View Full Version : Is it possible?
Have any of you guys taken the 7.62mm out to1000yds in a 16" barrel? If you did, what bullet did you use? I'm going to try my darndest or am i, just going to waste my time and $$, well at least i'll have fun trying :D. What is the farthest you've taken you gas gun and what barrel lenght do you have on it?
I've taken a 16" MWS with CL barrel out to 600 yards and had no problem hitting silhouette plates 90% of the time with NF 2.5-10X32 and 168 grain AMAX. I dropped down to 50% hits when we moved out to 700 yards.
I was 90% hits at 700 yards with a 20" REPR and NF F1 and factory 175 grain OTM. I was just under 50% hits at 900 yards with this set up.
FWIW, making 1000 yard hits with any .308 has just as much to do with the shooter (wind and range estimates) as the rifle, optics, or ammo. This is illustrated by my ability to ring steel at 1200 yards with my .338 LM since it is a laser for 600 yards.

One of our customers took his LMt to a course using 175 grn Gold Medal and was able to hold his own. I can't remember what groups he was getting, but they were very respectable.

I'm going to try like hell with my 18 inch.

Lowlight over at Snipershide has a GAP 16" and he says he can hit around 5 out of 10 @ 1000 yds
Looked for like 20 minutes til I remembered where I read it.

Ya, it's the most consistent rifle I have at 1000 yards... why on earth would think a 16" GAP 10 would be "consistent" at 1000 yards. If you buy one of these looking to make your mark at 1000 yards, you're smoking crack.
Can I shoot it at 1000, yes, do I, yes, needs 39MOA, and with that I am lucky to hit 5 out of 10 shots, especially being at sea level, with 10+ mph winds.
the 308 is an 800m cartridge, we shoot it farther because we are arrogant and we can, not because it is particularly effect at that range.
That first sentence is of his is sarcastic I believe. Hard to hear sentence tone over the internet lol
They rave about the GAP10 over @ SH and GAP in general
My instructor at GPS Defense used his personal gun (PoF .308) with a 14" barrel, Leupold scope and 175gr. match ammo and was able to hit steel plates at 800+.
I was hitting out to 864 (max.) with a 5.56 SPR type rifle in the course using a Leupold scope and Black Hills match ammo.
Holy cow, awesome feat IG....864yds is really pushing it, the wind must have not been in play at all.
Actually we had some wind all three days. Part of the course teaches you how to calculate range, wind, etc...
One guy in the class had never shot long distance before or with optics and he was consistently hitting on day 3. Day one started a little slow and then picked up quickly. On day 2 we were shooting out past 400 IIRC.
The instruction was top notch and well worth the price of admission.

I have but admit I wasn't very successful. The last time was 2 weeks ago, and it was just too gusty to get any consistency. I could use some better wind estimation skills but I suspect anyone would have trouble with wind from 15-25 thats gusty like a SOB. There are much better calibers for fighting wind....at 750 I had 2.1 mils of windage correction, and at 1k I had ~3mils. If the wind is steady it makes thing easier, and little to no wind even better.
Texas winds are notoriously tough to shoot in..esp. in East Texas.
If we are talking using the .308 cartridge to reach 1k, than there are just so much better options if you intend to primarily do that particular application...hints the reason why the Military guns don't switch to something like a .260 rem or 6.5 creedmoor. It cost more, prob. suffers a bit more than .308 in terminal ballistics, but it blows the doors off the .308 in terms of LR accuracy.
L129A1's w. 16" Rock 5R SST's have confirmed hits down range out to 1300yds...clearly the shooter plays hugely in this equation at that distance, but were talking s/a rifles here and thereby I would assume they launched a cpl. rds before making the mark.
There is a true story from IIrc a Canadian sniper in Astan that had a confirmed at something like 2k + and he was able to walk in like 2-3 shots until he dropped this particular bad guy. During the interview the sniper said the 2 Taliban fighters didn't even act like it bothered em until obviously one fell and never got up....eta...the caliber wasn't .308 it was .338 just to be clear.
So it is possible to hit 1k with a16" gas gun, just take persistence and patience and alittle luck. I'm thinking 168gr A-Max or the 175gr MatchKing. I've got a 1-10 inch twist in my pipe. Might even try LAPUA 155 Scenar but at $45-$50 that a lot for playing around. Thank guy :cool:. I feel better now!!

Awesome.
Coming from a guy that shortened barrels on his rifles 30+ years ago, and took crap from a lot of the "experts" for doing so, makes me happy to hear about that kind of short barrel shooting.

Its definately possible. Is it worthwhile? The 308 round period isn't a ideal round for 1000 meters. BC isn't as high, velocitys drop past 800. That being said, its definately easier in a bolt gun to reach that with the 18 inch barrel. How much so is relative because with an 18 inch barrel the difference in velocitys of bolt and gas is not that much.
I remember reading a thread that mentioned Chris Costa shooting a 16" SR25 EMC at a class and getting hits out to 1,643 yards. While not ideal, it certainly goes to show what's possible. I don't know any details, just passing on what I read. I'll try to dig the page up.

The rifle/barrel/twist combination was designed for 800/850 yards and met the army requirements of hitting targets 90% of the time during trials.
It has since met these requirements in the field as well.
However, there are now several cases of documented hits at 950+ yards.
At these ranges, with a 16" barrel, the bullet is coming in from a very high angle. If you want to go for the longer ranges, use an 18" barrel as you will get a little more velocity and greater stabilisation. You might also consider a faster twist (such as 1-10") if you intend to use heavier projectiles.
The 20" match barrel does make a good 1,000 yd gun.
