We see comparison tests of cars, cameras, and other hardware. But how about chronographs? What could we learn by setting up three different chronographs, and running a 20-shot string over all three at the same time. One of our Forum members, Randy S. (aka AAA) did that very test with three of the best chronographs you can buy: LabRadar, MagnetoSpeed, and an Oehler model 35P. The MagnetoSpeed was attached to the barrel of an F-Class rig, with the LabRadar placed on the left side of the shooting bench. The Oehler 35P was positioned about 23 feet downrange. The photo above shows the set-up. A 20-shot string was recorded with the results in a spreadsheet.
AAA talks about this interesting experiment in a Shooters’ Forum Thread. Here is his report:
Comparison Testing Three Chronographs
We all have our favorite chronograph. Each gives a number, but how would that number compare to the same round fired with another chronograph? I wanted to know so a friend and I set up the following test with three chronographs: LabRadar, MagnetoSpeed V3, and Oehler Model 35P.
For the test we fired Berger 105gr VLDs over the three chronographs simultaneously. The test rifle was my 6mm BR Ackley (BRA) F-class rig with fire-formed brass and 200 rounds on the new barrel.
Chronogaphs Tested
LabRadar
MagnetoSpeed V3
Oehler Model 35P
Temperature: 86 deg. F
Elevation: 854 feet
Cartridge: 6mm BRA (105gr Berger VLD)
Time between shots: 45 seconds
To start off, five rounds were fired to make sure all systems were recording and to warm the barrel. Then the test was 20 shots fired across all three instruments with 45 seconds between shots. The Oehler was set 7.5 yards from the muzzle so 12 FPS was added to the recorded value.
We were using the internal trigger on the LabRadar. The manual says the Vo indicated is the actual muzzle velocity when using the internal trigger, but not if using the Doppler. The 12 FPS Oehler adjustment (back to MV) was based on the Berger Ballistics Calculator.
Results of the Triple Chronograph Shoot-Out:
LR-M is FPS variance between LabRadar and MagnetoSpeed V3. LR-O is FPS variance between LabRadar and distance-adjusted Oehler 35P. You can see all three chronos were very consistent. SD was identical with the LabRadar and MagnetoSpeed.CLICK HERE for spreadsheet.
The tester, Randy S. (aka AAA) says: “Judge for yourself, but I was impressed by all.”
Comments by Forum Members
Our Forum members expressed interest in this Triple Chronograph test. Some confirmed that the LabRadar and Magnetospeed give very similar FPS numbers, based on their own tests:
“Great test and thanks for sharing. I’ve tested my MagnetoSpeed and LabRadar together and results are always within 2-4 FPS of one another.” — Big D
“Very happy to see your numbers support my decision to buy a MagnetoSpeed. Had read reports comparing it to the Oehler and the numbers I get seem to be supported by my long range shooting results. Many thanks for taking the time and effort [to perform] this comparative test. Always good to get actual test results.” — Texas10
“I did a 4-shot test with my MagnetoSpeed and another shooter’s LabRadar a couple of days ago. The results were within 4 fps with the LabRadar being optimistic.” — Pat Miles
Forum Member Powderbreak studied AAA’s original spreadsheet from the chronograph trio test, then figured out the shot-by-shot FPS variance between the machines. He concluded that all the machines performed very well. Powderbreak posted:
Analyzing the Triple Chronograph Test — What Can We Conclude?
AAA did a great job of comparing the 3 chronos. What conclusions can be drawn?
1) I have not checked the manufacturer’s claims of accuracy, but the three chronos are very close to one another. There is no way for us to determine the actual true velocities, but we do not need to do so. Any of the chronos would be more than adequate for an accurate shooter.
2) The resolution of the three chronographs is actually pretty astounding. One foot per second (FPS) is a resolution of 0.033%.
3) AAA did a great job of reloading a very consistent round. With an extreme spread of 33 fps out of 3014 for 20 rounds, that is only 1.09% total spread of velocities.
4) There is a closer velocity match between the MagnetoSpeed and the LabRadar, but that does not mean the Oehler is less accurate. There is simply an offset between the Oehler and the other two. This could be due to the greater distance, the location, or the internal working of the Oehler.
5) Believe your chronograph, it is probably the most accurate reloading tool that you own.
Brian Litz of Applied Ballistics carefully explained the operation, set-up, accuracy and comparison of AB’s chronographs in his books. [Those books] are well worth the money, and give great insight into the workings of chronographs.” — Powderbreak
In the PRS game, the 6.5 Creedmoor has ruled the roost. However more and more serious competitors are moving to the 6mm Creedmoor cartridge because it offers lower recoil and a flatter trajectory (with some bullets). If you are a fan of the 6mm Creedmoor — take heart. Lapua has started production of 6mm Creedmoor cartridge brass, which should hit American shores later in the year. Yes this 6mm Creedmoor brass has small primer pocket and small flash hole — allowing it to stand up to repeated loading cycles with stout pressures.
Here is the official announcement…
Lapua 6mm Creedmoor Cartridge Brass
Lapua is pleased to announce the new 6mm Creedmoor case, a necked down version of the extremely popular 6.5mm Creedmoor designed to produce higher velocities, flatter trajectories, and reduced recoil.
Customer demand for a 6mm version followed almost immediately after the release of the original Creedmoor case. Aside from the neck dimensions, our new 6mm Creedmoor cases shares the same features and characteristics that make Lapua the standard for 6.5 Creedmoor brass. It is a beautifully-drawn case, properly annealed at the neck and shoulder, with head metallurgy specifically chosen for durability, and the same small rifle primer, small flash-hole design that delivers the ultimate accuracy edge. The smaller 6mm bore diameter offers an excellent selection of proven low-drag match bullets that offer outstanding long range performance with even less recoil.
While the original 6.5 Creedmoor was designed with NRA High Power competition in mind, other disciplines, including the Precision Rifle Series (PRS), were quick to see the positive attributes of this cartridge. We know Lapua’s latest offering will find a niche with discerning shooters in demanding competitive disciplines.
We expect Lapua’s new 6mm Creedmoor cartridge brass to be favored by High Power shooters and serious varminters as well as tactical competitors. The Lapua 6mm Creedmoor cases will be available in the USA later in 2018.
The new Lapua 6mm Creedmoor Brass will definitely be a hit with PRS Competitors…

Here’s a great gift for Father’s Day that any dad with a truck should appreciate. Forum member John Niemi crafts custom hitch covers that look like the end of a cartridge case, complete with head-stamp. Costing $75.00 (delivered), they are made out of solid brass with a stainless steel “primer”. The diameter of the brass is 4 inches and the engraved letters are about half an inch tall. The section that slides over the trailer hitch is aluminum, so you don’t have to worry about rust.
The “headstamp” can include your favorite cartridge-maker and caliber (wildcats too!), or you can include the name of your business. John tells us: “I can engrave any text on one as long as there is enough room for it. Turn around time is usually less then a week after payment. I have sold many of these and everyone has been extremely happy with the quality and workmanship that I put into my product. These make great one-of-a-kind gifts.”
$75.00 Delivered in the USA
The current price for brass bullet hitch covers from John Niemi is $75.00 shipped anywhere in the USA. To order, send email to JohnNiemi [at] charter.net or call (503) 440-1954. John said he should be able to offer pretty quick turn-around, unless he just gets swamped this week.

Displayed are results with Federal Gold Medal Match — quite impressive accuracy!
Criterion Barrels has published an interesting Ammo Comparison Test, shooting seven (7) different varieties of .223 Rem ammunition out of an AR15 fitted with Criterion Barrel. Each ammo type was chronographed (10-shot string), then five-shot groups were shot at 100 yards. Along with handloads (69gr Sierra MK + Varget), six (6) types of commercial ammo were tested:
PREMIUM Type Ammo:
Federal Gold Medal Match (69gr SMK)
Creedmoor 75gr HPBT
Prime 77gr OTM (Open Tip Match)
BULK Type Ammo:
Federal American Eagle XM193 (55gr FMJ)
Wolf Gold (55gr FMJ)
Wolf Polyformance Steel Case (55gr FMJ)
Here are the results for the four best commercial ammo types tested: Federal Gold Medal Match (GMM) with 69gr SMK, Prime 77gr OTM, Creedmoor 75gr HPBT, and American Eagle XM193 (55gr FMJ). The Gold Medal Match shot the best of all factory ammo tested. In fact, the GMM even shot slightly better than the handloads, which averaged 0.79″ for the three accurized groups.
The results are quite interesting. The Federal GMM actually shot the best, beating “untailored” handloads. Basic accurizing efforts and a much better rest set-up showed significant benefits with most ammo types (but not the bulk Wolf Ammo). As you would expect, the more expensive ammo shot best: “Chart 1.2 [below] showcases the average [after accurizing] five-round group sizes with each type of ammunition at 100 yards, while Chart 1.3 lists the price per round of each ammunition type. It becomes immediately evident by reviewing these two graphs that there is an inverse relationship between group size and factory ammunition price.”
Accurizing Improvements — Better Scope, Better Rests, Accu-Wedge
As you would expect, some basic accurizing efforts improved accuracy with the better ammo. The accurizing process included: 1) Swapping to a Vortex Viper PST Gen 1 6-24x50mm optic; 2) Adding an Accu-Wedge; 3) Improving fitment during reassembly, and 4) Switching from Harris bipod to a Sinclair Front Rest and Edgewood rear bag for added stability. The same 1:8″-twist Criterion barrel was used throughout the testing process.
If you shoot an AR15, or even shoot a .223 Rem bolt gun with factory ammo, you should probably read this test in full. Criterion put a lot of time into the testing, and experimented with a variety of AR options showcased in a series of YouTube videos. SEE: Accurizing the AR-15 Video Playlist.
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, optics, 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. Natchez — Bushnell 6-18x50mm Trophy, $79.99 after Rebate
Looking for a decent medium-power zoom optic for a varmint rifle or rimfire rig? Here’s a great deal on a name-brand scope with side-focus parallax and good warranty. This 6-18x50mm Bushnell Trophy certainly won’t compete with an elite scope, but at $129.99 it’s hard to go wrong. A verified buyer reports: “Likely a best buy/solid value purchase. Glass is good, probably best in this price range. Used for targets — [it was] clear, and focuses down to about 10 yards.” The reticle is Bushnell’s Multi-X — the lines are fairly thick, but it will work for general varmint and target duties. NOTE: This Trophy Scope also qualifies for a Bushnell $50 Trophy Bucks Rebate (good through June 30, 2018). That $50 Rebate lowers your net cost to just $79.99!
2. CDNN — Colt Competition AR15 Kit, $599.99
The Colt Kit does NOT include barrel, bolt carrier group, charging handle, or magazine.
This affordable Colt AR15 Kit includes upper, complete lower, handguard, and Magpul stock. To this, add your choice of barrel and optic. We like this option because the barrel is so important to accuracy and overall performance. This Colt package costs $599.99. Add a match-grade, finish-chambered barrel from Criterion or Krieger, plus bolt carrier group, and you’re in business. The Magpul PRS stock features a quick-adjustable cheek-piece and butt-plate — allowing you to easily adapt head position and LOP for your discipline of the day. The straight-toe PRS stock works great in a rear bag. This is a good platform for a PRS Gas Gun Division rifle.
3. Amazon — RCBS ChargeMaster Lite, $186.99
Need a good, modern electronic scale/dispenser? The modern ChargeMaster Lite offers good performance for the price — now $186.99 at Amazon and $187.49 Brownells. But at Brownells, with Code NCS you can get $15 off and free shipping — lowering your net cost to $172.49! That’s a killer deal — other retailers are charging up to $260.00 for this machine. Once calibrated, we found the ChargeMaster Lite’s dispensing to be very accurate. RCBS claims +/-0.1 grain. This newer machine is a bit easier to program than the original ChargeMaster. Verified purchasers have been happy, but with one complaint: “You cannot turn off the beeping. The [original ChargeMaster] has a way to mute the beeping. This one does not.” Take note.

That’s notable because you almost never see this discounted below the $559.95 MAP price. You can save $50.00 on this unit now through June 24, 2018. This is a factory-authorized, once-a-year Summer Sale. The sale extends through 6/24/2018. You can get the LabRadar from top vendors including Creedmoor Sports, Bruno Shooters Supply, and Midsouth Shooters Supply.
Get a Ruger Precision Rifle in 6mm Creedmoor for $899.99 complete. That price, which includes rings, is great for a Gen 2 model. If you’ve been thinking of purchasing a Ruger Precision Rifle (RPR) chambered for the 6mm Creedmoor cartridge, this is a killer deal. Right now CDNN Sports is offering this popular tactical rig for under $900.00, in the 6mm Creedmoor chambering. This shoots faster and flatter than the 6.5 Creedmoor — so many PRS guys have switched to it. This is a good choice for the PRS production class, or you can take in to another level of performance with a Pre-Fit 26″ cut-rifled barrel from Krieger. This is the lastest RPR Gen 2 version with the upgraded handguards. Heck of a bargain boys — you can pay $1200 or more elsewhere for the same rifle.
6. EuroOptics — Leica CRF 2000, $399.00
This may be the best deal we’ve seen on the vaunted Leica 2000-B Laser Rangefinder (LRF) with 7-power optic. This unit is rated out to 2000 yards on reflective objects (in real-world use it will laze a deer well past 800 if you can hold steady). The Leica 2000-B features air pressure and temperature sensors, plus on-board inclinometer. Angle correction works out to 1200 horizontal yards equivalent, with the true hold-over displayed in both MILs and MOA. The compact Leica CRF 2000-B weighs just 6.5 ounces and measures 4.5″ L x 2.25″ H x 1.25″ W. It has a waterproof outer shell.
7. Champions Choice — Deluxe 58″-Long Rifle Case, $68.00
Many of our readers shoot Palma, F-Class, and ELR rifles with long barrels (up to 35″). It’s difficult to find high-quality, well-padded cases that fit very long rifles. Champion’s Choice offers just such a product, the 58″ Deluxe Soft Rifle Case. With thick 1″ padding on each side, big pockets, and backpack straps, this black/blue/white gun case has earned rave reviews from our Forum members. There’s plenty of room for big scopes, and it even comes with an internal tube to hold your cleaning rod.
8. Amazon — MTM AC4C Ammo Crate with 4 Ammo Boxes, $24.99
Here’s a very cool product from MTM at a great price. The versatile MTM AC4C Ammo Carrier features four, lockable polymer ammo cans in a fitted, four-slot 23.5” x 11.3” x 7.5” carry crate. This makes it easy to haul four full ammo cans. Actual purchasers have raved: “Moments after I received this storage box set I ordered another. Very well built and great design. Awesome and a steal at the price.” Right now this is on sale at Amazon for just $24.99 with free prime shipping. The system includes four lockable, O-Ring 11.3″ x 7.2″ x 5″ ammo cans (AC30T) for multi-caliber ammo storage. The crate even includes tie-down points for transport in a cart or ATV. NOTE: Earlier this summer this MTM AC4C system sold for $39.99. The current $29.99 price represents a 25% savings!
9. Amazon — Howard Leight MAX NRR33 Earplugs, $8.22/50 Pairs
20 Pairs
50 Pairs
These Howard Leight NRR33 Max plugs are your Editor’s favorite foam earplugs. Between shooting, motorcycling and mowing lawns, I probably have Max plugs in my ears 2-3 days a week. This is a very good price for a bulk pack of 50 pairs. And if you act soon, you can get free shipping to boot.
Summer’s here, so many folks will head to the hinterlands on prairie dog safaris. On a good P-Dog adventure, you may shoot hundreds of rounds over a long weekend. So you’ll need plenty of ammo. With these ammo volume requirements, you probably won’t have time to load to benchrest standards, and you may not have the budget for match-grade bullets. To save time you may throw (rather than weigh) your charges, or even load on a progressive press. This all raises the question of ammo accuracy — how good is “good enough”? A Sierra Bullets expert answers that question here — explaining how to efficiently load ammo for varmint work.
Ammunition Accuracy Requirements 101 — Varmint Ammo
This story based on article by Sierra Bullets Chief Ballistician Tommy Todd
I load and shoot ammunition for a living. In my duties here at Sierra I constantly test bullet accuracy for our production needs. Because of this, I shoot a variety of different calibers and cartridges on a daily basis and a large demand of this shooting is keeping the guns and loads tuned for optimum accuracy. I have a very narrow window of tolerances to maintain in order to provide our customers (you) with the most accurate bullets on the market.
I have learned many tricks and techniques over the years to tuning a load, prepping brass, and cleaning barrels to keep a gun shooting. I often utilize the things I have learned and take them to extreme levels when competing in a shooting event. I also often ignore most of these things (other than safety) and simplify the process if the shooting I will be doing does not warrant.
Recently I went on a prairie dog shoot in Wyoming with some good friends. The targets cooperated as did the weather with the exception of some challenging winds we experienced. We had a great time and make a lot of hits on those small rodents. When loading for the 223 Remington rifles and the TC Contender, I cut a few corners in the ammunition-loading process due to both time constraints and accuracy needed. When shooting at a prairie dog a miss is simply that, but when shooting at say the X-ring at 1000-yard competition, a poorly-placed shot [harms your] placing in the match. Because of this, I can afford to miss an occasional shot at a varmint due to ammunition capability without worry but will not allow the same tolerances in my match ammo. For the Wyoming trip I utilized a powder measure and simply dumped the charges into primed cases that had been full-length sized and primed.
I had measured enough for length to know that while there was some variance all were under maximum length. I know there is some variation of the measure I utilized but not significant enough to warrant weighing every charge. When seating the bullets a competition seating die was used and I verified OAL on the occasional cartridge to make sure nothing changed.
The ammo produced shot under one inch at 200 yards in one of the guns I planned on taking on to Wyoming with me. [Editor: That was for TEN Shots — see below.] I knew I had loaded ammunition that was quite suitable for the task at hand which was evidenced by the number of hits I was able to make at fairly long range.
NOTE: The author, Tommy Todd, explains that, when loading ammo for F-Class matches, he uses more exacting methods. He weighs every charge and seats his bullets carefully with an arbor press. Todd adapts his methodology for his particular application. The lesson here is to load to the level of precision demanded by your discipline. READ Full Story HERE.
Sinclair International has created a series of helpful articles on rifle cartridge reloading. Today’s feature lists ten basic steps for precision hand-loading, with links to longer, detailed Sinclair Int’l technical articles providing more complete information. There’s a lot of helpful info here guys, if you click all the links to access the ten “long form” articles.
Tying It All Together: 10 Steps To Precision Handloads
Feature based on article by Roy Hill, Brownells/Sinclair Copywriter
Sinclair International offers a series of detailed articles on hand-loading precision rifle ammunition. The articles are included in Sinclair’s GunTech Articles Archive, but sorting through the index to find each article takes time. To help you access all these articles quickly, here’s a handy summary of ten key topics, with links to longer articles covering each subject in detail.
Part 1: The first step in making high-quality handloads is to carefully choose the best brass for your application. You need to know how to identify the different types of brass and how to choose the best kind for the ammo you want to load. CLICK HERE for Part 1.
Part 2: Even high-quality brass can have burrs around the flash hole that can interfere with the primer flame and cause inconsistent ignition – which can lead to shot groups opening up. Flash hole deburring is a critical step in making sure primers ignite powder consistently. CLICK HERE for Part 2.
Part 3: The next step is to make sure the primer pockets are square and uniform. Like flash hole deburring, primer pocket uniforming may reduce variations in primer ignition by ensuring more consistent primer seating. CLICK HERE for Part 3.
Part 4: Making sure all your cases are precisely the same length is crucial, especially when you use cases that have been fired before. Case trimming is the way to get there. CLICK HERE for Part 4.
Part 5: After trimming, cases still have to be resized. In order for them to work through the resizing die, they have to be lubricated. The case lube method you choose is crucial to making precision handloads. CLICK HERE for Part 5.
Part 6: Now it’s time to choose the dies that will resize your cases. There are several important options to consider in selecting the right sizing dies. CLICK HERE for Part 6.
Part 7: Wait! You’re not quite ready to start sizing yet. There’s yet more to consider before you start cranking cases through the press. Learn more about setting up and adjusting your sizing dies. CLICK HERE for Part 7.
Part 8: Once the cases are completely prepped, it’s time to start putting fresh components back into them. We start off by seating primers. CLICK HERE for Part 8.
Part 9: After the primers are seated, it’s time to drop in the powder. There are several tools that will help you handle powder for precision handloads. CLICK HERE for Part 9.
Part 10: The final step in the process is carefully seating the bullet to just the right depth. And then… you’re ready to try your loads at the range. CLICK HERE for Part 10.

2. CDNN — Winchester XR Rifle $289.99 with $50 Rebate
We like the Winchester XPR as an affordable, entry-level hunting rifle. The three-lug bolt has a short throw, the mags seat easily and the rifle balances well. CDNN is offering the XPR for just $339.99. That’s a great price, but it gets even better. Winchester is offering a $50.00 factory rebate, lowering your net cost to just $289.99. That’s less than you’ll pay for a new custom barrel! This CDNN deal is available now for five popular chamberings: .243 Win, .270 Win, 7mm08, .308 Win, and .30-06. Winchester’s $50 Factory Rebate applies to any new Winchester XPR rifle purchased from May 25 through July 15, 2018. For more info, visit rebates.winchesterguns.com.
3. Cabela’s Armor Xtreme Plus Single Long-Gun Case — $119.00
Many match rifles have barrels 28″-30″ long, and a brake/tuner can add even more length. It can be difficult to find a hardshell case that is long enough but also affordable and not too bulky. Cabela’s has a rifle case that fits the bill — the new Armor Xtreme Plus Single Long-Gun Case. This measures a full 52″ long INSIDE. Waterproof, dustproof, and O-ring sealed, this case meets airline requirements, with a pressure-release valve to equalize pressure during air travel. This case, which has a Lifetime Warranty, was recommended by a Forum member: “I own several Cabela’s Armor Extreme long gun cases — very solid and I really like them. The double case is really heavy and bulky for just a routine range trip with one rifle. The older single model is 48” x 8.5” on the inside. Cabela’s changed the single rifle design to make it longer and wider — it is now 52″ x 11.5″ inside – just right for me.” This Cabela’s case weighs 13.5 pounds, and external dimensions are: 53.5″ L x 14″ W x 5″ H.
4. MidwayUSA — Vortex 6-24x50mm HS LR for $399.00
The Vortex Viper HS features side-focus parallax, low-dispersion glass, and a BDC Reticle (shown at right) that has hold-over marks. That can be useful in the varmint fields. (Do your own testing to find the distance settings of the hold-overs with your cartridge and velocity.) The Viper has a 30mm main tube and weighs 21.4 ounces without rings. Max elevation and windage travel are both 42 MOA — plenty for typical varmint applications. At 6X power, the 100-yard Field of View is 17.8 feet.
This Viper HS scope comes with the full Vortex VIP lifetime warranty. MidwayUSA’s $399.99 price is a very good deal. The manufacturer’s suggested retail price (MSRP) is $699.00.
CLICK HERE for video of 6-24x50mm Vortex Viper HS LR model. This is NOT the same as the basic Viper HS, but it shares many features.
A strong argument can be made that the best home defense firearm is a 12 gauge shotgun. This Mossberg 500 is a reliable 12ga pump-gun with useful upgrades including ghost-ring sights and barrel heat-shield. This Model 500 Tactical boasts an 8-shell capacity and weighs 7 pounds unloaded. Order now from GunBuyer.com for $309.00.

Right now, Brownells is running a big sale on Howa Barreled Actions, in a wide variety of chamberings. You may want to pick up one of these barreled actions, which start at $259.99.

8. Amazon — Jialitte Scope Bubble Level, $11.99
If you shoot long range, you need a scope level. This nicely designed Jialitte Scope Bubble Level is fully CNC-machined to close tolerances for a good fit. It features a 30mm milled inside diameter, plus an inner insert ring so it will also fit 1″-diameter main tubes — that dual-diameter versatility is a nice feature. We also like the way the unit is nicely radiused, and has a low profile in the middle. User reviews have been very positive. You could easily pay $35.00 or more for a 30mm scope level. Purchasers have praised this product — almost all verified buyers have rated this five stars.
9. Midsouth — Hornady 17 HMR Ten Boxes for $84.99
Varmint hunters take note. Here’s a great deal on premium 17 HMR ammo. Midsouth is selling 500 rounds of Hornady 17 HMR ammo for $84.99. That works out to just $8.50 per 50-rd box — the best price we’ve seen in a while. Loaded with 17gr V-Max bullets, this ammo is accurate — expect about 1 MOA at 100 yards in a good rifle. The V-Max bullets are effective on small varmints out to 200 yards.
10. Amazon — First Aid Kit, $16.99
Every hunter or shooting sports enthusiast should have a first aid kit available during hunts and trips to the range. This handy Preparify First Aid Kit is 7.9″ x 6″ x 3.1″, so it’s small enough to stow in a backpack, range-bag, or glove-box. It contains 35 products (100 pieces) including: scissors, lancets, tweezers, tourniquet, CPR mask, emergency blanket, splints, safety pins, cold pack, cleaning wipes, sterile pads, bandages, whistle, first aid booklet (and more). Everything is visible in clear pockets, with space to add a few extra items. A best-selling product on Amazon, this compact first-aid kit is a good value at $16.99.
Customer demand for a 6mm version followed almost immediately after the release of the original Creedmoor case. Aside from the neck dimensions, our new 6mm Creedmoor cases shares the same features and characteristics that make Lapua the standard for 6.5 Creedmoor brass. It is a beautifully-drawn case, properly annealed at the neck and shoulder, with head metallurgy specifically chosen for durability, and the same small rifle primer, small flash-hole design that delivers the ultimate accuracy edge. The smaller 6mm bore diameter offers an excellent selection of proven low-drag match bullets that offer outstanding long range performance with even less recoil.
The “headstamp” can include your favorite cartridge-maker and caliber (wildcats too!), or you can include the name of your business. John tells us: “I can engrave any text on one as long as there is enough room for it. Turn around time is usually less then a week after payment. I have sold many of these and everyone has been extremely happy with the quality and workmanship that I put into my product. These make great one-of-a-kind gifts.”
The Vortex Viper HS features side-focus parallax, low-dispersion glass, and a BDC Reticle (shown at right) that has hold-over marks. That can be useful in the varmint fields. (Do your own testing to find the distance settings of the hold-overs with your cartridge and velocity.) The Viper has a 30mm main tube and weighs 21.4 ounces without rings. Max elevation and windage travel are both 42 MOA — plenty for typical varmint applications. At 6X power, the 100-yard Field of View is 17.8 feet.
