For folks in the gun industry, the third Monday in January is the best day of the year. Held in conjunction with SHOT Show, Industry Day at the Range lets us try out dozens of new rifles and pistols, as well as meet top gun designers and friends in the shooting sports. We saw some very great new products this year. Here are some of the most interesting “take-aways” from Industry Day at the Range, held in Bolder City, Nevada on January 21, 2019.
New Guns + Old Friends
Meeting old friends, and shooting new guns. That’s what Monday was all about at the annual Industry Day at the Range, a “hands-on” preview the day before SHOT Show opens in Las Vegas. Your Editor met with old buddy Jason Baney and Hunting Editor Colton Reid at the crack of dawn and headed out to the Boulder City (NV) range.
We were not disappointed — there was plenty to see this year. On display were a bunch of new precision rifles, a slew of new handguns, and some very exotic optics (including a turretless digital camera/riflesight).
Cool New Rifles and Chassis Systems
Our friend Stan Pate let us try out Savage’s latest, greatest Modern Sporting Rifle, the MSR 10 Precision. Offered in 6mm Creedmoor, 6.5 Creedmoor, and .308 Win, this quality rig has many distinctive features, including side-charging handle, adjustable gas system, and convertible dual-angle pistol grip. This rifle proved exceptionally accurate on steel out to 400 yards. It is certainly one of the best AR10-class rifles we’ve tried.
Report from 6.5 Guys
Our good friends the 6.5 Guys (www.65guys.com) kicked off their 5th year of SHOT Show coverage at the Industry Day at the Range. At this event one can check out the latest firearms, putting guns through their paces with live fire demos. Here are two items that caught the eyes of the 6.5 Guys:
PGW Defense Timberwolf
The PGW Defense Timberwolf rifle in .338 Lapua Magnum proved to be a relatively light-recoiling rifle considering the cartridge and overall rifle weight of 14.5 pounds. Even with gusting 7:00 o’clock side winds (with 20+ mph peaks), hitting targets at 1,000 yards was very doable — a reminder of what the .338 Lapua can deliver. Impressive rifle.
Oryx Chassis for Howa, Rem, Tikka, Ruger, and Savage
Oryx (an MDT brand) has introduced a chassis system for Howa, Remington, Tikka, Ruger and Savage actions that retails for $399. While it comes with a grip, the user can bolt on standard AR-15 grips. This affordable system comes with an adjustable cheek piece and length of pull.

Optics — New 7-35x56mm Leupold + Radical Israeli Sensight
Leupold showcased an impressive new scope that should interest F-Class and PRS shooters. Leupold’s new 7-35x56mm Mark 5HD optic had very good glass, and positive controls. At 33 ounces, it is quite a bit lighter than other scopes in this class. We don’t have exact pricing yet, but it should be much less expensive than a Nightforce ATACR scope with the same magnification range.
New Leupold 7-35x56mm Mark 5HD
The new 7-35X Leupold models will be available with either milrad or MOA adjustments and advanced reticles. The milliradian models will be available in six reticle options: H-59, CCH, TMR, Tremor 3, and Tremor 3 Illuminated. The MOA version will be available with an Impact 60 MOA reticle.
Sensight SSR400 digital Riflesight
A big step forward in digital optics is Sensight’s new SSR400 Digital Riflesight, basically a high-resolution digital camera with a microprocessor-controlled reticle. The system is self-contained in a lightweight, compact display that allows the firearm to be held and used as if it held a traditional rifle scope. The digital interface allows users to customize the display, record video, and even livestream the image. The display eliminates eye relief issues, making it easy to acquire targets at distances up to 400 yards. Beyond 400 yards the image becomes noticeably pixelated, but still allowed us to easily hit targets at that distance. The price is moderate.
We viewed hundreds of pistols, shot a dozen or so, and came away with four we really liked. Two were suppressed rimfire pistols, and two were centerfire “Race guns”.
Ruger .22 LR MARK IV 22/25 Gold With Suppressor
We had fun trying out the Ruger MARK IV™ 22/45™ LITE fitted with a factory suppressor. Ruger had a new “bling” version on hand for test shooting. This was the Model 43926, with gold anodized aluminum upper receiver. This is ported for lightness — this pistol weighs just 25 ounces (without suppressor).
KelTec CP33 Suppressed Rimfire Pistol
We shot a very impressive KelTec pistol derived from the KelTec CMR-30 .22 WMR carbine. This new CP33 pistol is mostly the same as the CMR-30, but with no stock and a different front section. The 33 in the name refers to the fact that the clear magazine holds 33 rounds of .22 LR ammo. The version we shot was suppressed, and it was a pleasure to shoot. The trigger is excellent — noticeably better than most other 22s on the market. With virtually no recoil, it was ultra-quiet and surprisingly accurate. This Editor was surprised that a KelTec was one of his favorite new handguns at Industry Day. KelTec says the first production run should start shipping in March, 2019.
Walther PPQ Q5 Match SF (Steel Frame)
Walther’s PPQ Q5 has been popular with action pistol competitors. Now Walther offers an enhanced SF (“Steel Frame”) version. We like how the pistol balances with the heavier, beefier steel frame. We expect the extra mass of the steel frame will also reduce muzzle flip and perceived recoil. This is available from Walther with iron sights or a Red Dot.
Bul Armory SAS 1911-Type Race Gun
Israel’s Bul Armory offers a wide range of defensive handguns and target pistols, including the SAS series of competition pistols. These impressive “Race Guns” feature compensators, relieved slides, flared magwells, and excellent match triggers. Needless to say these comp pistols are a hoot to shot — with superfast cycle rates for fast shot transitions.

Ammunition — Big News from Sierra and More
Sierra Will Offer Loaded Ammunition
The big news in the world of commercial ammunitions come from Sierra bullets. For the first time, Sierra will be offering Sierra-branded loaded ammo. Our good friend (and multi-time Nat’l Long Range Champion) Michelle Gallagher revealed that Sierra will offer a selection of high-quality factory ammunition in 2019.
Sierra will be releasing its own brand of hunting ammunition. Sierra “Gamechanger” will debut in five popular hunting calibers: .243 Win, 6mm Creedmoor, 6.5 Creedmoor, .270 Win, and .308 Win. The rounds use a new tipped GameKing bullet for match grade accuracy in a hunting round. No details yet on brass, primer, and powder components for this ammo, but if the quality of the bullets is any indication these rounds will serve hunters well.
New Norma Monolithic Hollow Point Ammo
Norma unveiled some impressive new pistol ammunition. The new MHP (Monolithic Hollow Point) offers extreme expansion with major energy transfer. This MHP bullet features a lead-free solid core. This new MHP ammo offers serious performance for regions where lead-core bullets are prohibited. Accuracy is also very good with these new Norma bullets.
Great Products for Hunters and Varminters
We saw some impressive gear for game hunters and varminters. Swagger bipods has introduced a new kind of rifle support that combines the best qualities of both a field bipod and shooting sticks. And we saw a nice swivel field bench that offered very good stability.
Swagger demonstrated its new Stalker QD42 (quick detach) and Stalker Lite bipods. The QD42 is a lighter, more compact design of the already-established hunter series that allows for fast attach and removal via the push of a button. The quick attach/detach is a great feature that allows hunters to carry the bipod in their pack until it’s time to shoot. The Stalker Lite offers similar advantages in that it is extremely light and folds up like tent poles so it can be carried in a pack or side pocket. Both systems demonstrate the maneuverability swagger is known for and are reasonably priced.
Many Industry Day exhibitors were using the well-made and versatile DOA Shooting Bench. These benches feature a strong steel base supporting a very stable top that rotates to change rifle aim points in seconds. In addition, the DOA bench features a swivel seat. We liked the build quality on these DOA benches. Varmint hunters would like this bench — it would work well in a prairie dog field.
About Industry Day and the Range
With two dozen shooting bays, plus an elevated shooting station with targets out to 400 yards, there is plenty of action. Here’s the layout:
We definitely need to remember why we are able to continue to own and shoot firearms in this nation…
Next best thing to being there — this 5-minute video, produced last year, shows Industry Day highlights. It’s a great overview featuring a wide variety of rifles, pistols and shotguns. The biggest commercial, hands-on “live fire” gun demonstration in the world, Industry Day at the Range is attended by over 1700 journalists and buyers.
In this video, Forum member Erik Cortina shows how to create a custom modified case for use with the Hornady Lock-N-Load Overall Length Gauge (formerly the Stoney Point Tool). While Hornady sells modified cases for many standard cartridges, if you shoot a wildcat such as the 6mm Dasher or .284 Shehane, you’ll need to create a custom modified case*. And even if you shoot a standard cartridge such as the .308 Winchester you can get more consistent measurements if you make a custom modified case from a piece of brass fired in your chamber.
The process is straight-forward. Take a piece of brass fired in your chamber and full-length size it (with about .002″ shoulder bump). Then you need to drill out the primer pocket. Erik uses a mini-lathe for the operation, but this general process can be done with a drill press or other tools. Erik shows how to do this with a 0.290″ HSS (High Speed Steel) drill bit on a mini-lathe. After drilling the hole comes the tricky part — you need to tap the case with the precise 5/16″ x 36 threads per inch (tpi) right-hand thread that matches the male thread on the O.A.L. Gauge. This 5/16″ x 36 tpi tap is pretty uncommon, but you can order it from Amazon.com if you can’t source it locally.
If you use a mini-lathe, Erik suggests loosening the tailstock slightly, so it can float while cutting the threads. Erik also says: “Make sure you get the tap on pretty tight — it’s going to want to spin.” Erik turns the case at about 100 rpm when tapping the threads. Once the case and tap are rigged, the actual tapping process (see video at 6:00) takes only a few seconds. While the mini-lathe makes the tapping process go more quickly, the threading can also be done with other systems.
TIP: Don’t just make one modified case, make three. That gives you one for your range kit, one for your home reloading bench, plus a spare (since you WILL eventually lose or misplace one).
Here’s the Stuff You Need
5/16″-36 TPI Threading Tap
The required thread is somewhat uncommon. You need a 5/16″ – 36 tpi Right Hand Thread Tap. If you can’t find it locally, Amazon.com carries the correct tap. Erik notes: “The 5/16-36 tpi tap is not a common size. I think Hornady did this on purpose to make it more difficult for the average guy to make his own modified cases.”
0.290″ Drill Bit
Erik uses an 0.290″ HSS “L” drill bit. (This “L” Letter Gauge code designates a 0.290″ diameter bit). A close metric equivalent would be 7.3 mm (0.286″). Erik says: “A 9/32″ drill will also work but it will be harder to run the tap in since the hole will be .281″ instead of .290″ with the Letter Gauge L bit.”
Tips for Using O.A.L. Gauge with Modified Case
We’ve noticed that many folks have trouble getting reliable, consistent results when they first start using the Hornady O.A.L. Gauge (formerly the Stoney Point Tool). We’ve found this is usually because they don’t seat the modified case properly and because they don’t use a gentle, consistent method of advancing the bullet until it just kisses the lands.
Here is our suggested procedure for use the O.A.L. Gauge. Following this method we can typically make three of four measurements (with the same bullet), all within .001″ to .0015″. (Yes, we always measure multiple times.)
1. Clean your chamber so there is no build-up of carbon, debris, or lube. Pay particular attention to the shoulder area.
2. Screw the modified case on to the O.A.L. Gauge. Make sure it is seated firmly (and doesn’t spin loose). Note, you may have to re-tighten the modified case after insertion in the chamber.
3. Place your selected bullet so that the ogive (max bullet diameter) is behind the case mouth. This prevents the bullet from “snagging” as you insert the tool in the action.
4. Insert the O.A.L. Gauge into your chamber smoothly. Push a little until you feel resistance. IMPORTANT — You need to ensure that the shoulder of the modified case is seated firmly against the front of your chamber. You may have to wiggle and twist the tool slightly. If you do not have the modified case seated all the way in, you will NOT get a valid measurement.
5. Advance the bullet slowly. (NOTE: This is the most important aspect for consistency!). Push the rod of the O.A.L. tool gently towards the chamber. DON’T shove it hard! Easy does it. Stop when you feel resistance.
6. IMPORTANT. After gently pushing on the rod, give the end of the rod a couple forward taps with your finger. If your bullet was slightly skewed, it may have stopped too far back. Adding a couple extra taps will fix that. If the bullet moves after the taps, then again push gently on the rod. NOT too much! You just want to push the bullet until it just “kisses” the lands and then stops. Do NOT jam the bullet into the rifling. If you do that you will never get consistent results from one measurement to the next.
* For a $15.00 fee, Hornady will make a custom modified case for you if you send two fired pieces of brass. Send two fired cases and $15.00 check to: Hornady Manufacturing, Attn: Modified Cases, 108 S. Apollo St., Alda, NE 68810. More Info HERE.
With barrels, one wonders “Can a little more length provide a meaningful velocity gain?” To answer that question, Rifleshooter.com performed an interesting test, cutting a .308 Win barrel from 28″ all the way down to 16.5″. The cuts were made in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .308 Win factory ammunition were chronographed at each barrel length.
Test Barrel Lost 22.7 FPS Per Inch (.308 Win Chambering)
How much velocity do you think was lost, on average, for each 1″ reduction in barrel length? The answer may surprise you. With a barrel reduction from 28″ to 16.5″, the average speed loss of the four types of .308 ammo was 261 fps total. That works out to an average loss of 22.7 fps per inch. This chart shows velocity changes for all four ammo varieties:
Summary of Findings: The average velocity loss per inch, for all four ammo types combined, was 22.7 FPS. By ammo type, the average loss per inch was: 24.6 (Win 147 FMJ), 22.8 (IMI 150 FMJ), 20.9 (Fed GMM 168gr), and 22.5 (Win 180PP).
Interestingly, these numbers jive pretty well with estimates found in reloading manuals. The testers observed: “The Berger Reloading manual says for the 308 Winchester, ‘muzzle velocity will increase (or decrease) by approximately 20 fps per inch from a standard 24″ barrel’.”
How the Test Was Done
The testers described their procedure as follows: “Ballistic data was gathered using a Magnetospeed barrel mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Since we would be gathering data on 52 different barrel length and ammunition combinations and would not be crowning the barrel after each cut, we decided to eliminate gathering data on group sizes. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 47° F.”
CLICK HERE to Read the Rifleshooter.com Test. This includes detailed charts with inch-by-inch velocity numbers, multiple line charts, and complete data sets for each type of ammo. Rifleshooter.com also offers ballistics graphs showing trajectories with different barrel lengths. All in all, this was a very thorough test by the folks at RifleShooter.com.
Much Different Results with 6mmBR and a Longer Barrel
The results from Rifleshooter.com’s .308 barrel cut-down test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33″ to 28″, we only lost about 8 FPS per inch. Obviously this is a different cartridge type, but also our 6mmBR barrel end length was 5″ longer than Rifleshooter.com’s .308 Win start length. Velocity loss can be more extreme with shorter barrel lengths (and bigger cartridges). Powder burn rates can also make a difference.

Some years ago, the folks at TargetWorkz published a a handy set of plans for a 48-inch tall self-supporting target stand. This makes a great do-it-yourself project. To create a sturdy, self-supporting target frame, all you need are some 2x4s, 1x2x48 furring strips, plus fasteners. The target holder, which supports an 18×24 inch cardboard target backer, separates from the base for easy transport.
Note: There is no cross-piece shown in the plan, but we do recommend putting wood crosspieces at the top of the target stand and about 18″ up from the bottom. This will make the frame more rigid, and will allow the frame to work even if the cardboard is badly “shot up”. Use a T-square to set the crosspieces before attaching them with screws.
Alternative Target Stand May from ABS or PVC Pipe
If you like this kind of project, but want to build a frame that is taller, yet can break down into sections, we also have an article showing you how to build a nice frame with inexpensive ABS or PVC tubing. VIEW ABS/PVC Tubing Target Frame Plans.
The new .224 Valkyrie for AR15-platform rifles has garnered lots of attention lately. That new cartridge has gotten people thinking about the options for an AR shooter beyond the venerable .223 Remington (and 5.56x39mm NATO). While the .224 Valkyrie is good for shooting long heavy bullets (such as Sierra’s new 95gr SMK), there is a simpler, cheaper option for folks who favor “fast and light” — smaller, lower-mass bullets traveling at very high velocities. That option is the 20 Practical, which is simply a .223 Remington necked down to 20 caliber. This little cartridge can launch 40-grainers at over 3900 fps. That’s bookin’. This makes the 20 Practical a great choice for an AR-based varmint rifle.
20 Practical Ultimate Varminter
A decade ago, as a “proof-of-concept”, AccurateShooter.com created a 20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. That gun was auctioned off, but Robert Whitley continues to produce custom 20 Practical AR15 uppers. (The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard.223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.)
Robert reports that the accuracy of the first 20 Practical AR15 was no fluke. After building six (6) more 20 Practical uppers, he tested them for accuracy and they all shot great. These uppers feature DPMS low-pro receivers with side charging handles. They are fitted with PacNor 1:11″ twist, three-groove stainless barrels.
Robert reports: “We have been making more 20 Practical AR15 uppers and I have to say I am astounded by the accuracy of these things. For shooting little tiny groups out of an AR15 with bullets going 3500+ fps, it’s hard to beat the 20 Practical. Today I test-fired six more uppers, all with 11-twist barrels. Three of the uppers had 24″ barrels, two had 20″ barrels, and one had an 18″ barrel (we call it ‘Stubby’).
In four of these uppers I shot re-sized Winchester brass using 25.3 grains of WC844 powder with Berger 40gr BTHP bullets loaded at 2.225″ OAL (about .015″ off the lands). WC844 is inexpensive military surplus powder that is nearly identical to H335. I tried three different primers and the choice did not seem to matter (CCI BR4, Rem 7 1/2s and Win Small Rifle — the old silver ones). All these four uppers shot great. Here is an animated GIF with targets from uppers #6, 10, and 11. All groups are mag-fed, 5-shot groups shot at 100 yards using a front rest and rear bag.”
Targets Shot with Three Different 20 Practical AR Uppers

How well can the little 6mm Dasher perform at 1000 yards when the conditions are good, and the shooter is riding a hot streak? Well here’s a shot-by-shot record of Scott Nix’s 4.554″ ten-shot group shot at Missoula, Montana at the Northwest 1000-yard Championship a few years back. All 10 shots were centered for a 100-6X score. That’s about as good as it gets. If Scott had stopped after 5 shots, his group would have been under three inches.
Video Demonstrates Amazing 1000-Yard Accuracy
Watch the video. You can see the group form up, shot by shot. It’s pretty amazing. Scott’s first shot (at the 45-second mark of the video) was right in the X-Ring, and four of Scott’s first five shots were Xs. That’s drilling them! This video was recorded from the pits at the 1000-yard line, during record fire.
Next time you have a barrel fitted, consider having your gunsmith create a “stub gauge” from a left-over piece of barrel steel (ideally taken from your new barrel blank). The outside diameter isn’t important — the key thing is that the stub gauge is created with the same reamer used to chamber your current barrel, and the stub must have the same bore diameter, with the same land/groove configuration, as the barrel on your rifle. When properly made, a stub gauge gives you an accurate three-dimensional model of the upper section of your chamber and throat. This comes in handy when you need to bump your case shoulders. Just slide a fired case (with spent primer removed) in the stub gauge and measure from base of case to the end of the gauge. Then, after bumping, re-measure to confirm how much you’ve moved the shoulder.
In addition, the stub gauge lets you measure the original length to lands and freebore when your barrel was new. This gives you a baseline to accurately assess how far your throat erodes with use. Of course, as the throat wears, to get true length-to-lands dimension, you need take your measurement using your actual barrel. The barrel stub gauge helps you set the initial bullet seating depth. Seating depth is then adjusted accordingly, based on observed throat erosion, or your preferred seating depth.
Forum member RussT explains: “My gunsmith [makes a stub gauge] for me on every barrel now. I order a barrel an inch longer and that gives him enough material when he cuts off the end to give me a nice case gauge. Though I don’t have him cut that nice-looking window in the side (as shown in photos). That’s a neat option. You can tell how much throat erosion you are getting from when it was new as well. For measuring initial seating depths, this is the most useful item on my loading bench next to calipers. Everyone should have a case gauge made by their smith if you have a new barrel put on.”
Forum member Lawrence H. has stub gauges made with his chamber reamers for each new barrel He has his smith cut a port in the stub steel so Lawrence can actually see how the bullet engages the rifling in a newly-cut chamber. With this “view port”, one can also see how the case-neck fits in the chamber. Lawrence tells us: “My stub gauges are made from my barrels and cut with my chamber reamers. With them I can measure where my bullets are ‘touching the lands’ and shoulder bump dimensions. This is a very simple tool that provides accurate information.” The photos in this article show the stub gauges made for Lawrence by his gunsmith.
There’s a formidable new option for PRS Production Class. MasterPiece Arms (MPA) is bringing out a new tactical/practicalcompetition rig, officially called the MPA BA PMR Competition Rifle. This new rifle has a $1999.99 price tag, making it suitable for Production Class. It will be offered with Curtis Action fitted to an X-Caliber, hand-lapped 26″ match barrel. Three chamberings will be available: 6mm Creedmoor, 6.5 Creedmoor and .308 Winchester.
This rifle is designed specifically for the Production Class requirements of the Precision Rifle Series (PRS) and has been approved for use within this division. It includes many competition-related features while staying under the $2,000 price limit for this class. It is available in either a Black or Tungsten Cerakote® finish. Accuracy is helped with a very good barrel — an X-Caliber, hand-lapped 416R Stainless premium barrel with a polished finish. The chamber is indicated within 0.0001” or less to the bore of the rifle.
The MPA BA PMR Competition Rifle utilizes the MPA BA Ultra Lite Chassis, CNC-machined from 6061 aluminum. The V-bedding system provides additional clearance for glass bedding action and straight section of the barrel. The chassis also includes a built-in inclinometer, thumb notch, lower mounted Picatinny Rail, 20 MOA Scope Rail, A2 Style Pistol Grip and is R.A.T. System compatible. The MPA Buttstock comes with an adjustable cheek riser and length of pull that are locked in position with a series of set screws that are embedded into the buttstock body. This is the same system MPA uses on its Standard BA Chassis, but without the thumb wheels.
Here’s a “must-read” article for .22 LR rimfire shooters. The recently-released October 2018 issue of Shooting Sports USA (SSUSA) includes a great article with data on thirty-one (31) different types of popular .22 LR rimfire ammunition. The line-up includes low-speed, standard, and Hi-Velocity types, plus choices for plinking, varminting, and target applications. Brands tested include: Aguila, American Eagle, CCI, Federal, Fiocchi, Lapua, Remington, and Winchester. The slowest ammo, CCI Quiet-22 Lead RN, clocked 727 FPS. The fastest ammo, CCI Short-Range Green Lead-Free HP, ran 1735 FPS, more than twice as fast as the Quiet-22.
For each ammo type, SSUSA lists the bullet weight, velocity (FPS), and average of two, 5-shot groups at fifty yards. The most accurate ammo was Lapua Center-X LRN, with a 0.37″ average 50-yard group size. Second best was Lapua X-ACT LRN at 0.42″. Ammo was tested from a bench with a Cooper Model 57-M rifle fitted with 3-9x33mm Leupold VX-2 scope. The ammo offerings were grouped into three categories: (1) Varmints/Small Game; (2) Target; and (3) Plinking. (See ammo tables below.)

Different types of .22 LR (Long Rifle) rimfire ammo have different applications. Subsonic ammo, typically, is best for 25m to 50m target work with precision rimfire rigs. Hi-Velocity .22 LR ammo provides a flatter trajectory for longer ranges. SSUSA explains: “The array of .22 LR loads… turns a person’s head every which way. Subsonic target loads are the key to decisive accuracy on targets, while hyper-velocity cartridges provide striking bullet expansion on small varmints. In between, standard and high-velocity .22 LRs are loadrf with a variety of bullet weights and styles for everything from small-game hunting to plinking[.]” READ Full SSUSA .22 LR Rimfire Ammo Story.
20 Practical Ultimate Varminter
How well can the little 6mm Dasher perform at 1000 yards when the conditions are good, and the shooter is riding a hot streak? Well here’s a shot-by-shot record of Scott Nix’s 4.554″ ten-shot group shot at Missoula, Montana at the Northwest 1000-yard Championship a few years back. All 10 shots were centered for a 100-6X score. That’s about as good as it gets. If Scott had stopped after 5 shots, his group would have been under three inches.
