SafeShoot — Downrange Risk Detection Technology

safeshoot downrange detection sensor

The SafeShoot system is advanced technology that can detect the presence of humans downrange, even in darkness. A sensor attached to a rifle, shotgun, or spotting scope “scans” downrange looking for human profiles. If it “sees” a human in the direction the firearm/spotting scope is pointed, a light in the front sensor unit flashes red. We checked out the system, and the technology really works. This could be very beneficial for anyone shooting on undeveloped land or unsupervised ranges, particularly during hunting season. This SafeShoot technology was developed by experts who have worked with the Israeli military. We think this technology holds much promise.

.224 Valkyrie from Barrett Firearms

.224 Valkyrie Barrett

The SHOT Show TV crew visits Barrett to check out the Barrett Fieldcraft and REC7 rifles chambered in .224 Valkyrie. This video also previews Barrett’s law enforcement and military products. The .224 Valkyrie is a new cartridge from Federal based on a 6.8 SPC necked down to .224 caliber. It offers excellent long-range performance with the new high-BC .22-caliber bullets (such as Sierra 90gr and 95gr SMK), while still fitting and functioning in a standard AR-15 magazine. We’ve shot the .224 Valkyrie and like it. The round looks like a scaled down 6.5 Creedmoor.

Toast in Six Seconds — The Brutal Truth of Short Barrel Life

Stopwatch barrel life

This thought-provoking article is one of the 15 most popular Daily Bulletin features over the last 12 months. 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.

Shooters Who Drive You Nuts — The Seven Insufferables

EDITOR: Given the flood of SHOT Show product reporting this week, we thought a little comic relief was in order this Friday, the last day of SHOT Show 2018. This clever video pokes fun of some of the oddballs you’ll find at shooting ranges. Crack open a cold one and have a laugh…

This very funny video that should put a smile on your face — especially if you’ve ever competed in action shooting events. This tongue-in-cheek video from the SuperSetCA team identifies seven (7) annoying/insufferable types of shooters you’ll find at shooting matches. You can’t help but chuckle watching this video. The satire is “dead on” — we’ve all met these kind of clowns at one time or another.

Seven Types Shooters Comedy spoof lampoon

Among the personality types lampooned by the video are the “way too serious” type, the completely unprepared type, the “Hollywood” show-off, the “always an excuse” type, and of course the “I’m too old for this” competitor. As a shooter past age sixty, this Editor might even fall into that category — at least when it comes to “run and gun” games. When I’m asked to gallop around a range carrying heavy gear, yes I’ve been known to mutter: “I’m too [insert swear word] old for this….”

Seven Types Shooters Comedy spoof lampoon

Here’s an extra challenge for you. According to the video’s producers, there are several TV and/or Movie references sprinkled throughout. Can you name them all (with run-times)? (Hint, look for Lethal Weapon and Matrix spoofs).
