Ammoland.

For example, consider a rifle chambered in 6.5 Creedmoor, the ammunition loaded with a 140-grain Hornady ELD Match bullet. Muzzle velocity is 2,710 feet per second, and the rifle is set with a 100-yard zero.

At the same altitudes, but at very different barometric pressures, the bullet drop between these two scenarios is significantly different. For an extreme example, Ballistic Pro Shooter Logan Brown notes that at a high barometric pressure of 30.00 versus an extremely low pressure of 25.00, the difference in the above bullet’s trajectory at 1,000 yards can be nearly 30-inches. That’s huge!

Best advice: Logan says to update your Atmospheric Conditions on Ballistic as you move from place to place, and as weather fronts move in and out. Ballistic will automatically recalibrate your projectile’s trajectory based on the atmospheric inputs and changes to those inputs, placing you on target no matter the conditions.

He doesn’t give units, but he means 30″ Hg (to be precise, 29.92″ Hg).  And I’ve seen lower than 25″ at the top of Mt. Mitchell before, plenty of times (in the 22″ – 24″ range).

I’ve never loaded this app, but it makes sense to become familiar with it if you’re going to shoot during conditions not similar to where you zeroed your rifle.

Ridiculous news.

Bottoms explained that the shooting violence is “happening across the country” and is a combination of a “lack of access to healthcare,” unemployment, coronavirus and injustices seen across the country. She then added that Georgia is an “open carry state,” which allows people to “walk down the streets with assault weapons” without being stopped for probable cause.

“What’s happening in Atlanta is what’s happening across the country. There is a combination of things,” Bottoms replied. “There are … these systemic issues, including lack of access to healthcare, including people being unemployed, people are dying of COVID-19. We witness the injustices that have happened in front of our eyes, and it’s boiling over into our streets. It’s happening in Atlanta. It’s happening across the country.”

“The irony of it is that our overall crime rate is down by 18%. But in Georgia, an open carry state, people are allowed to walk down the streets with assault weapons and we don’t have probable cause to stop them,” she continued. “You don’t get to pick and choose which demographic you get to stop and question as to why they are walking in our streets with open weapons. It is an issue in Atlanta. It’s an issue in other cities across this nation, and it is one that we take very seriously.

Shut up, she explained.

So no I won’t shut up.  And I’ll explain a few things.  Braselton, Ga., has a violent crime rate of 0.09 per year per 1000 residents.  And yet open carry is legal in Braselton just like it is in Atlanta.

The Atlanta crime rate, on the other hand, is 7.69 per 1000.  So now that I’ve explained this, I’ll turn it back over to idiot mayor Bottoms.

Take it away.  Now explain how open carry is responsible for crime in Atlanta.  Go ahead.

The moral of the story is that bird shot may be okay for very short range, but is certainly not viable for longer range self defense applications.

I have a Remington R1 1911 chambered in .45 ACP. Arthritis has invaded my hands and it’s getting harder for me to rack the slide. Would putting a lighter recoil spring in it be a bad idea? The factory recoil spring is 16 pounds. I bought a 12-pound spring for it, just to see if it solved my racking problem, and it did. I haven’t shot it yet, and I would like to get a knowledgeable opinion on it before doing so. The only thing I have been told so far about putting the lighter spring in it is that the recoil would be increased. I’m not as worried about that as I am about risking unnecessary damage to my pistol. While I’m sure other shooters have this same difficulty, I don’t know anyone in my area who does. Any insight and/or suggestions regarding how to tackle this challenge would be greatly appreciated.

While the recoil spring helps to attenuate recoil of the pistol, its main job is to return the slide forward, which strips the next round off the magazine and fully closes the pistol with the barrel and slide locked together, ready to fire the next shot.

The first thing I would do to aid in the function of the gun and help to prevent impact damage of the internal parts is to add a Wilson Combat Shok-Buff, or equivalent, to the recoil-spring guide for the lighter recoil spring to rest against. The Shok-Buff is a polymer shock absorber designed to help prevent slide and frame battering as they transition through the cycle of operation.

[ … ]

Keep in mind the recoil spring and Shok-Buff are being worked hard with the lower-power rating of the spring and should be replaced at 500-round intervals or when obvious signs of wear are evident. The Shok-Buff will start to lose its shape and the recoil-spring length will shorten by several coils, indicating it’s time to replace them.

To begin with, I’m no stranger to severe RA in my hands.  Mostly, my right hand (shooting hand) is affected.  It is affected to the point that my hand appears deformed, and I usually hide it when I meet people.  It helps to put my hand in my pocket.

RA is caused by the same affliction as Psoriasis, that is, an overactive and confused immune system.  My immune system thinks my cartilage is a foreign object and attacks it, making scar tissue of it.  I have thus far refused to take a biologic like Methotrexate, and so I simply make it by day to day.

So I sympathize in the superlative with the writer.  With that said, I find no discomfort in shooting .45 ACP.  I enjoy it more than shooting any other round, and I enjoy shooting a 1911 more than any other firearm.  I also find that the best thing for me is to exercise, and that means not being courteous to my RA.  The more I can push myself, the better off I am.

One of my [modified] 1911s came with an 18# spring, not 16#.  I didn’t know that the Remington came with a 16# spring.  That seems a little light to me.  Readers may recall that I replaced my 18# spring with a 22# spring from Wolff Gunsprings for my trip to the Weminuche Wilderness.  I did that so that I can shoot 450 SMC out of that gun, achieving 1120 FPS with 230 grain bullets (the 450 SMC has to be purchased from Double Tap Ammunition).  I still have that gun modified that way, although it’s an easy spring switch to change it back if I wanted to.

I also find that it eats all other .45 ACP ammunition flawlessly.  The heavier spring doesn’t cause problems with normal bulk range ammunition, although I wouldn’t shoot 450 SMC out of my other 1911s without a similar spring modification.

Double Tap and Buffalo Bore make very hot .45 ACP +P ammunition (~ 1000 FPS), and the heavier spring would work well with that choice.  If I switched to a light spring, like the analyst said, I would want to make sure I had put it through its paces to see what ammunition worked well with it.

As RA progresses, I wouldn’t be opposed to changing to a lighter spring, but I’m a long way from that.

The rate of gun background checks and purchases has skyrocketed.  Writers Phillip Levine and Robin McKnight explain the data, but the graph below show virtually everything you need to understand this.

But this doesn’t explain the real problem that the progressives have with all of this.

You see, the schedule got mixed up, and it’s causing no end to the hand-wringing among the social planners and elitist chattering class.

There are more guns than people in the United States (400 million are in circulation for a population of 330 million).  In just the first six months of 2020, approximately 19 million firearms have been sold, representing more than one firearm for every 20 Americans.

The presence of so many guns complicates discussions of public policy. Injustices committed by the police, and systemic racism in society more broadly need to end. It is concerning that the necessary national discussion regarding racial injustice is leading to even more firearms in the hands of Americans.

This concern is particularly relevant in the context of discussions regarding defunding the police. When public goods are not provided by the government, or are provided on a scale that some consider to be inadequate, individuals turn to private provision of these services.  For example, parents often turn to private schools when they perceive public education to be inadequate.

Similarly, it would not be surprising for some citizens to respond to perceived limitations on police services with private provision. This may include purchasing more firearms. In a society fraught with racial tension, it is not clear that dismantling the police and seeing more private citizens purchase guns will lead to a safer world. Increased firearm sales are a potential – if unintended – consequence that merits attention as we endeavor to create a more equitable society.

They said this with about as much adroit skill as can be managed, but the mask slipped down nonetheless.

To begin with, it’s always been a myth that the police were there for protection.  Regular readers, and most other educated men and women, already know about cases Warren versus D.C. and Castle Rock versus Gonzales.  There are more, but these two cases demonstrate that police are not duty bound to offer anyone protection.

But at least it’s a myth that many people have believed.  The riots, looting, pillaging, beatings and murders of late have convinced many uninformed folks that maybe they do need protection in lieu of police.  In short, that myth has been shattered.

Here is where schedule comes in.  The social planners want America to be disarmed, and see it as an impediment to their plans that men and women can defend themselves.  To these writers, this is all an obstacle to be overcome.  T. S. Furey at NRO explains a related problem.

June has been marked in recent years by a flurry of orange-clad marchers promoting National Gun Violence Awareness Month. This year’s planned gatherings, however, fell victim to the COVID-19 pandemic and were overshadowed by Black Lives Matter’s nationwide protests against institutional racism within policing. But the gun-control lobby’s reticence isn’t out of respect for the lives of George Floyd or Breonna Taylor but rather concern for its own preservation.

For decades, gun-control advocates promoted greater police power as well as known practices of institutional racism within police firearms-licensing divisions. Now that there are calls to “defund the police,” many leaders of the gun-control lobby, who are mostly white, should rightly fear that their history of siding with the police and promoting policies now deemed racist by progressives may make them the next casualty of cancel culture.

Progressives tend to eat their own.  The next most progressive manifestation uses the previous generation as food.  What is a good progressives to do?

On the one hand, they are pro-police, since that is the backstop for their gun control plans.  Pushing the myth of police protection has been their staple for decades.  On the other hand, siding with the police makes them anathema to the current manifestation of wokeness.  On the one hand, most progressives have sided with the rioters, looters, thieves and arsonists, and on the other hand, as that metastasized in America it has led to even more guns in the hands of men and women who now know that they have to defend themselves.

The good news for the progressives is that this is all just a fabricated problem.  Yes, many guns have been sold in the last few months, but hundreds of millions were already in the hands of men and women who already knew or are learning how to use them.  In addition to that, trillions of rounds of ammunition are in the hands of civilians in America.

It’s far too late for the progressives to worry over a few more guns.  That battle was lost years ago, and no law or social planning can turn it around.

Here is the real worry that should be keeping the progressives up at night.  I said earlier that police protection is a myth.  Yes, to some degree, at least in theory and law.  But not in practice.  In practice, most of the police protection in the last two or three months has been for the rioters, looters and arsonists.  The police are there to protect the criminals from the otherwise peaceable men and women, not the peaceable from the criminals.

The worry for progressives is that this abates one day soon, and the police turn their backs on the rioters.  That will be an awful day for the rioters, because they have subsisted on the backs of police protection these last months.  That’s the ultimate irony.  The police have worked thus far to protect the rioters and arsonists because of local politicians.  But local politics is a fickle thing.

The writers can actually take solace in the fact that their hand-wringing is to no avail, and they should just try to get some sleep rather than worrying over any of this.  These wheels were set in motion long ago, and more violence will only lead to bloodshed.  Violence can take many forms, from rioting and looting, to theft of property for so-called “reparations.”  More pressure by the social planners to change anything will eventually lead to more problems.

The barrel features spiral fluting in three distinct areas that increase exterior surface area to increase heat dissipation during firing. Fin height gradually tapers but widens toward the muzzle end, providing an unusual profile to the design. Barrel weight is a quarter pound less than that of the currently issued M4A1 version.

CDCC indicated the design may be applicable for other weapons systems currently fielded by the U.S. Military. Enthusiasts may soon see versions available on the commercial market because, “The patented design is available to companies that would make, use, or sell the barrels,” according to the announcement.

Well, it will certainly increase surface area, and thereby lead to increased rate of heat dissipation (or heat flux).

However, each spiral is a stress concentration point.  I prefer to wait on proof before I make a judgment on this, and I would likely never purchase this design.  Time will tell.

The only one I’m somewhat familiar with is the Holosun.  The Holosun is quickly gaining a very good reputation.  But where are the FDE models?  They don’t exist.

If you want a FDE model, you have to go with the Trijicon RMR.

Or something like that.  This video comes from TFB, and I confess that I’ve never been able to become a fan of the bullpup design.  Don’t like the looks.  Don’t like the explosion occurring near your ear.  But linked at the video was his first design.

I’d spend money for something like this.  I hope he licenses his design to someone and it becomes massed produced.  But I’m not sure why he’s got the scope turned around like that.

Somehow I missed this when it came out.

I’ve shot a lot of rounds through wheel guns, and I guess I’d never thought much about these things.
