ELR – Go Big or Go Home?

By Mark V. Lonsdale, STTU

When a shooter steps up from long range shooting (1,000 yards) to extreme long range (1,500+ yards) he or she is also stepping up to some heavy fire power – with the emphasis on HEAVY.

The rifles that have been winning at the King of 2 Miles (Ko2M) are in the 40-pound category with .416 Barrett being the ruler of the roost.

But when you get serious about ELR shooting, you are also investing in a purpose built rifle. In the early days of ELR shooters were running their .338 Lapua Magnums, but then stepped up to .375 Chey Tac. Both are excellent ELR calibers, but they have their limitations; so much so that the minimum caliber for consideration for the Ko2M is now .375 CT.

While bullet weight and BC are considerations, one of the biggest advantages of the bigger calibers is being able to see the splash at extreme ranges. This is important since it is all but impossible to read wind accurately at 2,000 to 3,000 yards, so the best wind indicator is the dust kicked up by an impact in the dirt or on the rocks – the splash.

While the .338 Lapua Magnum, in the 14-16 pound range, is a practical sniper rifle for military operations, the 40+ pound .416 Barrett is not practical for field operations. It could, however, be used in fixed position defense. 

The effective range for a .338 LM is in the 1,500 to 2,000 yard range. The .375 Chey Tac has proven effective out passed 2,500 yards. But the Ko2M goes to 2 miles / 3,520 yards.

Now it is possible to score hits at longer ranges with the .338 and . 375 under ideal conditions, but when we talk about “effective” it should be defined as the range at which a rifle and competent shooter can score 80% hits. In other words, it may take one or two shots to get on target and read the wind, but then the next series should be solid hits on a 36″x36″ ELR target.

So before you invest several thousand dollars in an ELR rifle, it is important to understand the limited use you may get out of a purpose built rifle. Not too many shooters have access to shooting ranges out passed 1,000 yards, and even fewer to 3,000 yards.

But if you have the time, inclination, and disposable income, ELR is a real challenge and a lot of fun.

Range Tools – Don’t Get Caught without Them

By Mark V. Lonsdale, STTU

As with many of you, I’ve been on public rifle ranges where some new shooter turns up with a new rifle and scope but has no tools to mount it. Or the scope is mounted incorrectly and they don’t have the tools to correct it. Or someone has a squib load but has no cleaning rod to knock the bullet back out of the bore.

M6 2018

Various Allen and Torx screws and bolts requiring the correct tools. Rifle is a 300 WinMag in a McMillan A6 stock

In the same vain, any time I run a precision rifle class participants are instructed, well ahead of time, to turn up with their rifles and scopes zeroed at 100 yards. Unfortunately many are not.

Reasons participants have given for not having a zeroed rifle:

  • I signed up at the last minute and no one told me
  • I just bought a new rifle this week
  • I changed ammunition and haven’t re-zeroed
  • The gun shop just installed a new scope for me
  • My friend gave me some reloaded ammo for the class
  • I think it’s zeroed but not sure

So needless to say, the precision rifle class turns into Rifle 101 and the first morning on the range is dedicated to zeroing rifles. But when it comes time to zero out the scope dials, invariably, all but one or two will not have the correct Allen wrenches to zero their dials. Even a gunsmith in one class had no tools.

On left, small tool with all the necessary Allen and Torx wrenches in a small Pelican case. Right is a Leupold 65 in-lb T wrench and a conventional variable torque wrench (top)

Scopes come with the Allen wrench sized for that scope dial, but most scopes use one of three basic Allens so I carry all three. So shooters should have a small pouch that carries all the tools needed to tighten any bolt or screw on their rifles. This is primarily the action bolts, the scope ring screws and nuts, and Allens for the scope dials and trigger adjustment (if running an adjustable trigger such as Timney or Jewel).

Back to the participants in precision rifle classes, often times they not only do not have the right tools, they don’t know the required torque values for their actions and scopes. An experienced shooter or gunsmith can often button up the bolts by “feel” but rookie shooters can only learn the correct feel by using torque wrenches set to the correct values. This also prevents stripping out small screws such as the scope ring-halves screws that only require 15-18 in-lbs (depending on manufacturer recommendations).

Basic tools include:

  • Allen for action/stock bolts (or screwdriver for slot screws)
  • Allen for scope base
  • Allen for scope ring-half screws
  • 1/2” socket for the ring side nuts
  • Allen for trigger adjustments
  • Torque wrench
  • Allen for stock butt plate adjustments
  • Lens cleaning brush and soft cloth
  • Tools for additional accessories such as light mounts, lasers, or bipods

To conclude, save the instructions that come with your rifle, scopes, scope rings, mounts, and triggers. Most of these of these have specific torque values. Next, save any tools that come with these as well. Put them in a small pouch or Pelican box, or add them to your Fix it Sticks, and keep them with the rifle or in your range bag. Lastly, since we all have several rifles, maintain a small notebook or log book for each rifle so that you have a notation of required torque values and the ammunition you used when you last zeroed the rifle.

By Mark V. Lonsdale

ELR shooting can be both addictive and expensive, even though hit probabilities are often low. With a match like Ko2M in Raton, New Mexico, a competitor could drive a thousand miles to shoot just six shots and be eliminated. If a shooter does not hit the first target, he or she does not advance. In other forms of competition a competitor gets to shoot 80 to 250 rounds before the day is done.

So what’s the attraction when the rifles and ammo are so expensive? ELR is like hitting that one golf ball 300 yards on a driving range, shooters choose to remember that one impact on steel at a mile (1,760 yards), while failing to attach a percentage or hit probability factor. In ELR competitions, it is not unusual to see the hit count drop to below 10% at longer distances.

One of the reasons rookie shooters enjoy ELR shooting is that, unlike other shooting disciplines, everyone misses long range targets – even national and international champions. So when the rookie goes zero for five shots at 2,500 yards, he or she does not feel so bad, because a former champion probably also went zero for five.

If that same rookie shooter was to enter an F Class F-TR competition, where all the top shooters are shooting near perfect scores (200 out of 200 at 1,000 yards), his or her lowly score would be a little disheartening. However, the serious rookie shooter will take a low score as motivation to improve next time, and by having a quantifiable score to aim for, it is easier to track progress.

Targets f-class

But with ELR shooting, it is almost impossible to have a quantifiable score to build on since  chance plays such a big part of ELR shooting. Why is this? Simple answer – Wind.  On a calm day, most top ELR shooters can go 5 for 5 at 2,500 yards, but on a windy day the scores drop dramatically. Unlike formal long range shooting disciplines, that are shot on a flat range with range flags to assist in reading wind, ELR matches have no down-range wind flags. ELR matches are also shot over irregular terrain replete with canyons, valleys, ridge-lines, draws and spurs. All of which contribute to unpredictable and often unseen wind changes in both velocity and direction.

As an example, at the 2019 FCSA ELR Record Challenge at the NRA Whittington Center in Raton, not one shooter was able to hit the 2,300 yard target because of tough weather and wind conditions, and an inability to spot misses. This harkened back to the first Applied Ballistics ELR Central World Record attempt in Pahrump, NV, January 2018. Only one shooter, Nate Stallter with Team Tubb, was able to go 3 for 3 at 2,011 yards on a 36”x36” target, and no one hit 2,500 yards. Again, why? The single biggest reason was a strong, variable cross-wind and no wind indicators down-range.

This is what makes ELR shooting both exciting and frustrating. Just like watching a high-roller gambling on the roulette wheel, spectators all want to see him or her win, but the gambler has no control on where the wheel will stop. It is nerve racking, but it is still all chance. With ELR shooting, everyone wants to hit the extreme long range targets, but the wind becomes the element of chance. Thanks to Applied Ballistics and Kestrel Ballistics, many of the variables such as bullet drop, spin drift, and Coriolis have become predictable, but down-range wind is still an art, not a science.

While serious ELR competitors invest heavily in rifles, optics, ammunition, and accessories, they are still at the mercy of the elements. Even the best shooters in the world cannot guarantee hits at 2,500+ yards when the winds are strong and changeable.

At best, if the shooter or spotter can spot a miss impact in the dirt or on a rock face, he or she can adjust aim and shoot quickly before the wind changes. But when the bullet’s flight time is several seconds, there is a high probability that the wind will have changed again, leaving the shooter chasing the wind for an elusive impact on steel. As little as a 1 mile per hour wind change can put the bullet off the target, but reading the difference between an 8 mph wind and a 10 mph wind at 1.5 miles (2,640 yards) is all but impossible. As an example, a 1 mph 3 or 9 o’clock wind moves my .375 CheyTac 0.55 MOA laterally at 1,000 yards, but 2 MOA at 2,500 yards. That’s 53 inches and a complete miss with a flight time of 4.6 seconds.

As an example of just how changeable winds can be in a mountain environment, at the 2019 FCSA 1.5 Mile Challenge, the 2,268-yard target was on a rock face up on the side of a ridgeline. My first shot was a hit so I reloaded and fired a second shot as quickly as possible. The second shot impacted about 20 feet to the right of the target, so obviously a strong left to right wind, from 9 o’clock, had picked up, even though wind at the shooting position was right to left (from 3 o’clock). My spotter called the miss, I made sight adjustments and fired again. The third shot was an impact, so again, I fired again quickly. The forth shot impacted the rock about 8-10 feet above the target, indicating a tail wind coming straight up the valley and then up the rock face.

The lesson here is that none of these wind changes were visible or predictable because of the uneven mountainous terrain. I was just fortunate to get some hits. Another shooter could shoot ten minutes later and have no wind at all. This is the nature of long range shooting and the fact that some shooters may have little to no wind early in the morning, but those slotted to shoot later in the day may have hellacious winds. The only thing predictable about Raton is that the wind picks up later in the morning so everyone hopes for an early morning luck of the draw.

Now don’t get me wrong – there is still a lot of skill required to be a successful ELR shooter, but even world-class wind coaches, who have proven themselves in 1,000-yard F-TR competition, nationally and internationally, struggle with the fickle winds of ELR mountain shooting. But the stats show that we are getting better. In earlier Ko2M competitions, 50% of the shooters were eliminated after the second target at only 1,556 yards. In 2018, only 21% of shooters hit Target #3 in the qualifying rounds, and only 9.7% hit Target #1 in the Finals. But this year, 2019, 82% of the shooters hit Target #1 at 1,692 yards, and 50% hit Target #2 at 1,891 yards. But in the finals, no one managed to hit the 2-mile target (3,525 yards).

Team McMillan

As for fundamental marksmanship, one still needs to be a highly competent competitive shooter to be successful in ELR. The rookie shooter should keep in mind that the ELR Central targets are 36”x36” which is only 1 MOA at 3,500 yards. So if you can’t hold 1 MOA at 300, 400, and 500 yards, you will definitely not be doing it at 2,200, 3,200, or 3,500 yards. The Ko2M 2-mile target is 48”x60” which is still only 1.3×1.63 MOA. So even with no wind, a competitor needs to have good combination of rifle, optics, ammo, shooter, and spotter – with bullet BC, stability, and wind-bucking characteristics being extremely important.

To wrap this up, just like on the driving range in golf, everyone remembers that perfect 300 yard drive straight down the fairway, but chooses not to remember all the slices and hacks that went out-of-bounds. It is the same in ELR shooting. Everyone remembers the one hit they got at 2,000 yards, but don’t mention the ten or twelve shots it took to walk the bullets in. Similarly, hitting a 3,500 yard plate once, under ideal conditions, does not necessarily make one a Ko2M contender. It may fire up his or her enthusiasm for ELR shooting, but on match day, under less than ideal terrain and wind conditions, only a small percentage of shooters make it to the finals.

.416 Barrett ELR rifle

Final recommendation – take every opportunity to shoot in variable windy conditions over uneven terrain. And you don’t have to burn out the barrels on your ELR rifles. 1,000-yard shooting with a .308 Win or 6.5 Creedmoor is more economical and still excellent practice and experience.

Parting shot – ELR shooting is a low probability game requiring a lot of skill and more than a little luck.

Bullets & Barrels – Making the Right Choice

By Mark V. Lonsdale

Premise: What’s more important – the bullet or the barrel twist?

I see more than a few rookie shooters on Facebook asking about the best load for a specific bullet but without knowing their barrel twist. Conversely, several asked about running a particular bullet in a barrel twist that is completely unsuited to that bullet weight.

To simplify this dilemma when getting into precision long range shooting, if you already own the rifle and know the barrel twist, then select a bullet that is best matched to that twist rate, either target or hunting bullet. And if you don’t know the twist, then mark a cleaning rod and measure how many inches it takes to make one full rotation as it is pushed into the bore.

As a practical example, in .308 Winchester most factory rifles are manufactured in 1:12” twist or 1:10” twist. The 1:12” barrels were intended for the 150, 165, and 168 grain bullets, target or hunting. The 1:10” were more suited to the heavier 180, 185, and 190 grain bullets. When the Marines requested a 175 grain SMK, it was thought that a better barrel twist would be 1:11.5” Since I own several rifles in all three barrel twists, and shoot them more than any other caliber, it is safe to state that the 168 SMKs shoot great in all three twist rates, but I have opted to running Bartlein 1:11.5” barrels in my newer .308s. This works great with both 168 and 175 SMKs. The 185 Juggernauts, 190 SMKs, 200 Hybrids, and 215 Berger Hybrids, definitely shoot better in the 1:10” twist that I have in my F-TR rifles and 300 WinMags. As with many long range shooters, I prefer 200 grain Hybrid bullets for 1,000 yard shooting, and 215 Hybrid or 210-220 SMKs out to 1,500 yards, in .30 caliber.  After that we are into .338 or .375 country.

In the lighter calibers such as 6.5 Creedmoor, I’m running medium and heavy Palma 1:8” twist barrels but have found a significant difference in precision accuracy with various bullet weights. After considerable testing with 130, 140, 142, and 147 grain bullets, hands down my rifles prefer the 140 grain bullets. Consistent 0.5” groups don’t lie. So this was a case of barrel first and then find the right bullet.

Hornady 140 ELD-M (left) 142 SMK (right)

If you are planning on buying or building a custom rifle, you first select the bullet you wish to shoot and then match the barrel twist to that bullet. For example, for ELR shooting, the 400 grain Lazer Cutting Edge bullets in .357 CheyTac and the 550 grain Lazers in .416 Barrett have proven to be winners. For .338 Lapua Magnum, the choice may be the 300 Sierra Matchking or the Cutting Edge 275 Lazer – one jacked and one solid.


Running Cutting Edge 550 Lazers at the 2019 Ko2M

The general rule is that heavier bullets prefer faster twist barrels; and you can run even faster twist barrels with solid bullets as opposed to jacketed bullets. For example, in .338 Lapua, you can run a 1:9” or 1:10” with 300 grain SMKs, but a faster 1:8” with the solid 275 Lazer. The danger of pushing a jacked bullet too fast through a super-fast twist barrel is it may strip the jacket and the bullet may come apart.

This project .338 Lapua Magnum, built on a Stiller’s TAC338 action, will have a Bartlein 1:9″ twist barrel to optimize the Sierra 300 SMKs. But will also run tests with Cutting Edge .275 Lazers for comparison and ELR shooting. 

Another reason for fast twist barrels and bullets in ELR shooting is retained RPM at extended ranges. RPM is one of the components of bullet stability so it makes sense that if the bullet starts out at a higher spin rate, it will retain more RPM as it passes from super-sonic into trans-sonic and subsonic.  Thus the reason that solid bullets such as Cutting Edge dominate in ELR matches.

The final option, whatever barrel twist you may have on your factory or custom rifle, you can always re-barrel the rifle to the optimum twist for your chosen bullet and application. Serious competitive shooters consider match barrels as consumable, just like tires on your car. Just as you can change tires to best suit the conditions, you can change barrels to best suit your shooting needs. Similarly, when the barrel becomes worn and loses accuracy, just spend the $350 and get a new one. I have blue-printed actions and McMillan stocks that are 30 years old, but all it takes is a new match-grade barrel to have a new match-grade rifle.
