Tech Insight — Acrylic Machining Process
The folks at Bullets.com tell us that machining acrylic is not as easy as it seems. Making precision blocks is a multi-stage process involving special equipment. Solid slabs are first machined flat so they are parallel. Then several custom cutters are employed to craft precisely-arranged holes with nice chamfers on each hole as well as the outside edge. Every hole bottom has a secondary primer pocket milled in so the primers do not contact the bottoms. The see-through blocks are finished to a nice sheen.

A Kestrel Wind Meter will record wind speed with its impeller wheel. However, to get the most accurate wind velocity reading, you need to have your Kestrel properly aligned with the wind direction. To find wind direction, first orient the Kestrel so that the impeller runs at minimal speed (or stops), and only then turn the BACK of the Kestrel into the wind direction. Do NOT simply rotate the Kestrel’s back panel looking for the highest wind speed reading — that’s not the correct method for finding wind direction. Rotate the side of the Kestrel into the wind first, aiming for minimal impeller movement. The correct procedure is explained below by the experts at Applied Ballistics.
How to Find the Wind Direction with a Kestrel Wind Meter
Here is the correct way to determine wind direction with a Kestrel wind meter when you have no environmental aids — no other tools than a Kestrel. (NOTE: To determine wind direction, a mounted Wind Vane is the most effective tool, but you can also look at flags, blowing grass, or even the lanyard on your Kestrel).
Step 1: Find the wind’s general direction.
Step 2: Rotate the Wind Meter 90 degrees, so that the wind is impacting the side (and not the back) of the wind meter, while still being able to see the impeller.
Step 3: Fine-tune the direction until the impeller drastically slows, or comes to a complete stop (a complete stop is preferred). If the impeller won’t come to a complete stop, find the direction which has the lowest impact on the impeller.
Step 4: Turn the BACK of the Kestrel towards the direction from which the wind is blowing. Then press the capture button, and record your wind speed.
Do NOT simply point the Kestrel’s back into the wind until you get the highest wind speed — that’s not the correct method.

Ruger has introduced one of the most important factory rifles in years — the new Ruger Precision Rifle (RPR). The new RPR features the three-lug (70° bolt throw) action from the Ruger American Rifle mounted in a modular chassis system with many innovative features, such as cam-lock buttstock adjustments, and a “universal” mag well. Even with a hammer-forged barrel, the gun is very accurate. Everybody who has shot this gun so far has been impressed. This is a smart design, well executed. We predict Ruger will sell a ton of these guns. The new RPR is logical step up for AR owners seeking better long-range accuracy (and easier maintenance).
The RPR is currently offered in three chamberings with three different barrel lengths: .308 Win (20″ bbl, 1:10″-twist, 9.7 lbs); 6.5 Creedmoor (24″ bbl, 1:8″ twist, 10.6 lbs); and .243 Win (26″ bbl, 1:7.7″-twist, 11.0 lbs). All barrels are hammer-forged with 5R rifling, and are threaded 5/8″-24 at muzzle for brakes and suppressors. MSRP for all three models is $1399, so expect street price to be under $1200. You could pay that much for some tactical chassis systems by themselves, and then you’d still have to purchase action, barrel, and trigger!
So how does it shoot? Ruger designed the RPR to deliver sub-MOA 5-shot groups. At the media preview, using Hornady 6.5 Creedmoor factory ammo, test rifles shot well under 1 MOA, and in many cases closer to half-MOA. Frank Galli of Snipers’ Hide had a few three-shot groups in the twos. We would like to test this rifle with .308 Win hand-loads and a custom barrel — now THAT would be interesting…
Video Shows Features of Ruger Precision Rifle Receiver:
The lower receiver is CNC-machined from a 7075-T6 aluminum forging, Type III hard-anodized. The mag well front is contoured for bracing against shooting supports. The rifle even comes with a built-in +20 MOA tapered Picatinny scope rail. The trigger, unique to this gun, adjusts from 2.25 to 5 lbs. using a special tool that stows in the bolt shroud. The trigger has a Savage-type safety insert.
The buttstock is fully adjustable with quick-adjust cams. But if you prefer a different style of buttstock, that’s do-able — the left-folding stock hinge is attached to an AR-style buffer tube, so the MPR will accept any AR-style stock. Likewise, you can attach any AR-compatible forearm to the RPR.
Seven Patents Pending for RPR
Notably, Ruger has seven patents pending for this new rifle — that shows the design innovation packed into the RPR. Ruger is pursuing patents on the universal magazine latch system, dual barrel nut system, trigger system, dual-action stock cam levers, bolt body design and other features.
The RPR boasts a Universal Mag Well that works with front-latch AND side-latch mags.
Forum member Steven Blair notes the barrel attachment system is different than an AR: “It doesn’t incorporate a barrel extension, the bolt locks in the receiver. It does have a shoulder larger than the main barrel diameter that would require turning the full barrel length.”
Sniper’s Hide Boss Tests Ruger Precision Rifle
Frank Galli, head honcho of Snipers’ Hide, recently tested the 6.5 Creedmoor version of the RPR. Galli says the rifle offers excellent accuracy and an impressive feature set. Galli believes the RPR offers great value compared to a custom-built tactical rifle that could cost $3500 or more. Read Galli’s detailed review on the Sniper’s Hide website.

Sniper’s Hide Boss Frank Galli reports:
This is a full-featured, precision rifle with an entry-level price tag. The feature list of this rifle is huge. I could probably write 1800 words and still not explain everything packed into this rifle. But suffice to say, it’s customizable. If you wanted to change the stock, use any AR15-capable stock, Magpul PRS, no problem. Want to change the fore-end, same thing, you can add any AR15 fore-end…. The only feature you cannot change is the trigger.
At distance, it’s easy to say, this rifle performs, in the video we [show] a 1/2 MOA Group at 850 yards on steel. The muzzle velocity with factory 140gr AMAX is 2810 fps out of this rifle.
This is the entry-level precision rifle that can put you in the mix of any precision rifle competition held anywhere in the US for under $2500 with scope. What is your excuse now?

We recently published our comprehensive 6.5×47 Lapua Cartridge Guide, researched by the 6.5 Guys. In case you’ve been wondering what kind of accuracy is possible for a tactical-type rifle chambered for this mid-sized cartridge, check out this tack-driver built by gunsmith Ryan Pierce. That’s a mighty impressive 0.206″ five-shot group fired with Berger 140gr Hybrids using a Brux cut-rifled barrel. The powder was Hodgdon H4350, a very good choice for this cartridge.
Ryan reports: “Here is a 6.5×47 I built for a customer. It features a trued Rem 700 action, Brux 1:8″ Rem varmint-contour barrel, Mcmillan thumbhole stock, Surgeon bottom metal, and 3-port muzzle brake. The customer’s preferred load is the same that has worked in the last couple dozen 6.5x47s I’ve built: 41.1-41.3 grains of H4350 with 140 hybrids .050″ off the lands. This should run about 2810-2815 fps from a 26″ barrel. The 3.128″ refers to length of a loaded round from the base to ogive including the Hornady ogive comparator tool.”

The CMP’s National Trophy Infantry Team Match (NTIT) has been a staple at the National Matches since 1922. Also known as the “Rattle Battle,” the event is one of the most unique in the competitive rifling world — scoring is based on how many hits six-person teams can score on a bank of targets during a series of 50-second firing periods at four yardages. Teams begin the NTIT match with 384 rounds of ammunition, which they fire upon eight silhouette targets from 600, 500, 300 and 200 yards during successive 50-second periods. After each rapid-fire string, team members move forward (to the next-closest distance) carrying all equipment from firing line to firing line. The match emphasizes extremely fast, accurate fire and good communication among teammates. The Rattle Battle is always an exciting competition for spectators to watch. View NTIT match results on the CMP website.

Reactive targets — whether balloons, steel gongs, or clay birds — always add fun to a range session. But precision shooters may want something more challenging (i.e. smaller) than a clay bird when shooting inside 300 yards. For a change of pace, try shooting at inexpensive pool cue chalks. Less than 1″ square, these will test your marksmanship skills.
Pool Cue Chalks — Cheap, Fun, Dramatic
If you’re looking for a small target that makes a nice big cloud of color when hit, try pool cue chalks — those little blue cubes you use to dust the end of billiard cues. Measuring about 7/8″ per side, billiard chalks make very challenging targets at 100 and 200 yards. When you hit them, if you nail the circular “dimple” in the middle, they disintegrate impressively, tossing blue “smoke” in all directions. Billiard chalks are inexpensive. You can buy a dozen chalks online for about $3.00 — just 25 cents each. And the prices drop with more quantity. One gross of chalks (that’s 144 pieces) costs just $19.95 at ozonebilliards.com.
To see actual hits on chalk at 100 and 200 yards, watch the video above. (WARNING: Soundtrack is loud and advertisement may play before movie.) The movie-maker, Phil of the Random Nuclear Strikes Blog, cautions that: “You’ll notice (in the video) that some of the hits are ‘wiffs’ instead of ‘poofs’. If you look at the picture above, you’ll see the 1/2 inch dimple in the cube face. If you don’t put the bullet in that dimple, it’ll ‘wiff’ on you.”

Garand matches are among the most popular and well-attended of the CMP competition disciplines. When obtained directly from the CMP, Garands are fun to shoot and affordable. However, with these classic battle rifles, you need to ensure that the headspace is set properly to ensure safe function and good brass life.
In the archives of The FIRST SHOT, the CMP’s online magazine, CMP Armorer John McLean has written an excellent article entitled: “Everything You Ever Wanted to Know about Checking M1 Garand Head Space.” We recommend all Garand shooters read the article.
McClean explains: “Excessive headspace will cause the brass to stretch more than it should and increases the likelihood of a case failure. Insufficient headspace may contribute to slam fires, light strikes on primers, misfires and more wear on parts due to the additional force needed to chamber the rounds.”
Garand Head Space Gauges
McClean writes: “Both Forster and Clymer make fine gauges but we have found that there are differences between the two companies’ gauges that make the Clymer gauges best for use with the M1. The headspace that the original manufacturers of the M1 considered correct can be determined by checking new or nearly new rifles that we have here at CMP. With that information we have determined that Springfield Armory and the other manufacturers of the M1 used gauges that were very close to the Clymer dimensions… and therefore we use, and recommend using only the Clymer gauges.”
How to Check for Proper Headspace
In the article, McClean goes on to show how to properly use the “GO”, “NO GO”, and “FIELD” gauges. You’ll want to read the Complete Article. One of the important points McClean makes is that the ejector can affect headspace reading. Accordingly, “the bolt must be disassembled and the ejector removed, or clearance notches must be made on the headspace gauges so there will be no contact between the headspace gauges and the ejector.”
After purchasing a new set of dies from Forster, Hornady, Redding, or Whidden Gunworks, you’ll want to disassemble the dies, inspect then, and then remove the internal grease and/or waxy coatings placed on the dies by the manufacturer. This short video from Hornady shows how to de-grease and clean dies as they come “out of the box” from the manufacturer. A convenient aerosol spray cleaner is used in the video. You an also use a liquid solvent with soft nylon brush, and cotton patches. NOTE: After cleaning you may want to apply a light grease to the external threads of your dies.
Clean Your Sizing Dies and Body Dies Regularly
These same techniques work for cleaning dies after they have been used for reloading. Many otherwise smart hand-loaders forget to clean the inside of their dies, allowing old case lube, gunk, carbon residue, and other contaminants to build up inside the die. You should clean your dies fairly often, particularly if you do not tumble or ultrasound your cases between loadings. It is most important to keep full-length sizing and body dies clean. These dies accumulate lube and carbon residue quickly.

Sergeant First Class (SFC) Keith Sanderson of the U.S. Army Reserve has been crowned the 2015 NRA National Pistol Champion. After six wet days at Camp Perry along the shores of Lake Erie, Sanderson unseated defending champion Brian Zins by 14 points – 2655 to 2641.
Sanderson, who served eight years in the Marine Corps and eight years in the U.S. Army, is a renowned sport shooter who holds an Olympic record and won an unprecedented three medals (gold, silver, and bronze) in three World Cups in 2009.
Wet Conditions at Camp Perry this Year
At Camp Perry, you can always expect a little rain to come off the lake, but the midwest is experiencing torrential storms this summer and parts of the range – especially along the firing line – became flooded ponds. This year some shooters even stuck “No Wake” signs in the larger puddles to keep attitudes light despite the muddy situation.
Some competitors wore rubber boots to help navigate the puddles.

The Swarovski Optik website features a blog with interesting technical articles. In the “On Target” series of blog stories, Swarovski has provided a handy explanation of how optics systems work, with exploded diagrams of rifle scopes, spotting scopes, and binoculars. CLICK HERE for Swarovski Optics Blog.
Scope Terminology Focusing Lens
The focusing lens is an adjustable lens inside the optical system for focusing the image at different distances…. In the case of rifle scopes, apart from focusing, the focusing lens also facilitates parallax compensation.
For rifle scopes, the reticle can be focused using the diopter adjustment on the eyepiece, thereby correcting any visual impairment. [Editor’s Note: Movable eyepiece diopter adjustment is not offered on all rifle scopes. It is a useful feature on Swarovski and other premium scopes. This allows shooters who need eyeglasses to get a sharply focus image even without wearing corrective lenses. Of course shooters should always wear ANSI-certified eye protection. With the diopter, folks who need correction can use inexpensive, non-Rx safety eyewear instead of expensive prescription safety glasses.]
The purpose of the reversal system is to reverse the image by means of prisms in binoculars and telescopes, and lenses in rifle scopes….The lens reversal system is needed in rifle scopes to control the variable magnification and move the exit pupil[.]

Shooting really well with a lightweight bipod requires good technique. One thing you want to do with most field-style bipods is to “pre-load” the bipod with forward pressure. In a helpful “how-to” article, Accuracy-Tech Blog Editor Rich offers some good advice on bipod technique, explaining how to pre-load your bipod before each shot. Hunters and practical/tactical shooters may want to read this article.*
Rich explains: “The purpose of loading a bipod is to take any and all slack out of the shooter and rifle system. If the shooter … doesn’t have a solid position behind the rifle it will jump around more.” With good technique and a solid position, Rich explains, you should be able to tame the recoil pulse and eliminate the dread “bipod hop” which can force you to re-establish your position.
Rich offers two methods to load the bipod before each shot:
“Method number one is to get into position behind the gun, bring the stock up to your shoulder and relax. Then slowly, pressing off the tips of your big toes with your feet, shimmy your entire body as a unit forward slightly against the rifle. You don’t want to move it, you just want to put a little pressure against it.”
“The second method is to get into position, and then lift your chest up off the ground with the muscles in your back. You want to do a little sea otter impression here. As you lift your trunk up slightly, pull the rifle stock up into your shoulder pocket. Then as you relax push the gun forward in front of you but stop short of removing all the forward pressure against the rifle. If you push too far it won’t have any pressure against it. You don’t have to make large movements here, just a small lift, pull the rifle in, then relax back against the gun.”
Here’s a video of Rich shooting from bipod. You can see how his Atlas Bipod is pre-loaded. Watch how the gun recoils with no “bipod hop”. Rich shows very good form on the gun with smooth follow-though. Regarding follow-through, Rich says: “Don’t slap the trigger, don’t play gopher head[.] You want to remain motionless behind the rifle until the recoil impulse is over. If you lift your head between shots on the same target, you are hurting your chances of making a hit on subsequent shots.”
* The techniques recommended here are for lightweight, field-type bipods such as the Harris and Atlas models. You may want to use a completely different technique with large, wide-track F-TR and joystick bipods, allowing them to slide backwards on their sled feet during recoil.

How do you build better (more precise) ammo drop tables? With radar, that’s how. Barnes Bullets is using Doppler Radar to develop the drop tables for its new Precision Match line of factory ammunition. The Doppler radar allows Barnes to determine actual velocities at hundreds of points along a bullet’s flight path. This provides a more complete view of the ballistics “behavior” of the bullet, particularly at long range. Using Doppler radar, Barnes has learned that neither the G1 nor G7 BC models are perfect. Barnes essentially builds a custom drag curve for each bullet using Doppler radar findings.
Use of Doppler Radar to Generate Trajectory Solutions
by Barnes Bullets, LLC
Typical trajectory tables are generated by measuring only two values: muzzle velocity, and either time-of-flight to a downrange target, or a second downrange velocity. Depending on the test facility where this data is gathered, that downrange target or chronograph may only be 100 to 300 yards from the muzzle. These values are used to calculate the Ballistic Coefficient (BC value) of the bullet, and the BC value is then referenced to a standardized drag curve such as G1 or G7 to generate the trajectory table.
This approach works reasonably well for the distances encountered in most hunting and target shooting conditions, but breaks down rapidly for long range work. It’s really an archaic approach based on artillery firings conducted in the late 1800s and computational techniques developed before the advent of modern computers.
There is a better approach which has been utilized by modern militaries around the world for many years to generate very precise firing solutions. Due to the sizeable investment required, it has been slow to make its way into the commercial market. This modern approach is to use a Doppler radar system to gather thousands of data points as a bullet flies downrange. This radar data is used to generate a bullet specific drag curve, and then fed into a modern 6 Degree of Freedom (DOF) [ballistics software program] to generate precise firing solutions and greatly increase first-round hit probability. (The 6 DOF software accounts for x, y, and z position along with the bullet’s pitch, yaw, and roll rates.)
Barnes has invested heavily in this modern approach. Our Doppler radar system can track bullets out to 1500 meters, recording the velocity and time of flight of that bullet every few feet along the flight path. Consider the graph below showing a bullet specific drag curve referenced to the more common G1 and G7 curves:
Neither of the standard curves is a particularly good match to our test bullet. In the legacy approach to generating a downrange trajectory table, the BC value is in effect a multiplier or a fudge factor that’s used to shift the drag curve of the test bullet to try and approximate one of the standard curves. This leads to heated arguments as to which of the standardized drag curves is a better fit, or if multiple BC values should be used to better approximate the standard curve (e.g., use one BC value when the velocity is between Mach 1 and Mach 2, and a different BC value when the velocity is between Mach 2 and Mach 3.) Barnes’ approach to creating trajectory tables is to generate bullet-specific drag curves, and use that data directly in a modern, state-of-the-art, 6 DOF ballistics program called Prodas to generate the firing solution.

There is one subject as to which we should all be in agreement — the need to wear quality, protective eyewear whenever one uses a firearm. Sadly, it’s not uncommon, at the range, to see shooters wearing no eye protection, or wearing cheap, “dime-store” glasses that can shatter on impact.
This video from Luckygunner Labs shows what can happen with low-quality eyewear. When hit with pellets, the left lens came out and the right lens entered the eye socket!
Read Our Guide to Protective Eyewear
We’ve created a comprehensive Guide to Protective Eyewear. Forum member ChuckW2 told us: “That was the most important article that has ever been posted on this site. I am amazed how many people do not wear glasses while shooting or hunting. Great read….” If you haven’t done so already, read the story. We guarantee you’ll learn something new.
The Eyewear Guide explains the safety standards that apply to protective eyewear and reviews the best lens materials currently available including Polycarbonate, Trivex™, and SR-91. You may not have heard of Trivex, but it is probably the best material out there right now — it’s tough, lightweight, and has better optical properties than Polycarbonate. SR-91 is a good choice for those who need a polarized lens. Our Eyewear Guide also includes a section by Danny Reever on Prescription Shooting Glasses. Danny discusses the available options in lens materials and has many helpful recommendations.
Along with our reviews of lens materials, tint properties, and frame design, we highlight a study done by the NRA’s American Hunter magazine. 10 popular brands of eyewear were tested, with some very interesting results. The testers observed that price does not necessarily assure quality. Relatively inexpensive Bollé VX and Pyramex eyewear both worked better than some expensive brands.
On the other hand, don’t select eyewear simply because it’s cheap or easy to find. American Hunter editor Jeff Johnston observed: “It’s a mistake to assume that any plastic-lens sunglasses off the rack at the local 7-11 are made of polycarbonate and therefore are effective as shooting glasses—cheap plastics are not polycarbonates; in fact, wearing them could be worse than wearing nothing, as they can introduce sharp shards of plastic to your eyes in addition to the projectile(s) that caused them to break.”

Pro shooter Kirsten Joy Weiss demonstrates the SCATT MX-02 electronic training system:
The system traces and records valuable information such as hold pattern, shot hold duration, follow-through, recoil pattern, and much more. The latest SCATT MX-02 systems can be used both indoors and outdoors up to 300 meters (and possibly more). READ FULL SCATT MX-02 TEST HERE.
SCATT traces reveal muzzle movements during the aiming process.
Kirsten Joy Weiss, a top-level competitive position shooter, has tested the latest SCATT MX-02 training systtem. She put the MX-02 through its paces, and then produced an informative video that shows how it works. Click on the video above to see Kirsten use the MX-02 with her Anschütz rifle and other guns.
Kirsten was impressed with the SCATT MX-02 she tested:
“We live with tech woven into our every day, so if you had the chance to work with a computer to make you a better shooter — would you? Can a computer train you as well as your favorite coach or, dare to say, better than a human?”
Weiss says it’s like having a little coach with you recording your every move. “If R2D2 had a cousin who knew how to shoot,” Weiss quips, “his name would be the MX-02″.
The SCATT MX-02 can also be used with target pistols.
