Can You Shoot 1,000 Yards with a .308 caliber AR-15 style
rifle? Well, can you? Conventional wisdom says no. After all, AR’s are
semi-automatic designs, with hot burning gas of doom smothering all the
important parts like gravy over Cracker Barrel’s Chicken Fried Chicken.
Heck, the upper and lower receivers are stuck together with simple push
pins. AR-type rifles can’t be all that accurate, can they?
To find out, the folks from
Smith & Wesson,
NRA Outdoors,
Sub-MOA Firearms,
Hornady,
Huskemaw Optics,
Magpul,
Blackhawk!,
Battenfeld,
Champion,
SportEar, and
Brownells put together a long range shooting school. The rifle of choice?
Smith & Wesson’s M&P 10 LE .308.
The baker’s dozen of identical guns present were off-the-rack models
with no customization other than the addition of a Magpul PRS Precision
Adjustable Stock. These were added just so each shooter could customize
the length of pull and comb height. AFor optics, all rifles were
equipped with Huskemaw Optics 3-12×42 with RFBC Custom Turrets. If you
send specific data on the load, rifle, actual velocity and average
atmospheric conditions for your area, they’ll print a custom turret with
yardages and wind holds marked.
See that shrub out there? That’s the 1,000 yard target berm.
A Smith & Wesson M&P 10 LE Model facing targets at 400, 500, 600, 700, 800, 900 and 1,000 targets down range.
Even the Smith & Wesson folks didn’t quite know what to expect
from this outing. Sure, they’ve tested the M&P 10 at ranges
appropriate for the intended use. It would be hard to imagine the LE
model being used in the field for shots over 200 yards. Of course, these
rifles have been tested for accuracy at 100, 200 and 300-yard ranges.
They were fairly confident we’d be able to reach out to 800 yards with
some success, considering the design of the rifle and ballistic profile
of the 168 grain .308 round, but even that wasn’t a sure thing.
Over two days, our instructors taught theory, technique, position and
lots of math, which enabled us to nail consistently targets at long
distance. On day one, we started shooting in a structured environment –
the SubMOA Firearms range. It’s got a beautiful shoot house on a
mountain peak, equipped with benches, Caldwell Flite Control Front Rests
and a passel of Swarovski spotting scopes.
Smith
& Wesson designed their own flash hider for the M&P 10 LE. It’s
intended to suppress both primary and secondary flash. It’s also got
ports that provide muzzle brake function.
A
high-quality spotting scope makes all the difference. When you need to
read wind 1,000 yards out, it helps to be able to clearly see blades of
grass. This Swarovski model fit the bill.
The SubMOA range stretches 1,000 yards towards 9,000-foot high
natural backstops. None the less, some insurance genius made them
install 12-foot high berms at each target area. Based on the volume of
continuous gunfire, the neighbors have taken to calling this area Little
Beirut. Once the shooting started, I completely understood that.
On day one, we used the stable shooting positions and predictable
ranges to develop dope books for our individual rifles and the Hornady
.308 168 grain A-Max load. Starting at 400 yards, which was easy, we
quickly stretched out to 500, 600, 700 and then 800 yards to capture
exact elevation adjustments required to get on target given the current
atmospheric conditions.
On day two, we moved to more scenic and natural environments. These two targets were 650 and 775 yards away.
While it looks close through the Swarovski spotting scope, these targets are 400 yards down range.
The wind was fairly calm in the morning but got interesting in the
afternoon. At times, it was blowing 15 to 17 in our face. That was
broken up by occasional left to right and right to left shifts. The
90-degree wind vector rarely exceeded five mph, so it was a good day to
test the capabilities of the rifles. Even with the relatively light
crosswinds, it quickly became apparent that the biggest variable in long
range success is accurate reading and doping for the wind.
The Smith & Wesson M&P 10 at 1,000 Yards
Once we got the hang of shooting the 800-yard target from the bench,
we decided to stretch things all the way out to 1,000 yards. The 168
grain .308 is not the ideal 1,000-yard cartridge, but with a consistent
load and accurate gun, it’s completely doable.
Just to put things in perspective at what happened to our Hornady 168
grain A-Max bullets, consider this. At 1,000 yards, the bullet drop is a
whopping 353 inches. That’s 5.19117 Ryan Seacrest’s stacked on top of
each other, but we can just round down to five since he’s not easily
divisible. Flight time was 1.77 seconds. That was more than enough time
to recover from recoil, leisurely require the target, and still wait to
watch the impact. That’s pretty darn cool.
Once we got the wind figured out results were surprisingly
repeatable. Initially, we shot from a solid shooting bench with a front
rest and a rear sand bag supporting the stock. As expected, this was a
solid position, and we were able to knock the 15-inch square steel plate
with ease. The only reason for misses was bad wind calls. See what I
did there? I just blamed my spotter!
Here’s
our 1,000 yard target. My shooter/spotter partner and I plugged this
15-inch square target pretty good from 1,000 yards. I’m claiming the one
in the center.
We did a lot of prone position shooting using this Blackhawk! Pro-Shooters Mat. It made all the difference on rocky terrain.
Next, we moved to prone and sitting positions, still working the
1,000 yard, 15-inch steel plates. For prone, we attached Caldwell AR
Bipods to the front Magpul rail, dropped into position on a Blackhawk!
Pro Shooters Mat and got busy. Even applying lots of forward pressure on
the bipods for stability, we experienced the same accuracy as from the
bench. Keep in mind that the hand guard on this rifle is not free
floated, so we thought we might find significant point of impact
variance. While we didn’t do scientific group testing to identify a
small point of impact shift, we were still hitting that small plate at
1,000 yards with the same dope. If there was any point of impact change,
it wasn’t significant.
Next, we moved to a sitting position using Double Crossed Shooting
Sticks. Like regular sticks, there are only two points of contact with
the ground, but they are split, so there is support at the front and
rear of the rifle. Your body serves as an additional ground contact
point. Once I got settled, I hit three in a row from a sitting position
using the sticks. Yes, shooting sticks. Our NRA Outdoor instruction team
knew their long range shooting techniques and taught me an incredibly
stable way to use these supports. I know you professional snipers out
there can do this with one leg tied behind your back, but for a regular
shooter guy like me, I was blown away at this kind of result.
Note
the Double Crossed shooting sticks being used by my shooter/spotter
partner. He’s got an incredibly stable hold from a field sitting
position. That’s our instructor Dusty on the spotting scope.
Just a few of the rifles used. They’re all stock models, with the exception of the Magpul PRS Precision-Adjustable Stocks.
We got consistent results until the barrel heated up. But come on!
The Smith & Wesson M&P 10 LE is a pencil barrel rifle, so that’s
gonna happen. While I didn’t do scientific testing, it appeared that
accuracy stayed consistent for somewhere between 10 and 20 shots in
close proximity. Then, if shooting at extreme distance, you’d want to
let it cool down for a few minutes. At shorter ranges of less than 400
yards, this overheating would be largely irrelevant. That’s absolutely
consistent with the original design goals of this rifle.
Over ¾ of a Mile?
After hitting 1,000 targets with regularity using the Smith &
Wesson M&P 10 LE, we got bored and decided to stretch things out a
bit more. Just for kicks, we took aim at some large rocks in a sand pit
1,400 yards down range. That’s .8 miles. The sand pit made it easier to
spot impacts while we got the range dialed in.
Note the fully ambidextrous controls on the M&P 10 LE.
I lost count after 57 billion rounds of Hornady .308 ammo sent down range.
The first challenge to overcome was that the trajectory of the .308
round at that distance exceeded the scopes ability to adjust, even using
full elevation adjustment and adding holdover with the reticle.
Fortunately, a number of the rifles were equipped with some new RAMP
mounts from Warne. These have a 20 minute of angle adjustment built in,
so the scopes we were using could be adjusted a full 60 minutes of angle
in elevation. When using an angled mount, you adjust the scope’s zero
much higher in the scopes vertical adjustment range, allowing more
elevation adjustment. Our reticle had vertical hash marks at 2, 4, 8 and
10 minutes of angle, so we had wiggle room around our estimated
requirement of 65 minutes of angle elevation required. Yep, we had to
use all available scope adjustment, plus holdover to get on target.
The barrel on the Smith M&P 10 LE is not free-floated, yet applying lots of pressure to the bipod didn’t seem to matter.
A new trial for me was the Huskemaw Optics. We used 3-12×42, and that was plenty of magnification to reach 1,000 yards.
65 minutes at 1,400 yards is one heckuva drop. That’s about 946.4
inches, or 14.339 Ryan Seacrest’s. Put another way, the vertical drop is
nearly 2 ½ of those scary high dives your childhood friends dared you
to jump from. While falling from the high dive might have seemed an
eternity, the flight time of the Hornady 168 grain .308 projectile was
even longer. We calculated that the bullet was in the air for 2.54
seconds, give or take. While I didn’t time it, I figured it took about a
week for the sound of a hit to travel back to the firing line.
While I wouldn’t want to trust my life to a first shot hit in this
scenario at 1,400 yards, we managed to get on target and could reliably
put bullets in the vicinity of a few feet. I did notice that Hornady
Marketing head Neal Emery dipped into his secret stash of 175-grain
rounds and was having even better success at the 1,400-yard game. It
pays to have connections, right?
One of the upgrades on the M&P 10 LE model is the Magpul hand guard.
The Magpul PRS Precision-Adjustable Stock allows adjustment of length of pull and comb height.
Shocked Face
Consider me shocked. I wouldn’t have expected to be able to make
consistent and repeatable hits from 1,000 yards with a stock AR-10.
Certainly, those results stem from a combination of quality gun, great
ammo, and most importantly excellent long range shooting instruction. If
you’re interested in learning long range shooting techniques, keep an
eye on the
NRA Outdoors website.
While the current classes are out west, they’re opening up additional
ones on the east coast, so matter where you live, classes will be within
range. See what I did there?
