Ar 15 Rifle for beginners: Understanding bullet weight | length with 5.56 Nato and .223 Rem.

In this video, I'll discuss and explain the differences between typical Ar 15 Rifle bullets in 5.56 Nato and .223 Rem., including their weight and length and how it relates to Ar 15 rifle barrel twist.

[@Magswap]

I love the video topics you come up with! For some reason I love learning about these intricate concepts with firearms.

[@PracticalAccuracy]

Thank you. More to come.

[@Joe_Dirt82]

Glad I found this video. Think you're first person I've found that explained the difference in 223 and 556 pressures while most of the others said there's no difference. Thanks for the knowledge.

[@PracticalAccuracy]

You are welcome

I have a CZ 527 varmint in 223. After doing my research before purchasing a bolt action rifle, I found this! CZ rifles chambered in.223 can fire 5.56 ammunition safely?” A: All of our.223s will happily eat 5.56. Since our factory is in Europe, we build everything to CIP spec, which doesn’t differentiate between the two cartridges and just has the higher pressure as its standard. This is the reason I decided on a CZ Varmint, and also another contributing factor was that my CZ 455 in 22 cal. simply amazes me with how accurate it is with any ammo I feed it! Great vid!

[@PracticalAccuracy]

Awesome. Thanks for watching.

[@Ally-ds6lb]

Perfect video for beginners!

Glad you think so!

Can’t believe you only got right under 3k subs

Thank you. More videos to come shortly.

[@lindaturner9806]

I appreciate your channel and how you explain this information so I can understand.

[@eloiseharbeson2483]

Nice presentation. I love the Frontier line. Especially the 55gr OTM 5.56.

[@compasslife6658]

So grateful I found your channel Andy.

[@PracticalAccuracy]

Thanks. I'm glad it's helping you. I'll hopefully have some more educational videos with shooting demonstrations soon.

[@jimjones9239]

The 5.56 has more powder inside the cartridge than 223. More powder equals more velocity (3,200fps vs 2,700fps) and higher chamber pressures. The heavier the bullet, the slower the round but it improves wind drift and has more terminal energy on impact. The only way to notice is to read the letters at the bottom of the cartridge, 5.56 will say 5.56.

[@jammbbs1688]

Great info Andy you're helping me explain stuff to a new ar owner

[@PracticalAccuracy]

You're welcome. Glad it's helping. I'll have more helpful videos soon.

[@RGL01]

Enlightening video!

[@Prariedog]

Awsome video ,thanks for sharing I'm thinking of using 55gr v max hornady 22 cal to reload 223 for a semi auto 1;8 twist Your thought

[@davefranks6562]

I use the same ammunition. Great stuff!

[@PracticalAccuracy]

👍

[@Mythological321]

Many thanks!

[@ViralStacking]

You said 77g is the biggest (heaviest) round you can use in an AR15 magazine? Did I understand that correctly? What about larger (heavier) ammo? Does it need to be single bolt action only? I thought they had some monster 90g subsonic rounds?

[@yjoeyyy]

Have re used wolf ammunition other than a few jamming issues it’s pretty cost-effective ....

[@PracticalAccuracy]

No I haven't. For non match factory ammo I always use federal xm193. thanks for watching.

[@bighx6099]

You did the overall length of just the bullet themselves. But how much length on each bullet actually makes contact with the lands and grooves within the barrel? Do some of the heavier bullets have a longer nose that doesn't touch the lands and grooves? Talk text sorry

[@PracticalAccuracy]

You are correct that the overall length of the bullet may not accurately reflect the contact points of the bullet in the barrel. Some heavier bullets like Berger bullets definitely have a long nose. Also, weight distribution in the bullet as well as what material is in the bullet (i.e. lead or steel) can have an effect in bullet stability. Thanks for watching.

Great content

[@PracticalAccuracy]

thanks. for watching

[@mostrogolf22]

77 Blk Hills ammo is amazing. I clone this with 77gr SMK and 8208XBR. Very accurate. Playing eith 75gr Hornady HPBT Match projectile.

[@PracticalAccuracy]

Thanks for watching and I love Black Hills.

[@Blueknight1960]

Black hills ammo might be amazing but, for almost $2.00 per round for 62 gr 5.56 compared to .63 cents a round for pmc x-tac 62 gr green tip 5.56. I think the choice is obvious since my ar-15 is not a battle rifle. Now if you're a competition shooter, then it'll be a different story.

[@mostrogolf22]

No, you are absolutely correct, too expensive. I reload so it is way cheaper for me.

[@SteveLewan]

What happened to the crucifix?

[@andrewrudich6443]

What do you think about the S&W MP 2

[@PracticalAccuracy]

I think it's a good choice. Plus S&W has good customer service if there is a problem.

[@andrewrudich6443]

@@PracticalAccuracy Thank you, I want to get one before I can't, For multiply reasons.

[@PracticalAccuracy]

@@andrewrudich6443 thanks for watching. I hope the video helped.

[@CharlesHorning]

What is the best twist rate then?

[@PracticalAccuracy]

There really is no best twist rate. twist rates of 1-7,1-8, 1-9 should stabilize all bullets between 55 to 77 grains. however, a particular twist rate will not guarantee a particular bullet weight will be the most accurate in your rifle. I can only comment that based on shooting Rock River arms rifles, as seen in my other videos, with 1-9 or 1-8 twist, they are very accurate with 68 to 77 grain bullets. I have 2 criterion barrels in 1-8 twist that shoot 68 gr bullets the best, but 75 to 77 gr bullets not so good. You really just have to experiment. Hope this helps you.

[@CharlesHorning]

@@PracticalAccuracy Okay if I am on a strict budget and also because ammo is hard to come by do you recommend a twist rate that would work (theoretically) better on lower budget ammo?

[@PracticalAccuracy]

@@CharlesHorning if you are on a strict budget, I would recommend a Rock river upper 1-9 twist and put in on a cheaper lower. If you don't want Rock River and I had to pick only one twist rate, I would get a 1-8. However, I think barrel quality is more important than twist rate. Good luck

[@yjoeyyy]

I am also on a fixed income. Federal ammo is expensive if you can even find it. I wish I would learn to reload course that cost money to

[@PracticalAccuracy]

@@yjoeyyy Good luck. I know ammo is expensive right now.

[@ErikS308]

Use what you can find in 2021.

Unfortunately. Thanks for watching

[@brianleabo6295]

Alot winchester for one is loading the ammo soft !

[@CabinOnTheWater]

"Don't tell me I can't shoot that bullet through my rifle. I've got the empty brass to prove it!" lol

[@PracticalAccuracy]

lol. good point. thanks for watching.
