Thanksgiving is just two weeks away. We know many readers will soon be traveling to spend the holiday with family members. If you will be flying with firearms this November, you should read this article. You need to familiarize yourself with current Federal Regulations on gun transport before you get anywhere near an airport. Thankfully, the Transportation Security Administration (TSA) has a web page that states the important requirements for airline passengers traveling with firearms* and/or ammunition.

You’ll want to visit the TSA Firearms and Ammunition webpage, and read it carefully. In addition, before your trip, check the regulations of the airline(s) with which you will fly. Some airlines have special requirements, such as weight restrictions.

Here are the TSA’s key guidelines for travel with firearms:

More Airline Travel Tips from Tom McHale
Tom McHale has written an excellent article for the Beretta Blog, Ten Things You Need to Know about Flying with Guns. We suggest you visit the Beretta Blog to read this informative story. Here are two of Tom McHale’s Travel Tips:

Weigh your gun case and ammunition
Most airlines will allow up to 11 pounds of ammunition. And, like any luggage, you will be charged more for any baggage weighing more than 50 pounds. This sounds like a lot, but when traveling to the Crimson Trace Midnight 3 Gun competition last year, my case with shotgun, rifle, pistol and ammunition tipped the scale past the 50 pound mark.

Pack ammo in the same locking case
This is another area that’s misunderstood and full of internet myth. Your ammo just needs to be stored in some type of safe container and not loose. Technically, you can keep ammunition in magazines, but I wouldn’t recommend it. It meets the letter of the law storage requirement, but too many airline and TSA agents will give you grief. Use a plastic ammo box or original cardboard packaging and you’ll be fine carrying that in the same lockable case as your gun.

*SEE United States Code, Title 18, Part 1, Chapter 44. A “firearm” is defined as: any weapon (including a starter gun) which will, or is designed to, or may readily be converted to expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; and any destructive device. As defined by 49 CFR 1540.5 a loaded firearm has a live round of ammunition, or any component thereof, in the chamber or cylinder or in a magazine inserted in the firearm.

.308 Win vs. 6BR vs. .223 Rem — Recoil Energy Comparison Chart

6mmBR NormaMany visitors to the site ask us, “I’ve got a .223 and .308. What will a 6mmBR Norma (6BR) give me that I’m not getting already?” Well first you will probably average consistently smaller groups than your current .223 or .308 rifle (assuming the 6BR has a quality barrel and trigger). A good .308 Winchester can be superbly accurate, no question about that, but the lesser recoil of the 6BR works in the shooter’s favor over a long string of fire. Even with a Rem 700 or Savage action factory action, a 6BR with a benchrest stock, premium barrel, and a high-quality chambering job should deliver 5-shot groups in the high twos to mid-threes, provided you do your job. We have one 6BR rifle that shoots Lapua factory-loaded 6BR ammunition in the low twos and high ones. That’s exceptional, we admit, but it still shows how the 6BR is an inherently accurate cartridge, even with factory loads.

Compared to a .223, the 6BR offers a much better selection of high-BC projectiles, and will deliver considerably more power on the target. So it’s a better choice for hunters and 600-yard benchrest shooters. Compared to the .308 Win shooting 168gr MatchKings, a 6BR shooting 105-107gr bullets offers better ballistics all the way out to 1000 yards. Plus, for most people, the 6BR is just easier to shoot than a .308 Win. Recoil is less than half of the .308 Win cartridge. Both the .308 and 6BR chamberings offer good barrel life, but the 6BR uses 15-18 grains less powder, saving you money. On the other hand the .308 Win is the designated cartridge for F-TR and Palma shooting, so it may be a more versatile chambering for Long-Range competition. So which would we choose between the 6BR and the .308? Actually we think you should have both. The 6BR is a favorite cartridge out to 500 yards, and we like the .308 Win for F-TR. The .308 Win has shown outstanding accuracy, as displayed last week at the NRA F-class Nationals in Arizona.

How to Understand Headspace — What You Need to Know

Ultimate Reloader Brownells headspacing go gage gauge barrel gunsmithing
This illustration shows headspace measurement for the popular .308 Winchester cartridge, which headspaces on the shoulder. Image copyright 2015 Ultimate Reloader.

In this Brownells Tech Tip Video, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.

Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge. If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)

Forster Headspace diagram belted magnum rimfire

Problems Caused by Too Much Headspace
Excessive headspace issues can include: light primer strikes, failure to fire, bulged/blown cases, case separations, split shoulders, or unseated primers after firing. Case ruptures caused by excessive headspace can lead to catastrophic failures causing serious injury. That is why headspace is such an important measurement.

Problems Cause by Too Little Headspace
Insufficent (or excessively tight) headspace can prevent the firearm from going into battery, resulting in failure to fire or deformation of the cartridge case. Various feeding and functioning problems can be caused by cases with too little headspace, even if a round can be chambered (with effort).

Go gauge gage NOGO no-go field gaugesHeadspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)

You need to understand Headspace Gauges and how to use them. There are “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest. Brownells explains: “The GO gauge corresponds to the SAAMI minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life [.]”

Replace Gun Safe Batteries Every Year — Don’t Get Locked Out!

If the battery on your safe’s electronic lock is
more than a year old, or if it is not giving you the
right voltage, replace it today!

safe battery gunsafe sargent greenleaf

Gunsafe safe keypad control battery batteriesThis time of year, many readers are putting their guns away in a safe for the winter. It’s easy to just tuck the guns away and forget about them. But there’s something you should do before you shut the safe door.

If you have a safe with an electronic keypad, you should replace the battery every year as a precautionary measure. Trust us, you don’t want to come back in a few months and find that the keypad memory is kaput, and you’re locked out. That can lead to an expensive locksmith visit.

Low Voltage Battery? You May Be Locked Out…
Here’s a true story. I have one safe with a Sargent & Greenleaf (S&G) keypad. A couple years back, in early December, I went to get into the safe. I punched in the correct combination, but all I got was a rapid “beep, beep, beep, beep” after I finished the last combination entry. I tried again to ensure I entered the combination correctly (I did). But again, the locking system responded with multiple rapid beeps indicating something was wrong. And the safe would not open. Now I was worried….

I popped out the battery holder (which slides in from the bottom of the keypad housing on the door). I removed the battery and tested it with a volt-meter. The 12-month-old Duracell 9-volt battery only registered 6.1 volts.

Low voltage was the problem. I went down to the store and got a couple new 9V batteries. I tested the new batteries and both measured 9.4 volts output. I slipped one of the new 9V batteries into the keypad housing, punched in the combination and everything worked OK again. Eureka.

Most electronic locks for safes WILL “remember” the combination for a period of time even when the battery is low (and the keypad’s “brain” should retain the combination when you remove the battery for replacement). However, a dead battery, or extended periods of low voltage can give you problems. Don’t rely on wishful thinking…

Firearms Sales and Gift Transfers — What You Need to Know

Firearms straw sale transfer buy sell

Are you planning to purchase or sell a gun? Or perhaps you want to give one to a family member. Maybe you want to transfer a gun to a friend out of state. These are all situations that demand you understand the law before you buy, sell, or transfer a gun. Thankfully the NRA Blog has a series of helpful articles that can guide you through firearms transfers and transactions.

Do note that laws on private transfers vary from state to state. Also, some of these articles are a few years old. Laws do change, typically becoming more restrictive. You should carefully review current laws in your state before buying/selling any firearm. For a summary of state gun laws, we recommend Legal Heat’s 50 State Guide to Firearms Laws and Regulations reference book.

Here are five articles providing key facts you need to know.

Ten Tips for Reloading Ammo with Progressive Presses

6.5 Guys Progressive Press video Gavin Gear Ultimate Reloader

Progressive reloading presses offer shooters speed and efficiency in producing custom-tailored rifle and pistol ammunition. However, there is a wide choice of Progressive Presses and a bewildering array of options to consider. In this video, the 6.5 Guys and UltimateReloader.com’s Gavin Gear provide an overview of the leading Progressive Presses on the market along with key considerations for precision rifle shooters. If you are considering getting a Progessive for rifle ammo reloading, you should watch this informative, 25-minute video.

10 Tips for Reloading Rifle Ammo on a Progressive Press:

1. Make sure the brass is very clean. Don’t mix old range pick-up brass with newer brass.

2. Apply a thin, spray lube to all cases before the sizing/loading cycle.

3. Consider priming your brass separately (with a hand or bench tool) before the operation. Then inspect the primers before loading powder and bullets.

4. Always wear eye protection when loading with the Progressive, particularly if you are priming cases.

5. With masking tape, mark the powder measure/dropper with the powder type and cartridge charge weight. Check the charge mass multiple times (see below).

6. Cycle a few cases, sizing and adding powder but NOT seating bullets. Weigh the powder charges to ensure the powder measure is dispensing the correct charge. Sometimes this will change a couple tenths as it “settles down” after the first few charges.

7. Check the brass for shoulder bump and bullet seating depth carefully for the first few rounds, then check again periodically.

8. Try to maintain a steady pace and operate the handle the same way every time.

9. Visually inspect the powder charge in each case (before bullet seating), and use a lock-out die if your Progressive Press has enough stations.

10. Never, ever mix pistol and rifle powders! If you have previously loaded pistol ammo with your Progressive, make sure ALL the powder (every flake and kernel) is removed from all parts of the powder-dropping system before you add rifle powder.

Wow Factor: Muzzle Brake Blast Patterns Revealed

Precision Rifle Blog Muzzle Brake Test Blast Powder

A while back, the Precision Rifle Blog conducted a fascinating study of Muzzle Brakes. PRB figured out a way to show the actual “blast pattern” of gasses ejecting from the ports of muzzle brakes. The result was a fascinating (and eye-catching) series of images revealing the distinctive gas outflows of 20+ different types of muzzle brakes. If you are considering buying and installing a muzzle brake on your rifle, you should definitely review this important PRB Muzzle Brake Test.

GO to PRB Muzzle Brake Blast Pattern TEST PAGE »

For a prone shooter, particularly on dusty, dirty or sandy ground, muzzle blast is a major bummer. Muzzle blast can be very disturbing — not just for the trigger-puller but for persons on either side of the gun as well. Some muzzle brakes send a huge shockwave back towards the shooter, and others send blast towards the ground, kicking dirt and debris into the prone shooter’s face. If there was a way to illustrate those factors — shockwave and debris — that might help shooters select one brake design over another.

Precision Rifle Blog Muzzle Brake Test Blast Powder

Cal Zant at PrecisionRifleBlog.com applied a unique blend of creativity and resourcefulness to try to answer that question for 20+ muzzle brakes. Using high-speed photography and household products, he captured the blast pattern of 20+ different brake designs for easy side-by-side comparison. Can you figure out how Cal managed to show muzzle brake blasts so clearly? His “hi-viz” solution, revealed in the article, is very clever.

Polish Inside of Seating Stems to Avoid Ring Marks on Bullets

Seating Stem Reloading Tip Sierra Bullet .223 Remington compressed loads

Here’s a helpful hint for hand-loaders from Sierra Bullets. While this article focuses on Sierra’s new Tipped Match-King bullets, the recommended solutions apply to other bullet types as well. The article explains how sharp edges on a seating stem can cause a ring to be pressed into the bullet jacket — especially with compressed loads that resist downward bullet movement. Here Sierra technician Rich Machholz diagnoses the problem and provides a solution.

Seating Stem Reloading Tip Sierra Bullet .223 Remington compressed loads

Solutions for Ring Marks Caused by Seating Stems

by Sierra Bullets Ballistic Technician Rich Machholz
Now that the new Tipped MatchKing® (TMK) bullets are being shipped and shooters are putting them to use I have received several calls regarding marking on the bullet ogive from the seating stem.

The cause can be traced to one of several things. In the .223 and especially with the long, 77 grain TMK seated at 2.250” or even 2.260” most loads of Varget® and Reloder® 15 are compressed loads, sometimes heavily compressed. This puts a great deal of pressure on the bullet through the seating stem. The result of all this pressure is a mark of varying depth and appearance on the ogive of the bullet. [Editor: We have seen this issue with a variety of other bullet types/shapes as well, including non-tipped VLDs. The solution is profiling the internal cone of the seating stem to match your bullet shape.]

Some older seating stems might even bear against the tip of the bullet which can make a slight bulge in the jacket just below the junction of the resin tip and the copper jacket in a compressed load. If this is the case there is not a ready fix other than calling the die manufacturer and requesting a new deeper seating stem.

Polish Your Seating Stem to Remove Sharp Internal Edges
If the seating stem is of proper depth the culprit most generally is a thin sharp edge on the inside taper of the seating stem. This is an easy fix that can be accomplished by chucking a spare 77 grain bullet in your drill, coating it with valve grinding compound or even rubbing compound or in a pinch even tooth paste.* Remove the seating stem assembly from the seating die. Turn the drill on and put the seating stem recess over the spinning bullet with the polishing compound to break or smooth the sharp edge that is making the offending mark. This might take more than one application to get the proper polish depending upon what you use, but the more you polish the better the blend of angles which will [ensure the stem matches the bullet contours, not leaving a sharp ring].

If the above is a little more than you care to tackle you might try very fine emery cloth twisted to a point that can be inserted into the mouth to the seating stem and rotated to polish the inside to eliminate any sharp edges that might be present.

Load Advice for 77gr TMKs in the .223 Rem
And last but certainly not least. Actually, even though we don’t say you need additional data for the TMKs, remember you are dealing with heavily-compressed loads in some cases because of the additional bullet length. Due to the additional length of these new bullets and in the interest of gaining some room in the case you might consider trying a slightly faster extruded powder like BenchMark or the 4895s or an even more dense powder like the spherical H335®, CFE223 or TAC. The extra room will allow for trouble free bullet seating also.

Primer Problems? Check Your Primer Seating Tool

Priming Tool APS CCI magnum Primers Lee RCBS Priming

From time to time, we all encounter a primer that doesn’t go off. It’s normal to attribute the problem to a bad primer. But sometimes there are other explanations. George S., one of our Forum members, experienced a couple failures to fire, but he learned that the issue was his priming TOOL, not his primers. Here’s what George told us. There’s a lesson to be learned:

“I had issues with CCI 450s when I had my first 6BR barreled. I had probably three or four out of 20 rounds that failed to fire. the primers were dented but didn’t fire. I called CCI since I had bought a case of them. The tech was decent enough but had the audacity to tell me I was not seating the primers all the way in the pocket. I proceeded to let him know I had been reloading longer than he had been alive and I knew how to seat a primer.

Turns out that I did and I didn’t! I was using the RCBS primer tool I had used for years and the primers felt just fine to me. I finally decided to check the tool and since I had a new one I took the seating pins out and measured them. The seating pin on the tool I had been using for years was shorter by a few thousandths! I then used the pin from the new primer tool and darned if the primers that didn’t seat down to the bottom of the cup.

I switched to a K&M primer tool for seating the CCI primers and have not had a problem since. It was the combination of harder cup and lack of proper seating. I did call the CCI tech back and apologized for being an idiot.”

Another Forum member witnessed a problem cause by misuse of a priming tool: “I did … see a failure to fire on a Rem 9 1/2 primer only a week ago. That was in the new Rem muzzleloader that uses a primed case to ignite the pellets. After watching the muzzleloader’s owner seat his primers, I believe that it was operator error not the primer. He was seating the primer and then squeezing the priming tool so hard that his hands hurt after a few. We got that corrected.”

Powder Mistake Results in Dangerous Revolver Kaboom

Revolver kaboom wheelgun explosion mistake reloading powder safety

This shocking Revolver Kaboom resulted from “user error”. Our friends at Midsouth Shooters provided this cautionary tale, noting that you must ALWAYS be careful when hand-loading any ammo. Check your loads and don’t have multiple powder containers in your reloading area.

Revolver kaboom wheelgun explosion mistake reloading powder safety

“Ever wonder what happens when you don’t pay attention to detail? A word of advice from the reloader who brought this in — always double-check the load data.

Thankfully, the shooter was unharmed in the explosion. A live round we recovered from the remaining portions of the cylinder contained 12.8 grains of powder. The shooter had multiple powders on his bench and was unable to recall which one had been used while loading.” — Midsouth Shooters

Revolver kaboom wheelgun explosion mistake reloading powder safety

How to Avoid Kabooms

1. Never have more than one powder container open on your reloading bench at the same time — when you are finished with a powder, seal the bottle and put it away.

2. If there is already powder sitting in your dispenser, and you’re not 100% sure what it is — throw it out. We suggest, whenever you fill a powder hopper, put a piece of paper in the powder hopper with the name of the powder and the date.

3. When loading a new cartridge or when using a new powder, get load data from more than one source. Always load conservatively to start!

4. Always double-check your Load Data before starting the loading process.

5. In short handgun cases, bullet seating depth can make a BIG difference in pressure levels. Be sure to check your Cartridge OAL.

Krieger Cut-Rifled Barrel-Making — Start to Finish on Video

Krieger Barrels Cut Rifling Cut-Rifled Barreling

How Krieger Builds Barrels

This video shows the process of cut-rifled barrel-making by Krieger Barrels, one of the world’s best barrel manufacturers. Krieger cut-rifled barrels have set numerous world records and are favored by many top shooters. The video show the huge, complex machines used — bore-drilling equipment and hydraulic riflers. You can also see how barrels are contoured, polished, and inspected.

For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

Pratt & Whitney Cut rifling hydraulic machine

“At the start of World War Two, Pratt & Whitney developed a new, ‘B’ series of hydraulically-powered rifling machines, which were in fact two machines on the same bed. They weighed in at three tons and required the concrete floors now generally seen in workshops by this time. Very few of these hydraulic machines subsequently became available on the surplus market and now it is these machines which are sought after and used by barrel makers like John Krieger and ‘Boots’ Obermeyer. In fact, there are probably less of the ‘B’ series hydraulic riflers around today than of the older ‘Sine Bar’ universal riflers.” — Geoffrey Kolbe, Border Barrels.

The 2023 F-Class National Championships commences October 29th at the Ben Avery Range outside Phoenix, Arizona. With economic inflation and the high price of gas in particular we know some F-Class shooters couldn’t make it to Nationals this year. For them, and other folks who are getting started in the sport, here are some special targets that let you train at your home range, even if it does not have target bays at 600 and 1000 yards. These special 300-yard target centers let you duplicate the exact MOA size of the official F-Class targets, but at closer range.

Here is the sleek, carbon-stocked .308 Win rifle Bryan Litz used to win both the 2015 Mid-Range AND
Long-Range F-TR Championship at the Ben Avery Range in Phoenix, Arizona.

These reduced-size target centers were created by Forum member SleepyGator, an F-Class competitor who needed practice targets he could use at 300 yards. There is an official reduced-distanced standard for 300-yard F-Class matches. This utilizes the NRA No. MR-63FC – F-Class Target Center which is pasted over the MR-63 target. It provides a 1.42″ X-Ring, 2.85″ 10-Ring, and 5.85″ Nine-Ring. (The dimensions of F-Class targets are found in the NRA High Power Rules, Sec. 22, part 4, page 70-71 — see sample below.)

To duplicate the 300-yard target, SleepyGator has prepared a printable version of the MR-63FC Target Center, along with a pair of training targets with two bulls and five bulls. The two-bull and five-bull targets mirror the scoring rings on the MR-63FC, but they display only the innermost three rings and two rings respectively. All three targets are Adobe Acrobat (PDF) files that can be easily printed. You may need to adjust the scale (sizing) on your printer to get the dimensions exactly correct. As noted above, when printed, the 10-Ring on all three targets should measure 2.85″. This should provide some handy practice targets you can use between matches. Thanks to SleepyGator for providing these targets. You can download all three as a .Zip archive. After downloading the .Zip file, just click on the .Zip archive to extract the individual targets.
