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. Amazon — Sightron 10-50x60mm SIII, as Low as $939.00
Need a high-magnification scope for long-range competition? Among quality scopes with 40+ power, we think the Sightron SIII 10-50x60mm scope is the best value on the market. These scopes are available through Amazon.com for under $940.00. That’s about half the price of a Leupold 7-42x56mm VX-6, and 40% of the cost of a Nightforce 15-55X competition model. The Sightron is a good product with a lifetime manufacturer’s warranty. And it works — at the 2017 IBS 600-yard Nationals, 4 of the Top 10 shooters (including the 2nd-place finisher) used Sightron 10-50X scopes. Though reasonably priced, this 10-50x60mm optic is definitely good enough to win long-range benchrest and F-Class matches.

6. Amazon — Sig Kilo 1250 Laser Rangefinder, $222.21
Every outdoorsman can use a good laser rangefinder. If you don’t have a quality, compact Laser Rangefinder, here’s a great deal. The 6x20mm SIG Kilo 1250 Camo Rangefinder is now on sale for $222.21 with free shipping. This is a very accurate LRF, that ranges deer-sized targets at long distances quickly. The scan mode is very fast (4X per second) and this offers both line of sight (LOS) or angle modified range (AMR). The unit is compact and light — a bonus for hunters. There are more expensive Laser Rangefinder that can range farther, but this $222 Kilo 1250 will definitely do the job on a hunting trip for one-third the price.
7. Midsouth — 10% Off All Sierra Bullets
We’ve been impressed with recent offerings from Sierra Bullets. Many popular Sierra MatchKing bullet types now come “Pointed” from the factory. That pointing process uniforms the bullet tips, maintaining a more consistent Ballistic Coefficient (BC) among all the MatchKings in a box. That, in turn, can produce less vertical dispersion, because the bullet-to-bullet aerodynamic drag variance is signficantly reduced. We also like Sierra’s Varmint and Hunting bullets. Choose traditional bullets or tipped bullets — Sierra offers both types. Right now Midsouth is offering 10% off all Sierra rifle and pistol bullets in stock. Considering that Midsouth’s bullet prices were very competitive to begin with, this is a good deal.
8. CDNN Sports — HK 416 .22LR Rimfire Rifle, $389.88
If you are looking for an AR-type .22 LR rifle for cross-training and rimfire tactical matches, the HK 416 is a fine choice. Made by Walther under license, these HK 416 D145RS rimfire rifles are accurate and reliable. This is a good deal at $389.88. The HK 416 normally sells for $550.00 to $600.00. One purchaser writes: “Great .22. I have had this gun a couple of months and have put about 500 rounds of 5 different brands of ammo through it. Not one FTE. I have shot other brands that can’t get through one 30-round mag without a failure.” CLICK HERE for Product Details.
9. Grafs.com — Magnetospeed Sporter $178.99
If you have been waiting to get a Magnetospeed… wait no longer. Priced at just $178.99 at Grafs.com, the Magnetospeed Sporter model costs less than half as much as Magnetospeed’s V3 models. This chronograph attaches directly to your barrel so you don’t have to go downrange to position tripods and set up skyscreens. For most people the Sporter Model contains all the features they need. Using Magnetospeed’s XFR adapter (sold separately), data can be transferred easily from the display module to your mobile device. This is also available from Amazon for $179.00 with free shipping. READ Magnetospeed Sporter Review.
We like reactive targets. It’s fun to “ring steel” and see a target move instantly when hit. For just twenty bucks (including shipping), it’s hard to go wrong with this 8″ AR500 Steel Gong. The 8″-diameter size is big enough for zeroing at 200 yards, yet offers a nice challenge at 500 yards and beyond. There is also a 6″-diameter model for just $14.00.
Here’a useful article by Sierra Bullets Media Relations Manager Carroll Pilant. This story, which originally appeared in the Sierra Blog, covers some of the more common ammo problems that afflict hand-loaders. Some of those issues are: excessive OAL, high primers, and improperly sized cases. Here Mr. Pilant explains how to avoid these common problems that lead to “headaches at the range.
I had some gentlemen at my house last fall getting rifle zeros for an upcoming elk hunt. One was using one of the .300 short mags and every 3rd or 4th round would not chamber. Examination of the case showed a bulge right at the body/shoulder junction. These were new cases he had loaded for this trip. The seating die had been screwed down until it just touched the shoulder and then backed up just slightly. Some of the cases were apparently slightly longer from the base to the datum line and the shoulder was hitting inside the seating die and putting the bulge on the shoulder. I got to thinking about all the gun malfunctions that I see each week at matches and the biggest percentage stem from improper handloading techniques.
One: Utilize a Chamber Gage
Since I shoot a lot of 3-gun matches, I see a lot of AR problems which result in the shooter banging the butt stock on the ground or nearest solid object while pulling on the charging handle at the same time. I like my rifles too well to treat them that way (I cringe every time I see someone doing that). When I ask them if they ran the ammo through a chamber gage, I usually get the answer, “No, but I need to get one” or “I didn’t have time to do it” or other excuses. The few minutes it takes to check your ammo can mean the difference between a nightmare and a smooth running firearm.
A Chamber Gauge Quickly Reveals Long or Short Cases
Size Your Cases Properly
Another problem is caused sizing the case itself. If you will lube the inside of the neck, the expander ball will come out a lot easier. If you hear a squeak as the expander ball comes out of a case neck, that expander ball is trying to pull the case neck/shoulder up (sometimes several thousandths). That is enough that if you don’t put a bulge on the shoulder when seating the bullet, like we talked about above, it can still jam into the chamber like a big cork. If the rifle is set up correctly, the gun will not go into battery and won’t fire but the round is jammed into the chamber where it won’t extract and they are back to banging it on the ground again (with a loaded round stuck in the chamber). A chamber gage would have caught this also.
Oversizing cases also causes problems because the firing pin doesn’t have the length to reach the primer solid enough to ignite it 100% of the time. When you have one that is oversized, you usually have a bunch, since you usually do several cases at a time on that die setting. If the die isn’t readjusted, the problem will continue on the next batch of cases also. They will either not fire at all or you will have a lot of misfires. In a bolt action, a lot of time the extractor will hold the case against the face of the breech enough that it will fire. The case gets driven forward and the thinner part of the brass expands, holding to the chamber wall and the thicker part of the case doesn’t expand as much and stretches back to the bolt face. If it doesn’t separate that time, it will the next time. When it does separate, it leaves the front portion of the case in the chamber and pulls the case head off. Then when it tries to chamber the next round, you have a nasty jam. Quite often range brass is the culprit of this because you never know how many times it has been fired/sized and in what firearm.’Back to beating it on the ground again till you figure out that you have to get the forward part of the case out.
Just a quick tip — To extract the partial case, an oversized brush on a cleaning rod [inserted] and then pulled backward will often remove the case. The bristles when pushed forward and then pulled back act like barbs inside the case. If you have a bunch of oversized case that have been fired, I would dispose of them to keep from having future problems. There are a few tricks you can use to salvage them if they haven’t been fired though. Once again, a case gage would have helped.
Two: Double Check Your Primers
Another thing I see fairly often is a high primer, backwards primer, or no primer at all. The high primers are bad because you can have either a slam fire or a misfire from the firing pin seating the primer but using up its energy doing so. So, as a precaution to make sure my rifle ammo will work 100% of the time, I check it in a case gage, then put it in an ammo box with the primer up and when the box is full, I run my finger across all the primers to make sure they are all seated to the correct depth and you can visually check to make sure none are in backwards or missing.
Three: Check Your Overall Cartridge Length
Trying to load the ammo as long as possible can cause problems also. Be sure to leave yourself enough clearance between the tip of the bullet and the front of the magazine where the rounds will feed up 100%. Several times over the years, I have heard of hunters getting their rifle ready for a hunt. When they would go to the range to sight in, they loaded each round single shot without putting any ammo in the magazine. On getting to elk or deer camp, they find out the ammo is to long to fit in the magazine. At least they have a single shot, it could be worse. I have had hunters that their buddies loaded the ammo for them and then met them in hunting camp only to find out the ammo wouldn’t chamber from either the bullet seated to long or the case sized improperly, then they just have a club.
Four: Confirm All Cases Contain Powder
No powder in the case doesn’t seem to happen as much in rifle cartridges as in handgun cartridges. This is probably due to more handgun ammo being loaded on progressive presses and usually in larger quantities. There are probably more rifle cartridges that don’t have powder in them than you realize though. Since the pistol case is so much smaller internal capacity, when you try to fire it without powder, it usually dislodges the bullet just enough to stick in the barrel. On a rifle, you have more internal capacity and usually a better grip on the bullet, since it is smaller diameter and longer bearing surface. Like on a .223, often a case without powder won’t dislodge the bullet out of the case and just gets ejected from the rifle, thinking it was a bad primer or some little quirk. For rifle cases loaded on a single stage press, I put them in a reloading block and always dump my powder in a certain order. Then I do a visual inspection and any case that the powder doesn’t look the same level as the rest, I pull it and the one I charged before and the one I charged after it. I inspect the one case to see if there is anything visual inside. Then I recharge all 3 cases. That way if a case had powder hang up and dump in the next case, you have corrected the problem.
On progressive presses, I try to use a powder that fills the case up to about the base of the bullet. That way you can usually see the powder as the shell rotates and if you might have dumped a partial or double charge, you will notice as you start to seat the bullet if not before. On a progressive, if I don’t load a cartridge in one smooth stroke (say a bullet tipped over sideways and I raised the ram slightly to reset it) Some presses actually back the charge back adding more powder if it has already dumped some so you have a full charge plus a partial charge. When I don’t complete the procedure with one stroke, I pull the case that just had powder dumped into it and check the powder charge or just dump the powder back into the measure and run the case thru later.
I could go on and on but hopefully this will help some of you that are having these problems cure them. A case gage really can do wonders. Stay tuned for Easy Easy Ways to Save Yourself Headaches at the Range Part 2!
NOTE: There are ten (10) shots in the group, but for simplicity we are only displaying five (5) shot circles. Adding more circles won’t change the measurement because the two most distant shots, which determine group size, ARE included.
What kind of 200-yard accuracy can you get in an enclosed, underground test range? Would you believe 0.162 MOA at 200 yards with a .338? Have a look at these test targets from Sierra Bullets. Like most bullet manufacturers, Sierra does live-fire bullet testing to ensure that Sierra projectiles perform as promised, with repeatable accuracy. Sierra tests bullets in its own underground test complex. Sierra’s 300-meter test range is the longest, privately-owned underground bullet test facility in the world. Sierra offers free tours of the test tunnel as part of Sierra’s Factory Tour Program.
Day in and day out, various bullet types are tested using a big collection of barreled actions. These barreled actions are clamped in stout, return-to-battery test fixtures. These big, heavy test fixtures provide near-perfect repeatability (with no human-induced holding or aiming errors).
Sierra Bullets 10-Shot Groups at 200 yards
Check out these 10-shot test groups shot at the Sierra Test Range at 200 yards. Note that the numbers listed on each sample are actual measurements in inches. To convert to MOA, cut those numbers in half (to be more precise, divide by 2.094, which is 1 MOA at 200 yards). For example, the 0.340″ middle group works out to 0.162 MOA at 200 yards.
Scan-Verified 0.162 MOA Accuracy at 200 Yards
To verify the accuracy of Sierra’s measurements, we measured the middle (.338 caliber) 10-shot group with our On-Target Group Measurement software. We registered a group size reading of 0.339″ — within one-thousandth of the Sierra measurement. The calculated group size in MOA (Minute of Angle) is 0.162.
That’s amazingly good for ten rounds of big .338 caliber bullets. A FIVE-shot 0.162 MOA group at 200 would be considered excellent at any benchrest match. But remember this target has TEN shots. The current, one-target IBS world record for ten shots at 200 yards is 0.245″, set by Ed Watson in 1999.
Bevy of Barreled Actions for Bullet Testing
Sierra Bullets uses dozens of barreled actions for testing bullets in its enclosed, 200-yard test range. Each barrel has its own logbook to track the barrel’s usage.
Hodgdon has just introduced a versatile new Winchester-brand pistol powder with a clean formulation. WinClean 244 is a modern, Winchester-branded propellant “ideally suited to .38 Special, .45 Auto, and 9mm standard loads.” That means WinClean 244 is designed for moderate pressure target loads. That’s good news for hand-loaders who enjoy target shooting with these popular cartridges.
Hodgdon, which markets Winchester powders, says that new WinClean 244 is consistent, and clean burning with a low flash: “The WinClean formulation reduces copper fouling and residue, extending accuracy for longer shooting periods.” It will be interesting to see if this is noticeably cleaner-burning than other popular powders. In pistol barrels we are actually less concerned with copper fouling than with general “sootiness” and carbon.
With its clean-burning qualities, “shooters are really going to like loading handgun cartridges with this powder” said Tim Vaitekunas, vice president of product development at Hodgdon. WinClean 244 powder, in 1-, 4- and 8-pound canisters, should be in stores in January 2018. Load Data is now available right now on the Hodgdon Reloading Data Center.
This Editor used to compete in Action Pistol matches, so I’ve loaded thousands of rounds of pistol ammunition using a wide variety of pistol propellants. I tend to favor Vihtavuori N310/N320 for .45 ACP, and Alliant powders for 9mm Luger, but it will be interesting to see how WinClean 244 works for these chamberings. Many powders work well for .38 Special loads, but new 244’s low flash could be an advantage there too.
Pistol Showcase — Candidates for WinClean 244
The Sig P210 SuperTarget is a modern 9mm Luger pistol with exceptional accuracy and one of the best out-of-the-box triggers you’ll ever try. Winchester WinClean 244 is suitable for a variety of bullet weights in the 9x19mm (9mm Luger) cartridge.
The 8-shot Smith & Wesson Model 627 Pro is an exceptional revolver that balances well and can shoot 1″ groups at 25 yards with tuned handloads. On this particular Model 627, featured on YouTube, the owner added a Hogue Pau Ferro wood grip, Hogue Extended Cylinder Release, and Wilson Combat trigger spring kit. In this kind of wheelgun, you can shoot moderate .38 Special target rounds loaded with new WinClean 244 powder.
Do you shoot a .45 ACP? We love this short, fat cartridge because it is inherently accurate, it makes big, easy-to-see holes in paper, and because it it works so well in the classic 1911 series of pistols. It is hard to beat a good, tuned model 1911 when it comes to trigger pull/reset and natural pointing ability.
Once you get the hang of it, 1911-type pistols are also easy to field strip for cleaning. Here is a video showing how to disassemble and reassemble your model 1911:
Model 1911 Field Stripping and Reassembly
.45 ACP Ammunition Loading Guide
If you “roll your own” .45 ACP cartridges, there are many good powder choices. Our favorites are Vihtavuori N320, AA No. 5, and Hodgdon TiteGroup, but there are many other good choices. You’ll find these three recommended powders (plus seven others) in this .45 ACP Reloading Guide from Nosler:

Thinking of getting started in the Practical/Tactical shooting game? Looking for ways to be more stable when shooting from unconventional positions? Then you may want to read Marcus Blanchard’s Practical Shooter’s Guide (A How-To Approach for Unconventional Firing Positions and Training). Unlike almost every “how to shoot” book on the market, Blanchard’s work focuses on the shooting skills and positions you need to succeed in PRS matches and similar tactical competitions. Blanchard provides clear advice on shooting from barricades, from roof-tops, from steep angles. Blanchard says you need to train for these types of challenges: “I believe the largest factor in the improvement of the average shooter isn’t necessarily the gear; it’s the way the shooter approaches obstacles and how they properly train for them.”
Nancy Tompkins is one of the greatest long-range shooters in American history. She has won five National Long-range Championships. Tompkins’ treatise is a must-read for serious Palma, F-Class, and High Power shooters. The revised Second edition includes F-Class equipment and techniques, and newly updated information. Color pictures. Topics include Mental & Physical training, Reading Wind & Mirage Shooting Fundamentals, International Competition, and Loading for Long Range. Nancy Tompkins is a 4-time winner of the National Long Range Championships, and has won countless other major events. Nancy has been on six Palma Teams (as both a shooter and a coach).
Ryan Cleckner is noted for his ability to explain complex topics in an easy-to-comprehend manner. Now Cleckner has authored a book, the Long Range Shooting Handbook, which expands on the topics covered in Cleckner’s popular NSSF video series. The Long Range Shooting Handbook is divided into three main categories: What It Is/How It Works, Fundamentals, and How to Use It. “What It Is/How It Works” covers equipment, terminology, and basic principles. “Fundamentals” covers the theory of long range shooting. “How to Use It” gives practical advice on implementing what you’ve learned, so you can progress as a skilled, long range shooter. You can view Sample Chapters from Ryan’s Book on Amazon.com.
Tony Boyer, the most successful shooter in the history of short-range benchrest competition, shares many of his match-winning tips in this 323-page book.

This article, which originally appeared in the Sierra Bullets Blog, provides a new terminology that helps describe the geometry of bullets. Once you understand the meaning of “Caliber(s) of Ogive”, you can quickly evaluate potential bullet performance by comparing listed Caliber of Ogive numeric values.
by Mark Walker, Sierra Bullets New Product Development Manager
During one of our recent product releases, we listed the “caliber of ogive” of the bullet in the product description. While some understood what that number meant, it appears that some are not aware of what the number is and why it is important. In a nutshell, the “caliber of ogive” number will tell you how sleek the front end of the bullet is. The higher the number is, the sleeker the bullet. It also makes it easy to compare the ogives of different caliber bullets. If you want to know if a certain .308 caliber bullet is sleeker than a 7mm bullet, simply compare their “caliber of ogive” numbers.
So exactly how do you figure “caliber of ogive”? If you look at the drawing of the .30 caliber 175 gr HPBT bullet #2275 (at top), you will see that the actual radius of the ogive is 2.240. If you take that 2.240 ogive radius and divide by the diameter (or caliber) of the bullet you would get 7.27 “calibers of ogive” (2.240 ÷ .308 = 7.27). (See top photo).
In a nutshell, the “caliber of ogive” number will tell you how sleek the front end of the bullet is. The higher the number is, the sleeker the bullet.
Next let’s look at the print (below) of our 6.5mm 142gr HPBT #1742 bullet for comparison. The actual radius of the ogive is 2.756. Like with the .30 caliber 175 gr HPBT bullet #2275, if you divide 2.756 by the diameter (or caliber) of the bullet you get 10.44 “calibers of ogive”.
Some people would say why not just compare the actual ogive radius dimensions instead of using the “caliber of ogive” figure. If we were comparing only bullets of the exact same diameter, then that would be a reasonable thought process. However, that idea falls apart when you start trying to compare the ogives of bullets of different diameters. As you can see with the two bullets presented above, if we compare the actual ogive radius dimensions of both bullets the difference is not much at all.
However, once again, testing has shown that the 6.5mm 142 gr HPBT #1742 has a significantly higher BC. The only way that this significant increase shows up, other than when we fire the bullets in testing, is by comparing the “caliber of ogive” measurement from both bullets.
Hopefully this will help explain what we mean when we talk about “caliber of ogive” and why it’s a handy number to use when comparing bullets. This information will help you to make an informed decision the next time you are in the market to buy bullets.
Story tip from Grant Ubl. We welcome reader submissions.
AMP Annealing, the New Zealand-based manufacturer of advanced, computer-controlled annealing machines, has some new items in the works. First, AMP is bringing out a new, jumbo-sized pilot for the large .50 BMG case, which has a fat base diameter of 0.804″ (20.44 mm). The folks at AMP say: “The new 50-Caliber pilot is as large as the boss it screws into. We also had to add some insulation to the grip to stop it from heating up. We know a lot of your have been patiently waiting for the .50 Cal unit and we are on track for release early next year [2018].”
Along with the creating more pilot holders for brass, AMP is working on enhancing the performance of its annealing machines, offering even greater precision and efficiency. Here AMP engineers at the Auckland University of Technology test upgrades with AMP Annealing machines. AMP says: “Exciting times ahead… What’s new? We can’t say at this stage. But it will involve the use of your USB cable.”
.50 BMG — Just for the Fun of It All…
But back to the .50 BMG. Why would anyone want to shoot this beast? Well, because you can. It also offers excellent extreme long range performance. And nothing (well as least nothing civilians can purchase readily) beats the knock-down power of a big 50. This video shows what the .50 BMG can do to a truckload of pumpkins.

The anvil is the tripod-shaped thin metal piece protruding above the bottom of the primer cup. Getting the primer sitting fully flush on the bottom of the case primer pocket, without crunching it too much, requires some keen feel for the progress of primer seating.
In two recent Midsouth Blog articles, Glen Zediker offers helpful advice on priming. First he examines what happens to the primer itself as it is seated in the cup. Glen explains why some “crush” is important, and why you never want to leave a high primer. Glen also reviews a variety of priming tools, including his favorite — the Forster Co-Ax Bench Primer Seater. Then he offers some key safety tips. Glen provides some “rock-solid” advice about the priming operation. You’ll find more great reloading tips in Glen’s newest book, Top-Grade Ammo, which we recommend.
Priming Precision vs. Speed
Glen writes: “The better priming tools have less leverage. That is so we can feel the progress of that relatively very small span of depth between start and finish. There is also a balance between precision and speed in tool choices, as there so often is.”
Benchtop Priming Tools — The Forster Co-Ax
Glen thinks that the best choice among priming options, considering both “feel” and productivity, may be the benchtop stand-alone priming stations: “They are faster than hand tools, and can be had with more or less leverage engineered into them. I like the one shown below the best because its feeding is reliable and its feel is more than good enough to do a ‘perfect’ primer seat. It’s the best balance I’ve found between speed and precision.”
Load Tuning and Primers
Glen cautions that you should always reduce your load when you switch to a new, not-yet-tested primer type: “The primer is, in my experience, the greatest variable that can change the performance of a load combination, which is mostly to say ‘pressure’. Never (never ever) switch primer brands without backing off the propellant charge and proving to yourself how far to take it back up, or to even back it off more. I back off one full grain of propellant [when I] try a different primer brand.”
Priming Safety Tips by Zediker
1. Get a good primer “flip” tray for use in filling the feeding magazine tubes associated with some systems. Make double-damn sure each primer is fed right side up (or down, depending on your perspective). A common cause of unintentional detonation is attempting to overfill a stuffed feeding tube magazine, so count and watch your progress.
2. Don’t attempt to seat a high primer more deeply on a finished round. The pressure needed to overcome the inertia to re-initiate movement may be enough to detonate it.
3. Don’t punch out a live primer! That can result in an impressive fright. To kill a primer, squirt or spray a little light oil into its open end. That renders the compound inert.
4. Keep the priming tool cup clean. That’s the little piece that the primer sits down into. Any little shard of brass can become a firing pin! It’s happened!
Oversizing cases also causes problems because the firing pin doesn’t have the length to reach the primer solid enough to ignite it 100% of the time. When you have one that is oversized, you usually have a bunch, since you usually do several cases at a time on that die setting. If the die isn’t readjusted, the problem will continue on the next batch of cases also. They will either not fire at all or you will have a lot of misfires. In a bolt action, a lot of time the extractor will hold the case against the face of the breech enough that it will fire. The case gets driven forward and the thinner part of the brass expands, holding to the chamber wall and the thicker part of the case doesn’t expand as much and stretches back to the bolt face. If it doesn’t separate that time, it will the next time. When it does separate, it leaves the front portion of the case in the chamber and pulls the case head off. Then when it tries to chamber the next round, you have a nasty jam. Quite often range brass is the culprit of this because you never know how many times it has been fired/sized and in what firearm.’Back to beating it on the ground again till you figure out that you have to get the forward part of the case out.
