AR-15 Ammunition And Barrel Twist Rate

Herschel Smith · 19 Feb 2017 · 7 Comments

There are a lot of articles and discussion forum threads on barrel twist rate for AR-15s.  So why am I writing one?  Well, some of the information on the web is very wrong.  Additionally, this closes out comment threads we've had here touching on this topic, EMail exchanges I've had with readers, and personal conversations I've had with shooters and friends about this subject.  It's natural to put this down in case anyone else can benefit from the information.  Or you may not benefit at…… [read more]

Surefire Releases New Pistol Lights

BY Herschel Smith
1 week, 4 days ago

From TFB.  1000 lumens.  Maybe it’s just me, but I think we’ve beat the lumen horse dead.  There’s essentially no difference between 800 lumens and 1000 lumens to me, or even less than that.  They are all so bright that it can blind you when the light scatters off of walls, especially if the walls are white.

Here’s what interests me.  A simple tactical light.  As they grow more powerful, they have also grown more sophisticated.  In a high stress situation a person won’t be able to go through the various settings to select the right one unless it’s pure muscle memory, and it won’t be muscle memory unless you use that light all the time in tactical situations.

U.S. Virgin Islands Governor Orders Confiscation Of Weapons In Advance Of Hurricane

BY Herschel Smith

David Codrea:

“U.S. Virgin Islands Gov. Kenneth Mapp signed an emergency order allowing the seizure of private guns, ammunition, explosives and property the National Guard may need to respond to Hurricane Irma,” Michael Bastasch reported Tuesday at The Daily Caller.  “The order allows the Adjutant General of the Virgin Islands to seize private property they believe necessary to protect the islands, subject to approval by the territory’s Justice Department.”

David updates the article with an attempt at damage control that actually makes matters worse, essentially saying that not only can they do this, they regularly do it as a matter of course and they have the right to do it.  At least that’s the way I read it.

I’ll point out a few things.  First of all, there is the British Virgin Islands and the U.S. Virgin islands.  The two are not the same thing, and this is occurring in the U.S. Virgin Islands.  Second, while the people there are technically considered U.S. citizens, they aren’t treated that way.

For example, the U.S. Code (48 U.S. Code 1561) outlines a bill of rights for their citizens that doesn’t include any hint of bearing arms.  This seems to me to be ripe the litigation before the SCOTUS, but apparently that’s for another time.

Third, even though no one can effect change in the confiscation at the moment, this does go to show the first reflex of collectivists.  And you do understand how they know who has firearms, don’t you?

Finally, in a somewhat related vein today I saw a discussion thread at reddit/r/firearms that needs to be addressed.  When responding to a post that compared these confiscations to those post-Katrina, one commenter said this.

No, what happened in Katrina was very different. The order in Katrina was given by the local police superintendent, not the governor. As well, the overwhelming majority of those confiscated in New Orleans were abandoned in houses or forfeited upon being rescued when people were taken to refugee sites. By in (sic) large if a person wanted to stay in their home with their gun, they could.

This is simply a lie, and the commenter knows it.  The comment sounds like it was written by a LEO or former LEO, but it’s wrong in the superlative degree.  There were weapons confiscations done forcibly, i.e., without owner consent, and those weapons were either never gotten back or were in such bad shape (having been cared for poorly) that they were non-functional.

They were returned only because the NRA sponsored a lawsuit to force return of the weapons.  Those confiscations were conducted by local police and military contractors (insert groups like DynCorp here), with supplemental manpower and backup provided by the Louisiana National Guard under the command of Russel Honore, who is proud of his gun confiscation efforts during Katrina.

Mother Chases Away Home Invader Using Handgun

BY Herschel Smith

The Chronicle:

ELYRIA – A mother of three chased a would-be burglar out of her house with a pistol after he broke in just before 8 p.m. Monday.

According to a police report, Brett Santo, 33, of Chestnut Street, walked into Sarah Long’s home on Fourth Street and approached her 15-year-old daughter. Long’s 17-year-old daughter was the first to see Santo and screamed, launching Long into action, police said.

Police said Long grabbed a pistol by her bed and she charged at Santo, but dropped the gun while in her home. She and the 17-year-old then chased Santo out of the house and down the sidewalk until they lost sight of him by St. Mary’s Church.

Officers were dispatched to the area on a report of a burglary suspect fleeing the area and Long was able to provided police with a description.

Police found him on Third Street between Middle Avenue and Court Street and he was arrested and charged with burglary.

During the ride to the police station, officers said Santo “let out an excited utterance that he in fact did burglarize the house,” police said.

Long said Tuesday that Santo had entered her home once before but left when confronted and Long didn’t call police. This time, Long said, Santo approached her daughter so Long sprung into action.

“I said, you picked the wrong (expletive) mother,” Long said, “I ran after him over the bridge and he turned around and was like, is this (woman) still chasing me.”

It was by chance that Long said her gun was near by. Her boyfriend, who Long described as “a big biker guy” had just left the house and encouraged Long to have the pistol ready.

“I’m thanking God it was by a fluke he told me to put that gun by me,” Long said. “Santo was walking in there like he didn’t care, like this time he wasn’t stopping.”

She didn’t have all of that super secret Ninja warrior stress control training like cops, and she even dropped the gun.  And yet, she was safer with the gun than without it.  Somehow this doesn’t fit the narrative told by either cops or the gun controllers.  They would have wanted her to die.

Cop Shoots Photographer When He Mistakes Camera And Tripod For A Gun

BY Herschel Smith
2 weeks, 2 days ago

Via David Codrea and reader David Dietz:

A small Ohio news organization says one of its photographers has been shot by a sheriff’s deputy who apparently mistook his camera for a gun during a traffic stop.

The New Carlisle News reports photographer Andy Grimm had left the office at around 10pm Monday to take pictures of lightning when he came across a Clark County sheriff’s deputy performing a traffic stop in New Carlisle, north of Dayton.

Grimm tells the news organization that he decided to take pictures of the traffic stop on Main Street, noting that he was not the one being pulled over.

He says he got out of his Jeep and started setting up his tripod and camera in full view of the deputy performing the traffic stop when he heard, ‘pop, pop,’ and then realized he’s been shot in the side.

Grimm was taken to Miami Valley Hospital, where he underwent surgery. He is expected to recover.

The wounded photographer later said Deputy Jake Shaw gave him no warning before opening fire on him.

Hmm … [with chin resting on fist contemplatively] … I hate it when that happens to me.  I remember the last time I did that.  I shot up some old dude walking with a cane, and I thought it was a gun.

Fortunately, the cops did an “internal investigation” and found that I was entirely within my rights.  No harm, no foul.  Except for the old guy I shot up.  Too bad for him.

NYPD Officer Kills A Charging Pit Bull And Accidentally Shoots A U.S. Marshal In The Foot After Firing Four Times At The Dog

BY Herschel Smith
2 weeks, 3 days ago

Reader David Dietz sends this along.

A New York City police officer hunting for a fugitive in Jersey City accidentally shot a U.S. marshal in the foot while firing at a dog on Thursday morning.

The officer from the warrants task force was with members of a fugitive task force looking for a 25-year-old man wanted on robbery charges, according to the police report.

As they reached the door where they believed the man was hiding at about 6.40am, a pit bull charged at them and bit one of the officers.

The officer fired at the dog four times killing it and hitting the marshal’s foot.

The dog was only doing what it is bred and trained to do, i.e., protect its master.  But remember boys and girls, only sworn law enforcement officers are endowed with the ability to recognize peripheral threats, know your backstop, and think through tactical situations quickly by utilizing their Ninja warrior stress control training.  You can’t be trusted with such things.

A federal marshal got shot.  The sad part of the story is that the dog died.

From TFB.  Those who live in big bear country can weigh in, but it looks to me like .44 Magnum is enough to get the toughest job done.

Open Carry In Publix Grocery Store In Gastonia North Carolina

BY Herschel Smith
2 weeks, 4 days ago

So I was shopping in Publix grocery store this weekend, and ask a manager about their policy on open carry.  I thought I had seen folks engaging in open carry there, but I told the manager that I knew businesses can have their own policies, which I support, and I didn’t want this to be awkward for them if I come back openly carrying.

He informed me that he has a number of customers who open carry, and Publix follows the laws of the state.  There is no problem with it at that store.  I appreciate their stand on the issue, and I will certainly reward them by continuing to shop there.

In case we’ve never discussed this before (and I think we have), I open carry because I hate concealed carry and told the manager so.  But there is a larger and more important reason.  I open carry “For the peace, good and dignity of the country and the welfare of its people.”  I owe that expression to Jeremy Bryant.

Mountain Biking Payoff

After you’ve done the workout, put in the effort, and sweat several liters of water doing the climb, it’s good to get the payoff.  For me, it was downhill singletrack heaven pretty much the rest of the way out to the trailhead.  I earned this payoff.

Have a great Labor Day!


States Where Open Carry Is Permissible

BY Herschel Smith
2 weeks, 4 days ago


This means 12 states recognize the Second Amendment as your concealed carry permit. The states are Alaska, Arizona, Idaho, Kansas, Maine, Mississippi, Missouri, New Hampshire, North Dakota, Vermont, West Virginia, and Wyoming.

I’m not quite sure where Hawkins gets his information, but 30 states allow unpermitted open carry, my own state of North Carolina being one of them.  Fifteen states allow permitted open carry, and open carry is only prohibited in five states: California, Illinois, Florida, New York and South Carolina.

It should be embarrassing to South Carolinians that you’re on the same list as California and New York.

What The Main Stream Media Will Never Show Or Tell You About Antifa

BY Herschel Smith

The group’s website also seeks to abolish of gender and calls for its members to steal tools and lands so that it can build its own state, independent of the United States.  RAM also plans to build local “defense teams” and councils as well as national councils.

The group models its movement on the far left Rojava Revolution in Syria, and praises communism as providing a “foundation in communal and council based political organization and militant defense.”

A website video rife with anarchy and violence heavily hints at an armed revolution to destroy the government.

One of my commenters, Fred, said this.

I’m not a fan of genocide so this has my attention. The fact that I appear to be on the menu for genocide has my undivided attention. It should be noted that both the right and the left want Christians gone so I’m back to neutral. Events may dictate any number of things. If either side wants to hang me on a cross so be it but I ain’t nailing myself to it. People are going die, lot’s of people. As you and many commenters here have noted, Jesus was not pacifist pussy.

These guys will eventually be arrested – all of them.  They are nothing more than the shock troops for the deep state, just like the Sturmabteilung, and the Night of the Long Knives will come for them too.  But it behooves us to be paying attention to the cold winds, just like Fred.
