For load development, some guys shoot 3-shot groups. Other guys shoot 5-shot groups, or even 10-shot strings. But for testing its projectiles, Sierra Bullets takes it to another level entirely. A while back Sierra was testing its .30-Caliber 175gr HPBT MatchKing in the Sierra uynderground tunnel. The results are show above — a FIVE HUNDRED Round group!
The tunnel testers sent five full boxes of bullets down-range. Here are 500 Shots shot in a 300 meter tunnel. The group size is 2.82 inches (that’s edge to edge of the farthest shots, less the bullet diameter). This was a pressure/velocity test for a commercial customer. The Cartridge was .308 Win, loaded at 2.800″.The powder was Reloder 15. A 26″ barrel was shot from a return to battery rest. The gun was cleaned every 125 rounds and two foulers shot.
What do you think — could you beat this group from a bench for 500 rounds?
One Facebook poster joked: “500-round group? Everyone knows anything less than 1000-round groups are a waste of time and statistically irrelevant.”
Sierra’s 300 Meter Testing Tunnel
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 of its projectiles. Sierra’s 300-meter test range is the longest, manufacturer-owned underground bullet test facility in the world. Sierra offers free tours of the test tunnel as part of Sierra’s Factory Tour Program.

We’ve told fans of Hodgdon H4350 to give Alliant Reloder 16 (RL16) a try. In our tests, Reloder 16 has proven a very promising rival to H4350 for accuracy, low ES/SD, and temp stability.
Now you can get the advantages of Reloder 16 in a slower powder formulated for magnum cartridges — Reloder 26 (RL26). Alliant says RL26’s burn speed falls between that of Reloder® 22 and Reloder® 33. That means it’s slower than H4831 but faster than powders that would suit the .338 Lapua Magnum. Reloder 26 has a high bulk density that allows larger powder charges, and high velocities. RL26 also provides a consistent, controlled response to temperature changes.
We are hearing very good things about RL26 from friends and Forum members who are testing it with big calibers for Long Range applications. Accuracy is good and velocities are impressive. Alliant says RL26 “incorporates EI® technology to produce extremely high velocities in magnum cartridges”. In big magnums, shooters have reported gaining 100+ fps with RL26 compared to H1000 or Retumbo. And to our surprise some guys have even tried replacing H4350 with RL26 (in smaller cartridge types) and they have picked up meaningful velocities. We don’t think Alliant ever intended RL26 as a substitute for H4350, but if you’ve got the case capacity… it may be worth a try.
Alliant Reloder 26 Features
EI® technology delivers high velocities in magnum cartridges
Contains proprietary de-coppering additive
Controlled temperature stability
Excellent lot-to-lot consistency
Formulation contains no DNT or DBP
Made in Switzerland for Alliant Powder
Alliant’s Tech Expert Talks about Reloder 26
What are the characteristics of Reloder 26? That question was answered recently by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:
“Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they [it is] made by Bofors, so that is incorrect. I have also noticed people are equating … Reloder 26 to Reloder 25. Reloder 26 is definitely slower burning than Reloder 25, so there shouldn’t be any confusion there either.”
Speed and More Speed with RL 26
Think of Reloder 26 as a high-velocity powder for big cartridges. Furrier explains: “Reloder 26 is produced with Nitrochemie’s latest generation EI® process technology. This is the same impregnation coating process used to produce Reloder 17, Reloder 33, and Reloder 50 for us, and it is fantastic. Reloder 26 [offers] great ballistic efficiency, high bulk density so you can get more of the slow powder into the case to harness the energy, and decent, predictable extreme temp response. Reloder 26 is not as flat at temps as the TZ or Australian materials, but it is very manageable, usually in the 0.5 fps/°F range (depending on the application). Just as important, the pressure increases at hot are very manageable. We are using quite a bit of this RL26 powder in our Federal factory ammo due to the fantastic ballistics and accuracy.” — Paul Furrier, ATK

While “naked” bullets are just fine for most applications, some shooters like to put a friction-reducing coating on their projectiles. Coating bullets can benefit guys who run very high round counts between barrel cleanings. Reader Mike Etzel has come up with a simple, cost-effective way to apply HBN, Moly, or Danzac (WS2) coatings to your bullets. And you won’t need any expensive gear other than your regular vibratory tumbler and some small plastic containers.
Mike explains: “For a number of years I have been using a very convenient way of coating my projectiles with DANZAC in a tumbler. Instead of using a separate tumbler filled with DANZAC and stainless steel balls for coating applications, use small resealable plastic cake or pudding cups filled with stainless balls and DANZAC. Each cup will accommodate between 20 to 70 projectiles depending on caliber once the polishing balls and DANZAC are added. When I need to polish some cases, I insert the sealable plastic container(s) into the polishing material in the tumbler, add cases to the media, and in the process clean cases and coat the projectiles simultaneously in one tumbler. This does two operations in one session, saving on time and resources.”
While Mike uses DANZAC (Tungsten DiSulfide or WS2), you can use the same impact-tumbling method to moly-coat your bullets, or to apply HBN (Hexagonal Boron Nitride).
TIPS for COATING your BULLETS, by GS Arizona
1. Start with Clean Bullets. This is simple enough, but some people overlook it and others overdo it. Get the bullets out of the box, wash them with warm water and dish soap and dry them. No need for harsh chemicals, after all, we’re only removing some surface dirt from shipping and maybe some left over lanolin from the forming process. Don’t handle them with bare hands once they’re clean, your skin oils will contaminate them.
2. Get Everything Hot — Real Hot. This is probably the single most important element in producing good-looking moly-coated bullets. I put the tumbler, the drum and the bullets out in the sun for at least 30 minutes before starting and then do all the tumbling in direct sunlight. On a summer day in Arizona, everything gets to the point that its uncomfortably hot to handle. If you are tumbling in the winter, you should heat the bullets in some form, a hair dryer can be useful, but they will cool off in the drum if you’re tumbling in cold temperatures. Your best bet is to plan ahead and do your coating in the summer. I coated about 3000 bullets in a couple of days recently to see me through our winter season (we’re a bit reversed from the rest of the country in terms of shooting season).

High Power and F-Class shooters have a ton of gear they need to carry out to the firing lines. To do the hauling, you can certainly purchase a factory-made, purpose-built cart that folds up and has all the bells and whistles. The Creedmoor Sports CRC-1 (photo right) is a proven, quality product that works great. You’ll find these used by top shooters at Camp Perry. But the Creedmoor CRC-1 cart costs $499.95.
For a fraction of that price ($54.99), plus a few dollars more for do-it-yourself enhancements, you can have a heavy-duty cart that will haul all your gear just fine, though it doesn’t fold up. In the top photo is a Harbor Freight Welding Cart we saw at the Berger Southwest Nationals. This rig is carrying a rifle in hard gun case, bipod, folding chair, shooting mat, tripod, spotting scope, rear sand-bag, and ammo box — that’s a lot of gear!
Check out the Harbor Freight Welding Cart, item #65939. This cart is ON SALE right now for just $54.99. Overall size is 29-1/2″ L x 20″ W x 49″ H, and width between side rails is 18″. The wheels (with tires) are 20 3/4″ in diameter for smooth rolling. Consider that, if you made your own cart from scratch you could easily pay $30.00 or more just for the large-diameter wheels and axle. Do note — this cart has air-filled tires. Be sure to inflate before you go to the Range!
As sold, the Harbor Freight Welding Cart can benefit from upgrades for range use. But with a few bungee cords (and some creativity), the cart can be adapted pretty easily to hauling your gun gear. If you want to enhance the basic cart, it’s easy to add plastic side-panels on the bottom unit, and fit a barrel-holding system on the cross-tube. This ensures rifles and gear won’t flop forward. (A small piece of wood under the bottom panel provides a bit of extra lift that will keep the bottom plate out of the dirt and gravel.)

Shooting on a Golf Course is pretty cool. But do you have to yell “Fore!” prior to pulling the trigger?
Sean Murphy has a job we can envy. As Marketing Communications Manager for Nightforce Optics, Sean gets to shoot at major rifle competitions as part of his job. Sean recently attended the Long Range Shooting Experience (LRSE) Match at the RockCastle Shooting Center in Park City, Kentucky.
As part of the Precision Rifle Series (PRS), the LRSE match attracts many of the nation’s top tactical/practical shooters. The venue is a beautiful setting, more like an outdoor park than a typical gun range. In fact, Sean tells us: “I’ve long said a golf course is a waste of a perfectly good shooting range. One of the many reasons I love the LRSE match is getting to shoot rifles across the greens at Rockcastle.” Part of the LRSE match did indeed take shooters close to putting greens.
Yes that’s a putting green just ahead of the competitors. Use the blue golf flag to help call the wind!
Rockcastle Shooting Center is part of a 2000-acre outdoor playground. The shooting center is the “new” part of an old resort, which boasts a 100-room guest hotel and conference center, a restaurant with excellent food (and great views), a winery and 2-acre vineyard, and, yes, an 18-hole USGA golf course. It does look like a beautiful place to shoot. Nice to see that guns and golf can co-exist in Kentucky.
The Rockcastle Shooting Center is home to several different shooting clubs, and more than 50 competitions per year. CLICK HERE for more information.

At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.
1. Midsouth — Labradar Chronograph and Accessories
Midsouth Shooters Supply is now carrying the advanced Labradar chronograph. This unique unit allows you to measure your shots without having to set up a tripod and skyscreens downrange. When you start using a Labradar, you’ll never want to go back to old-style chronographs. You can also purchase the Labradar from Bruno Shooters Supply. Price is $559.95 from either vendor. NOTE: Very soon Labradar plans to offer Bluetooth functionality, allowing you to control the machine remotely with your mobile device. This functionality will come via new software — the Bluetooth transceiver is built-in to all current Labradar units, so you can buy one now and use Bluetooth later (when the software is released).
2. Natchez — Special 5 Reloading Press Kit, $199.99
This RCBS Kit has everything a new reloader needs: single-stage press, powder measure, scale, powder trickler, priming tool, cartridge tray, “rocket” chamfer tool, case lube and more. This is an excellent entry-level reloading kit, on sale for just $199.99 at Natchez Shooters Supplies. We like the relatively compact Special 5 press for most reloading duties. Eventually you may want to add an additional, large heavy press, but this will get the job done. For the combined package, with all the tools one needs to hand-load quality ammo — this is a stunningly good deal at $199.99.
3. CDNN — Browning Maple X-Bolt Medallion, $849.99 with Rebate
CDNN Sports has some of the nicest modern Browning rifles we’ve seen. These deluxe Maple-stocked X-Bolt Medallion Rifles are now on sale for $899.99, marked down from $1519.99. Plus, through March 31st, you can get another $50.00 off with a Browning Rebate. The machine-engraved receiver features a polished blued finish, and is glass bedded into the stock. The free-floating barrel is high-gloss blued, hand-chambered and finished with a target crown. The bolt has a 60° lift and the trigger is adjustable. The stock is a high gloss AAA maple with rosewood fore-end and pistol grip cap. These are very nice rifles that any shooter would be proud to own. This Editor has ordered one as a gift to a family member — that should say something.
4. Amazon — Ammo Can/Gun Case/Range Bag System, $44.99
This Plano 1612 X2 Range Bag System combines a plastic ammo can-type container with a two-pistol hardshell case, both enclosed in a durable, padded fabric cover with many pockets. This handy system lets you keep pistols in a separate locked compartment while still accessing ammo, muffs and other gear from the main compartment, which can also be secured with a padlock. This is a clever, versatile design, and owner reviews have been very positive:
“The perfect range bag. It comes with a nice gun case, more pockets than shown, plenty of storage for earphones, several boxes of ammo and room to spare. Would buy again!” — Nate K
“The problem with most range bags is that they are range ‘bags’. This is an ammo can with pockets for all your other gear. No more ‘saggy baggy’!” — MPowers
5. Sportsman’s Guide — 1000 Rds 9mm Ammo, $204.99 delivered
Everyone can use a 1000-round case of 9mm Luger Ammo. This Sellier & Bellot 124gr FMJ brass-cased ammo feeds and functions well. We’ve checked around and this $204.99/1000 price is one of the best deals on brass-cased 9mm ammo this week (for SG members, the cost is $194.99). Plus you can get FREE shipping with CODE SH2656 at checkout. We have shot this ammo in Glock, H&K, Sig Sauer, and S&W pistols. Rated at 1080 fps, this 9mm ammo was very reliable, and the boxer-primed cases are reloadable.
6. Cabelas — Simmons 20-60x60mm Spotter, $49.99 with Rebate
Let’s be realistic — this 20-60x60mm Simmons is NOT a great spotting scope. The sharpness is nowhere near as good as you’d get with a $1000+ spotter. However, you can now get this unit for under fifty bucks with manufacturer’s rebate. Cabela’s Sale Price is $59.99 and Vista Outdoor is offering a $10 Rebate. For basic work, such as viewing pistol targets, or spotting hits out to 250 yards, this bargain basement Simmons should suffice. Read the owner reviews — they have been surprisingly good. This scope will also work for general recreational use. Hard to beat for fifty bucks.
7. Amazon — 34 dB Noise Rating Ear Muffs, $17.45
These 34 dB NRR earmuffs provide excellent sound protection without being too heavy and bulky. At at $17.45, they are a great bargain. The lower section of the muff is trimmed for a narrower profile — that helps with rifle and shotgun stocks. The headband is adjustable and has comfortable padding. These Pro For Sho Muffs have earned a 4 1/2 star consumer rating, with over 1,600 Amazon customer reviews. NOTE: These fit pretty tight. If you have a very large hat size you might want a different brand.
Here’s a good deal on the new Lyman 50th Ed. Reloading Manual. Our Forum members have rated this as the best Loading Manual for starting hand-loaders. This 50th Edition, the first to be produced in full color, includes more load data, and covers more cartridges than ever before. New Cartridges Include: 17 Hornet, 6.5 Grendel, 6.5 Creedmoor, 6.5-284, 26 Nosler, 28 Nosler, 300 Blackout, 300 RCM, 338 RCM, 450 Bushmaster, 458 SOCOM, 50 Beowulf. Amazon has the Softcover version for $19.99 and Hardcover for $23.99. Notably, Lyman donates $1.00 to the NRA for every Lyman 50th Edition Reloading Handbook sold during the first year of publication.
9. Amazon — Neiko Digital Calipers, $16.45
Even if you have a good set of calipers, you may want to get one of these Neiko 01407A Digital Calipers. The #1 best-selling digital caliper on Amazon.com, this Neiko tool features a large LCD Screen and measures up to 6.0 inches. With over 2300 customer reviews, this product has earned an overall rating of 4.4 out of 5 stars. It’s hard to go wrong for $17.74, even if you just use these as a spare set for measuring group sizes and case trim lengths.

We liked (and used) Lyman’s Digital Trigger Pull Gauge before, and now it’s even better. Lyman has updated its pull gauge to be faster and more precise. The new gauge measures trigger pull weights from 1 ounce to 12 pounds with resolution of 0.1 ounces (2.8 grams). We think that anyone running match triggers below 2.5 pounds pull weight should have a gauge like this. Among the pull gauges on the market, we think the new Lyman unit now offers the best performance for the price — this gauge has a $59.95 MSRP, and expect to see it for under $50.00 when it is available. We like the new adjustable, 4-position rod which retracts into the gauge body.
Upgrades: More Precise Strain Gauge | Improved Grip Shape | Adjustable Rod Lengths
Lyman’s new, improved Electronic Digital Trigger Pull Gauge is designed to be the fastest and most accurate trigger pull gauge available. State-of-the-art strain gauge technology allows for repeatable accuracy of 1/10 ounce (2.8 grams). The gauge features a large, easy-to-read LCD display and you can switch from ounces to grams with the push of a button. The gauge can also deliver a pull weight average of the last 10 readings. That’s very helpful, particularly when working with factory triggers that may not be very consistent.
The new model Trigger Pull Gauge features a solid, collapsible rod with four locking positions. Being able to adjust length makes it easier to use the gauge with a wide variety of firearms. The locking feature prevents the rod from flexing when applying pressure to the trigger. When not in use, the rod conveniently collapses into the gauge body, making the whole unit more compact. The new Trigger Pull Gauge comes in an internally-padded plastic case that can be easily stored in a drawer or on your work bench. The old-style Lyman gauge (shown below) had a limited rod-length adjustment range, and the rod needed to be removed to store the gauge in its soft case.

CZ offers good “bang for the buck” in both rimfire and centerfire rifle line-ups. We’ve always liked the CZ 455 rimfire rifles — especially as fitted in Manners stocks. For 2017, CZ has introduced some interesting new options including a great looking new Model 557 Varmint rifle. Here we’ve embedded a couple videos that cover the new offerings. New CZ 2017 Firearms LINK.
New Model 557 Varmint
The new CZ Model 557 Varmint rifle features a new, ergonomic stock with a heavy contour 25.6″ barrel. The newly-designed walnut stock features a palm swell, laser-cut stippling, and a flat fore-end. This makes the rifle excellent for shooting off a bench with a front rest. The 557 Varmint is chambered in .308 Win or .243 Win. We suspect most purchasers will get the .243 Win version for use in the varmint fields. Note however, the 6mm barrel has a 1:10″ twist so you can’t shoot the heavier 95 to 110-grain 6mm bullets. Potentially, the .308 Win version could be a budget F-TR rifle, with the right bipod set-up up front. The 1:10″ twist of the .30-Cal barrel allows it to shoot bullets up to about 200 grains, making it suitable for long-range competitions.
CZ 455 Varmint Precision Trainer
The 455 Precision Trainer was designed to provide the same look and feel as a full-size tactical rifle while allowing for more economical training. Using a Manners Composite T4 stock, the Precision Trainer wears a new camouflage paint scheme this year. The stock itself has multiple layers of carbon fiber and fiberglass hand-laid in high temperature epoxy resins. This rifle is known for good accuracy, making it a good choice for target work as well as rimfire tactical games. This is offered in both 20″ and 24″ barrel versions. The 24-inch model has a heavy barrel that tapers to the muzzle, differing from the standard .866″-diameter Varmint barrel profile.
NEW .30-Caliber Model 527
The new Suppressor-Ready Model 527 is equally happy shooting steel or taking down hogs. Chambered in .300 Blackout or 7.62×39mm, it’s got enough knock-down power for small to medium-sized game at shorter ranges. Built on a short .223-length action, the CZ 527 features a classic American pattern stock, a sporter-weight, hammer-forged barrel, a single set trigger, and a recessed target crown. Made to be used with optics, the American version ships with 1″ steel scope rings.

Have you recently purchased a new scope? Then you should verify the actual click value of the turrets before you use the optic in competition (or on a long-range hunt). While a scope may have listed click values of 1/4-MOA, 1/8-MOA or 0.1 Mils, the reality may be slightly different. Many scopes have actual click values that are slightly higher or lower than the value claimed by the manufacturer. The small variance adds up when you click through a wide range of elevation.
In this video, Bryan Litz of Applied Ballistics shows how to verify your true click values using a “Tall Target Test”. The idea is to start at the bottom end of a vertical line, and then click up 30 MOA or so. Multiply the number of clicked MOA by 1.047 to get the claimed value in inches. For example, at 100 yards, 30 MOA is exactly 31.41 inches. Then measure the difference in your actual point of impact. If, for example, your point of impact is 33 inches, then you are getting more than the stated MOA with each click (assuming the target is positioned at exactly 100 yards).
How to Perform the Tall Target Test
The objective of the tall target test is to insure that your scope is giving you the proper amount of adjustment. For example, when you dial 30 MOA, are you really getting 30 MOA, or are you getting 28.5 or 31.2 MOA? The only way to be sure is to verify, don’t take it for granted! Knowing your scopes true click values insures that you can accurately apply a ballistic solution. In fact, many perceived inaccuracies of long range ballistics solutions are actually caused by the scopes not applying the intended adjustment. In order to verify your scope’s true movement and calculate a correction factor, follow the steps in the Tall Target Worksheet. This worksheet takes you thru the ‘calibration process’ including measuring true range to target and actual POI shift for a given scope adjustment. The goal is to calculate a correction factor that you can apply to a ballistic solution which accounts for the tracking error of your scope. For example, if you find your scope moves 7% more than it should, then you have to apply 7% less than the ballistic solution calls for to hit your target.
NOTE: When doing this test, don’t go for the maximum possible elevation. You don’t want to max out the elevation knob, running it to the top stop. Bryan Litz explains: “It’s good to avoid the extremes of adjustment when doing the tall target test.I don’t know how much different the clicks would be at the edges, but they’re not the same.”
Should You Perform a WIDE Target Test Too?
What about testing your windage clicks the same way, with a WIDE target test? Bryan Litz says that’s not really necessary: “The wide target test isn’t as important for a couple reasons. First, you typically don’t dial nearly as much wind as you do elevation. Second, your dialed windage is a guess to begin with; a moving average that’s different for every shot. Whereas you stand to gain a lot by nailing vertical down to the click, the same is not true of windage. If there’s a 5% error in your scope’s windage tracking, you’d never know it.”
Verifying Scope Level With Tall Target Test
Bryan says: “While setting up your Tall Target Test, you should also verify that your scope level is mounted and aligned properly. This is critical to insuring that you’ll have a long range horizontal zero when you dial on a bunch of elevation for long range shots. This is a requirement for all kinds of long range shooting. Without a properly-mounted scope level (verified on a Tall Target), you really can’t guarantee your horizontal zero at long range.”
NOTE: For ‘known-distance’ competition, this is the only mandatory part of the tall target test, since slight variations in elevation click-values are not that important once you’re centered “on target” at a known distance.
