Most long range shooters, and the military LR118 ammo is a 175 grain bullet to help keep the round sonic and improve ToF and ballistics at range. The fact remains the only reason why the military uses the .308 is because they have metric ass-tons of it in storage. The same reason why we stuck with 5.56 and the same reason why we stuck with .30-06 in WWII, etc.

The .308 is less than ideal at 1000 yards. It's slow, susceptible to wind, and it makes range calculations even more important (and likely to be screwed up).

That's a lot of luck and probably no wind.

The world record in benchrest shooting at 1000 yards is around the 4" mark with a gun purposely built for accuracy without human interaction in 10 rounds.

Range finding and wind calls count far more than equipment. At 500 yards a dead body could make hits with a .308 ... but move out to 750 and 1000 and the game changes drastically.

My girlfriend made 3 hits in a row at 1000 yards on a 1 MOA target with my TRG42 in .338, having never fired a long range precision bolt-rifle. The round is a game changer at 1000 yards since it's so flat and wind resistant.

Definitely, it's a great round. Low recoil, easy to reload, easy to find, available in a million platforms. Kills **** all good like. What's not to love?

Speaking of which, I need to trade up from 168gr to 175/190gr for my next loads. The 168gr were great for ranges under 400 yards but they're coming unhinged at 500. Lots of folks at the range (and online) have said the heavier bullets hold their stability longer. Is that really due to weight or a longer axis?

[Spider Pig]

Well, you're not going to have a much longer axis from 168 to 175. To 190, it is going to increase more, but it's the weight of the bullet that keeps it steadier over distance and with wind.

[RallyNavvie]

It's my aeronautical background with physics that's making me think increasing long axis helps with stability. Although I never dealt with supersonic physics. Does it have something to do with the increased rotational mass overcoming the effects of drag over long distances?

The 175 has a higher BC and the added benefit of greater inertia.

A number of guns over-stabilize the 168s as well ... a 1:10 gun is better suited for 175+ whereas a 1:12 is better suited (typically) with 147 - 168 grainers.

I am buying a new upper soon. Will be selling a LMT 14.5" upper with a KAC RAS. Where is the best place to sell such a thing?

[Spider Pig]

A gun show. Or Gunbroker. You're not really going to get anything decent for it at a gun shop.

[mightymints]

Ok. Well anyways, I got a Daniel defense upper with 14.5" barrel. Daniel defense mk18 m4 ris II. Battlecomp, acog, peq15 etc.

[Spider Pig]

Speaking of barrels, does anyone have any experience with carbon fiber ones? I have a client that wants one, but I've heard that they tend to delaminate pretty quickly and they're not worth the price for a small weight savings.

The only company I know that still makes them for AR15s is Christensen Arms. I know Jense Precision used to make them, but I can't find anymore info about them.

[Subaru_Freak]

I think they are cool, but not something I'd invest into Spider.

[Spider Pig]

Yeah, that's what I told my customer. I think he just wants the baddest AR at the range. I've thrown on a gas piston system, two stage trigger, and a ton of other stuff already.

He just has his mind set on one, but I don't want the heat that the piston system throws off onto the outside of the barrel to destroy the finish of the carbon fiber, which I'm pretty sure will happen.

[Subaru_Freak]

As long as you are upfront with it's limitations, sell him one.

[bigdanswrx]

what do you hunt? where do you hunt? i go out with my brother and we do some hog hunting and duck hunting.

What do you want for it? Does it come with the carrier group? F/A carrier?

I hunt a variety of paper, metal, and exploding targets.

[RallyNavvie]

If someone hunts pigs at 500+ yards please let me know. I think it might be fun to get some practice with the rest of the gear (rangefinder, spotting scope, etc.).

In most places in Central Texas it's hard to get a shot that long.

That being said, just make a dope chart and learn to use Mils. Shoulder height on a pig doesn't really change that much, wouldn't be hard to use a hold-over.

Set your zero at 200 - 250 yards and you'll have a very flexible range.

That or shoot a .338 Lapua Mag and laugh at the pigs as they explode.

[Spider Pig]

Yeah, 500 yard pig hunting in north Texas isn't really going to happen either. The max I've hunted hogs at is around 150, and that's mostly because they tend to stick to the woods and treeline. They know we're here to kill them.

When they infest my parent's ranch, we usually set up a feeder about 100 yards away from a pile of round hay bales, and I shoot 308 from on top of those using a Kill Light.

It's worked well so far.

I assume they're like most animals and pay no attention to you at longer ranges. Even on my family's farms in northern Wisconsin there are fields that would offer a 300-400 yard shot and the deer wouldn't even notice you fumbling up into your stand.

[Spider Pig]

Hogs can get pretty stupid. If they can't see you, they don't really move. And that includes when you drop the one right next to where they're standing. They tend to just sort of scoot around in a small circle and then stand still waiting to get dropped.

So if they can't see or smell you, you're golden.

[mightymints]

Ok change of plan for me. I am going to get a KAC URX III

[TyrannoSullyRex]

[Decon]

Well I finally got my self a pistol. Sig p226 tactical operation 9mm. 4 20rd mags siglite rear night sights and truglo tritium fiber optic front sight. Its my first real pistol, and only got to shot it once so far. But to me it handles awsome and fits my hands perfect.

[mightymints]

Anyone in Austin who can remove my AR15 barrel?

[aggie113]

Got a Magpul mag in for my DPMS AR 10 and I must say it is much easier to load up than both the original and aftermarket metal mags I have. I can also actually load 20 rounds vs the 19 of the others. On top of that it's cheap, too bad I already have around 10 of the metal ones
Also installed some KNS hammer/trigger pins, the originals kept walking out ever since I got the Timney stage 2 trigger.
Now just waiting on the always backstocked ACS-L buttstock to arrive...

FYI, kick ass 1911's are up for grap at a kick ass charity raffle:
