And 1/7 burns out the barrel much quicker than 1/9, which is perfect for m855 62 grain. Twist rate is determined by length of the bullet, not the weight. “Green Hill formula”
For most Americans with an AR15, the m193 bullet (55gr FMJBT) is the most versatile and fulfills most of the needed requirement (self defense, plinking, and survival hunting) with this rifle and bullet combination. An added benefit with the M193 bullet is its tendency to tumble and fragment upon impact from common building materials which reduces over penetration through structures when compared to common FMJ bullets when used in the 9x19, 45acp, or other common rifle calibers.
This video has a WAY better explanation of which twist rate is best for a particular barrel length and bullet weight. This video is better than the Tech Tips video on the same topic.
And this is the reason I only take advice from Brownells people, because finally someone gives the correct information about bullet twist rate. Thank God for you guys...
Right now I have quite the ammo smorgasbord since my local shop will only let you buy two boxes of each SKU# of ammo ha! I actually like that they do that so scalpers can’t hoard and resell boxes for profit.
I work at a gun counter/ammo counter at a store. PLEASE do a video explaining that match grade target ammo HP's are not really suited for hunting. This last week I have had to explain to four customers that the 308 Sierra Matchking load is a target load and will not reliably expand to offer a humane kill.
Military rounds are FMJ ball ammunition. It does the job and usually takes more than one out of the fight as one or more will now be required to assist a person to medical care or remove them from the battle field.
@Joe John is that a response to me or Glory bound I also forgot to add to my response earlier normal armies they have Medics which are trained to treat Battlefield wounds and if that's their job than being taken out of the fight
I use MK262Mod1. FMJ is far better than hollow points in 5.56, fragmentation is how that caliber is effective, only FMJs will fragment like that. (Note MK262 uses the 77 grain SMK, it’s technically an open tip match round but it behaves like an FMJ.)
@@literallynobody1515 IMI Razor core is the same thing. Loaded to the same specs. I think Midway USA had some, the last time I checked, although I got mine from SG Ammo.
@@VCBird6 Except it’s not lol Fragmenting FMJ does WAY more damage. Unless you are talking about a short barrel or very long range were the velocity is under what’s required for fragmentation.
@@cplinstructor Might wanna check video of what soft points do to squishy targets vs FMJ. The only and the ONLY thing that FMJ can do better than soft points (and only out of a rifle length barrel and within 50 yards or so) is defeat level III+ body armor. Otherwise, soft point expands, yaws, shatters, and fragments even BETTER than FMJ, depending on bullet construction.
Hi Jeff: I know your trying to cover a vast number of topics here but thought I'd mention that more spin does not always equate to more bullet stabilization as indicated at 1:25. Bullets that are spun to quickly or to slowly won't be stable as it travels downrange.
@@masonjohns208 because 223 wylde runs both 223 and 556 really well. 556 runs both but 223 performance suffers slightly through a 556. hence the 223 wylde being created. IMO they should all be 223 wylde but i guess it is more expensive
Just had a rude interaction with customer service via email. I am a polite and loyal person. I expect the same from others. Brownell’s lost a customer today.
a lot of people are using 10.3-11.5 inch barrels for self defense, this video doesn’t address that. If you’re watching this and want a short and easy answer to “what do buy for a 1 in 7 twist, 10.3 to 11.5 inch gun” then go look into 77 grain speer gold dots
I've Only Seen A 1/12 Twist Rate AR-15 On YT (Military Arms Channel); I Have Never Seen A 1/12 Twist Rate AR-15 In Person Or On An Online Gun Shop. However I Have Seen A 1/7 Twist Rate, A 1/8 Twist Rate, And A 1/9 Twist Rate. My AR-15 Currently An Upper Assembly With A 1/7 Twist Barrel; My Original Upper Assembly Has A 1/9 Twist Barrel (I Still Have My Original Upper Assembly). I Know Someone Who Owns A 1/8 Twist AR-15.
You can't use an AR 15 for hunting. At least in kanada. Our pride minster says so. And he knows all. Fight for your few remaining rights, brothers! Oh. now, it's illegal to *OWN* an AR in kanadastan. Stay well.
In Michigan you can use most any rifle including AR platform rifles. Just make sure the magazine can only HOLD 5 rounds or less. Rule is 5 in the magazine, 1 in the chamber.
@@phprofYT We in kanada have a 5 round limit as well. 3, in shotguns. Just that some "weapons" have been deemed unsuitable for us peons to own. Stay free!
The People’s Republic of Kanadastan. We will fight like hell to reverse this Red Tide. (Not to be confused with the Crimson Tide. That’s a whole different story. )
M193 is a frangible round that yaws on impact making as deadly self defense round as any hollow point. If it’s good enough for the enemy it’s good enough to stop a unwanted intruder.
Unless you're shooting it out of an SBR or AR pistol, especially with a barrel less than 10.5 inches, then you're just poking 5.56 holes. Soft points fix that problem
"if it's good enough for the enemy" is a silly wall to hide behind - Hague convention outlaws the use of more effective expanding bullets in major conflicts, so I'll definitely take any advantage that I can (especially ballistic tips!)
Short barreled category is not hard to get ahold of as long as you have the obvious pistol brace. Also I'm sure Jeff is also aware of even shorter barrels than 10.5" for .223/5.56
There was a chart with Twist rate on one axis and Grain on the other axis and it gave "Good" "OK" and "Not really" ratings... wish I could find it online again.
Great video, Jeff, thank you. Is there any functional difference between soft points and hollow points for 223 for self defense? Which is best for avoiding over penetration?
Be careful with soft points. Some but not all feed ramps will bang up soft points causing a failure or tip damage resulting in a slight decrease in accuracy
Many Leo’s use Hornady “tap” rounds(red tip) they don’t over penetrate and I think they are polymer tip? Idk perfect round for home defense scenario if you use an AR.
Since this is prob directed at new shooters/gun owners, you've stirred a bunch of stuff into the pot thats confusing. 1. The proper caliber will be stamped on the barrel. 2. Use that caliber and find the brand that functions flawlessly in your rifle. 3. Educate yourself on how to maintain your firearm. None of the above matters if you don't.
I'm no wiz at all when it comes to rifle builds etc. My question is; say you have a direct impinged 16" barrel. Can you cut it down to say 12" without affecting the gas block system etc.
Look up dwell time. It's basically the time span when the bullet passes the gas port until it exits the barrel. Not enough dwell time equals not enough gas for proper bolt function. You could always enlarge the gas port if you want to go that route.
If your barrel is less than 16” it changes the legality of it. You need to by a dedicated AR pistol lower to use the shorter barrels while staying legal. Some states restrict AR pistols and currently the ATF is trying very hard to limit their availability and scope.
Watched a video of a 1-9 twist shooting a 77 grain bullet at 567 yards on a 15 Inch metal plate so people be careful of what people tell you and they will tell u can't shoot heavier bullets on a 1-9 twist rate not saying 55 grain is not better for that rate but do your own researching and learn that's what I done..
I just read a lengthy article based on tests that said overall, soft points expanded reliably to about .45 inches, even in barrel lengths under 10 inches.
5.56 and .223 ARE NOT identical ! If you shoot 5.56 through a barrel designated .223 only, it will ruin that barrel, and eventually You ! That was a negligent video !
Not true. Most 5.56 loads are equivalent to .223 Remington proof loads. Show me any .223 that has blown up with a factory loaded 5.56. That said, I only purchase 5.56 pressure ammo and all my guns have 5.56 chambers.
@@dbmail545 Look pal, I'm aware that the .223 only barrel isn't common these days, but they exist . 5.56 has an extra thousandth of an inch in diameter over .223.
223 Wylde is a hybrid designed to use either 5.56 or .223. The weight will depend on twist rate mostly. A faster (1/7) twist will normally stabilize the heavier (68-77) bullets better and a slower (1/9) will generally stabilize the lighter (55-62) better. Although more uncommon a 1/8 twist will generally stabilize them all. That said, you will have to buy different ammunition and just try them to see what your barrel prefers. But those should get you a good starting point. Hope this is what you were looking for.
@@christoperdevore3617 Thanks. Very well done and thorough reply. I knew the answer, but was just a little disappointed it was not addressed in the video and thought it would've been good for others who may not know. But, you addressed it well here with your reply.
@@patricjft well, thank you very much for the kind and hopeful accurate critique. I try to to keep my pie hole shut on topics I’m unfamiliar with but try to help if I feel I can. Your feedback is much appreciated.
Yes. You can commonly find soft point in 62gr, though I'm sure there is more variety available. From cheap plinking 35gr to 77gr match, they can be had in open tip, hollow point, and polymer tip.
55 grain soft points cranking along at 3000 fps will get pretty well anything done within 200 yards (short of putting Yogi on his butt, of course haha)
@@jakewolynski5239 pick a better round if you want to shoot at those distances. 5.56 isn't going to be shining very well after 200 in a 16in barrel or less as most people use. 300 if you use a 20in. After that better off using a .308/6.5creed or many others
Where did you get that silly idea? Are you in Russia? I have heard that CIP doesn't distinguish between 5.56 and .223 but you are looking at higher pressures in a looser chamber.
