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.

416-338

416-338LM

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.

375CT-338LM

.375 Chey-Tac, in the back, built by Hill Country Rifles on a Stiller’s Action and McMillan A5 Super Magnum stock, weighing in just under 25 pounds. Three inches shorter, the .338 LM in the foreground weighed in at 16 pounds, both with Accu-Tac bipods  

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.

Berger Wins Sub-Contract For Advanced Sniper Rifle Program Ammunition

Berger Wins Sub-Contract For Advanced Sniper Rifle Program Ammunition

The single-year contract specifies 800,000 rounds of .300 Norma Mag. that will be loaded with Berger’s .30-cal., 215-grain hybrid bullets along with Lapua brass. The contract also includes 200,000 rounds of .338 Norma Mag. loaded with Lapua’s .338-caliber, 300-grain armor-piercing AP529 projectiles and Lapua brass. This .338 Norma Mag. load extends the range for snipers over the .300 Norma Mag. load. Berger and Lapua products had already been chosen for the Advanced Sniper Rifle program ammunition—now the loads themselves will be produced by Capstone. Ammunition for the contract will be loaded and tested at the aforementioned facility in Arizona.

With both brands well known by competitive shooters for high quality and match-grade precision, the combination of Berger bullets and Lapua cartridge cases for the Advanced Sniper Rifle program’s .300 and .338 Norma Mag. ammunition should prove potent for the U.S. military.

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).

Compact set of Deluxe Fix it Sticks complete with pre-set torque wrench heads and T handle

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

Tool kit sniper

Sniper tool kit complete with notebook and Kestrel wind/weather meter and spare batteries 

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.
