Some AR News (?)

[SAWMAN]

Received the latest edition of "Book Of The AR"(Guns and Ammo) a couple of days ago and found a couple of things "interesting".

They did a survey of "military and law enforcement professionals" and came out with these stats in Re. to how these individuals preferred their AR's configured. BUT....keep in mind that the people surveyed were not people like us.....target shooters,plinkers,hunters,collectors,etc.

Caliber/Chambering -- 5.56/79%;6.8SPC/8%;7.62NATO/5%;6.5Greadel/3%;223Rem/3%,223Wylde/>1%;50Beowulf/<1%

Charging Handle -- Extended Lever/60%;Standard Profile/32%;Ambi/8%

Trigger Weight -- 4.5lbs/32%;4lbs/28%;5lbs or more/16%;3lbs/16%;3.5lbs/8%

ALSO ---> The first AR Chambered in 300Win Mag has come out. It is produced by New Evolution Military Ordnance(NEMO) and is called the OMEN.

Good Shooting To All --- SAWMAN

Thanks for sharing. Interesting information.

Most of those are what I would have picked also. However, I don't really understand this one , "Bayonet Lug -- NO/52%;YES/48%". I'm guessing the LEOs said 'no' and the military said 'yes'???

Who uses a bayonet anymore? Does a M203 require it to be mounted? I know there are a few accessories made like bipods, that will attach to the lug, but if you have a rail system, you don't need it.

 

[Stanley13]

What no grenade launcher attatchment stats wtf losers don't come after me with ur wimpy 5.56.Hahahhahahahahaha

 

[SAWMAN]

Yeah Pat...didn't really understand that one either. IMO,....NO application for it in the civilian world. In the military application,I really don't know if anyone even carries a bayonet anymore. Me ---> if I'm going H-->H I'm throwing down my long gun and either coming out with a pistol OR...in the WCS will use my Randall in my right hand and keep my left hand available to parry with anyway.

Another one that I don't understand is ....the bbl twist rates. I can surely understand why someone would opt for a 1:7 or 1:8. Even a 1:9(somewhat),however the rest (10,11,12) ??????? Shucks...I had a 24" 1:7 in Maine that I used for calling yotes. It shot the 40gr NosBalTips and the 45gr Remington HP's just fine. The 40gr NosBalTip was explosive hitting a woodchuck at 3700fps+. Adding the results up,the 7 and 8 twists account for 79% of the people. The rest COMBINED is only 21%. Sooooooo....really wondering why so damned many 1:9's out there if only 13% of the people surveyed "like" them. My guess......when it comes to the twist rate of a AR....not many know,or even care, about bullets weights(length's) and twist rates. --- SAWMAN

 

[JohnAL]

I would guess 9 out of 10 people have no clue about twist rates.

I have no clue what differ twist makes but if simple answer then I would love to hear why?

From Wikipedia:

Rifling is the process of making helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis. This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.
Rifling is often described by its twist rate, which indicates the distance the bullet must travel to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), or "1 turn in 254 mm" (1:254 mm). A shorter distance indicates a "faster" twist, meaning that for a given velocity the projectile will be rotating at a higher spin rate.
The combination of length, weight and shape of a projectile determines the twist rate needed to stabilize it – barrels intended for short, large-diameter projectiles like spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm).[1] Barrels intended for long, small-diameter bullets, such as the ultra-low-drag, 80-grain 0.223 inch bullets (5.2 g, 5.56 mm), use twist rates of 1 turn in 8 inches (20 cm) or faster.[2]
In some cases, rifling will have twist rates that increase down the length of the barrel, called a gain twist or progressive twist; a twist rate that decreases from breech to muzzle is undesirable, as it cannot reliably stabilize the bullet as it travels down the bore.[3][4] Extremely long projectiles such as flechettes may require impractically high twist rates; these projectiles must be inherently stable, and are often

Basically the required twist rate for sufficient stabilization is dependant on the bullet length weight and velocity.

You condensed three paragraphs into one sentence. That wiki author is not going to be happy.

 

[SAWMAN]

What's this about a "80-grain 0.223 inch bullet". Jeeeeeeeeeze !!! :crazy: --- SAWMAN

 

[Snow Bird]

An AR in 300 Win Mag should be called OMG. I wouldn't even think about shooting that thing. My shoulder would be in Ga if I shot it in Fl. And rapid fire.....NO.

 

[Patoz]

Bill, you have to rotate your AR 90* CCW (if you shoot right handed) and 'throw' the bullets at your target like the 'bangers' do!

LOL
I just loaded up some 70 gr. today. Dang those things are long. Maybe with my 7" twist they will shoot okay.

 

[SAWMAN]

Lemme know when you want to come over to shoot again John. I need to shoot a couple of the guns that I have been doing some "work" on. A couple of 6.8 loads also. --- SAWMAN

 

[JohnAL]

You call it. I'll be there. Nothing scheduled in the near future.

I've shot up Hornady 75 gr using my 20" 1 in 7 twist and 16" 1 in 8. Both shot accurately out to 340 yards. I have not tried at farther targets.
