450 Bushmaster vs 458 SOCOM vs 50 Beowulf

45-70 !!!!!!!!!!!!!!!!!!!

450 bushmaster. Only because ammo would be easier to get.

It would be cool if they can get 475 h&h into a AR platform

Straight walled cartridges easier for reload and brass last longer. So that leaves out the 458 for me

I like the 50 Beo in 12.5” barrel for my uses, excellent brush rifle. Rolled a big hog shooting through a mesquite bush.. thats a thumper!

50 Beowulf is tempting. There are AR uppers for it at a decent price. I really don't have any big bore firearms so I feel having one will round out my collection.

Very informative thank you. You got a subscriber from me.

I think 450 bushmaster is the best way to go. It honestly outperforms the other 2 and more ammo availability and rifles to choose from.

The FTX on beo is crap round, the jacket peels away and fragments, you do NOT get hollow point expansion. You get a slug and copper bits spread thru target not optimal.

I have a few types BEO rounds. Some that smoke what those others can do. It’s fun to load a mag w a couple of each to feel the difference. All good enjoy the video!

The poor stopping power of the newer 5.56 round is because NATO wanted more bullet stability with a 1/8 twist after the Vietnam War. The reason is Eugene Stoner designed his M16 with a slow 1/20 twist which that made for a very unstable round that left insane wound channels that NATO decided was inhumane to use in battle.

Just finished an AR-15 build in .458 SOCOM and working on load development. So far, been very happy. Thinking about building another subsonic suppressed in this caliber. Open to comments or suggestions.

So at the end of FJB/LGB .
450 is Whaaaats Uuuup!

Great description! Thanks for the help!

Awesome video! Thank you for putting this together.

All the ammo is stupid high cost.

I think you set up 450 Bushmaster to look best in the comparison by using the lighter bullet. If you put a 300 0r 350gr in the 450, you would be a lot closer to the 458. Inversely, put a 250 or 200gr in the 458 and you will be a lot closer to the 450. The 458 also has a much larger selection of bullet styles and weights. The 458 SOCOM also beats out both other cartridges' in the Sub Sonic realm with reliability and wide range of bullet weights that reliably function.

Sorry had to comment. When people want a Beowulf, they go the cheap route. 99% of the time. I spent the $$$$$$$$ and bought the real deal Alexander Arms. She roars. Never jams { I use their magazines and their bullets } Problem going cheap is jamming and FTF. I hear it all the time . Regular A.R.'s weren't designed for the 50 Beowulf, hence {problems} But everyone is always trying to get by or do it cheaper. And that doesn't always work out . I saw a Bigfoot …!!! It was one of the most intense, scary moments in my entire life. It changed me. I knew it could of killed me . I knew who the king of the mountain was and is. Since owning and carrying my Alexander Arms Beowulf and my Glock 20 . I'm not the screaming crybaby anymore. When you have a monster eyeballing you like you're dinner. You'll learn cheap isn't always the way to go. Peace.

The 450 bushmaster is the best all-around bullet

I personally own a 450 Bushmaster. The main reason I chose it over the others is the loaded ammunition is cheaper and reloading for the Bushmaster is very easy and also cheaper components. In my testing the 450 has been very accurate out to around 200 yards and has just about the same stopping power as the 50 Beowolf. The only differences is really in subsonic loads where the 458 and the 50 can be loaded with very heavy bullets that are superior to the 450. So far I have had difficulties getting any 450 subsonic loaded to cycle reliably in a AR platform. Thanks for a good review.

50 beowulf fan here, its got the most raw power up front with the lowest price tag for commercial ammo… or it did for a while. It does really well with 16" bbls and under, while most 450 BM figures are from a 20" bbl. 458 is, in some ways, the very best between the 3, but commercially, it's a huge PITA.

50 is just terminally NUTS at short range. But the 45s slow down a little slower.

Note: 50 Beo also has a nigh identical copy cat chambering that several manufacturers produce.

I didn’t detect you saying one round was better than any these round you reviewed and thank you for including the 45-70. But having given the statistics presented here I’ve got to say there’s a good reason the 450 Bushmaster is more popular.

How many of each fit n standard 5.56 mag? And which is ar15 and ar10? I want which ever one I can build in the lightest form. Thank you

What’s the best barrel length for hunting for the 450 16 or 18 in?

If you're worried about 5.56 being underpowered for a deer, just use a 9mm glock. According to one expert a single 9mm bullet can blow a man's lungs out of his chest. Now that is stopping power.

The 458 socom. But because of ammo available. 450bm!

Like .300 blackout, .458 socom is 110% for reloaders

.AA 50 wolf is my go to in field next up 45/70 Henry's. Accurate and big boom from the .50 is what I like I have paws of a grizzly so bigger better for me.

Do you know if I can use 458 socom magazines loaded with 450 bushmaster cartridges in my Bushmaster rifle?

Bought a .50 Beowulf M-4 upper from Alexander Arms just because back in 2010. It's fun to shoot and can be very accurate. Was using Rainier 275, 300, 335gr bullets in both FMJ and HP's Sometimes groups were a single cloverleaf at a 100 yrds. Sometimes not! Rainier is out of business, didn't survive the Covid lock-downs. I found I had to weigh the Rainier bullets cause they could vary as much as 5 grains or more between bullets. The 275's were short and didn't provide much of a bullet for the case to grip. The 300 and 335 shoot the best. Only thing mine has killed is paper and steel targets and some desert jacks. It just puts really BIG holes in them! The .50 Beowulf is really a Big Pistol round. It uses Large Pistol primers. The plated bullets are for pistols and don't hold up well if pushed too fast. Rainier were good for plinking. I have some Berry's 350's, Speer GD 300's, some of the Hornady FTX Flex Tip 300 Grain Bullets. But most of my shooting was/is with the Rainier bullets glad I stocked upon them before they went bye bye.

I built a 50 Beowulf and love it! The cost of ammo is prohibitive and factory ammo is Alexander Arms only! I eventually built a 350 Legend and shoot that way more due to the inexpensive ammunition and availability of factory fodder!!!!!

SO WELL DONE, I'M A SUBSCRIBER.

Thank you very much for a very detailed video! I subscribed and rang the bell, I follow a ton of apples to apples gun guys in comparison your video here on these three rounds is definitely the best! When someone asks on Google your video should pop up and they need not look any further.

Absolutely beautiful details to your description!!@! Wow! Brother..Subbed!!! We The People like your Content!!450 bushmaster

450 bushnasty all day long.

They're cute. Not enough power though.

I have the .450 Bushmaster and the .50 Beowulf in AR Platforms. The .450 Bushmaster is superbly accurate and other than handloads the Hornady Black 250 Grain FTX is all that I can find! In .50 Beowulf all I have been able to find is the Underwood 350 Grain Hornady XTP and not nearly as accurate as the .450 B', but it is Oh So Powerful!!! I ended up with 2 Lancer 20 round magazines (which hold a total of 8 + 1 cartridges) and Tromix followers which is reliable (and holds the bolt carrier group back on an empty magazine) in the .50 so it gets the nod when I go out (with even more potent handloads!) Even with magazine modifications I cannot get reliable full capacity performance with the .450 B' which is a shame! By the way I have held Jeff's M1 Carbine chambered in .450 Thumper which was the very beginning of all of this (unless you consider the bolt action .376 Steyr and it's predecessor the Remington Model 600 .350 Magnum Scout Rifle(s) to be in the mix.) What is my hunting get up; that's easy, a very old Ruger M77 in 7mm Remington Magnum with a Nikon Scope and my lucky Thunderwear!

Ordered AA new BEO on October 7, 2021. Just got last Friday. New stuff. Letcha know. 22,000ft ballon poppers, swear it. BEO and 450, no real comparison. 450 💖 love it. Shoots like butter. BEO blows fire. 357 vs 500 Mag. Same type difference. Still wait for real AA Grendel Ammo. Rare stuff.

Wish they would get the 458 socom sammi certified,than more guns and amm could be manufactured for it!

In my opinion the 450 Bushmaster the best of the three. Look at the three the 450 Bushmaster has more load ability as far as powder capacity. I load mine at the level are the 460 Smith & Wesson. The 450 has the same case capacity as the 460. So when shooting an encore or a bolt gun you can load it at higher pressures.

450 Bushmaster seems to be the best. Ty for this.
