Longest you've lobbed a 5.56 Gas Gun?

[redneckbmxer24]

I lobbed a bunch at a mile with an 18” and 77gr black hills one time and consistently hit the ground 100% of the shots. Does that count? Not one of the 50 rounds fired hit the 3’ target but there was a lot of dust being kicked up in about a 20’ radius.

600 yards is pretty much the max for me using an SPR with 77’s and getting consistent hits. I’ve pushed them much further with decent hit ratios, but that’s where I see performance start to go down hill pretty rapidly. Out to 600 I can get a first round hit about 90% of the time on a 2moa target.

I'm shooting a Douglas 1/7 spr.

My magnetospeed is only reading 2670's with my bh 77, fc262 and cbc 262?

Think my chrono is off?

I'd check because I'm getting 2640 with a 77 TMK out of a 16" Mk12 Mod Holland

 

[Shoots 700's]

We shoot 18 ar with 77’s and it’s not an issue to hit 600 plus

 

[deersniper]

I think that pivot is going to catch a miss or richochet.

 

[Subwrx300]

On a 16"x 20" torso with an 18" barrel, 69TMKs were consistent 90% hits in mild wind at 600, 80% at 700 and consistent misses with occasional hits (~10%) at 1060.

Tossed some rounds at 1760 but I saw zero signs that I was even in the ball park. I might just as well have been using a 22LR subsonic, it was futile. I'll never get those 20 rounds back....?.

 

[Pbjunkiee]

HAHAHA, yup we are all in the same boat it sounds like.

Glad to hear us 5.56 guys are suffering together.

 

[deersniper]

Hit a baby fox at 550 first shot leaning on a fence post with a 16" POF shooting 60gr vmax either BH or Hornady.
Seems to fall apart past 600. Hornady superperformance extends the range but it isn't recommended for gas guns.

 

[XTR]

HP Shooters take them to 600 all the time using 20" barrels, and in a sling and coat with no support, and irons or a 4x optic it's pretty common to 10 to 15 out of 20 in the 12" ten ring.

Really good guys shoot better, the rest of it's closer to 5 out of 20 in the ten ring.

 

[Subwrx300]

HAHAHA, yup we are all in the same boat it sounds like.

Glad to hear us 5.56 guys are suffering together.

Yup. So I built a 224V to solve the 800-1100yard varmint problem. Works awesome! Was super skeptical at first but it's proved itself out for my application and now I have very little need for a 223 unless inside 500 and want a super light gun with min optics.

 

[rybe390]

I’ve taken my 16” out to 1,040 yards with some decent success. The wind was howling pretty bad too. Ideally I’d keep it 800 and in with a 5.56.

 

[Shoots 700's]

We keep joking that we are asking what some consider a 300-400 yard battle rifle and try to make it into something it’s not.

But we have fun pushing it as far as we can.

 

[RyanScott]

I know too many people who have had success at long range in combat with the Mk12 or M4 to call it a 400m gun. The former includes two guys with numerous dead Taliban between them at 800M or more and the latter includes a Guard LTC who killed a Taliban that was out in the open at 600 yards not realizing that the ANP on the other hillside had an American advisor with them.

If the M16 is a 400m gun the M14 is also...

 

[whatsupdoc]

Tried some long range gas gun shooting today. 22" kreiger bull, CLE chamber, Magtech 77 otm @ 2910.
12" steel @ 653 yards 90%, 16" steel @ 779 yards 70%. Tried 1000 yards but could not see the dirt splashes or hits need a spotter.
I had a blast and no reloading when I get home.

 

[VegasHKShooter]

850 yds in Vegas. That’s 9.3 mils shooting a Speer 75gr Gold Dot. Don’t remember if it was a 16” or 18” barrel. Was a pretty calm day. I think 1 mil of wind. Scope was NF 1-8.

 

[drewdru1]

My furthest was about 15 feet. Had been fighting issues all day. Finally gave up

 

[sandwarrior]

One day when conditions were stable, I was getting 69 gr. SMK's to go consistently onto a 10-15" plate out of my scoped A3. Conditions changed and it seemed like i couldn't find the groove again for a while. Too much drift to easily call the wind. Changes in atmosphere make a huge difference in .22 cal cartridges, as I also noticed what I call one day under a given temp/alt. is very different from the next time I go out. More change it seems than either 6.5mm or 7mm.

 

[Khavic]

24" 1-8tw pushing 77gr TMK with 6-24X50 Vortex from prone I've managed 70% hits for ten rounds on 75% IPSC steel at 980yds. Wind changed and that was the end of that. Usually ran around the 50% margin on that target, but I struggle to tune a gas gun load like I can a bolt gun load.

 

[Kopfjager1]

I've taken my 16" Rainier Arms Ultramatch, NF 2.5-10x24, shooting IMI Mk 262 to a 1000 a few times. I had a large vertical spread during the winter, but these past few months, ESs have been a lot better (30 fps versus 70 during the winter), getting 3-4 impacts of 5 rounds fired on a 66% IPSC at 990 yards.

However, my capability and confidence says to stay within 700 to have precise impacts.

 

[Unknown]

Lots would depend on bullet weight, and muzzle velocity. We used to have a guy show up at our 600 yard shoots with some unusual cartridge that shot a 224 diameter bullet. I was scoring his target, and as his bullets went overhead and through his target, about a third of them didn't have the sonic crack of all the other bullets. Of the third of bullets that appeared to be subsonic, about half of those would make slightly oblong holes through the target. The subsonic bullets didn't show a complete keyhole like a bullet hitting the target sideways, but they were most definitely beginning to yaw to the side. Even those that were subsonic hit the backer, but for that cartridge, I'll bet that another 50 yards of distance would have been enough so that he would have had trouble hitting an IPSC target. He was shooting a light weight 224 bullet around 50 grains..

It would be easy to crunch the numbers on a ballistics program to find out at which distance the bullets begin to go transonic.

 

[Peterpan]

With my 69 gr smk reloads and a 24 inch barrel I can get to 1000 yards fairly easily on a 2 foot by 2 foot plate as long as there is little to no wind or a constant low mph wind. Wind is the kicker every time for any consistency

 

[Rudy Gonsior]

Longest I've ever pushed a 5.56 was a little over a mile, using Mk262 MOD 1 out of a Mk12 MOD 1. Long and short of it was I had a bit of time one afternoon in Afghanistan and wanted to push it. This particular Mk12 was legendary as accuracy goes, a legit 1/4 MOA, by far the best shooting gas-gun I've ever had my hands on. From 0 to 600m it was a one shot, stop rifle as bad guys are concerned, even in some pretty hellish conditions of 18-20 mph winds, I was able to connect with solid center mass hits. 600m to 800m I could pretty much guarantee hits in good conditions, only question was how long it'd take for them to bleed out. At 800m to 1200ish it ranged from about 50% hit rates to being able to professionally scare the shit out of bad guys.

Anyhow I'd say at our altitude (7,000-9,000ft) while pushing the 77 SMKs at 2900ish, it could easily hold 2 MOA at 1000m with some regularity under ideal conditions once the wind was figured out. Of course the wind is main problem with 5.56 at those distances, a butterfly farts and you are off one edge or the other, but if you can catch your splash and your fast on the gun then hits on man sized targets are quite possible.

As for lobbing 5.56 at a mile, it was mainly for the fun of it. My partner and I started on a bolder that was maybe 3-4 MOA at 1540m, wind was maybe 0-2 mph down low and after a little right and left we trued up on the 1540m rock. Wanting to see how far we could go and with time and ammo to burn, we lased a rock face halfway up a mountain at about 1700m. The first 4-5 shots were unobserved, then finally my spotter caught a little puff off the bottom and tried corrected me on. The problem was the vertical spread was at least 4 MOA, never chron'd the gun but I'm guessing SD's somewheres between 10-20 FPS. And of course the wind, even in great conditions, even being fast on the gun just wasn't fast enough with those long TOF all the way across the valley. We'd land 2 or 3 rounds on the rock face in a 4 MOA group, then send one unobserved off the rock face. We fired a total of maybe about 30 rounds and called it good.

In all we had a good time lobbing rounds, but it was certainly interesting and gave us an appreciation for what that system could and couldn't do. For kicks, I'd like to try it again someday but with better round and a more suitable location. I'm not sure the results would be astronomically better but I think cleaning up the SD's and having a nice big back drop would make it easier.

Added: @ 1k Never successfully hit pas that.

 

[RTH1800]

I am confident to 600 m in less than 10 MPH winds. Beyond that I am not expecting a high rate of success.

 

[MrPaul]

4.5" clays laying on the berm at 600 about 50%. Long walk to set up more and I'm lazy so we just shoot the pieces into smaller pieces. Hit ratio goes way down as pieces get smaller.
