Gone in SIX Seconds — The Brutal Truth of Short Barrel Life

Stopwatch barrel life

This thought-provoking article has been one of the most popular Daily Bulletin features in recent years. We are republishing this story today for readers who may have missed it the first time around…

Here’s a little known fact that may startle most readers, even experienced gunsmiths: your barrel wears out in a matter of seconds. The useful life of a typical match barrel, in terms of actual bullet-in-barrel time, is only a few seconds. How can that be, you ask? Well you need to look at the actual time that bullets spend traveling through the bore during the barrel’s useful life. (Hint: it’s not very long).

Bullet-Time-in-Barrel Calculations
If a bullet flies at 3000 fps, it will pass through a 24″ (two-foot) barrel in 1/1500th of a second. If you have a useful barrel life of 3000 rounds, that would translate to just two seconds of actual bullet-in-barrel operating time.

Ah, but it’s not that simple. Your bullet starts at zero velocity and then accelerates as it passes through the bore, so the projectile’s average velocity is not the same as the 3000 fps muzzle velocity. So how long does a centerfire bullet (with 3000 fps MV) typically stay in the bore? The answer is about .002 seconds. This number was calculated by Varmint Al, who is a really smart engineer dude who worked at the Lawrence Livermore Laboratory, a government think tank that develops neutron bombs, fusion reactors and other simple stuff.

On his Barrel Tuner page, Varmint Al figured out that the amount of time a bullet spends in a barrel during firing is under .002 seconds. Al writes: “The approximate time that it takes a 3300 fps muzzle velocity bullet to exit the barrel, assuming a constant acceleration, is 0.0011 seconds. Actual exit times would be longer since the bullet is not under constant acceleration.”

We’ll use the .002 number for our calculations here, knowing that the exact number depends on barrel length and muzzle velocity. But .002 is a good average that errs, if anything, on the side of more barrel operating life rather than less.

So, if a bullet spends .002 seconds in the barrel during each shot, and you get 3000 rounds of accurate barrel life, how much actual firing time does the barrel deliver before it loses accuracy? That’s simple math: 3000 x .002 seconds = 6 seconds.

Stopwatch barrel lifeGone in Six Seconds. Want to Cry Now?
Six seconds. That’s how long your barrel actually functions (in terms of bullet-in-barrel shot time) before it “goes south”. Yes, we know some barrels last longer than 3000 rounds. On the other hand, plenty of .243 Win and 6.5-284 barrels lose accuracy in 1500 rounds or less. If your barrel loses accuracy at the 1500-round mark, then it only worked for three seconds! Of course, if you are shooting a “long-lived” .308 Win that goes 5000 rounds before losing accuracy, then you get a whopping TEN seconds of barrel life. Anyway you look at it, a rifle barrel has very little longevity, when you consider actual firing time.

People already lament the high cost of replacing barrels. Now that you know how short-lived barrels really are, you can complain even louder. Of course our analysis does give you even more of an excuse to buy a nice new Bartlein, Krieger, Shilen etc. barrel for that fine rifle of yours.

David Chipman Withdrawn as Nominee for ATF Director

ATF David Chipman Nomination BATFE Second Amendment Foundation

Recognizing that a confirmation vote was likely to fail, the Biden White House has retracted the nomination of David Chipman to head the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). An aggressive anti-gunner, Chipman has advocated the banning of AR-15s and other popular semi-auto rifles. There were concerns about the handling of his own, issued firearms when he worked for the ATF, and his statements as a paid anti-gun activist were extreme and worrisome. Chipman is currently a paid gun control lobbyist who has worked for Bloomberg’s Everytown, as well as the gun control groups Brady United and Giffords Law Center.

Sen. Mitch McConnell was pleased that the Biden Administration retracted the “terrible nomination of David Chipman”. McConnell noted that it was “absurd that a vocal opponent of Americans’ Constitutional rights was ever picked to run ATF. This is a win for the Second Amendment and law-abiding American citizens.”

Sen. Steve Daines concurred: “I’ve been opposed to David Chipman leading the ATF from the start. He’s an anti-Second Amendment, gun-grabbing radical that should not lead the agency that regulates firearms.”

“The defeat of David Chipman is a victory for all Americans who value the right of self-defense,” said Young Americans for Liberty spokesman Eric Brakey, who added: “Chipman has called for a total ban on private ownership of commonly-owned firearms — like the AR-15[.] President Biden should have never nominated this rabid activist on the payroll of Bloomberg-funded anti-gun groups to lead the ATF in the first place.” And the Second Amendment Foundation’s Alan Gottlieb stated: “This is a great grassroots victory for the Second Amendment.”

Immediately following Chipman’s nomination, Gottlieb said it had the smell of political patronage to the Giffords Law Center gun control lobbying group. He also accurately portrayed the nomination as a declaration of war on gun owners’ rights. “We predicted Joe Biden’s pick would ignite a political firestorm, and it did”, Gottlieb recalled. “The President has been so wrong on so many issues, and the Chipman nomination ranks right up there[.]”

Gottlieb continued: “We’re proud of the grassroots effort to defeat this foolish Biden scheme to put an acknowledged extremist gun ban advocate in charge of ATF[.] This is a major defeat for the billionaire elitists who bankroll the gun prohibition movement.”

The Citizens Committee for the Right to Keep and Bear Arms declared that the withdrawal of anti-gun lobbyist David Chipman’s nomination to head the ATF is “a much-deserved defeat for the gun prohibition lobby and Joe Biden”.

3.2 Million New Gun Owners in 2021 — NSSF Survey Estimates

NSSF new gun owners survey 2021 first half

The National Shooting Sports Foundation (NSSF) recently surveyed firearm retailers nationwide. Based on this survey, the NSSF estimates that over 3.2 million people purchased a firearm for the first time during the first half of 2021. The survey was conducted to learn the buying habits of firearm purchasers during the first six months of 2021. Respondents indicated that 33.2% of customers, or 3,247,351, purchased a firearm for the first time, based on June’s total of nearly 9.8 million background checks for a gun sale.

New Gun Owners Create Massive Demand for Ammo Production
The fact that we have millions of new gun owners is a major cause of the continuing ammo shortage. Consider this — if those 3.2 million new gun owners each purchase just two, 50rd boxes of ammunition, that is 320,000,000 rounds that must be produced to meet the new demand.

“This survey shows that there is a continuing demand signal for firearms from the American public,” said Joe Bartozzi, NSSF President and CEO. “We witnessed each month background check figures associated with a gun sale that are second only to those we saw in last year’s record-breaking totals. These survey results show not only is there a strong and healthy appetite from first-time gun buyers but that there is still room to grow. We are encouraged by the sustained interest in lawful and responsible gun ownership as well as by the manufacturing base which has been challenged to meet this remarkable demand.”

More Women and More Diversity Among Gun Owners
Survey results showed that in the first six months of 2021 there was a significant increase in the percentage of buyers who were female, compared to the period before the Pandemic. In addition, the percentage of gun buyers who were African-American, Hispanic-American, and Asian-American increased significantly. So the ranks of USA gun owners are becoming significantly more diverse, and women are making up an ever-growing share of gun owners.

Training Resources for New Gun Owners
