AR15...What Caliber for Those Long Shots?

[Merc1138]

Awesome contribution but its those witty short one liners keep the post count up huh?? .... Find a life yet?

Hey, you're the one who got butthurt, started going about military snipers, battle rifles, and drove the thread off topic, yammering on about AR-10's, then showed yourself to be a zumbo with that "military platform" nonsense. Mad because you don't know who Zumbo is? Try google sometime.

That may be of use to you. There are a lot of wildcats out there that apparently run in the AR platform. I'd be plenty skeptical unless someone I knew had one and I could run it for a bit. I don't really like wildcats, which is why I suggested the 6.8, the 6mm Hagar has brass made by Hornady, so I consider it a manufacturer supported wildcat.

Ronin2;

Again, and for the last time WHY IS THE AR 10 SYSTEM BETTER FOR THAT KIND OF WORK? You have yet to answer that even though you have repeated that statement three times in three separate posts.

I just told you, overall the AR-10 is a more accurate platform than those other 3 rifles.

The FN/HK where made more for their durability, The M1A tries to fill the difference, but needs to be worked on to help it out, and still the M1A wasn't made to be the shooter the AR is.

There is a reason why even in competition and combat, the M1A is second to the AR system, and that is because the AR is a simpler, less complicated rifle- one you don't always need to fight to make hits.

I will concede/ agree with the point you made about the stock triggers on the HK and the FN but the triggers have nothing to do with the guns accuracy. They have much to do with the skill level needed of the shooter to be accurate.

REALLY ?

Who wants to 'work' at shooting a rifle, when other designs ( ar system ) work WITH you. Really ~ You want to struggle to make the hits ?

Why don't you just move on to a better, simpler working system that will help you ( being easier to shoot ), and require less work to maintain it's workability

The military did a over view, and the AR ( 10 ) system is what they are ( in part - not including the 338 lm/50bmg ) going with.

I bought my FN's, H&K's, and M1A's, because I knew what they where, BattleRifles that where made to fill a role in combat ( circa 50's/60's ), But I do not deny that other Rifles work better than those designs, because If you want to shoot 'long range' ~ there are platforms that are more suited to that type of shooting.

I'm happy with what I have, if I haven't answered your question ( a 4th time hahahaha ) , oh well that's life. And for raising your caps on me, I'm taking back my picture. hahahaha

This isn't my thread or anything but can you guys maybe take your sh*tshow somewhere else?

sh*tshow ?

I gave a response, and was challenged. I explained why the AR system is a better rifle, and still more challenging questions.

I think I can defend my own post. So unless I start dropping bad names, don't imply that I am starting a chetshow son.

This is THE ONLY useful post in this whole thread! It's kinda sad how a couple people made this thread such a wreck, I feel like I stumbled into off topic.

OP do you reload? If not you should. Many people consider it a prerequisite for long range shooting. If you already do reload , read THIS.

If you don't want to reload, I'd probably just stay with .223, build a nice heavy barrel 1:8 twist (or faster) upper and shoot Black Hills 75gr match. It's really good stuff. I wouldn't call .223 a good long range caliber, but it is a fantastic medium range chambering! With an accurate rifle, .223 isn't even fun inside of about 250 meters, gets challenging around 600 m, and on a calm day can hit 8" steel most of the time at 850 m. (850 m is the farthest I've have access to.) If you don't regularly shoot out past about 600m, I'd probably also stay with .223.

That said, I'm strongly considering building a 6mmAR Turbo 40 Improved caliber upper. For accuracy, 6mmAR will smoke a .308, the only reason people use .308 in competition is because the rules make them. So don't let the AR-10 guys give you a hard time.

6.5 sounds like a great choice for building an accurate ar,
However you might consider a 5.56 with a different twist that will allow you to shoot heavier bullets and that will extend your range and options, the 223 with the right barrel/twist/bullet can be very sweet

Aaaaaaand it is Ronin with the threadjack, whining about how the AR15 isn't a true rifle. That didn't take to long.

[Mr_Monkeywrench]

I have been reading that the 6.5 Grendel really shines at 120gr. I would really like to shoot one to see for myself one day.

The AR15 is NOT a rifle and the 5.56 NATO is NOT a rifle caliber. The AR 15 is a "carbine" shooting a carbine caliber...the 5.56 NATO. A lot of AR owners will disagree with this statement but they are in denial...nothing more.

a gun that has a long barrel and that is held against your shoulder when you shoot it

The M-16A2/4 or an AR-15 with a 18+ inch Barrel is considered and classified as a Rifle

a light short-barreled repeating rifle that is used as a supplementary military arm or for hunting in dense brush

The M-4 or an AR-15 with a 16 inch or less Barrel is considered and classified as a Carbine (until you get into 10" or less where some classify it as a PDW)

Let me know when the military and LE sniper communities move to the 5.56 /6mm platform. Until then trying to make the 5.56 something it is not simply makes one look silly....

Well dont you look silly then because both the Navy SEALS and the United States Marine Corps Use the Mk-12 SPR. In the Marine Corps it is used as a DMR, and also depending on the Battalion is also used by Sniper teams. This way whoever is Carrying the M-40 can also have a highly accurate while still fairly light backup platform instead of just carrying an M-4.

So are you done trying to compare a intermediate Rifle cartridge to a Battle rifle Cartridge to a Heavy Machine Gun cartridge.

We get it, your cool because you have a Semi-Automatic M-2. Wow, Congrats to you.

My next build is going to be a 6.5 grendel. From what i've read, its the longest range cartridge that you can get out of an AR15 platform.
