Six Popular Rounds Cut in Half

2BQxBAy

I love these cutaway pictures, one of my favorites is that picture we posted back in 2014 from the UK of that Webley Mark IV .38/200 revolver with the barrel obstruction that was cut in half. Well when I stumbled upon this awesome new post from Fog Ammunition with high quality pictures of ammo cut in half I had to share it. Their recent post shows six popular hunting, shooting and self defense rounds cut in half. Check them all out below.

.223 rem on the LEFT, 5.56 Nato on the RIGHT.

Bullet weight: 45 to 77 grains. Bullet style: Various Velocity: 2750 – 3750 fps Year Designed: 1964 This popular round was the first to be bifurcated, showing the base internal components of the popular cartridge. The process was as simple as using a hacksaw to bisect and a belt sander to polish. To the naked eye the differences are nearly indistinguishable aside from annealing of the .223, some people also say they can see the crimp in the primer pocket of the 5.56.

9mm Luger

Bullet : 9mm Luger 125 grain Sierra Jacketed Hollow Point Velocity: 1090 fps Year Designed: 1901 This bisection is a 9mm Jacketed Hollow Point round with flake powder held together with super glue. After this self-defense round was cut by a trained professional the round was polished by hand. Some think that the powder looks like worms or sticks, but it is in fact the flake stacking up on itself to give you an inside view! Designed by Georg Luger, the round is heavily used today by civilians, military, competitive shooters, and law enforcement.

45 ACP

Bullet: 45 ACP 230 Grain Berries MFG. Round Nose Velocity: 850 fps Year Designed: 1904 One of the most popular calibers of its time, the round was first developed in for use in John M. Browning’s 1911 Automatic Colt Pistol, and is still used today by shooters and military alike. Taking on the artistic eye of a still life photographer, this picture captures three different stages of the popular 45 ACP round. The powder your see spilling from the pie cut round is to represent the specifications as if the rounds were loaded properly and not cut in half.

300 AAC Blackout

Bullet weight: 300 AAC Blackout 220 Grain Sierra Hollow Point Boat Tail Bullet style: Hollow Point Boat tail Velocity: 1050 fps Year Designed: Early 1990’s First designed for special operations groups needing more stopping power, for this model of the 300 BLK a Dremel tool was used to create a pie cut within the bullet and brass case. A measured amount of power was formed inside the case with super glue, which displays roughly 65% of spec charge. Ever popular with the use of a suppressor, the low amount of powder is due to the rounds subsonic capabilities of traveling below the speed of sound at 1126 feet per second.

.308 winchester rounds

Bullet: 308 Win 168 grain Sierra Hollow Point Boat Tail Velocity: 2800 fps Year Designed: 1952 This model took on a different approach by only cutting the brass case and displaying the full bullet, primer and powder load. A spec amount of powder was used to create the model powder form. An estimated 10% volume was added during the forming process, along with an undetermined amount of air pockets.

50 BMG

In comparison: .223 Rem 55 Hornady Grain FMJ on the LEFT, 50 BMG on the right. Bullet weight: 750 Grains Bullet style: FMJ Velocity: 2800 fps Year Introduced: Late 1910’s Last but most definably not least is the 50 Caliber BMG round. Infamous for it’s use in the M2 Machine gun and capable of reaching a maximum ballistic range of 7,000 meters. The round has proven its dominance in nearly every major conflict in the world for over one century. A typical round uses over 225 grains of powder. That’s almost 10 times the amount in a 5.56 NATO Round!

    Different view on ammo…

  • Disarmed in CA

    Cut in half, like my bank account whenever I purchase ammo. Cool pics!

    • Gary Kirk

      Every time I save up enough to get a bunch of ammo, I wind up with another gun.. Still feed my supply on a trickle charge.. Amazing how much it builds up now that I’m married and have a daughter.. No more range 3-5 days a week..

      • DanGoodShot

        I have 4 kids and an ex-wife. Somehow, I ended up with the kids!(thank god.) I still get to the range a couple times a week. My trick to it… 1. I reload. A lot. Kids do it with me. They sort brass by cal. and headstamp, decap, tumble and a few other assorted small tasks. 2. I bring them with me to the range. My 7 year old little tomboy keeps my rem700 .308 in a half dollar sized hole at 100 yrds! The 8 year old Miss Prissy Princess burns through 5.56 but maintains tight groups (I should say clusters! lol). My 5 year old lil man is just starting out on the 10/22 but keeps em’ in the black @ 50yrds. My 2 yr old has a couple years to go. But if it was up to her, she’d be on it!
        If you go 2-3 times a week, Bring em’ with you 1 or 2 of the times. It makes for a great time and helps get new shooters into it and you get more range time. Not to mention the memories you’ll make along the way. All benefit, no down side.
        I also noticed my shooting impoved a lot when I started teaching them to shoot.

        • Gary Kirk

          You begin to remember the fundamentals when teaching new shooters.. Especially when you care, would love to take both my wife and 3 yo little monster to the range.. But due to money constraints, can only get them out to the farm here and there. Everyone’s life is different, and your story gives me some hope.. Teach them young, teach them right, and we may just have a future.

          P.S. Here she is @ think it was 18 months.. Helping daddy. https://uploads.disquscdn.com/images/9902488b1dbc093b3dd7c0bf5cecf3b3aa9d3d9dcc080d073c38f1a9a893a3bd.jpg

          • Gary Kirk

            K, don’t know why this is upside down, and no she doesn’t have any chemicals.. And the rifle is clear, and clean..

          • DanGoodShot

            Don’t sweat it. I’m always making upside-down/sideways videos. Its amazing how they defy physics and get us wrapped around that tiny little pinky. She’s adorable and ready to go! lol. I was talking with an officer/father in my town about kids and guns. We both believe in over exposure and teaching them young. It gets them into something positive, constructive and helps keep 2a alive. I hear you on the financial aspect of it. I’m fortunate my range charges $4 an hour. They also let me pick the buckets for brass. A few of us pool our money together to buy in bulk. Saves us a ton. Your absolutely right about it helping you focus on the fundamentals. For me, It’s trying not to be out shot by my 7yr old! She’s a natural.

          • Gary Kirk

            Gotta love it

          • gypsy

            As a father, if your 7 year old outshot you, I know you would be the proudest father on this planet.

          • DanGoodShot

            You got that right. 1st time out I put 2 “eyes” and a “nose” on a paper silhouette, just to make it a little more entertaining for her. Next time we went out… she matched me! Lol.

        • Shocked_and_Amazed✓ᵛᵉʳᶦᶠᶦᵉᵈ

          Good for you Dan! God bless you and yours.

        • Jim Kiser

          Way to go Dan! We have to start the next generation of shooters early. The first few times I took my little ones out to shoot they had to use a tree branch for a rest. They couldn’t hold the guns up long enough or steady enough so we improvised. My Son was 5 and my Daughter was 7 when they started shooting and I found out as long as I took them shooting or fishing every I could they were happy. My Daughter of course liked shooting more but oh well. Now they’re both in their mid twenties and one of them has a great family and they’re teaching their kids already which I find awesome. Both my kids still to this day love a day at the range and I pray that never stops. They grow up fast so please enjoy it while you can with the munchkins.

          • DanGoodShot

            Thank you! We sure do if want to keep our 2a. It also takes the curiosity away. My kids know what a gun can do and how to treart them. They can’t hold them to well either. I have a few bi pods and sand bags. It helps a lot! Without those they wouldn’t be able to enjoy it and I wanted to make sure they did. My oldest grumbles when I take her, once there she has a blast and dosen’t want to leave! Kids. Lol.
            1 thing I’ve learned about kids and time is having kids is like hitting the fast forward button on life and the more you have the faster it goes. I will and I do enjoy every minute of it. Same to you and yours! Its good to hear it gets past on. I prey my kids do the same. I try to teach them the importance of it as well because I know the schools are not going to do it.

          • jcitizen

            You have a wonderful family life Dan – Kudos to you and the kids!!

        • OBlamo Binlyen

          Heh, I took the grandkids to range a few times with a 10/22 and a couple of .22 pistols. Then, being a doting grandpa, built them up a couple of AR’s, Did one in Pink for the 10 year old, now I have to re-furnish it in Purple, FINALLY they have PURPLE. I didn’t even bother with 25 yards, straight to 50 with a red-dot. Sadly residing in Kommieforniastan’s S. Bay Area it’s hard to go to a range or even have a place to shoot in the urban areas, unless you are a thug, then….who cares.

          • DanGoodShot

            lol. “Thug.” I feel your pain. I live in the east coast equivalent. Good old Commienecticut. I’m fortunate the range I use is shared with the local pd and (for now anyway) they are pro 2a.
            My daughters started as pink, now it’s “baby” blue. My mother always said, “your reward for being a parent are your grandchildren.” Enjoy every minute! Till I’m a grandparent my reward is watching their little faces light up every time they squeeze the trigger.

          • Bonzaipilot

            Castro Valley has a decent range but Livermore by far outweighs CV. It’s a bit of a drive but not too bad compared to where some people have to go like those of us stuck in San Diego now

        • Old Vet

          Thank you for teaching your children. We need many more parents of like mind. I got my boy from my much younger ex-wife when he was 12 and saved him from being a prissy Momma’s boy. People came to me later and said they thought he was going to gay side until I rescued him. I give a lot of credit to the new friends he developed once he was with me too. He is getting ready to become an Army Medic this year. I am proud.

          • DanGoodShot

            Thank you. I fully agree. Something about those younger womans brains, my ex was much younger as well. She just flaked out all the sudden. Eh, fine by me as long as I have the kids! lol. You should be proud. Thats something to be proud of! I’ve already mentioned the military to my kids. They get a kick out of seeing old pictures of me in my cracker jacks. All you can do is your best the rest is in gods hands. Sounds like you did that.

      • gypsy

        reload time when purchasing a supply of ammo costs as much as a new firearm. Although the idea of a new firearm is always more appealing, ammo can always be gotten.
        I remember my father having a problem; when he had a cartridge and no firearm that matched the caliber, he had to go out and buy one.

        • Gary Kirk

          Have actually been there.. A friend had his basement flood, lost a couple firearms in that.. But all his ammo stayed dry, gave me a trashcan full of this and that.. Wound up most of it was .38 … So what’s one to do?.. I went and bought a .357 of course. Used all he gave me, now am stocking up on .357

          • gypsy

            Life’s tough, isn’t it.

  • Rick O’Shay

    This didn’t come from reddit? Saw it there yesterday or the day before.

  • PeterK

    WOAH. Awesome.

  • DanGoodShot

    Does anyone else think the .223 and 5.56 are backward? The one on the left looks to be the 5.56 and the right the .223. Not only due to the obvious annealing(yes, there is annealed .223, but not as common) If you look just above the base, the case wall looks thicker than the one on the right. Thicker brass is indicative of the 5.56.

    • John Yossarian

      You’re not alone in that – I saw the thicker case wall on the left and just assumed my eyes were getting old.

    • Sunshine_Shooter

      The fact that they could be backwards, maybe, if you really look carefully, is why I use them interchangeably.

  • Anonymoose

    You can get bullets heavier than 77gr for the 5.56/.223. 80gr is common but usually not loaded to mag-length, Barnes came out with an mag-length 85gr, and there are those 100 and 110gr subsonics (with over twice the energy of a .22LR!!! lol).

  • Sunshine_Shooter

    Some people are wondering if the .223 and the 5.56 are backwards. Can you confirm their positioning is correct?

    • Nic Johnson

      Hey Sunshine_Shooter. When my machine shop guy cut these and handed them to me I got them wrong as well! That said, the original picture is labeled correct as headstamps don’t lie as far as manufacture identification goes. (.223 on LEFT, 5.56 on RIGHT) I’ve added a pic that I just took on my desk with the brass where you can see the headstamps: Same dissected brass, .223 LEFT (.223 G.F.L “Fiocchi” Headstamp), 5.56 RIGHT (Lake City Headstamp)

  • William Elliott

    Ummm, IIRC, the .223 is NOT annealed, but the 5.56 IS. In fact I think I have some NATO surplus around here somewhere…

  • Dr. Obvious

    the powder difference between the 300 and the 308 is astounding.

  • jcitizen

    WTF??

    • Suppressed

      The first is some 35mm rheinmetal(sp?) round and fhe second is 9mm armor piercing from the 70’s.

      • jcitizen

        Thanks, I’ll have to read up on that Rheinmetal round! Wiki said it is called AHEAD, and throws the sub munitions out to destroy incoming missiles. The round can destroy cruise and other high speed missiles from 1.5 to 2.5 km!! Made by RWM Schweiz AG for the 35mm gun system. That’s some pure hell there! I wonder how it stacks up to our Phalanx CIW?

        • Blake

          The Phalanx isn’t a great system overall, so I bet pretty well.

  • jcitizen

    That 50 bmg bullet looks like it has stuff packed in the nose – I wonder what round? Can’t be an API because there is no base composition. Those used to be made of tungsten in the old days, I bet only a grinder could cut it. I believe the plain old ball rounds are 650g, but I’m not sure what the weight difference is between lead and steel ball bullets. Most of my loose military ball bullets are steel core.
