450 BUSHMASTER VELOCITY ~ 16" VS 18" BARREL 

Kudos to Chase for knowing how much to talk when Buffalo be talkin ;)

Thanks Buffalo. Bought the 16” from BCA just need to assemble the lower now. Thanks again

Thanks gents....enjoyed the afterglow paint shooting as much as anything.

Side charger looks interesting ! Thanks Buffalo ! ✝️

Good video men. Helped me out a lot, thanks!

Thank you guys!!!

Congrats on 70k subs, you should have so many more with this content, looked like a whole lotta fun👍🇦🇺

Thanks Buffalo for this video. You helped me make up my mind. It’s going to be Bear Creek with 18” barrel.

I've got a couple BCA uppers. The 18" .450 and 20" AR-10 upper in .243 Winchester. Love them both. I've yet to have any issues with either. I have close to 400 rounds through my .243, and about 300 out of my .450. Very accurate and reliable to this point, be it on the range or in the field. For some high value goodness check them out.

I wanted the BCA side charging .458 Socom or .50 Cal. But that .450 Bushmaster looks like its a hard hitting, beast too! I like your simple and easy testing methods! That's all, most of us need.

Less difference than I thought it would be. Good info thanks guys!

Checking velocities was a necessity, but I knew it wouldn’t be long before y’all were blowin stuff up😁 Seriously thinking about skipping the 300BO or 7.62x39 and just going straight from 5.56 to .450 Bush and the side charger looks really sweet!!!

Some great results for a big heavy bullet. I pick up a 16 inch heavy barrel in 300blk and its a take driver

Thank you!

Thanks for the comparison ...

Thanks for the video.

That .450 Bushy packs a punch on both ends. :D

Thanks for sharing and take care. 👍

My 18” is a fantastic shooter. Did have a low gas issue to start though. Fixed and fantastic now

Great information. Thank you

That is what ya some serious fire power. Nice one Buffalo....

Great channel..if iam researching something for purchase i definitely look here

Great video

Great videos. Watched parts 1-3 from when you first took that upper out of the box. Been collecting parts to build an AR 450 and debating on what upper/barrel to get. Going to see if that one is still available and if not see what is closest to it on BCA's site.

This is going to be real good, well that was interesting 100 feet a second that’s actually a lot, I wander want a 20 inch barrel would do

I wouldn't have thought it wouldn't have been that much either. Nice vid👍

That was awesome thank you

Two nice guns there boys. Buffalo is always on the edge. 16 and 18 inch barrels you wouldnt think would make over 100 feet difference in speed. Live n learn boys. Thanks guys

Fun video and great chrono data. I'll take any data I can get. It may not match my results , but it will always calculate into real world use.

I'll have to try that the next time I need to repaint my targets and backstop

Its an additional 200+ foot pounds of energy from that 100 fps boost.

Well done Buffalo

Good velocity on a big round!

Congrats on the new rifle for deer season Chase! Buffalo, I just noticed you have over 70k subs and wanted to congratulate you on that also!! I kinda want a side charging 450 BM for deer & hog huntin...🤔😜Thanks brother, Stay safe & God bless👍🙏🇺🇸✌

100 fps. in just the last two inches of barrel, didn't expect that much difference. That 100 fps. with that big bullet amounts to a pretty good amount of thump down range. I guess those heavy rounds need all the push they can get. Good info, thanks for the video.

Remarkably consistent ammo, round to round. A little more difference between the lengths than I was expecting. Be interesting to repeat the test in a years time to see if the difference holds over time.

Close enough for me Buffalo!

Can the side charger be used on left side? I love my BCA upper. Thinking about another.

Great video, should have toss in a accuracy test too at different distances , just to see if 2” would make any difference

I love my Bear Creek Arsenal! It appears their firearms doubled in price since last year too. Good thing I got mine for less than $900!

I found with my .308 AR-10s with barrels from 16 to 24 inches that there was about 100 fps difference per 4 inches of length.

Thought for sure it would have been less than 50 fps... Surprising!

I’ve got the 16” side charging upper… seems to have trouble cycling… what buffer setups are you using?????

As a general rule, in my understanding, with rifles there is approximately 50 fps difference per barrel inch.

Good shooting fun amongst friends....Good stuff....

The .450 is a great cartridge within the limits of the AR platform for short to medium range hunting for deer/bear/hogs etc. I would rate it far above the .350 Legend, which is nothing more than a slightly juiced up 113 year old .351 WSL. (the .351 will certainly kill the same game, the bullets won't bounce off!) Within that range of game and typical distance, the difference of 100 fps +/- will make no difference any hog/deer/bear could report. Anyone trying to make much of it would be splitting some very fine hairs. The barrel length and overall handling of the gun would be the deciding factors for me. Choose which one meets your hunting needs best. That said, all variables aside, the optimum barrel length for the .450 is obviously greater than 18". Don't imagine that a 24" barrel will give 300 fps more than a 18" barrel...but it WILL ruin the rifle for carrying in heavy brush. And that IS what the rifle excels at. When I bought "first" centerfire rifles for my sons, I went with the Ruger Model 77 International with 18.5" barrel. Beautiful rifles and very easy handling and accurate. One of them is a .243, the other a .250 Savage (and NO, I do not favor the son I gave the better .250 Savage rifle to!) It just happened the gun shop had two in stock, one in each caliber. The 18.5" barrels do not produce anywhere near the "factory" velocity ballistics for those two cartridges, but for nearly 40 years now, both those rifles have killed a lot of deer/hogs and none of the deer and hogs noticed the difference. And yes, both those cartridges with good quality 100 gr. bullets are deer killing machines! Just a shout out to BCA...they make great products. I have three of their uppers and they all perform very well at the range!

How does the Lancer 20rd mag do with a tromix lead handle 450 bushmaster

Can you all do an accuracy test on both barrels. Thanks

The Midway Stoner brand is I believe made by BCA, my Midway USA 6.5 Grendel upper looks just like the BCA.

I wonder what kind of minute of hog accuracy there is between the 2 rifles. The 16 inch looks like the length I like best.

My question is why were you using only 3 round mags? Is it a weight issue?

Hey Chase...BLUE Loctite that side charging handle in before long if you haven’t yet done it👍😊👍😊 BCA has always been 100% if set up properly!

450 Bushmaster hmmmm. A friend of mine just got a Savage Haymaker WOW I did not think something so large would be so darn accurate. I think I would want the 18in barrel.

I wish that a 20 inch barrel of the 450 Bushmaster was included in this video.

Hey buffalo did you sneak in a paul harrell reference in there lol?

I was asked why I wanted a 20” over a 16 “ when I got into 450s , to get the most out of it was my answer. Then I got a 16” bolt for the hell of it and wouldn’t part with either ! 😎

What magazine are you using for this ? I'm having feed issues with mine

"He's DEAD, Jim!" (Star Trek humor.) Thank's for this useful test!......................elsullo

If you and your pal can get together in winter with no wind and fresh snow on ground, shoot a few rounds for one these rifles and "read" the snow for amount of unburned propellant. Repeat on fresh snow for other rifle. The 18" may not be as efficient. This is highly dependent upon the powder and chamber pressure.

Were they both 1/24 twist?

What was the difference between the two with the Noise level....

The CVA scout has a 25 inch barrel. Wonder what those velocities would be?

I have the 18 BCA .450 also..... well made but they are hefty

Those are some thumpers

Been wondering what the barrel differences would have on velocity. Amazing what an extra 2in can do;)

Those last few shots were downright nasty ...in a good way. Man, those targets EXPLODED all over the range! Did you hand him a grass rake for clean up after that? :)

Sweet shooting I've been considering getting a CMMG 6.5 grendel, do you have any time with that particular caliber ?

That must be a big round if only 3 fit in the mag, unless those are 3 round mags for hunting purposes

Those rounds do have quite bit of thump to them

Did you tell your buddy to try super hard to look like a bad ass, or is he doing that on his own?

4:18 is this a ice can you splattering ???

Just for giggles swap muzzle devices and see if there is a difference.

It appears from this test that the ladies MIGHT be correct, length matters. 😉

I'd like to have a 14.5 inch barrel pinned and weld to make 16 inch. Would be great for home defense

I don’t know the formula so how does that compute in energy?

Sorry, I was just wiping some drool off of my tablet from those rifles! .450 never really gets any recognition, which is beyond me. It’s a seriously B.A caliber, so everybody else’s loss!! Great video brother 👍🏽

Your Buddy what is his ar name

👍👍

Yea, sadly 😳

I was out yesterday chronographing my 10.5" barrel, same Hornady ammo as you, and was hitting 2000 fps consistently.

My .450 has a 20 inch and have wandered what the extra couple inches would do. It’s freaking deviating on a whitetail deer 😳

And i have a 25 inch cva scout

Use the Hornady black and get so e more fps

Chase needs to move his bipod up to the very front of the free float tube for best stability..... anything less is a waste.

Sorry, had to put you on "Pause" while I got my after dinner coffee. You may continue now........😂👍🏻👍🏻. 🇺🇸😎

Do you think 450 has to much recoil for a 12 year old kid?

☕🙂👍

The difference isn’t too important when you hit where your aim. I doubt the deer, pig or bear is going to be any deader when shot with either of those rifles.

More important than a small amount of f.p.s.. is the twist in the barrel.... I've seen heavy caliber round exceeding 2400 f.p.s.that was accurate no more than 50 yards..it the twist rate that counts.. not the velocity...heavy lead needs the right twist....45:70 is accurate as can be at 1300 feet per second because of the rife barrel twist.....trust me

Surprised by that difference. Both good hunters for is Southeasterners.

Love BCA, that possibly would bother a hunter. But the 100 yards and under plinker I think it would not matter. But that's just me :-))_

They are thumpers

100 fps between the 2 barrels sounds a lot, but it's actually only 5.5 ft/lbs of muzzle energy difference

I’m a little bit of a gun nut but AR platforms annoy me. The originals, pure, simple, clean. The original original, beautiful and powerful. Colt, Brownell copy of originals, and maybe Beowulf, otherwise same same. Sorry kids.

Get rid of the stupid flash hider and lose like 2" of the barrel length.. that's what I did and just put a thread protector on.

I just took one for the team and watched a joe Biden presidential ad on your video. I hope that proves I appreciate your content. But now my eyes hurt, and I feel kinda dirty.

great test, great info, thanks guys

Great video
