Cartridge Cutaways — View INSIDE Loaded Ammunition

sliced cutaway ammo ammunition FOG diagram

Here’s something you don’t see every day — the inside of loaded cartridges, sliced halfway through. This lets you see how bullet core, jacket, cartridge case, powder, and primer all fit together. Give credit to the folks at FOG Ammunition for creating this interesting series of cut-through ammo images. We show four cartridges here: the .308 Winchester, 9mm Luger, 300 BLK, and .50 BMG. You’ll find two more (the .223 Remington and .45 ACP) at www.FogAmmo.com.

This .308 Winchester 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.

This bisection is a 9mm Luger 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. This might look like stick powder, but those are in fact flakes stacked up in cross-section. Designed in 1901 by Georg Luger, this popular cartridge is used by civilians, military, and law enforcement.

For this model of the .300 AAC Blackout (aka 300 BLK), a Dremel tool was used to create a pie cut within the bullet and brass case. A measured amount of power, roughly 65% of spec charge, was placed inside the case with super glue. This cartridge was originally optimized for subsonic use with a suppressor, so the amount of powder used is small relative to the nominal case capacity. That leaves more room for the relatively large .30-caliber bullet.

Last but definitely not least is the .50 Caliber BMG round (aka .50 Browning Machine Gun). Famed for its wartime use in the M2 Machine gun, the .50 BMG round is also used in civilian Long Range competitions. A typical .50 BMG cartridge holds over 225 grains of powder. That’s almost ten times the amount in a 5.56×45 NATO Round! To demonstrate the size of the .50 BMG, check out that .223 Rem for comparison.

Two-Sided Sight-In Targets with Both MOA and MilRad Grids

sighting in sight-in target mil moa milrad grid reversible target
One side has MOA (Minute of Angle) grid for MOA-based scopes. Flip target over for MIL adjustment grid.

Here’s a clever product that can speed up the process of sighting-in your rifles, whether you have a scope with MOA-based clicks or an optic with MIL-based clicks. Sport Ridge offers a pair targets that are printed on BOTH sides with precise grids based on your scope’s click values. One side has an MOA-based grid while the other side of the target has 1/10th Milliradian grid.

Choose between two, double-sided printed targets: the 16″x16″ 100-yard Precision Rifle Target and the 10″x10″ 25/50-yard AR15 Sight-In Target. For both target types, side one has an MOA-based grid for scopes with 1/4-MOA or 1/8-MOA click values. Flip the target over to use the grid for MIL scopes with 1/10th Milliradian click values.

Sport Ridge’s Premium Precision Sight-In Targets allow you to adjust the point of impact quickly because the target’s grid boxes precisely match the click values of MOA and MIL measurement systems. Sport Ridge states: “No more guesswork at matching your optic’s adjustment value, saving your ammunition and time spent sighting-in firearms.” Get the 16″x16″ Precision Target 8-pack for $7.99, or the 10″x10″ AR Target 10-pack for $5.99.

Manufacturer Video Explains How to Sight-In with MOA/MIL Grid Target:

This has a large center sighting bullseye so it can be used to confirm MOA-based click values at longer ranges (300+ yards) with rifles. Or use it at close range (for 10, 25, or 50 yards) for red-dot equipped pistols or shotguns. A 10-pack is $5.99, or get a 25-pack for $13.99.

plano airglide vertical top open rifle case
⏺ Get the last ones! Great range case, but no longer in production

The Plano Airglide is a unique, vertical-loading rifle case. The rifle is supported by foam blocks so there is no side-pressure on your scope turrets. The AirGlide’s hinged top-opening lid provides clearance for all but the most massive target scopes. Airglides are VERY popular with our Forum members, and this Editor uses Airglides to transport his own rifles to the range. Unfortunately, Plano has halted production of the AirGlide case. However, there are still a few available from Champion’s Choice for $58.00 (plus shipping) or from Amazon for $71.75 (free shipping). Grab one while you still can!

Plano Air-Glide Rifle Case

Sunday GunDay: .22 LR Conversion Kit for AR-15 Platform

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

Over the past 18 months, popular ammo types, such as .223 Rem and 9mm, have been hard to find at reasonable prices. The high cost of .223 Rem centerfire ammo has driven more folks to shooting .22 LR rimfire ammo, both for fun and practice. This Sunday we look at a smart solution that allows you to shoot .22 LR ammo from your existing .223/5.56 AR-15 platform rifle. This is great because it allows low-cost training with no change in rifle balance, ergonomics, and/or optics.

The CMMG Bravo .22 LR Conversion Kit provides a replacement bolt/bolt carrier along with three 25-round magazines with special .22 LR-fitted followers and ammo slots. This allows you to shoot rimfire ammo from any AR-15 chambered for the .223 Rem (5.56×45). The CMMG Bravo has an integrated extension that fits into your current chamber. The rimfire bullet passes through this extension and then enters the barrel.

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition
The CMMG Bravo conversion Kit comes with blowback-operated .22 LR bolt carrier, rubber protector for bolt carrier tip, and three 25-round polymer magazines. To use, simply replace the rifle’s .223 Rem bolt and carrier with the Bravo .22 LR conversion unit and load up the included magazine(s) with rimfire ammo.

To use the CMMG Kit, simply remove the centerfire bolt/bolt carrier, and replace it with the CMMG silver colored bolt shown above. CMMG states: “For best performance use a round-style hammer as notched hammers can cause function issues.” Testers have stated that high-velocity .22 LR ammo works best, and CMMG notes that “36gr plated-nose bullets have proven to be the best choice for function.” The copper-plated bullets help reduce fouling.

Ultimate Reloader Tests CMMG .22 LR Conversion Kit

Our friend Gavin Gear of UltimateReloader.com recently tested the CMMG .22 LR AR Conversion Kit. He observed that installation was very straight-forward and the CMMG magazines worked well. He and fellow tester Travis Fox shot the unit both slow-fire and rapid-fire successfully.

Gavin and Travis found the CMMG Kit easy to install and fun to use. With an AR that can shoot both .223 Rem and .22 LR, it’s like having “two guns in one”. Travis was impressed with the ease of use: “It is so simple to change over to the CMMG .22 LR AR kit! It took me about 68 seconds the very first time I tried. Each time after that it took me about 40 seconds — it’s that simple. It takes longer to fully load one of the mags than it does to switch over from .223/5.56 to .22 LR and back.”

The AR shot very well with the higher-velocity ammo types. 100% functioning was achieved with both 40gr Federal Game Shok ammo and American Eagle High Velocity 38gr Copper-plated HP ammo. NOTE: CMMG does recommend high-velocity Copper-plated rimfire ammunition.

Maintenance Tip — After converting back to your centerfire .223 Rem (5.56), Travis says “make sure to clean the gas tube and components as .22 LR tends to run dirty”. READ Full Test on UltimateReloader.com.

CMMG Bravo Conversion Kit Gets Thumbs Up from Gavin and Travis
“Does this conversion kit get the Ultimate Reloader stamp of approval? Absolutely! In these times of ammunition/component scarcity this gives options to shooters. Finding bulk .22 LR can sometimes be easier than 223/5.56. This kit gives that option at a great price. Any chance to keep skills up and familiarize new shooters to a platform is a good thing. Basically two rifles for a lot less than another rifle.”

How to Install CMMG Bravo .22 LR Conversion Kit

The Brownells video below shows the installation process step-by-step:

In this instructional video, a Brownells gunsmith demonstrates (step by step) how to install, disassemble, clean, lubricate, and reassemble the CMMG AR-15 .22 LR Conversion Kits. Clear the rifle and make safe before you start the conversion. Separate the upper and lower, remove the standard bolt carrier group. You then install the conversion bolt and connect the upper and lower as normal.

Details of CMMG .22 LR Conversion Kit

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

“For years I’ve had a CMMG conversion kit. It’s a drop-in system that’s … very reliable and it’s accurate. The [CMMG conversion] has lower recoil [and is] great for training. Even though ammo prices have gone through the roof, .22 LR is still cheaper to shoot than anything else.” — SootchGear

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

This SootchGear video shows how to install the CMMG Bravo unit. The video also compares the original CMMG .22 LR bolt assembly with the latest integrated CMMG Bravo at 2:00-3:50. The older unit had a brass adapter and separate chamber insert. The host also tests a CMMG-equipped AR with various types of ammo. Watch a rapid-fire sequence starting at 1:48 time-mark.

Field Test with Two ARs — Rapid Fire .22 LR Testing

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

The video below demonstrates rapid-fire .22 LR performance with two different ARs using CCI Mini-Mag ammo. The CMMG conversion is fast and easy: “In a matter of seconds you go from 5.56 to .22 LR”. Watch rapid-fire at 5:40 with CCI Mini-Mags in red/black rifle. Then the tester shoots a variety of ammo in a .223 Wylde-chambered all-black AR, starting at 9:40. The Mini-Mags worked flawlessly, but there were a couple fail-to-cycle sequences in extreme rapid-fire with cheaper “bulk” ammo. The lesson here is use good quality, high-velocity ammo.


NOTE: This 2018 video shows an earlier CMMG .22 LR conversion bolt that features a brass adapter and separate chamber insert. The current CMMG Kit has unitized bolt without a separate adapter or insert.

Interestingly, the Mini-Mag .22 LR ammo shot fine in the .223 Wylde-chambered AR. However, CMMG cautions: “Since .223 WYLDE is NOT a mil-spec chamber, we cannot guarantee fit or function with our 22LR conversion kits.”

Reviews from CMMG Bravo .22 LR Rimfire Conversion Kit Purchasers:

“Get it. Bought this for my Rock River AR. Bolt system goes in [easily] and fits perfectly. Took it to the range and put over 150 rounds through, only failing to feed/fire two rounds. I most definitely recommend this product to anyone looking to shoot their standard AR-15 .223 rifle on a budget.” — Pew P.

“I got this just yesterday and in two days time I have put a couple thousand rounds through it and no hick-ups. I have no complaints.” — Seth

“Best buy for anyone during this ammo crisis. Ammo is extremely expensive and hard to find. It was a ‘no-brainer’ once I found this kit. Ran 200 rounds to break it in for about $20 and had maybe 3 failures. Accurate up to 50 yards (I haven’t tried further) without optic adjustments.” — Joshua M.

“Purchased one of these in January. Took it to the range shortly after for my daughters to try out. We have three ARs and this thing functioned flawlessly. We practiced swapping out the 5.56 carrier with this back and forth, flawless. Enjoyed it so much now I’m purchasing another one.” — J.B.

“Great product. I bought this due to the high cost of ammo. I wanted to still shoot my AR and this was an alternative. This thing works great… works flawless with different types of .22 LR, from premium CCI to the cheap stuff. I recommend this to anyone thinking about getting one.” — Thom

* You can get also CMMG Conversion Kits from Brownells with one (1) 25rd mag for $219.99, or with three (3) 25rd mags for $249.99. There is also a CMMG kit with three (3) 10-rd mags for $249.99 for areas with capacity restriction.

Giant 14.5x114mm Cartridge Dwarfs .338 Lapua Magnum

14.5x114 mm cartridge Russia South Africa
Photo courtesy Elardus de Lang, Truvelo Manufacturers Armoury, South Africa.

Believe it or not, here is a cartridge that makes a .338 Lapua Magnum look like a toy. The 14.5x114mm cartridge was designed as a MG and rifle-fired anti-materiel round. To translate from the metric system to caliber and inches, the round is a mammoth .57 caliber which measures 4.49 inches to the case mouth, and 6.13 inches overall. That jumbo-sized case holds a whopping 655 grains of powder. Commonly-loaded projectiles weigh 920-1030 grains. The 993gr armor-piercing projectile has a muzzle velocity of approximately 1006 meters per second (3300 fps) and can penetrate 30-32 millimeters of RHA steel at a range of 500 meters.

The top photo comes from Elardus De Lang, a Forum member who works at the Truvelo Manufacturers Armoury in South Africa. Elardus also provided an impressive video showing the massive 14.5x114mm being shot from prone with a Truvelo-built bolt-action rifle. Elardus tells us: “Here is a video, with a slow-motion ending, of our 14.5x114mm anti-materiel rifle being fired in our indoor testing facility. This caliber is a true beast! It propels a 993gr Armor-Piercing Incendiary bullet to 3300 fps, burning 480 grains of powder in the process. [This shows] that rifles of that power level can actually be shootable. The concussion indoors is something to experience……every shot feels like you are being punched in the face, and the heat from the muzzle flash actually hits you like a wave!”

14.5x114mm Cartridge Design and Dimensions
The 14.5×114mm has 42.53 ml (655 grains H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under extreme conditions. Cartridges typically use lacquered steel cases, but some countries also use brass cases for the 14.5x115mm.

14.5x114 mm cartridge Russia South Africa

All dimensions are in millimeters (mm). Americans would define the shoulder angle at alpha/2, or 22.5 degrees. The common rifling twist rate for this cartridge is 455 mm (1:17.91″) with eight lands/grooves. According to official guidelines, the 14.5×114mm can handle up to 360 MPa (52,213 psi) piezo pressure.

14.5x114 mm cartridge Russia truvelo manufacturers armoury South Africa

14.5x114mm Cartridge History
The 14.5×114mm (.57 Cal) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries. It was originally developed for the PTRS and PTRD anti-tank rifles, but was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of the BTR series of armoured personnel carriers from the BTR-60 to the BTR-80 and for heavy anti-material sniper rifles. The cartridge was designed in 1939 and first issued in 1941.

In this short article, Dennis DeMille, a past Service Rifle Champion, explains how to set-up a sling on match rifles.

Setting-Up a Leather Service Rifle Sling for Competition
So you made the mistake of disassembling your leather service rifle sling, or are intimidated about how to use one? In this Creedmoor Sports InfoZone video, Dennis DeMille (past Creedmoor G.M.) explains how to set up and use a sling. The covers the basics — Dennis starts with a totally disassembled leather service rifle sling and shows you how to set it up properly.

Tip: “Many shooters shy away from using a leather sling because they have never been taught how to use one. That’s unfortunate. In my opinion a leather sling offers more support than a web sling, which is important when competiting with the heavier than normal rifles.”

Configuring the Sling for the Standing (Offhand) Position
In this second in a series of Creedmoor InfoZone videos on the setup and use of the leather service rifle sling, Dennis DeMille details how to configure and best utilize the leather service rifle sling while shooting from the standing position.

Tip: “Putting the Frogs in different hole will change the amount of added elevation a sling provides.”

Looking at Sling Types — Comparing the Features
In this video Dennis showcases a large variety of shooting slings. He explains the strong points of each type so you can choose the sling best suited to your discipline and shooting style.

Dennis DeMille High PowerThe Benefits of Dry-Fire Training
Once you know how to set up your sling properly, you’ll want to practice. Dennis DeMille stresses the importance of dry-fire practice with sling and shooting coat. Dry-Fire training is essential to the sling disciplines. Dennis DeMille, a national Service Rifle Champion, told us that, for every minute he spent in actual competition, he would spend hours practicing without ammunition. While in the USMC, Dennis would practice in the barracks, working on his hold and dry-firing:

“The most important thing is to spend time off the range practicing. Most of what I learned as a High Power shooter I learned without ammunition — just spending time dry firing and doing holding exercises. Holding exercises will really identify the weak parts of your position. The primary purpose of dry firing is to get you used to shooting an empty rifle. If you can shoot a loaded rifle the same way you shoot an empty rifle then eventually you will become a High Master.”

“Can Do” — How Modern Suppressors Are Made — Step by Step

Silencerco suppressor factory video production metal fabrication can silencer baffle
Image from SilencerShop.com Octane 45 HD suppressor review. SWR is now a part of SilencerCo.

Here is a cool video that shows the entire production process for a SilencerCo Octane pistol suppressor start to finish. Beginning with the raw materials, this video shows a wide variety of cutting, milling, drilling, burnishing, fitting, metal bathing, surface finishing, and laser etching processes.

If you have any interest in production methods you’ll want to watch this video all the way through, and maybe a second time.

SilencerCo states: “From cutting metal to chemical baths, to extensive quality control every step of the way, our streamlined process is more than just a few steps.” We think you may be surprised by how many steps are involved in producing this silencer (aka “suppressor”).

The Octane is a user-maintainable, multi-caliber centerfire pistol silencer featuring a modular mounting system for use across a wide range of hosts. High strength, stainless steel CTA™ (Click Together Assembly) baffles are easily disassembled for cleaning. This design makes the Octane one of the most durable small-caliber suppressors on the market.

In its Octane 45 review, SilencerShop notes: “When it comes to ease of maintenance, the Octane 45 is probably the simplest .45 suppressor on the market. It uses the new click-together baffle system from Silencerco/SWR – which allows the suppressor to come apart like a monocore suppressor, while providing performance that is closer to a K-Baffle design.””

Store Your Cleaning Rods with Handy Fishing Rod Racks

Fishing Rod Rack Cleaning RodsForum member Nodak7mm has discovered an ideal way to store your rifle cleaning rods in your garage or loading room. Using inexpensive Berkley Horizontal Fishing Rod Racks, Nodak7mm has secured a half-dozen Dewey rods on the back of a door. You could also mount the racks along a wall or on the side of a storage cabinet. This installation takes up minimal space and the Berkley Racks cost just $11.22 at Amazon (select “6 Rod Rack”) or $11.64 per set at Walmart. If you prefer wood, Amazon also sells a pine 6-rod wall rack for $22.45.

Nodak7mm explains: “I was moving some fishing poles around and ended up with an extra pair of Fishing Rod wall racks. I said to myself, ‘I bet this would hold my Dewey cleaning rods’. I mounted the pair on the inside of a closet door in my man cave and put my cleaning rods in it. It works like a charm and is far cheaper than a specially-made rack that only lets the rods hang. One can even slam the door with the rods mounted and they stay put. This rod rack set… is made by a nationally recognized name and does a great job of holding the cleaning rods securely and safely.” These are inexpensive and are easy to mount to a door or wood cabinet.

Stow Your Cleaning Rods on Your Gun Safe
Another option is to make a rod set with a magnetic backing strip. This can be affixed to the sides of your gun safe or steel storage cabinet. Here is a home-made, magnet-affixed cleaning rod holder made by Forum Member “BobM”. This smart installation works great. CLICK HERE for more information.
