300 yards provided adjustments are made for factors listed above beforehand.

When it comes to long-range shooting distance accuracy becomes more precarious due to bullet dropoff; hence aiming technique adjustment must be accounted for accurately when engaging targets past ranges over approximately two hundred fifty yards.

What type of hunting game is best suited for a 450 bushmaster ar-15?

Hunting game types suitable for use with a 450 Bushmaster AR-15 would primarily depend upon three main factors: size & weight of animal(s), terrain & environmental conditions (e.g., wooded or open areas ),and hunting regulations within your state/country.

In terms of mid-sized animals like deer or feral hogs – which have thick hides along with tough shoulder bones – the .45 caliber rounds provide enough energy transfer during impact ensuring quick lethal takes without causing unnecessary suffering before death occurs; making them ideal targets respectively!

Additionally bears make good usage candidates as well given their dense yet sensitive body structures but caution must always be taken while in bear country because viewing them from afar through spotting scopes/binoculars suggested before dangerous close encounters occur!

Ultimately however regardless what target species hunters choose using cartridges ranging from Hornady’s FTX or Barnes’ Tipped TSX bullets among others provides the ideal combination of accuracy, power and performance to hunt most big-game animals successfully.

Can you modify a standard ar-15 rifle to use 450 bushmaster ammunition?

While it is possible to convert a standard AR-15 rifle into one that can fire .450 Bushmaster ammo, the process requires more than just installing a new upper receiver or barrel.

First and foremost, you need an upper receiver assembly chambered in .450 BM. The only parts reusable from your old upper are the charging handle and bolt carrier group. Additionally, if your AR doesn't have a full-length buffer tube (A2 or A5), then an extension kit will be required too.

Next step would require purchasing verified magazines sold by Hornady for this cartridge type as well as swapping out lower receiver parts such as hammer springs with ones that fit this caliber too.

Finally headspacing should be checked by qualified gunsmiths before firing any time after modifications are complete due variations between manufacturers specifications which could lead potentially harming oneself if done improperly!

In short – while it's technically possible to make these conversions at home through DIY methods; we highly recommend seeking advice & assistance from professional experienced gunsmiths who've previously made similar conversions themselves!
