The Firing Pin (Gun thread)
 
This is the only place I figured this thread would fall. This thread is for the hunters, shooters, collectors, it's basically the "gun thread". We can use this thread to learn, show, and teach...

Ill start with a small tidbit of uncommon knowledge most do not know. Most should all know that the Modern semi-automatic rifle known as the AR-15 was designed by Eugene Stoner.... What very few know is that AR stands for.... It is not "Assault Rifle", its not "automatic rifle", it actually doesn't have the word "rifle" in it.

AR is an abbreviation of Armalite, the company Eugene Stoner worked for when he designed the AR-15. If you go to Armalite's website you will see that they still use the AR designation today and also on weapons not associated with the AR-15.

Here, browse their pistols they all start with AR in the nomenclature.

Gun "worth" is subjective Danno. Does it make it more reliable or more accurate? Probably not.... Does it make it more appealing to some? Yes.... and no.

Do you not have to worry about the bluing staying on if its SS? Obviously

Some would pay an extra $200 for gold plated tiger stripe. I wouldn't.

Personally, as you can see, I don't care for SS. Too shiny for me and if I need to use it in the sunlight I don't care to be blinded by the sun if the glare hits me in the eyes.

Tried to find a set of forums where after three pages there was a conclusion other than personal choice and I couldn't find one.

If you run over to 1911forum.com and search you will find a few threads on the exact question.

Correct, the Colt 1911 .45 ACP was the preferred pistol in WWII. For the most part that model with little variation has been in service since.... Yup 1911.

Difference between .223 and 5.56 NATO. Same goes for .308/7.62x51 NATO)

Short story: you can shoot both .223/5.56 NATO in a 5.56 chambered rifle. You can only shoot .223 in a .223 chambered rifle (SAFELY).
You can shoot .308/7.62x51 in a 7.62x51 chambered rifle, you can only shoot .308 in a .308 chambered rifle (SAFELY).


Some will tell you it is because of pressure, while that is the truth, it would help you to know the root cause of the increase pressure, and why it is that way. (Keeps people from thinking I'd they have a lower P 5.56 round they can shoot it in a .223 rifle).

The 5.56 round is neither a lower or higher pressure round than the .223.

The increased pressure is a function of two things.

.223 Smaller leade : The area between the chamber and the barrel rifling.

This could get deep so ill simplify.

.223 tighter tolerances
5.56 more durable looser tolerances (due to military durability requirement)

Essentially each time you try to chamber a 5.56 round in a .223 you run the risk of the projectile being against the rifling before fired.


.223 is measured in SAAMI pressures

5.56 is NATO EPVAT pressures

If anyone want to read more let me know and I can provide links to more info.

Rule of thumb- for a semi automatic rifle I always buy 5.56 chamber as it allows me to shoot either cartridge.

Re: The Firing Pin (Gun thread)
 
The biggest educational item for me in regards to rifles is the subject of Optics for range shots. This article is excellent if anyone ever has the need for the education.

Scope Reticles 101
Which scope do you recommend? I get asked this question several times a month. I wish the answer was as simple as the question. There are several factors we should consider before making a choice. The next few questions will help clarify the proper response to the question.

What gun is it going on? Is it a semi auto 22 or a 300 WM bull barrel target rifle? Is it a 30-30 lever gun or an AK? The type of gun and the caliber are important factors in the scope and reticle choice. What do you plan to do with the gun? Self-defense has different requirements than hunting or target shooting. What caliber is the rifle? A 22 rim fire runs out of energy past 300 yards. What are the external ballistics of the round? How fast does it loose velocity?

It makes no sense to put an optic designed to shoot a thousand yards on a rifle/ cartridge that is not accurate at that distance. Here is an example. The 7.62x 39 cartridge velocity is approximately 1150 fps at 500 yards; at 600 it falls below 1000 fps. Generally 1000 fps is about the speed at which rifle bullets become unstable. This instability causes the bullet to yaw and wobble. The wobble changes the flight path. Based on my experience unstable flight path can vary greatly. I am talking about variation by feet, not inches. If you add in weather and wind factors the variation is increased. So a 7.62x39 or a 30-30 would not be a good rifle for a 6-20 x 50 target scope. A 1-4 or 2-7 or a low power fixed scope would be a better choice for these calibers.

On the other end of the spectrum is the 338 Lapua. This round at 1000 yards still has a velocity of 1680fps. This means the cartridge is accurate well past 1500 yards. Installing an Eotech red dot or a 3-9 power scope is limiting the capabilities of the cartridge. Generally speaking having 1 power of magnification per hundred yards is good if you are shooting man size targets. If the man ducks behind cover or goes prone you may need more magnification to find and shoot this now smaller target. Higher power will also aide in range estimation. On the down side, higher power can amplify movement as the shooter moves the gun. It can also be difficult to shoot through the mirage on a high power setting.

Now that we have the basics as to what we want to do with the gun/ammo scope combination (also called the weapon system). We can look at reticles for the scopes. There are hundreds of different reticles available for scopes. The early scopes had crosshairs and nothing else. Since the invention of crosshairs in scopes man has looked at ways to improve the basic idea by adding thicker lines or removing a portion of the crosshairs (also called stadia lines). Today scopes have 4 categories of reticles.

Standard Reticles Fine, Crosshairs or Duplex

Illuminated Reticles; Eotech, Aimpoint or Trijicon

Hold Over recticles; a bullet drop compensator type

Ranging reticles; Mil-dot or MOA hash marks

(Combinations of 2 or more can also be found.)



This article will examine standard reticles and illuminated reticles.

The standard reticles group includes the t-post, target dot reticles. The stadia lines may be tapered or have two different widths. Standard recticles are used to zero a rifle at a specific distance. That is about as basic as it gets. The turrets on the basic scopes normally do not have numbers or revolution marks to adjust them to different zero points. They are meant to be zeroed and left alone. These types of scopes work well on rim fire and hunting rifles designed for 200 yards or less. With some practice the shooter can use them for longer shots by holding over on the target. They have no value in ranging to the target and adjusting for wind or weather changes.

The variable power scope with a duplex type reticle can be used for ranging by using the points where the stadia line reduces from thick to thin. This method works by adjusting the magnification so that a known object will fit the reticle between the horizontal line and the point where the vertical line changes width. This requires practice and the shooter should develop a range card to record this information.

Here is an example. Your target is a deer. It’s size from the top of the shoulder to the bottom of the belly is 18 inches. Now use the zoom to set the horizontal line on the top of the deer’s back and the point on the vertical line at his belly. Now determine the power setting. Reference this number to your range card and read the distance to target. Then you can use the hold over you established during practice to make a hit. For this to work the shooter must put in the time to gather the information and build the range card. This same principal works for many different types or styles of reticles.

The newest style of reticle is an illuminated reticle. There are 3 sources of illumination, battery power, fiber optics, and tritium. Combinations of the three can also be found. The most simple of these is the battery power models with a round dot in the center of the lens. The red dot reticle can vary in size, shape and clarity. With variable power scopes and red dot scopes the quality of the glass can vary. Better quality glass will result in a crisp edge to the dot type reticle.

Try this little test. Pick up a cheap red dot and turn the power up to its highest setting. Notice the dot is not perfectly round; it can look like a star. Or it may have streamers coming from the center. While taking a sight picture rotate the red dot. See if the streamers rotate with the scope body. No streamers means the glass is of high quality. Another test is to take the red dot scope into the full sun and check to see if the dot is visible. In some of the economy models the dot will almost disappear. Next look at in in very low light. The dot should be visible but not so bright that you can’t see the target past the sight. The size of the dot makes a difference as well.

An EO Tech has a 1 min dot in a 65 min circle. These are designed to use the small dot for accuracy and the large circle for speed. The Aimpoint models have a 3.5 min or 8 min dot. For a rifle or carbine I like the 3.5 min dot. Why the smaller dot on a carbine? The dot covers up 3.5 inches of the target at 100 yards or 7 inches at 200 yards. I can still make a head shot at 200 yards with it. The 8 min dot would be 16 inches at 200 thus making a head shot hard. The average head is 8 inches wide. The Leupold Delta sight uses an illuminated triangle instead of a round dot. This gives the shooter an option: fast shooting at close range when referencing the entire triangle on target or using the top point of the triangle if a more precise shot is needed. I recommend zeroing the rifle at 200 yards to the top point of the triangle or the top edge of the round dot. Bushnell has a multiple reticle red dot that has a circle dot, a small dot and “T” style reticle. The shooter can select all three if needed.

Battery life is a big factor when using a red dot scope. The first models lasted about 24 hours before the battery died. The latest model Trijicon RMR will run more than a year before the battery dies. The Leupold has a motion sensor that shuts down after 5 minutes of no movement. The standard red dot sights do not have any magnification. Therefore, long range precision is no better than when using sights. If these are used on a rifle the shooter is limiting the performance of the weapon system. Power failure while using battery powered sights is the main reason for having back up iron sights on a gun. The other option is to use the scope itself as a huge ghost ring and put the target in the center and press the trigger.

Fiber optic illuminated red dot sights have the advantage of not needing a battery for illumination. No battery means no power failure. A benefit of the fiber optic system is the brightness level automatically adjusts to the ambient light. This also means it is always on. A few models even have a shade so the shooter can block some of the ambient light to reduce the reticle brightness. There are 3 styles of reticles for fiber optic scopes, a solid round circle, a triangle and a chevron (an inverted “V”). There are also color options of red, green and amber. I have used all three and I like the green the best. The red can disappear on a red target or on the red dirt here in Georgia. The green is a fluorescent green that has a good contrast in foliage. Also green is in the middle of the light spectrum and is easier for the brain to pick up. The amber blends in on fall days with flat light or in reduced light. To me green is the easiest color to pick up in a wide variety of light conditions. The size of the reticle is just as important on a fiber optic scope as it is on a red dot scope. Fiber optic scopes have one big advantage; the availability of magnification with them. There are fixed power and variable power scopes available with fiber optic reticles.

There are a limited number of scopes with tritium illuminated reticles. They work well in low light but are not bright enough by themselves to work in sun light. Normally these are combined with fiber optics to give the shooter a sight in very low or no light. One down side to tritium is they do not last forever. The half- life is 12 years.

For a fighting rifle I would only use a scope that will continue to work when the battery dies. If the battery dies and I can’t use the scope my effectiveness as a rifleman just diminished. We should all have the knowledge and skill to point shoot the rifle in CQB without the use of any sight system.

We covered the 2 basic types of reticles in this article. Both have their good points and drawbacks. Remember any time you get to look through a scope outdoors take the opportunity to learn about the scopes. Learning experiences are valuable specially if they are free. Part two of this article will cover hold over style reticles and ranging reticles.

High-tech, $20,000 TrackingPoint ‘smart rifle’ turns anyone into a sniper

Hitting a target at 1,000 yards is a skill only possessed by a few elite snipers. But all that is about to change, thanks to a high-tech bullet guidance system created by Texas gun manufacturer TrackingPoint. For better or worse, almost anyone with $20,000 to burn can soon have the skills of a special forces assassin.http://a57.foxnews.com/global.fncsta...ergun.jpg?ve=1
At the heart of TrackingPoint’s sophisticated firearms, dubbed the XactSystem, is the company’s “networked tracking scope,” which sports a color heads up display, and instantly monitors a wide variety of factors, including wind speed and direction, target distance, gravity, the rotation of the earth, and more, to calculate when and how to accurately fire the ammunition. TrackingPoint’s so-called smart rifles, which range from $22,500 to $27,500, even pack built-in Wi-Fi, which allows shooters to transmit live video of their shots to an iPad, then upload them to YouTube or social networks.


“They like to post videos; they like to be in constant communication with groups or networks,” TrackingPoint President Jason Schauble told NPR. “This kind of technology, in addition to making shooting more fun for them, also allows shooting to be something that they can share with others.”

Re: The Firing Pin (Gun thread)
 
Great technology but there are a few issues I have with it personally.

I cant find any evidence of "Bullet guidance" after it leaves the bore. Which means that it does not make a shooter an accurate shooter if he can not control his breathing and trigger squeeze. I see it being sold to the Military only IF it is durable and can with stand a combat environment, then there is an issue with the HUD in that the rifle becomes useless if for some reason it stops working. Lets say sub freezing temperatures where LCD's freeze.

Hunters that can afford it will buy it... Range shooters will not. Shooting for most is like golf, we do it for the challenge, the personal challenge of every shot being placed William Tell style on top of another. "If" it does what it says it does, it will be like a golf club that always hits a hole in one with one stroke... The entire 4 some will score the same. Not fun, just a novelty until it wears off.

As I understand it, you squeeze the trigger and the rifle only fires when the rifle decides its the best time to fire.

Laser gatling gun a real blast

Patrick Priebe, a German hobbyist with a knack for making laser weapons, has done it again and this time he’s gone and built a Laser Gatling Gun.
http://a57.foxnews.com/global.fncsta...rgun1.jpg?ve=1
Constructed out of durable aluminum, the gun’s spinning turret boasts six 1.4-watt Class 4 blue lasers. For aiming purposes, a 100-mW green laser has been mounted on one side of the gun. Although it looks like it could blast through five layers of concrete and steel, the gun is only strong enough to pop balloons.http://a57.foxnews.com/global.fncsta...egun2.jpg?ve=1
Four ball bearings spin the turret, which is controlled by a knob on the underside of the gun. Eight AA batteries power the aiming laser and motor, while the six blue lasers get their juice from four lithium-ion batteries.
Original Gatling guns were invented just prior to the Civil War and were some of the first rapid fire guns. Hand cranks were used to rotate six barrels and fired ammunition when each barrel reached the top slot. However, with Priebe’s creation, the Gatling-like rotation is purely ornamental. Despite how cool it looks, the gun’s rotation actually decreases the beams’ intensity, since lasers work by focusing on a single point with a heated stream of photons.

Smart gun technologies making weapons more accurate -- and more deadly

"Are there any legitimate gun owners who are calling for this technology for safety? I haven't heard of one," said Jim Wallace, executive director of the Massachusetts Gun Owners Action League, in a recent interview.http://global.fncstatic.com/static/m...oint%20gun.jpg
One example is a newly unveiled “supergun” from TrackingPoint that emulates the target-locking technology from jets to turn any rifle into an ultra-accurate sniper gun capable of consistently hitting a target from 1.75 miles away.
“With [this] technology, shooting a hunting rifle is like being a pilot in a fighter jet,” Jason Schauble, CEO of the Austin, Texas-based company, told FoxNews.com. “You tag a target, and lock onto it. Then you engage the target for a shot.”
'It won’t take years to learn to shoot long-range. Just minutes.'
- Jason Schauble, CEO of TrackingPoint
Other gun rights groups strike a more measured albeit still cautious approach.
