Eye in the Sky — Drone View of 1122-Yard Shooting Session

Texas .223 Rem Drone Video 1000 Yards Gorilla Ammo

Many of our readers have never had a chance to shoot much past 600 yards. How far away does a 1000-yard+ target really seem to the naked eye? Well this short video answers that question. Gorilla Ammo, the video’s producers, used a camera-carrying aerial drone to fly downrange from the firing line all the way out to 1122 yards (and back again). Watch the drone footage at 0:00-0:07 and especially 0:48-1:03. The “bird’s-eye view” really gives you a sense of the distance. The “fly-back” at 0:48-1:03 time-mark is what makes this video worth watching.

The video features prone shooting at steel targets placed at 750 and 1122 yards. We do apologize for the lame, “oh so serious” voice-over which attempts to make this rather ordinary range session seem like some kind of life-changing experience. (Frankly, you may just want to turn the sound off — it’s that annoying.) It’s really not that big a deal to hit steel at 750 yards with a quality AR-15, chambered in .223 Rem, shooting Sierra 77 grain MatchKings.

Texas .223 Rem Drone Video 1000 Yards Gorilla Ammo

Hitting Steel at 1122 Yards with 2540 FPS Ammo Can Be Challenging
The 1122-yard hits are a bit more impressive. Gorilla Ammo lists a relatively sedate 2540 fps Muzzle Velocity for its .223 Rem 77gr SMK ammunition. According to JBM Ballistics, at 1125 yards, that 2540 fps load has 68.3 MOA of drop from a 100-yard zero (firing at sea level and 80° F ambient). Morever the bullet goes trans-sonic around 750 yards (losing stability) and is traveling just 933 fps at impact. And the wind’s the killer — at 1125 yards, with this bullet/load, a mere 2 mph, full-value wind change can move the Point of Impact over three feet!

Trigger Tech: Trigger Options for AR-Platform Rifles

AR15 Timney drop-in trigger two-stage 2-stage single stage

AR-platform rifles are fun and versatile, but the standard, mil-spec triggers leave much to be desired. They tend to be gritty, with creep and heavy pull weight. One of the easiest, most effective AR upgrades is a trigger group swap. An improved fire control group makes a huge difference. There are many aftermarket trigger options for the AR platform rifles. Choose single-stage or two-stage, either standard trigger assembly or unitized “drop-in” trigger, such as those made by Timney or Triggertech.

AR15 Timney drop-in trigger two-stage 2-stage single stageTwo-Stage vs. Single-Stage Triggers
Two-stage triggers have two separate movements. The first stage offers a light, spring-loaded pressure that works against the shooter’s pull until stopping at the second stage – this is called “take-up”. If there is no spring pressure, it is known as “slack”. Should the shooter continue to pull the trigger once he’s arrived at the second stage, the mechanism will operate like a single-stage trigger from there until engaging the sear and firing the gun. Some shooters prefer a two-stage trigger because it allows a mental preparation (first stage) before the final decision to “break the shot”.

Single-stage triggers feature no take-up or slack, as they begin engaging the sear as soon as the shooter begins pulling the trigger. Some competitive shooters prefer the two-stage trigger because of the feedback it provides during its first stage, while other shooters, including those using their rifle in tactical scenarios, may want the surety of a single-stage trigger, ready to engage and fire once their finger is inside the trigger guard. Regardless of preference, a good trigger will feature minimal creep and should be free of grittiness, providing a smooth, even break.

AR15 Timney drop-in trigger two-stage 2-stage single stage

Drop-In Trigger Assembly vs. Standard Trigger Group
Once you decide between a single-stage or two-stage trigger, you can choose between standard and drop-in trigger groups. Standard trigger groups feature all the fire control group parts separated, and need to be pieced together and installed much like a mil-spec trigger, while drop-in trigger are pre-assembled and contained within a casing that simply drops in to the receiver and accepts the pins, hence the name.

After-Market Trigger Comparison

Some shooters prefer drop-in triggers due to the ease of installation, while others opt for standard groups so they can access the components individually for cleaning adjustment or replacement. If one piece of a drop-in trigger fails, you’ll need to either replace the entire unit or send it to the manufacturer for repair, whereas you may be able to simply replace the broken component of a standard trigger without needing a whole new trigger set.

Trigger Terminology — “Creep”, “Stacking”, “Overtravel”
“Creep” or “travel” is the distance the trigger moves between the end of take-up and when the trigger breaks to fire the fun. Too much creep can affect accuracy, but no creep can be unsafe, as the shooter may not be prepared to fire. “Stacking” occurs when the trigger weight actually increases during travel — this shouldn’t happen. Lastly, “overtravel” is the distance the trigger continues moving back after the gun fires.

Zediker Book Helps with Build-You-Own AR-15 Projects

AR15 Varmint rifle AR gunsmithing robert whitley

AR15 construction guideMany of our readers use AR-type rifles for Service Rifle matches, varmint hunting, 3-Gun competition, or defensive use. AR-platform rifles can be configured in a multitude of ways to suit the application. But if you plan to put together your own purpose-built AR rifle, how do you get started?

For AR Do-It-Yourselfers, we suggest reading Glen Zedicker’s book, the Competitive AR-15 Builders Guide. Following on Zedicker’s The Competitive AR15: Ultimate Technical Guide, the Builders Guide provides step-by-step instructions that will help non-professional “home builders” assemble a competitive match or varmint rifle. This book isn’t for everyone — you need some basic gun assembly experience and an aptitude for tools. But the AR-15 Builders’ Guide provides a complete list of the tools you’ll need for the job, and Zedicker outlines all the procedures to build an AR-15 from start to finish.

One of our Forum members who purchased the AR-15 Builders Guide confirms it is a great resource: “Much like any of the books Mr. Zediker puts out this one is well thought-out and is a no nonsense approach to AR building. I can not stress how helpful this book is from beginner to expert level.”

Along with assembly methods, this book covers parts selection and preparation, not just hammers and pins. Creedmoor Sports explains: “Knowing how to get what you want, and be happy with the result, is truly the focus of this book. Doing it yourself gives you a huge advantage. The build will honestly have been done right, and you’ll know it! Little problems will have been fixed, function and performance enhancements will have been made, and the result is you’ll have a custom-grade rifle without paying custom-builder prices.” Other good resources for AR projects is Gunsmithing the AR: The Bench Manual, and the Building Your AR from Scratch DVD.

Zediker Examines Long Range Shooting with AR-Platform Rifles

AR15 ar-15 long range

Looking to shoot an AR-platform rifle out past 500 yards? Then you should read two articles by AR guru Glen Zediker. Author of The New Competitive AR-15 and The Competitive AR15 Builders Guide, Zediker is an expert when it comes to AR-platform rifles. Glen believes ARs have excellent long-range capability, provided they are built to high standards, with good barrels.

Glen says: “a properly configured AR-15 is easily capable of good performance at 500+ yards. Good performance means it can hit a 1-foot-square target all the time. Competitive shooters can cut that standard in nearly half (the X-Ring on an MR1 600-yard NRA High Power Rifle target is 6 inches, and high X-counts are commonplace among more skilled shooters).”

Published in the Cheaper than Dirt Shooter’s Log, Zediker’s articles first cover the history of the AR-15, and then explain how AR-platform accuracy can be optimized. Part One reviews the AR’s development as an accurate firearm, tracing its evolution from a Vietnam-era combat weapon to what is now a favored target rifle of High Power competitors. READ PART ONE.

Long Range AR AR-15 Glen Zediker Cheaper than dirt

Part Two discusses the specifics that make an AR accurate at 500 yards and beyond. Zediker talks about barrel configuration (profile and twist rate), bullet selection, floating handguards, and proper mounting of optics or iron sights. READ PART TWO.

Long Rang AR AR-15 Glen Zediker Cheaper than dirt

Here are some highlights from Long-Range AR-15 Part TWO:

Barrel Twist Rate
To stabilize anything longer than a 68- or 69-grain bullet, the barrel twist rate must be — at minimum– 1-in-8. Twist rates reflect how far the bullet travels along the lands or rifling to make one complete revolution. So, 1-in-8 (or 1-8, 1:8) means “one turn in eight inches.” I think it’s better to go a little faster in twist. There is nothing wrong with a 1:7 twist. The 90-grain bullets require a 1:6.5, and that is getting on the quick side. If you want to shoot Sierra 77s or equivalent, and certainly anything longer, 1:8 is necessary. By the way, it is bullet length, not weight, which constitutes the necessary twist rate to launch a stable bullet.

Optics Mounting
Correct optical sight positioning can be a challenge. With a flattop upper, I need a good inch additional forward extension at the muzzle side of the upper for the sight mount bases to avoid holding my head “back” to get the optimal view through the scope. A longer rail piece is necessary for my builds as a result.

Buttstock Length and Adjustment
An adjustable buttstock is valuable, and even more valuable if it’s well-designed. Mostly, a standard stock is too short, and the cheek area sits too low. Adding length helps a lot by itself. There are assemblies that replace the standard buttplate to allow for length and, usually, height and rotation adjustments for the buttpad. An elevation-adjustable cheekpiece is a big help to attain a solid position.

AR15 3D Animation — See How an AR Really Works

ar-15 AR15 3D animation video youtube cutaway 5.56 AR .233 Rem

Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.

This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:

Sunday Gunday: AR-Platform Rifles for PRS Gas Gun Series

AR15 AR-15 Gas Gun Series

ARs in PRS? Yes PRS has a “Gas Gun” division. And frankly, shooting a PRS match is one of the most fun and challenging things you can do with your Black Rifle (Beto O’Rourke notwithstanding). Since the early days of the PRS, Gas Gun shooters have wanted to play. Recognizing the interest among semi-auto shooters, the PRS now offers a Gas Gun Series for semi-auto rifles such as AR15s and AR10s. The Gas Gun Series started in 2017, and has quickly become quite popular.

PRS Gas Gun Series Rules

For the new PRS “Gasser” Competition, the PRS developed rules on gun types, scoring, match timing, penalties, safety and other key topics. CLICK HERE for Full PRS Gas Gun Series Rules.

Open Division: Open Division rifles will not exceed a caliber of .30 or a velocity of 3,200fps. A match DQ will result any rounds over the speed limit of 3,200 fps (+/- 32 fps for environmental factors and equipment discrepancies). Match Officials may request at any point during a match that a competitor fire their rifle through chronograph. If the bullet exceeds the 3,200 fps speed limit, the shooter will receive an automatic match DQ. [“For Ammo in Open Class, 6mm and 6.5mm Creedmoor are popular.” — John Parker, SSUSA]

Tactical Division: Tactical Division: Intended to allow competitors the opportunity tocompete using traditional military and law enforcement caliber. This promotesActive Duty military and law enforcement competitors use of their Service and Department issued rifles. Tactical Light Division rifles are restricted to 5.56 NATO/.223 Remington and 7.62 NATO/.308 Winchester calibers only. .223 Bullet weight cannot exceed 77 grains and muzzle velocity cannot exceed 3,000 fps, .308 bullet weight cannot exceed 178 grains and muzzle velocity cannot exceed 2,800 fps. No modified wildcat rounds permitted to shoot in the Tactical Divisions. Tactical Division shooters will shoot the exact same COF as Open Division shooters. [NOTE: This division now replaces the previous Tactical Light and Tactical Heavy divisions.]

Scoring and Penalties
The Gas Gun Series utilizes a time plus penalty based scoring system for all match scoring. This means your score is your total combined time on all stages plus any penalties you may have accrued.

Stage Course of Fire and Targets
No more than 50% of the stages at a match can utilize an unlimited round count. At least 25% of the targets in Gas Gun Series match must be 2 MOA or smaller. Maximum distance is 800 yards.

The preferred rifle color choice at the first PRS “Gasser” Match was definitely black…
PRS Gas Gun

Gas Gun Match Loads — Short Range vs. Long Range
“The .223/5.56 [Tactical Light] guns had some lag time waiting on shot impacts. I believe the long-term solution may be to find a light and fast load for closer stages for near-instant reaction time and use a heavy load for the long shots to see splash and get the target to move a little more.” — Sean Murphy, Nightforce

Gear Options for PRS Gas Guns
There are many buttstock options for ARs. For the PRS game, we like the Magpul PRS stock. This features a quick-adjustable cheek-piece and butt-plate — allowing you to easily adapt head position and LOP for your discipline of the day. (You may want a different LOP for prone shooting vs. bench shooting). The Magpul stock works well in a rear bag.

Colt AR AR15 match rifle upper lower kit discount CDNN

We recommend something like the Blackhawk grip which is more comfortable than the typical grips supplied by most black rifle makers. Up front, you’ll want a handguard with adaptability. Shown is a handguard with Picatinny rails on top and on both sides, affording lots of options. We might move one of the rails to the bottom, however, so it could be used for a bipod mount.

PRS with a Gas Gun — Gavin Gear’s Experience

Thinking of trying out the Precision Rifle Series, starting off with a gas gun? Well Gavin Gear of UltimateReloader.com did just that, competing in his first-ever PRS match up in Washington State. With its timed stages (some just 90 seconds long), Gavin learned that PRS is about speed as well as accuracy. As a PRS newbie, Gavin found the competition fun but challenging. Gavin’s account of his experiences, set forth in two articles with accompanying videos, will help other novice PRS competitors prepare for PRS-type matches and assemble the right equipment.

This video has cool Aerial Drone footage, and in-depth explanation of stages:

READ Full Story of Gavin’s First PRS Match »

Gavin enjoyed his first match: “Overall, the match was more fun and more laid back than I thought it would be. The guys in our squad were all really helpful, and even loaned me gear to try out when they noticed my gear wasn’t right for a particular shooting activity. One such case was when Ken Gustafson (of KYL Gear) offered to loan me one of the bags he had made. Below you can see me shooting off the infamous unstable tippy tank trap with a KYL Gear bag, and I’ll have to say [the bag] was amazing. It helped me lock down my rifle and get on target. What a great feeling!”

Federal District Court Dismisses Suit Against AR-15 Makers

Federal court case dismiss dismissal Primus Smith Wesson Ohio district U.S.

Chalk up a legal victory for the gun industry. The U.S. District Court (Southern District of Ohio) has dismissed, with prejudice, the Primus Group v. Smith & Wesson, et al lawsuit. The decision was delivered October 9, eliminating the plaintiff’s claims against several prominent AR-15 firearms manufacturers, including Smith & Wesson, Remington Arms Company, SIG Sauer, Sturm, Ruger & Company, Colt Manufacturing, and Armalite.

Federal court case dismiss dismissal Primus Smith Wesson Ohio district U.S.“This decision by the federal judge to dismiss with prejudice this frivolous case is pleasing, if not unexpected,” said Lawrence G. Keane, NSSF Senior Vice President of Government Relations and Public Affairs and General Counsel. “These are lawful and federally-regulated AR-15 modern sporting rifle manufacturers that make semiautomatic rifles for lawful purposes. The judge was absolutely correct to assert that the proper venue to establish public firearms policy is through the legislature and not the courts.”

Primus Group, LLC, is a small entity in Columbus, Ohio with a vague business model. The limited liability company filed suit after the tragic murders in El Paso and Dayton, Ohio. They claimed racketeering, intentional misrepresentation claims, and “a clear and present danger” of all American lives due to “assault weapons”. The modern sporting rifles manufactured and sold by the companies named as defendants are semi-automatic rifles, meaning one round is fired for each trigger pull.

The court found the plaintiffs had no standing to bring the case against the defendants. This decision rightfully asserts that those who purposefully and criminally misuse firearms are the ones who are responsible for those crimes. It further affirms that activist lawsuits to prompt judicial action are not the proper avenue to establish policy.

Walmart Halts Sales of .223 Rem and Handgun Ammunition

Walmart ammo ammunition ban stop selling AR15 rifle shotgun

Walmart is yielding to anti-gun forces one step at a time. First the national retail chain stopped selling handguns in 1993. Next in 2015, Walmart stopped selling “black rifles” — AR-15 platform firearms. Then in 2018 Walmart raised the age for gun purchases from 18 to 21. And the latest restrictions involve ammunition. Walmart announced it would not longer sell ANY pistol ammunition. And Walmart now won’t sell .223 Rem (5.56×45) ammunition commonly used in ARs and “modern sporting rifles”. What comes next? If a criminal uses a shotgun in a multiple-death incident, will Walmart stop selling shotguns?

1993 — Walmart halts sales of all handguns.
2015 — Walmart halts sales of AR-15 type rifles.
2018 — Walmart raises minimum age for firearm purchase from 18 to 21 years.
2019 — Walmart halts sales of all pistol ammunition.
2019 — Walmart halts sales of all .223 Rem (5.56×45) ammunition.

Walmart Expands Its Anti-Gun Agenda

Article based on Report by Midsouth Shooters Blog

Walmart has been steadily rolling back its support of the Second Amendment since 1993 when it stopped the sale of all handguns in every state except Alaska. Then, in 2015 it ended the sale of AR-15 style MSR rifles, and any toy or airgun resembling any “military-style rifle used in mass shootings”. Last year, Walmart raised the minimum age for gun purchases from 18 to 21, two weeks after the Parkland, Florida school shooting. And Walmart rolled out another set of restrictions after the recent shooting at a Walmart Super Center in El Paso, Texas.

“Walmart may not sell the ammo you need, and more companies beholden to the pressure of the vocal minority may follow suit. Effectively, Walmart has been bullied into kowtowing to the social justice warriors, and woke-ninjas in the vocal minority.” — Midsouth Blog

In a memo to employees, Walmart CEO, Doug McMillon, stated: “After selling through our current inventory commitments, we will discontinue sales of short-barrel rifle ammunition such as the .223 caliber and 5.56 caliber that, while commonly used in some hunting rifles, can also be used in large capacity clips on military-style weapons.”

Walmart has also stated that it will no longer sell handgun ammo. McMillon previously said Walmart was responsible for 2% of firearm sales in the U.S. and 20% of ammunition sales. Walmart expects its share of ammunition sales to drop to between 6% and 9% as a result of the newly-announced changes. The company will continue to sell shotguns and rifles [But for how long? — Editor].

“In a complex situation lacking a simple solution, we are trying to take constructive steps to reduce the risk that events like these will happen again,” McMillon said in a memo. “The status quo is unacceptable.” In this 2015 video, McMillon explained the decision to stop selling AR-platform rifles.

Walmart ammo ammunition ban stop selling AR15 rifle shotgun

Changes to Walmart Gun Carry Policies
Another rider on the new Walmart policy affects customers who open-carry in their stores. If shoppers openly carry guns into Walmart stores going forward, store managers may ask the shopper to leave and safely secure their gun in their vehicle before returning to the store. “The policies will vary by location, however, and shoppers who are openly carrying guns may not always be asked to leave the store,” a Walmart spokesman said.

“As long as a Hornady is at Hornady, we will never sell direct to Walmart. They are no friend of the industry.” — Jason Hornady, 2007

Walmart CEO Calls for More Gun Control
“We encourage our nation’s leaders to move forward and strengthen background checks and to remove weapons from those who have been determined to pose an imminent danger,” McMillon said. “We do not sell military-style rifles, and we believe the re-authorization of the Assault Weapons Ban should be debated to determine its effectiveness.”

Commentary from Midsouth Shooters
Walmart may not sell the ammo you need, and more companies beholden to the pressure of the vocal minority may follow suit. Midsouth will continue to sell the ammunition and reloading supplies you need, regardless. Our Second Amendment right is a sacred right, and for you to protect your family with the tools available, you need access to fairly priced ammunition and firearms.

Midsouth Shooters supply

Midsouth Shooters was founded on the tenants of honesty, family, and fairness, rooted in American and God. For a company, or organization, to be swayed by knee-jerk reactions sets a precedent of allowing the mob to dictate overreaching policies which put many in harms way. Effectively, Walmart has been bullied into kowtowing to the social justice warriors, and woke-ninjas in the vocal minority.”

Scary Stuff — .300 Blackout Fired in a .223 Rem Barrel

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56
Photos and Facebook post by Tactical Rifle Shooters

Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!

This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”

For those who MUST have a .300 Blackout, here are some things you can do:

1. Use different colored magazines for .300 Blackout vs. .223 Rem.
2. Fit all your uppers with caliber-labeled ejection port covers.
3. Mark .223 Rem upper handguards with the caliber in bright paint.
4. Mark all .300 BLK Rounds with heavy black marker.

Comments by Folks Who Viewed these .300 Blackout Disaster Photos:

“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago

“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch

“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood

“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres

“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams

If the bullet exceeds the 3,200 fps speed limit, the shooter will receive an automatic match DQ.

Tactical Light Division: Intended to allow competitors the opportunity tocompete using traditional military and law enforcement caliber. This promotes Active Duty military and law enforcement competitors use of their Service and Department-issued rifles. Tactical Light Division rifles are restricted to 5.56 NATO/.223 Remington calibers only. Bullet weight cannot exceed 77 grains and muzzle velocity cannot exceed 3,000 fps.

Shooting Sports USA interviewed PRS President Shawn Wiseman:

SSUSA: What will be the format of the PRS Gas Gun Series matches?
Wiseman: The matches will be a two-day format with 8 to 10 stages per day. There are three Divisions: Tactical Light for 5.56x45mm NATO/.223 Rem. rifles; Tactical Heavy for 7.62x51mm NATO/.308 Win.; and Open for everything else up to .30 cal. The maximum distance will be 800 yards.

SSUSA: What guns do you expect to be popular?
Wiseman: In the Open Division, I expect to see a lot of 6.5 Creedmoors for two main reasons; it’s an inherently accurate cartridge and Hornady makes great ammo for the folks that aren’t into reloading. I think the Tactical Light Division will probably be the most popular. It is hard to say specifically what rifles will be the most popular but there are a few AR companies that are known for the accuracy. Armalite, GA Precision, LaRue and Seekins will all be very popular rifles in this Series. I think we will continue to see high-end optics with 5X to 6X zoom range on the rifles. Bushnell, Kahles, Leupold, Nightforce and Vortex will continue to be the most popular.
