600 yard line ammo

[Smuckatelli]

Has anyone shot out to 600 yards with a carbine?

I'm specifically looking for ammo requirements to reach out to 600 yards with a 16.1 inch 1/9 twist barrel.

I think a 62 gr should be able to do it.......

600 yds with .223/5.56 is a stretch though feasible. Unfortunately with the 1/9 twist you won't be able to use the heavier 75/77 gn bullets. Match grade SPR M16's with 18" barrels with 1/7 twist shooting MK 262 (77gn, 5.56 load) ammo regularly hit at 600 yds, though you have to be good at compensating for the wind drift.

I'm hitting a 10in steel pie plate all day @ 610yards with a 77grain SMK out of my 16in LMT upper in a prone position. Don't have any load data though as it is factory Lake City ammo.

Is that a 1/7 or a 1/9 twist?

That's pretty much what I think also but I'm hoping that someone here has that one nugget of information about some ammo that I'm not aware of........

We were able to do 600 yards with no problem using M855 & the 20 inch 1/7 twist A2.

Smuckatelli,

Back in the day I shot M855 out to 500M quite often (M16A2). If you attend a good SPR Sniper Course you will find out that with the right weapon, ammo and glass 600 yds is no problem. During the course I utilized a rifle with an 18" barrel (I believe that it was a 1/8 twist) and Black Hills 77gr. match ammo. We fired all the way out to just under 900 yds. BTW- I was (still am) a novice at shooting with a scope and I was making my hits with frequency as were the other guys in the class. The most important element I believe was getting the correct range to the target and doing your dope correctly.

You can do it with a 16" carbine, but you will need at least a 1/7 or 1/8 twist and then some good ammo (Black Hills 77gr. match ammo and possibly the Prvi Partizan 75gr. match). You will also need a good scope as well. YMMV.

I'm tracking, I went to the 1st Mar Div and 2nd ID Sniper Courses. The Army one was for S&G at Camp Casey. We also used to run the A2 out to 600 yards while we were working the M-40 on the 1000 yard range.....I know the answer....I was just wishing for some kinda miracle to happen with ammo that I haven't worked with.

Anyone got a 20 inch 1/7 for rent?

I'm sending my daughter to summer camp (my version of a good summer camp) and I don't want her to lose her motivation when it comes to the 600 yard line. I won't be there so the SNCOs that are running it will be her only link.....

1/7 twist. I don't think LMT makes any 1/9 twist barrels

[Skter505]

You might be able to stabalize the 69 grain sierra in your 1/9. Work up some loads there's only one way to find out. Last I checked Bravo Co. Still had some of their stainless 16" barrels in stock if you feel the need for a new barrel.

Bravo! As the proud father of a 3-year-old girl who wants "a pink gun," I salute you.

Problem solved, I picked up a 6920 today.

It can be done

Aggunner,

I realize it can be done with a 16" and the right barrel/round combination. What rifle were you using?

[Aggunner]

Green one

Tracking; what is the barrel length and rifling?

[Aggunner]

18" 1:8 with a wylde chamber

Okay, that makes sense.

I was looking at my only rifle at the time of this thread starting (16.1" 1:9), I was pretty sure that it couldn't be done with a novice shooter.

I want to line my daughter up for success when she first starts to engage the target from 600 yards with iron sights. I bought the rifle that can do it today, I just need to get the right ammo now.

I got a 1X8" on my Carbine, and have used Hornady 75gr HPBT match ( magazine length ) and Hornady 75gr A-MAX and 80gr A-MAX single load, long range ammo and 600 yards with all of them is no problem.

With your 1X9" twist a 75/77gr HPBT may shoot OK in it but the 68/69gr HPBT class will do better, I know for a fact that they do OK out of a 20" barrel with a 1X10" twist out to 600 yards.

The .223 Rem/5.56X45mm NATO can do well out of a 20" barrel with the right bullet ( high Ballistic Coefficient bullet, like Hornady's 75gr A-MAX or 80gr A-MAX or a Burger 80gr VLD or 90gr VLD ) all the way out to 1000 yards. I shoot in NRA Service Rifle, and have beat guys at the 1000 yard line that were shooting "F-Class" and "match" rifles, and when I didn't win still made a good showing, all with a NRA/CMP 20" barreled Service Rifle with iron sights.

A 68/69gr HPBT bullet out of the 16" barrel will only lose 100 to 150 fps, and it will be enough to get you down to 600 yard line, the accuracy might be a little off if you use iron sights, because of the shorter sight radius. Other then that it should be no problem, once you get your 600 yard "dope" put on it.

Also a few years back a kid come to a match with the only AR he had to check it out and see if it was a sport he would like, he shot a 16" Carbine the whole course, he didn't do to well; but it was because of his lack of marksmanship skills and not the rifle. Even that being said he still did OK for a "new guy" that never shot a match.

This is about where my daughter is, she has sent about 400 - 500 rounds down range to 200 meters.

I couldn't get a 20" but I did get her a 6920 this week. I'll take her to the range tomorrow and let her break it in with some Hornady 75 gr. She should do okay with a 1/7, fingers are crossed. She'll be using the same setup that the USMC Rifle Team uses............

They are shooting M4's? Free floated barrel? Carry handle sights?

Oh, my.
