AccurateShooter.com is more about rifles than pistols. But we know that the majority of our regular readers own handguns, and many also have concealed carry (CCW) permits. And with the prospect of social unrest following the election, we expect more reader than ever will be “packing” a sidearm. Accordingly, we’ve found a great resource for CCW holders that can help you select a holster. On the Shooting Illustrated website you’ll find a detailed review of 30 different holster types. Each holster is illustrated, with pros and cons explained. These are all EDC holsters, meaning those designed for “Every Day Carry”.
Shooting Illustrated calls this article “HolsterPallooza” and it really does provide a ton of helpful information. Most other holster reviews on the web may feature a half-dozen holsters at the most. In this Holsterpallooza article you can see 30 holsters, with a wide variety of materials, designs, and applications. There are small molded IWB holsters for CCW, conventional on the belt holsters, leather shoulder holster rigs, and even ankle holsters. This is a great place to start if you are in the market for a holster.
Here’s sample of the many holster options reviewed, an innovative hybrid IWB holster constructed with leather over Kydex. That gives you the “best of both worlds” — the secure fit/retention of a molded Kydex shell, with an attractive leather exterior.
Shooting Illustrated explains: “As the interface between your gun and your body, the holster is a vital component of your carry rig. In many cases, the circumstances of your daily life will determine the method of carry you choose. This, in turn, will determine what type of holster you need, which may end up determining the handgun you carry. Therefore, choosing the method and type of holster may be as, or even more important than, choosing a firearm.”

While some shooting disciplines have moved to electronic targets, most shooting matches still use paper targets, which must have precise dimensions for the particular distance and discipline. If you need correctly-sized targets for specific shooting disciplines (such as NRA Smallbore, F-Class, and 1K Benchrest) check out the links in this article. Precise, dimensionally-correct competition targets are produced by a half-dozen specialty printers. In this article we provide links to the leading target sellers, with a chart showing “who’s got what”. Look for your particular discipline and the vendors will be specified.
Sources for Official Shooting Competition Targets:
AccurateShooter.com offers dozens of FREE, printable targets for target practice, load development, and fun shooting. We also offer a few of the most popular NRA Bullseye targets. One or more of these printable targets should work for most training purposes. However, some readers have asked: “Where can we get the real targets… exactly like the ones used in NRA, IBS, and NBRSA shooting matches?”
All these vendors carry nearly all the NRA High Power and Smallbore targets, including the smaller F-Class targets. National Target has the F-Class and High Power targets, including 100-yard reductions of the 200, 300, and 600-yard military targets.
Here are some of the air rifle, smallbore, and High Power targets at Creedmoor Sports:
Orrville Printing currently sells IBS targets for rimfire (50 yard) benchrest, short-range centerfire Benchrest (100, 200, 300 yards), Hunter BR Rifle (100, 200, 300 yards), plus the official 600-yard and 1000-yard IBS targets. National Target Company also has most of the IBS targets. NBRSA short-range, 600-yard, and 1000-yard benchrest targets are available directly from the NBRSA Business Office.

“A bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, the bullet behaves as if it has a higher ballistic coefficient.”
A few seasons back a good friend ventured to the high country of Colorado to pursue elk. He recently zeroed his rifle in California, at a range just a few hundred feet Above Mean Sea Level (AMSL). He wondered if the higher altitude in Colorado could alter his ballistics. The answer is a definite yes. However the good news is that free ballistics calculators can help you plot reliable drop charts for various shooting locations, high or low.
The question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.
Forum member Milanuk explains that the key factor is not altitude, but rather air pressure. Milanuk writes:
“In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ AMSL (Above Mean Sea Level) or less. I’ll need about 29-30 MOA to get from 100 yards to 1000 yards with a Berger 155gr VLD at 2960 fps. By contrast, in Raton, NM, located at 6600′ AMSL, I’ll only need about 24-25 MOA to do the same. That’s a significant difference.
Note that it is the barometric pressure that really matters, not simply the nominal altitude. The barometric pressure will indicate the reduced pressure from a higher altitude, but it will also show you the pressure changes as a front moves in, etc. which can play havoc w/ your calculated come-ups. Most altimeters are simply barometers that read in feet instead of inches of mercury.”
As Milanuk states, it is NOT altitude per se, but the LOCAL barometric pressure (sometimes called “station pressure”) that is key. The two atmospheric conditions that most effect bullet flight are air temperature, and barometric pressure. Normally, humidity has a negligible effect. It’s important to remember that the barometric pressure reported on the radio (or internet) may be stated as a sea level equivalency. So in Denver (at 6,000 feet AMSL), if the local pressure is 24″, the radio will report the barometric pressure to be 30″. If you do high altitude shooting at long range, bring along a Kestrel, or remember to mentally correct the radio station’s pressure, by 1″ per 1,000 feet.
Trajectory of Bullet fired at Sea Level
Trajectory of Bullet fired at 20,000 feet
You can do your own experimental calculations using JBM Online Ballistics (free to use). Here is an extreme example, with two printouts (generated with Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.
To learn more about all aspects of Exterior Ballistics, Hornady has a useful discussion of External Ballistics including the effects of altitude and temperature. To dig deeper, Sierra Bullets has a comprehensive Exterior Ballistics Resource Page with multiple sections from the Sierra Manual (4th and 5th Editions), including:
Example from Section 3.0: “When a bullet flies through the air, two types of forces act on the bullet to determine its path (trajectory) through the air. The first is gravitational force; the other is aerodynamics. Several kinds of aerodynamic forces act on a bullet: drag, lift, side forces, Magnus force, spin damping force, pitch damping force, and Magnus cross force. The most important of these aerodynamic forces is drag. All the others are very small in comparison when the bullet is spin-stabilized.”
Gunsmith/stockmaker Doan Trevor created a lovely, one-of-a-kind silhouette stock for an Anschutz rimfire action. Built as a true custom design, this stock combines ideal standing position ergonomics with light weight — the entire stock weighs a mere two pounds. This project really showcases Doan’s remarkable skills with wood. Read the full story about this project (with more photos) at DoanTrever.com.
Doan explains his design process: “A customer came to me wanting to know if I could build a silhouette stock that was 2 pounds or less. I used the Koa wood because it is a lower specific gravity than Walnut (which makes it lighter) and stronger. I was still able to use pillar bedding and keep the weight down. The fore-end could be shortened to reduce the weight even more.
Since the drops on a silhouette rifle are different than a prone rifle, I kept the pistol grip from the prone rifle which is comfortable and tried to come up with a higher cheek piece and more drop to the buttplate. All of this required lots of hand carving.”
The USA F-Class National Championships are underway right now in Lodi, Wisconsin. The Mid-Range Championships run August 10-13, 2024, while the Long Range F-Class Championships start on the 14th and run through August 17, 2024. With the Mid-Range event underway today, as you read this, top F-Open and F-TR shooters are aiming their rifles at 600-yard targets. VIEW Nationals Match Program HERE.
2024 NRA F-CLASS NATIONAL CHAMPIONSHIPS
NRA F-CLASS MID-RANGE NATIONAL CHAMPIONSHIP AUGUST 10-13, 2024
NRA F-CLASS LONG RANGE NATIONAL CHAMPIONSHIP AUGUST 14-17, 2024
Event hosted by Winnequah Gun Club and sponsored by Brux Barrels, Criterion Barrels, Krieger Barrels, and Silver Mountain Target.
There will be two divisions at The F-Class National Championships: F-Open and F-TR. In F-Open the rifles can shoot any cartridge type (up to .35 caliber) and have a 22-lb (10kg) weight limit. A front rest is allowed, and most shooters favor a rest with a joystick control.
In F-TR, two cartridge types are allowed: .223 Remington (5.56×45) or .308 Winchester (7.62×51 NATO), with no restrictions on bullet weight. F-TR rifles are fired off a bipod attached to the rifle’s fore-end. The F-TR weight limit is 8.25 kilograms, or about 18 pounds. This includes the weight of the rifle, scope, and bipod. A sandbag can be used under the rear of the stock. Because of the lower weight limit, which includes the bipod, F-TR stocks tend to be much slimmer and lighter than F-Open stocks which have wide fore-arms to work with the front rests.
F-Open Cartridge Options — Modern Magnum Options
For Today’s Sunday Gunday Story we feature an article about F-Open chamberings by respected rifle builder and past F-Open National Champion Emil Kovan. In this article, Emil reviews some of the new magnum cartridge options that are being employed by F-Open competitors. Many shooters are still using the .284 Winchester (or variants), but an increasing number are shooting 7mm and .30-caliber cartridges based on magnum cartridge types. The 7mm is probably still the favored caliber for F-Open because 7mm bullets offer great ballistics with less recoil than heavier .30-caliber projectiles.
Cartridges for F-Class Part II — Rise of the Magnums
A few seasons back, I wrote an article on cartridge choices for F-Class shooters. CLICK HERE to READ ARTICLE. Since the first article I wrote, F-Class has continued to grow, and push the limits of precision and accuracy. While the .284 Win and its variants are still the most common F-Open cartridges, more and more top F-Open shooters are using magnum cartridge types to win competitions and set new records. In this article, I will list some of the advantages and disadvantages of the most commonly used magnums, and will cover the strengths and weaknesses of each one of them.
Performance factors we will consider for magnum F-Open cartridges include:
1. Equal or better accuracy than standard chambers
2. Better ballistic performance
3. Enhanced case life
4. Barrel life
Accuracy Potential of Magnum Cartridges for F-0pen Competition
John Meyrs has won four National Mid-Range Championships using the .300 WSM. Tim Vought used the same cartridge to win two Mid-Range Nationals and used a 7-6.5 PRC to win the long range Nationals. Standard .437″ case head (.308 Win head size) cartridges still have more Nationals wins overall, but the magnums are quickly catching up, and my prediction is that magnums will dominate soon.
The accuracy and precision potential of magnums used in F-Class (.300 WSM, 7-270 WSM, 7mm RSAUM or “7 SAUM”, 7-6.5 PRC) is better than non-magnum cartridges because their shapes are closer to the ideal “fat/short” body associated with wider nodes and extreme precision. For example a .300 WSM is proportionally much closer to the 6 PPC, 6 Dasher, and 6 BRA than is the .284 Winchester.

The first thing that comes to mind when magnums are discussed is power and speed. In my humble opinion most shooters are missing out on accuracy because they push their magnums right past the most stable and accurate nodes. Recently I met my good friend from the Army Marksmanship Unit, SFC Brandon Green, at a shooting competition. We discussed the latest and greatest in long-range shooting. I knew that the USAMU had switched from 6.5-284 Norma to 7mm RSAUM several years back, but didn’t know what load they are currently using. Brandon told me that the load featured Berger 180gr hybrids in Nosler cases at 2820 fps. We all know that the 7 SAUM is capable of much higher speeds, “but at around 2820 fps the load/rifle combo will hammer the X-Ring anywhere under any conditions” SFC Green said.
F-Open rifles on the firing line at the Ben Avery Shooting Facility in Phoenix, Arizona.
Most shooters jump right into magnum territory velocities when testing, missing out on better precision at standard chamber speeds. For example, my 30 KMR can easily reach 2880 fps with 230gr Hybrids, and it actually shoots pretty good. But the same rifle at around 2770 fps will absolutely hammer the X-Ring in any condition anywhere. When it’s all said and done, F-Class is a long-range shooting competition at a known distance which requires extreme precision and accuracy. It is not a speed race.
IMPORTANT — Case-Head Dimensions Do Make a Difference
Magnums, when shot within reasonable velocities, on average will give better case life due to the bigger case + lower pressure and “more meat” in the case-head area. For example a 7 SAUM case will outlast a .284 Win case when both are loaded to around 2900 fps.
Disadvantages of Magnum F-Open Cartridges
Perhaps the biggest disadvantage linked to magnums is recoil. Some people complain about developing the “gun shy” syndrome after shooting a magnum for a while. Muzzle blast and recoil are significantly more pronounced in magnums, but that can be easily managed with a properly-built rifle equipped with appropriate recoil mitigation hardware such as RAD and the various butt plates.

Barrel Life — “Barrels are Expendable Components”
It is true that certain magnums can torch a barrel in just a few hundred rounds. But the same is true when improving a 6BR to 6 Dasher for example — barrel life might be reduced significantly. More powder = more heat = diminished accuracy after a certain round count. In my experience, a F-Open magnum’s barrel life is very close to high-performance standard cartridges such as the .284 Shehane or .284 KMR. I “retire” my barrels around 1200 rounds regardless of the cartridge being a magnum or not. After that many rounds most barrels will still shoot OK but will copper up, and you will start seeing those unexplained vertical 9s. The bottom line is this, barrels are expendable components very much like brass. You can’t get the performance of .300 WSM and the barrel life of the .308 Win at the same time. If you want to race in NASCAR, fuel mileage should not be the top priority!
Top Magnum Cartridge Types Used in F-Class Open Division
.300 Winchester Short Magnum
The .300 WSM (Winchester Short Magnum) tops the popularity chart in F-Class Open division. It has been used to win numerous National championships and has set many National records. The .300 WSM’s short/fat case shape, with minimal body taper and 35-degree shoulder, contribute greatly to its outstanding performance at long range. Components are readily available as well. Best brass remains to be Norma, although ADG is just as good and some would even say better, but it is more expensive and harder to get at this time.
The .300 WSM has been described as a “super-sized Dasher”.
For the .30-cal magnums, in my opinion, the best bullets by far are made by Berger. If your rifle does not shoot 215gr, 230gr hybrids, or 210gr VLDs well, you likely have a rifle problem, NOT a bullet issue. My “go to” bullet is the Berger 230gr Hybrid. The 215-grainer is a close second, followed by Berger’s accurate but ballistically inferior 210gr VLD, which I use in calm and steady conditions.
Top powders for the .300 WSM are Hodgdon H4831SC and H4350. I know there are many more powders suitable for the .300 WSM cartridge, but none I have used can match Hodgdon’s consistency when shot in different geographical locations and weather conditions.
7mm Remington Short Action Ultra Magnum
The 7mm RSAUM (aka 7 SAUM) used to be the darling of F-Open. Its case capacity and shape are about perfect for launching 180gr pills with great ballistics and precision. Its popularity faded a little, due to the lack of good brass, and the rise of the improved versions of the .284 Win which can almost match the RSAUM performance. Norma still makes 7 RSAUM brass which is pretty good but little on the soft side and hard to find. ADG is arguably producing the best RSAUM brass right now. It is very uniform, reasonably priced, and seems to hold up very well even when pushed hard. The best bullets are again made by Berger, and those are the 180gr hybrid, 184gr hybrid, and 180gr VLD. Best powders are H4831sc, H4350, and Alliant Reloder 16 and Reloder 23.
7-270 WSM, 7-300 WSM, and 7 WSM
The first two are pretty much identical, the only difference being that the 7-270 WSM is necked up .270 WSM while the 7-300 WSM is a .300 WSM necked down to 7mm. I personally prefer the first one since necking-up is easier than necking-down (with fewer doughnut issues).
The WSM case-based 7mms will give you great velocity flexibility as well as superb precision when tuned well. In the 2013 world championship in Raton NM, I was scoring for a gentleman from Canada who was shooting 7-270 WSM. The wind was blowing pretty hard that day. On one of his shots, just before he pulled the trigger the wind gusted. I remember thinking that’s going to be an 8 for sure. The target came up a line 10! I asked him after the match what he was shooting, and he replied 180s at 3100fps. Although capable of such speeds, I think that potentially better and more consistent accuracy can be achieved at much slower speeds. The best powders and bullets are again Hodgdon and Berger respectively. Best cases are made by Norma and ADG, with Winchester being a third option.
7-6.5 PRC — Popular Wildcat
Last but not least on our chart is the 7-6.5 PRC. This particular cartridge is actually a wildcat. It is a 6.5 PRC necked up to 7mm. It is pretty much identical to the 7 RSAUM with the only differences being a shorter neck and .01″-narrower body. Currently the 7-6.5 PRC is the most requested cartridge that I offer when building new rifles. It seems to fill the gap between the .284 Win and the larger magnums very nicely. It is capable of reaching 3000fps but most shooters are getting their best results around 2920-2950 fps. The biggest advantage of this wildcat is brass. Lapua makes super high-quality, readily-available 6.5 PRC brass. Best powders are H4831sc, H4350, Reloder 16, and Vihtavuori VV 555. The best bullet in my opinion is the 180gr Berger. I am yet to hear about a better-performing bullet in this chamber.
Conclusion In conclusion, magnums are not perfect but their performance advantages should be very seriously considered when building a rifle for long-range F-Class. In part three, I will list the most common wildcat magnums, and present the KMR magnums which will make you (if you haven’t already) buy a magnum action and get a magnum build for sure!

Sam (L.E.) Wilson actively competed in benchrest matches until he passed. He’s shown here with an Unlimited benchrest rifle of his own design.
If you’ve used hand dies with an arbor press, chances are you’ve seen the L.E. Wilson company name. You may not know that the founder of L.E. Wilson Inc. was an avid benchrest competitor who pioneered many of the precision reloading methods we used today. Known as “Sam” to his friends, L.E. Wilson was one of the great accuracy pioneers who collected many trophies for match victories during his long shooting career. His company continues to innovate — bringing out new products such as the Case Gage Depth Micrometer tool.
The photo above shows Sam (foreground) with all of his children at a shoot. Behind Sam are Jim, Jack and Mary, shooting in the Unlimited Class. What do they say — “the family that plays together stays together”? Note the long, externally-adjusted scopes being used. Learn more about Sam (L.E.) Wilson and his company on the L.E. Wilson website.
Unlimited Class was Sam’s favorite discipline, because in the “good old days” top competitors normally would craft both the rifle and the front/rear rests. This rewarded Sam’s ingenuity and machining/fabrication skills. In the “build-it-yourself” era, one couldn’t just order up an unlimited rail gun on the internet. How times have changed…
It’s summertime, 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.
[One summer] 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.
This varmint ammo, with thrown charges, put TEN shots inside ONE inch at 200 yards. That’s half MOA. Good Enough? Absolutely!
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 above.] 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.
A while back, Sinclair International’s Reloading Press Blog featured a “round-table” discussion of reloading techniques. Sinclair’s team of tech staffers were asked: “What do you feel is the one-most crucial step in precision reloading?”
Here are their responses (along with comments from our Editors):
Phil Hoham: “I feel that when working up a load do not go too high or too low in your powder charge. Stay away from ‘suggested loads’ you hear at the range, or on the internet. Always be sure to use a published reloading manual that presents not only minimums and maximums, but also pressure, velocity, and a proper range of powders used. Do not get distracted in the reloading process, and remain focused at all times during each step involved.”
AccurateShooter.com: Some loads presented on the Internet are OK as a starting point, but it is absolutely critical to understand that pressure maximums will vary considerably from one rifle to another (of the same chambering). For example, one 6mmBR rifle shooting 105gr bullets can max out with 30.0 grains of Varget powder, while another rifle, with the same chamber dimensions, but a different barrel, could tolerate (and perform better) with half a grain more powder. You need to adjust recommended loads to your particular rifle and barrel.
Pete Petros: “This could be a very broad topic, but if I were to pick one, it would be making sure to pay close attention, and weigh each and every powder charge to ensure that each load is exact and consistent. This is important not only for accuracy, but also for safety reasons.”
AccurateShooter.com: If you’re shooting beyond 200 yards, it is critical to weigh your loads with an accurate scale or automated system such as the AutoTrickler V3/V4. Loads that are uniform (within a few kernels) will exhibit lower Extreme Spread and Standard Deviation. And remember, even if you stick with the same powder, when you get a new powder lot, you may have to adjust your load quite a bit. For example, .308 Palma shooters have learned they may need to adjust Varget loads by up to a full grain from one lot of Varget to the next.
Ron Dague: “I feel that the most important step(s) in reloading for accuracy are in the initial case prep. Uniforming the primer pocket to the same depth to ensure consistency in primer seating is a crucial step. Additionally de-burring the flash holes, each in the same way to clean up and chamfer the inside is important. It ensures that the ignition from the primer is uniform and flows out in the same consistent pattern. Doing so will create uniform powder ignition and tighten up your velocity Extreme Spread.”
AccurateShooter.com: With some brands of brass, primer pocket uniforming and flash-hole deburring is useful. However, with the best Lapua, Norma, and RWS brass it may be unnecessary, or worse, counter-productive. So long as your Lapua brass flash-holes are not obstructed or smaller than spec, it may be best to leave them alone. This is particularly true with the small flash holes in 220 Russian, 6BR, and 6.5×47 cases. MOST of the flash-hole reaming tools on the market have cutting bits that vary in size because of manufacturing tolerances. We’ve found tools with an advertised diameter of .0625″ (1/16″) that actually cut an 0.068″ hole. In addition, we are wary of flash-hole deburring tools that cut an aggressive inside chamfer on the flash-holes. The reason is that it is very difficult to control the amount of chamfer precisely, even with tools that have a depth stop.
Rod Green: “I feel that bullet seating is the most important step. If you had focused on making sure all prior steps (case prep, powder charge, etc.) of the process have been carefully taken to ensure uniformity, bullet seating is the last step, and can mean all the difference in the world in terms of consistency. Making sure that the bullet is seated to the same depth each time, and time is taken to ensure that true aligned seating can make the load.”
Bob Blaine: “I agree with Rod. I strongly feel that consistent bullet seating depth is the most important step in creating the most accurate hand loads. I have seen the results in both my bench and long range rifles. Taking the time to ensure exactness in the seating process is by far, the number one most important step in my book.”
AccurateShooter.com: Agreed. When loading match ammo, after bullet seating, we check every loaded round for base of case to ogive length. If it varies by more than 3 thousandths, that round is segregated or we attempt to re-seat the bullet. We measure base of case to bullet ogive with a comparator mounted on one jaw of our calipers. You may have to pre-sort your bullets to hold the case-base to ogive measurement (of loaded rounds) within .003″.
A while back, RifleShooter online magazine published a list of the purported Ten Best Bolt-Action Rifles of All Time. Ten classic rifle designs (including the Remington 700, Winchester Model 70, Weatherby V, and Mauser 98) were featured with a paragraph or two explaining their notable features.
“Best” Lists Stir Controversy…
These Top 10 lists are always controversial. While most readers might approve of half the entries, there are always some items on the Top 10 list that some readers would challenge. Here is RifleShooter’s Top 10 list. What do you think? Are there some other bolt-actions that are more deserving?

“Science tells us that exposure to continuous noise of 85 dB for eight hours is enough to cause permanent hearing loss, and worse, spikes of 130 dB and more can result in permanent hearing damage instantly.” Source: NRA Blog.
The Risk of Hearing Loss
Hearing loss can be progressive and irreversible. If you are a shooter, this is serious business. As the NRA Blog cautions: “You may not even realize you’re harming your hearing. Hearing loss occurs gradually, and can go effectively unnoticed until symptoms become severe. By then, the damage is done.”Effective hearing protection is a must whenever you are shooting firearms or when you are in the vicinity of gun-shots. For ultimate protection, we recommend a good set of tapered foam earplugs, topped by ear-muffs. However, there are situations when you may prefer lighter-weight hearing protection that can be quickly removed. For example, if you are standing well behind the firing line as an observer, or if you are working as a rangemaster or waddie some distance away from the shooters.”
Sound Levels for Common Noises:
9mm Luger pistol: 160 dB
Jet aircraft engine (near): 140 dB
.22 LR pistol: 134 dB
Normal human pain threshold: 120 dB
Noisy Nightclub: 110 db
Riding Motorcycle at 65 mph: 103 db
Power Lawnmower: 95 dB
Hearing damage possible: 85 dB (sustained for 8+ hours)
Ringing Telephone: 80 dB
Normal conversation: 60 dB
What about suppressors? If you use a suppressor is it OK to dispense with hearing protection? Not really. Even the most effective suppressors, on the smallest and quietest calibers (.22 LR), reduce the peak sound level of a gunshot to between 110 to 120 dB. To put that in perspective, according to the National Institute for Occupational Safety and Health (NIOSH), that is as loud as a jackhammer (110 dB) or an ambulance siren (120 dB). For normal caliber handguns and rifles, suppressed sound levels routinely exceed 130 dB, just shy of OSHA’s “hearing safe” threshold of 140 dB. Accordingly, we recommend use of hearing protection even when shooting suppressed.
Compact, Low-Profile NRR 27 dB-Rated Ear Muffs
Many hunters and competitive shooters prefer low-profile ear muffs. As these typically have a lower Noise Reduction Rating, perhaps NRR 22-27, we recommend running earplugs under muffs. If you use low-profile electronic muffs, such as Howard Leight Impact Sport Muffs, you should still be able to hear range commands even with plugs underneath.
Another good option for hunters and range visitors are hearing bands, basically earplugs connected with a semi-rigid plastic band. These banded products provide “quick access” hearing protection for hunters. You can keep them handy around the neck while spotting game, and then insert the plugs before shooting.
Howard Leight MAX NRR 33 Earplugs, Just $8.44 for 20 Pairs
These Howard Leight NRR 33 Max-1 Plugs are your Editor’s favorite foam earplugs. Between shooting, motorcycling and mowing lawns, I probably have Howard Leight foam plugs in my ears 3-4 days a week. They are comfortable and the flared outer edge helps the NRR. You can get 20 pairs for $8.44 on Amazon. There is also a Max-30 corded version, with the same excellent 33 dB Noise Reduction Rating. Get five pairs of Max-30 Corded Plugs for $5.99 on Amazon, or 100 pairs of Max-30s for $27.99.
Note, if you prefer thin, light-weight earmuffs, we recommend running earplugs underneath for double protection while shooting firearms (or when you’re on the firing line). Sound experts tell us that running plugs and muffs together can effectively improve your effective noise reduction by 4-7 dB NRR.
The question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.
There will be two divisions at The F-Class National Championships: F-Open and F-TR. In F-Open the rifles can shoot any cartridge type (up to .35 caliber) and have a 22-lb (10kg) weight limit. A front rest is allowed, and most shooters favor a rest with a joystick control.
In conclusion, magnums are not perfect but their performance advantages should be very seriously considered when building a rifle for long-range F-Class. In part three, I will list the most common wildcat magnums, and present the KMR magnums which will make you (if you haven’t already) buy a magnum action and get a magnum build for sure!
A while back, Sinclair International’s Reloading Press Blog featured a “round-table” discussion of reloading techniques. Sinclair’s team of tech staffers were asked: “What do you feel is the one-most crucial step in precision reloading?”
