.375 CheyTac — K02M-Winning, World-Beating Cartridge

Derek Rodgers is the 2017 King of 2 Miles. He is also the only human to ever hit the maximum distance target target at 3368 yards (1.91 miles). His cartridge choice? The .375 CheyTac. Derek ran Cutting Edge Bullets in Peterson brass with Hodgdon H50BMG powder.

Q: Why did you choose the .375 CheyTac cartridge?

Derek: When I was asked to join the Applied Ballistics Team, I needed to get an ELR rifle built in a short period of time. I was under a very tight time schedule to get the project complete. In an effort to eliminate variables, I decided to keep things standard and as simple as possible. I chose the .375 CheyTac for the ease of getting components. The larger rifles are more difficult to get components quickly and I felt like the .375 CheyTac had enough attributes to be competitive at ELR distances.

Big Rig — .338 Lapua Magnum Improved for King of 2 Miles Match


Click Image above for full-screen version

There’s a talented new team getting ready for the 2017 King of 2 Miles (KO2M) Competition in Raton, NM next month. The team features ace F-Class shooters Ian Klemm and Dan Pohlabel. Here’s a build report from X-Treme Shooting Products, which supplied the impressive XTSP action and two-stage trigger.

Big Gun for King of 2 Miles Event at Raton
XTSP: “It’s exciting — we’re getting closer to the 2017 King of 2 Miles match next month. Here are a few pictures of one of the rifles we will be shooting. Owned and built by Dan Pohlabel, it’s a .338 Lapua Magnum Improved. It has a 40° shoulder and we plan on shooting .338 Caliber 300 grain Berger OTM projectiles at around 3,100 fps.”

XTSP X-Treme Shooting Products .338 Lapua Magnum Improved king 2 miles ELR

“We started off with an XTSP .338 Magnum receiver, custom-built as a single shot with a solid bottom for stiffness. We built +60 MOA rails for each of the rifles. Of course we’re using the XTSP two-stage trigger! We added a 34″-long Bartlein gain-twist barrel which is 1.450″ at the shank tapering to 1.2″ at the muzzle. At the end we added Piercision Rifles’ 3/4 x 24 slabbed 5-Port ‘Muscle Brake’. The action is bedded in a McMillan Super Magnum stock. On top sits a Vortex Optics HD Razor in Vortex 35mm rings. We’ll have another rifle just like it shortly with the machine work by Dan Pohlabel again. That second rifle will be finished up and shot by Ian Klemm of Vortex Optics.”

Your Worst Nightmare: Catastrophic .338 Lapua Magnum Kaboom

Kaboom Manatee Savage .338 LM, Lapua Magnum, catastrophic, explosion, cleaning rod, obstruction
Click to zoom image

We first ran this story a couple years back. We’re republishing it today as a reminder to our readers that safety should be their paramount concern at the range. Avoid distractions and always check your barrel for obstructions before you chamber a round or pull the trigger. A moment of inattention can result in a catastrophic kaboom …

Discharging a .338 Lapua Magnum round with a cleaning rod in the barrel — that’s a recipe for disaster. What happens when a fired .338 caliber bullet and a cleaning rod try to occupy the same place at the same time? Well you get a catastrophic kaboom, with metal pieces flying all over the place, and a shooter very lucky to escape without serious injury. This incident occurred recently in Manatee, Florida, as reported by Sniper’s Hide member Queequeg. We thank SnipersHide.com for granting permission to publish these revealing images in the Daily Bulletin. CLICK HERE for more Kaboom info on the ‘Hide.

Kaboom Manatee Savage .338 LM, Lapua Magnum, catastrophic, explosion, cleaning rod, obstruction

This story should serve as a chilling reminder to follow proper safety practices whenever you are at the range. Always check to make sure there is no obstruction in the bore BEFORE loading a live round.

.338 Lapua Magnum + Cleaning Rod + Inattention = Kaboom!

Kaboom at Manatee!
Sniper’s Hide member Queequeg recently published shocking photos of a catastrophic kaboom involving a .338 Lapua Magnum (Savage action). The action was blown off the rifle, shrapnel went through the roof, and the barrel split at the tenon before taking an excursion downrange. The action did crack in the front but the lugs remained engaged so the bolt did not slam to the rear (luckily for the shooter).

Here’s the report: “This happened [January 20, 2014] at the Manatee Gun and Archery Club. Al, Ren and myself were there with a couple other folks. Ren was at bench 12, I was at 13. The fellow at 11 was running a Savage .338 Lapua. He had a very bad day! He damn sure could have killed himself and quite likely Ren as well.”

Kaboom Manatee Savage .338 LM, Lapua Magnum, catastrophic, explosion, cleaning rod, obstruction

Queeqeg added: “After the boom, I heard Ren ask ‘Are you alright’ and then turned to look in time to see the fellow reacting in total shock — literally stunned. Ren and I went over to him and could not see any major injuries. Ren was uninjured as well but had a lot of fiberglass splinters on him. The barrel nut is what I presume punched the two holes in the roof. The shooter is a regular there[.] He had been having a problem with sticky cases though he said he was certain the loads were mild. That’s why he was content to knock the sticky ones out with the rod. He simply forgot to remove the rod after knocking out the last stuck case. You can see what happened next.”

To learn more about this incident, go to the original Snipers Hide Forum Thread. There you’ll find more details and over four pages of related discussions.

The Important Lesson Here
What did the .338 LM shooter do wrong here? You will say — “Well that’s obvious, he left a cleaning rod in the barrel and then shot a round.” Yes, that was a potentially fatal error. But that was his second mistake — one that occurred only because he made a more fundamental judgment error first.

The FIRST mistake was not acknowledging the problem with his ammo. Had he heeded the warning signs, he would still have a rifle (and an unsoiled pair of trousers). When he first observed that he was having problems with extracting cases, a warning light should have gone off in his head. Presuming his extractor was not broken (and that the chamber was cut properly) he should have been able to extract his brass if he was running safe loads. The lesson here we all need to learn is that if you observe a serious ammo-related issue, it is time to stop shooting. Don’t try to invent work-arounds just to extend your range session, when there are clear signs that something is wrong, very wrong.

Extreme Long Range — .338 Lapua Magnum at 2160 Yards

2160 yards 1.3 miles long range ELR .338 Lapua Magnum Ed Connors Speeded Gonzales
Ed Connors placed three consecutive shots all on target at 2160 yards for a sub-3/8 MOA group. Wow.

Amazing shooting — that’s how we’d describe what Ed Connors accomplished recently with his Speedy-built .338 Lapua Magnum LR rifle. Ed nailed a 3-shot group at 2160 yards that would be great at 1000 yards. Check out the target above. Now consider that the shooter was a full mile PLUS 400 yards away. That is truly remarkable accuracy.

At this distance, 2160 yards, one MOA is 22.61″. This three-consecutive-shot group, measuring about 8 inches, works out to less than 3/8 MOA. Think about that — most guys would be elated to shoot 3/8 MOA at two hundred yards. Ed did that at over two thousand yards!

That takes a great rifle, as well as great ammo. Ed says: “I believe in loading like a benchrest shooter to achieve these ultra long-range shots”.

Gunsmith Thomas “Speedy” Gonzalez writes: “Anytime you build a customer a rifle to work out beyond the 1000-yard mark you must work hand-in-hand with your customer and explain everything you are doing to ensure performance at distances most shooters never even contemplate (except in their dreams).

Ed was involved in all aspects of the projects from the reamer print to what we needed for both single-shot work and mag-fed function in timed competition. This was Ed’s very first work-out with his reborn Surgeon-actioned .338 Lapua Magnum. He did great to say the least!”

Pretty Darn Good at One Mile as Well…
While “tuning up” for his 2160-yard session. Ed also produced some very impressive results at one mile (1760 yards). Once he got “dialed in” he delivered three shots you can cover with the palm of your hand. That’s spectacular consistency at one mile.

.338 Lapua Magnum Barrel Cut-Down Velocity Test

.338 Lapua Magnum LM barrel length vs velocity cut down test chrono rifleshooter.com
Shooters contemplating purchase of a .338 LM rifle often ask: “What length barrel should I get?” Rifleshooter.com recently performed a test that provides interesting answers…

Our friends at RifleShooter.com like to slice and dice — barrels that is. They have done barrel length cut-down tests for popular calibers like the .223 Rem, 6.5 Creedmoor, and .308 Winchester. But now they’ve tackled something way bigger — the .338 Lapua Magnum, a true “Big Boomer”. Starting with a beefy 30″-long Pac-Nor Barrel, RifleShooter.com chopped the tube down in one-inch increments all the way down to 17 inches (that’s 14 different lengths). At each new (shorter) barrel length, velocity was measured with a MagnetoSpeed chronograph using two different loads, 250gr SMKs with H4831sc and 300gr SMKs with Retumbo. Four shots were fired at each length with each load, a total of 112 rounds.

Load #1: 250gr Sierra MK, Lapua brass, CCI #250 primer, H4831SC, OAL 3.720″.
Load #2: 300gr Sierra MK, Lapua brass, Win WLRM primer, Retumbo, OAL 3.720″.

The .338 Lapua Magnum is a jumbo-sized cartridge, that’s for sure…

Donor Barrel Sacrificed for Science
Rifleshooter.com’s Editor explains: “Brandon from Precision Addiction offered to send us his .338 barrel for our .338 Lapua Mag test. I took him up on his offer and he sent me his used Pac-Nor chrome-moly barrel with about 600 rounds though it. This thing was a beast! A heavy 1.350″ shank that ran straight for 6″, until tapering to 1″ at 30″ in length.”

.338 Lapua Magnum LM barrel length vs velocity cut down test chrono rifleshooter.com

Results Summary

.338 Lapua Magnum with 250gr Sierra MatchKings
After shortening the barrel from 30″ to 17″, total velocity reduction for the 250-grainers was 395 FPS, an average loss of 30.4 FPS per 1″ cut. The amount of velocity loss per inch rose as the barrel got shorter, with the biggest speed reduction, a loss of 55 FPS, coming with the cut from 18″ to 17″.

Start Velocity: 2942 FPS | End Velocity: 2547 FPS | Average Loss Per Inch: 30.4 FPS

.338 Lapua Magnum with 300gr Sierra MatchKings
Shooting the 300-grainers, total velocity reduction was 341 fps, an average of 26.2 FPS loss per 1″ cut (30″ down to 17″). However, the speed actually increased with the first cut from 30 inches to 29 inches. The tester noted: “The 300 SMK load showed a slight increase from 30″ to 29″. I’ve recorded this in other tests and it seems to be more common with a heavier load. I suspect it is primarily due to the small sample sizes being used along with the relative proximity of muzzle velocities in adjacent lengths.”

Start Velocity: 2833 FPS | End Velocity: 2492 FPS | Average Loss Per Inch: 26.2 FPS*

*Velocity rose with first cut. Velocities ranged from 2,871 FPS (29″) to 2,492 FPS (17″) for a total velocity loss of 341 FPS.

RifleShooter.com crunched the velocity numbers in some interesting ways. For example they analyzed rate of velocity loss, concluding that: “after the initial rate change, the rate of the change in velocity is fairly consistent.” (View Rate of Change Graph)

How Velocity Loss Alters Long-Range Ballistics
The testers wanted to determine how the velocity reductions “affect our ability to hit targets downrange”. So, Rifleshooter.com plotted changes in elevation and wind drift at all barrel lengths. This revealed something interesting — drift increased significantly below 26″ barrel length: “Above 26″ things look pretty good, below 22″ they change quickly.”

We highly recommend you read the whole story. Rifleshooter.com put in serious time and effort, resulting in solid, thought-provoking results. The data is presented in multiple tables and graphs, revealing inch-by-inch velocities, change “deltas”, and SDs at each length.

Norway Adventure with .338 Lapua Magnum

Norway Fjord .338 Lapua Magnum Norma Blaser R8 Zeiss

As a holiday treat for our readers, we are reprising a video feature about hunting in Norway. After watching this video, you may want to head off to Vesterålen in northern Norway…

This is one of the finest shooting videos we’ve ever seen. Set in the scenic Vesterålen archipelago of northern Norway, this high-quality 15-minute video is part Nat Geo travelog, part ballistics lesson, part gear review. We wish we had the opportunity to join Ulf Lindroth and Thomas Haugland on their remarkable shooting adventure. This video was originally created for Great Britain’s Fieldsports TV Channel.

This is an outstanding video, recommended for anyone interested in long-range hunting.

Long range shooters Lindroth and Haugland traveled to the Arctic Circle to field test a new .338 LM Blaser R8 (in GRS stock) fitted with a Zeiss Victory V8 4.8-35x60mm scope. (Ammo is Norma-brand .338 Lapua Magnum). The video shows how they confirm the ballistics of the Norma factory ammo in the Blaser R8 rifle system.

Norway Fjord .338 Lapua Magnum Norma Blaser R8 Zeiss

Ulf and Thomas initially test out the system confirming drop at multiple yardages, and then use the rifle for practical accuracy. Ulf says: “If you know your hunting will demand a long shot, and you want to push the limit but still be sure to make the first-shot kill… If you want to do an ethical hunt, if you want to push that limit, you have to do [this kind of testing].”

Norway Fjord .338 Lapua Magnum Norma Blaser R8 Zeiss

Ulf Lindroth (above) observed: “We shot [at 808 meters] observed the misses, clicked our way into the target, and now we have the true drop at that distance… in this air pressure, in this temperature. From there we can start working to find our TRUE trajectory. And when we have THAT… we can get serious about some target shooting.”

New 33 Nosler Rivals .338 Lapua Magnum in Smaller Package

nosler 33 .338 404 Jeffrey Magnum cartridge

Nosler has just introduced a new SAAMI-spec .338-caliber cartridge, the 33 Nosler, which is based on the 404 Jeffrey parent case. This efficient new cartridge rivals the velocity and energy of the proven .338 Lapua Magnum while using significantly less powder. AND, the Nosler 33 fits in a standard, long action receiver. Accordingly the 33 Nosler should be popular with extreme long range (ELR) shooters and big game hunters. The 33 Nosler fires .338-caliber bullets which are tough on big game and typically boast high Ballistic Coefficients and sectional densities. For long-range target work, Nosler will offer 33 Nosler match ammo with a high-BC 300gr bullet.

nosler 33 .338 404 Jeffrey Magnum cartridge

Notably, the 33 Nosler will fit in a standard-length Long Action. That’s a big deal because it means you can now achieve .338 LM performance in a rifle that is lighter and less costly to build. Nosler lists a 3.340″ COAL for the 33 Nosler. Compare that to 3.681″ for the .338 LM. Nosler will offer loaded ammunition as well as 33 Nosler brass.

nosler 33 .338 404 Jeffrey Magnum cartridge

The above chart was created by Nosler. It shows the 33 Nosler can push a 225gr AccuBond at 3025 fps and the 265gr AccuBond at 2775 fps. That’s 275 fps faster (with 20% more energy) than the .338 Winchester Magnum using the same length action. According to the chart, the 33 Nosler is also 25 fps faster than the .338 Lapua Magnum at the muzzle while burning 18% less powder. However, the numbers quoted by Nosler for the .338 LM are conservative.

nosler 33 .338 404 Jeffrey Magnum cartridge

The 33 Nosler® is SAAMI-standardized for consistent industry-wide brass and chamber dimensions. Nosler will be supporting this new cartridge with Nosler Brass, factory ammunition, and Nosler factory rifles. Expect 33 Nosler products to be available in early 2017.

Mark’s Milestone — Shooting a Savage at 1760 Yards

Savage BA110 .338 Lapua magnum 1 mile

When we first ran this story a couple years ago, it proved immensely popular with our readers. In case you missed it the first time around, check out what can be done with a factory Savage 110 BA at extreme long range — 1760 yards (one mile). Shooter Mark Dalzell did a great job with the video, which features multiple camera views so you can see the shooter and the target at the same time. Enjoy!

This video by Mark Dalzell demonstrates the long-range capabilities of the Savage 110 BA chambered in .338 Lapua Magnum. Mark took his “BadAss” rig out to the southwest Nevada desert just north of Jean Dry Lakes. He placed a 2’x3′ target way, way out there — a full mile (1760 yards) away. At that range, flight time to target was 3.75 seconds! Sighting with a Nightforce 5-22x50mm NXS scope, Mark needed a few shots to get on target, but eventually made multiple hits, using 67 MOA of elevation and 2.25 MOA left windage. You can view the hits starting at 1:56 time-mark on the video. (Mark had a second camera set up closer to the target — this displays frame in frame in the video, and if you watch carefully you can see the strikes.) The ammo was HSM 250gr HPBT match with a 3.600″ COAL. The shooting was done at 8:13 in the morning, with clear conditions, very light winds. Temp was 57°, humidity 24.5, Density Altitude 3666. Video soundtrack is La Grange by ZZ Top.

Good Shooting Mark. That’s darn good for a factory rifle. You also had the elevation dialed in real close before the firing started! That shows a good knowledge of your ammo’s long-range ballistics. We also noticed how effective that muzzle brake was. Recoil looked about the same as an un-braked .308 Win.

If you thought Mark’s 1760-yard shooting was impressive, Mark has produced another video that shows a session at even greater distances — out to 2300 yards. Watch Mark Dalzell Shoot at 2300 Yards.

High-Tech Tactical Rifle from Austria’s Ritter & Stark

Ritter & Stark Austria tactical modular SX-1 rifle .300 Win Mag .338 LM Lapua Magnum

Ritter & Stark Austria tactical modular SX-1 rifle .300 Win Mag .338 LM Lapua Magnum

There’s a new long-range precision tactical rifle from Ritter & Stark (R&S) of Austria. The new SX-1 Modular Tactical Rifle (MTR) is designed to allow rapid barrel changes for three chamberings: .308 Winchester, .300 Winchester Magnum, and .338 Lapua Magnum.

Notably, the scope rail is mounted on the barrel itself, and the bolt locks directly into the barrel. This patented system allows scope, rail, and barrel to be swapped out as one integrated assembly, which should definitely help maintain zero when barrels are exchanged.

Ritter & Stark Austria tactical modular SX-1 rifle .300 Win Mag .338 LM Lapua Magnum

Ritter & Stark Austria tactical modular SX-1 rifle .300 Win Mag .338 LM Lapua Magnum

Ritter & Stark explains: “The MIL-STD 1913 Picatinny rail is installed directly on the barrel, allowing barrel interchangeability with pre-set scopes for no shift of impact when changing calibers. Easily and quickly done in the field, the patented caliber conversion system allows the barrel to be precisely positioned in the machined aluminum receiver with a greater area of contact allowing for more stability. The bolt is locked directly into the barrel breech[.]”

Video Shows Barrel Swap System, and Bolt Locking in Barrel Breech:

Ritter & Stark Austria tactical modular SX-1 rifle .300 Win Mag .338 LM Lapua Magnum

CNC-Controlled Rifling Process
Ritter & Stark states: “The rifling is processed in a CNC-controlled electrochemical machine. This avoids the transmission of thermal effects and mechanical stress to the material. Furthermore, this process allows us to produce barrels with unique uniformity and within tolerance zones that were not possible in a serial production before.” This is very interesting technology, and we’d like to learn more about it.

Accuracy Guarantee and Barrel Life Guarantee
Apparently the CNC-controlled rifling process works well as Ritter & Stark guarantees that its barrels maintain accuracy for a long time. The Austrian company states: “Our barrels are guaranteed to at least 5,000 rounds for .308 Win and .338 LM, and 2,000 rounds for .300 WM before noticing any degradation in accuracy.” That kind of claim certainly invites a long-term test. Who’s got enough ammo? Ritter & Stark also claims that “every rifle we manufacture can achieve 0.5 MOA 3-­round groups or better with factory match-grade ammunition.”

The Ritter & Stark SX-1 MTR is designed for adaptability. It will accept third-party Rem 700-compatible triggers as well as a variety of AR-type grips. In addition, the SX-1, in standard configuration, will accept other manufacturers’ AI, SR25, or AR10 magazines. The rifle can also accept other buttstock assemblies compatible with Ritter & Stark’s folding mechanism which, interestingly, can be set to fold to either side.

A Look Inside Sierra’s 300m Underground Test Tunnel

Sierra Bullets Test Tunnel Barrels

Ever wonder how (and where) Sierra tests its bullets? The answer is underground, in a 300-meter test tunnel located under Sierra’s factory in Sedalia, Missouri. The photo above shows the construction of the tunnel back in May, 1990. Like most bullet manufacturers, Sierra does live-fire bullet testing to ensure that Sierra projectiles perform as promised, with repeatable accuracy. Sierra’s 300-meter test range is the longest, privately-owned underground bullet test facility in the world. Sierra offers free tours of the test tunnel as part of Sierra’s Factory Tour Program.

Sierra Bullets indoors testing barrels

Sierra Bullets tests every new bullet design and each lot of bullets. Sierra tells us: “When [we] change to a new bullet they are continually shooting them until they get the bullet properly set up and running and the range releases them to run (meaning the bullets shoot to spec). [Testers] are required to shoot at any lot change and periodically throughout the lot … even if it is just a press operator change. Lot sizes can vary from 5,000 to over 100,000 thousand. If anything changes — it is a new lot. When a new operator comes on — it is a new lot.”

Bevy of Barreled Actions for Bullet Testing
Sierra Bullets uses dozens of barreled actions for testing bullets. These barreled actions are clamped in stout, return-to-battery test fixtures. These heavy test fixtures provide near-perfect repeatability (with no human-induced holding or aiming errors). Each barrel has its own logbook to track the barrel’s usage. Interestingly, Sierra does not have a specific round count for barrel life. When a barrel starts “opening up”, i.e. showing a decline in accuracy, then the barrel is replaced, whether it has 800 rounds through it or 5,000.

Sierra Bullets 10-Shot Groups at 200 yards
What kind of 200-yard accuracy can you get in an enclosed, underground test range? Would you believe 0.162 MOA at 200 yards with a .338? Check out these 10-shot test groups shot at the Sierra Test Range at 200 yards. Note that the numbers listed on each sample are actual measurements in inches. To convert to MOA, cut those numbers in half (to be more precise, divide by 2.094, which is 1 MOA at 200 yards). For example, the 0.340″ middle group works out to 0.162 MOA at 200 yards.

.338 Lapua Magnum + Cleaning Rod + Inattention = Kaboom!

Kaboom at Manatee!
A while back, Sniper’s Hide member Queequeg published shocking photos of a catastrophic kaboom involving a .338 Lapua Magnum (Savage action). The action was blown off the rifle, shrapnel went through the roof, and the barrel split at the tenon before taking an excursion downrange. The action did crack in the front but the lugs remained engaged so the bolt did not slam to the rear (luckily for the shooter).

Here’s the report: “This happened [January 20, 2014] at the Manatee Gun and Archery Club. Al, Ren and myself were there with a couple other folks. Ren was at bench 12, I was at 13. The fellow at 11 was running a Savage .338 Lapua. He had a very bad day! He damn sure could have killed himself and quite likely Ren as well.”

Queeqeg added: “After the boom, I heard Ren ask ‘Are you alright’ and then turned to look in time to see the fellow reacting in total shock — literally stunned. Ren and I went over to him and could not see any major injuries. Ren was uninjured as well but had a lot of fiberglass splinters on him. The barrel nut is what I presume punched the two holes in the roof. The shooter is a regular there[.] He had been having a problem with sticky cases though he said he was certain the loads were mild. That’s why he was content to knock the sticky ones out with the rod. He simply forgot to remove the rod after knocking out the last stuck case. You can see what happened next.”

The Important Lesson Here
What did the .338 LM shooter do wrong here? You will say — “Well that’s obvious, he left a cleaning rod in the barrel and then shot a round.” Yes, that was a potentially fatal error. But that was his second mistake — one that occurred only because he made a more fundamental judgment error first.

The FIRST mistake was not acknowledging the problem with his ammo. Had he heeded the warning signs, he would still have a rifle (and an unsoiled pair of trousers). When he first observed that he was having problems with extracting cases, a warning light should have gone off in his head. Presuming his extractor was not broken (and that the chamber was cut properly) he should have been able to extract his brass if he was running safe loads. The lesson here we all need to learn is that if you observe a serious ammo-related issue, it is time to stop shooting. Don’t try to invent work-arounds just to extend your range session, when there are clear signs that something is wrong, very wrong.

.338 Lapua Magnum at 1.43 Miles — Video Shows Hits on Steel

Savage 110 BA .338 Lapua Magnum Berger Hybrid Bullets

Here’s a report posted by long-range shooter Grizzman on the LiveLeak video hosting site. Grizzman engaged an 18″x24″ steel target at the distance of 2530 yards — 1.43 miles. Grizzman produced a great video that really gives you a sense of the distance (see the zoom footage at the 0:30 time mark). At this distance, the ballistics are remarkable. Grizzman’s .338-cal, 300gr Berger Hybrid bullets went transonic at 2400 yards and dropped 228 feet (69.5 meters) over their 2530-yard trajectory.

WATCH Video — Second camera at target records bullet impacts (see and hear the hits):

You can see more Long-Range Shooting Videos on Grizzman’s Live Leak Channel. Among the interesting videos is a 1K Cinder Block Shoot: .338 LM Shoot Cinder Blocks at 1000 Yards.
