We are very sad to report that G. David Tubb, one of the greatest marksmen who ever lived, passed away on Thursday, July 2, 2026 in the afternoon. David, who was 71, died from heart and blood oxygen issues following surgery to remove one leg at the knee. The amputation procedure followed serious major problems from multiple knee replacements in the past.

David was, without question, one of the most talented and successful marksmen in history. David recorded 11 High Power Rifle Championships, 6 Long Range National Championships, and 7 High Power Silhouette National Championships. Over his career David won 130 NRA trophies for various competitions. No one has even come close to that number of Championships and honors in rifle competition.

A close friend of David, James Schmidt, recently posted: “Legendary firearms shooter David Tubb has left the range. David was an incredible innovator in the firearms industry and was credited in every way with many many excellent creations for shooters all over the world. His love for the industry and extreme accuracy shooting is unsurpassed at any level. His personal shooting skills will remain in history as amazing, remarkable and at times unbelievable! Perhaps his shooting accomplishments will never ever be achieved again.”

As a cartridge case is reloaded multiple times, burnt powder residue and carbon builds up on the inside of the case. Unless the case interior is cleaned in some fashion, eventually you’ll see a slight reduction in case capacity. One of our Forum members from Australia wonders about the effects of reduced case capacity: “If the capacity of the case decreases as the crud builds up, then it effectively reduces the size of the cartridge (inside). Wouldn’t that change the pressure produced from that of an equivalent clean case?”

Interesting Test of Case Capacity Changes
Forum member Fred Bohl has actual test results that can help answer the above question. Fred proved that, over a 20-reload cycle, the case capacity of uncleaned cases did decline a small amount. However, surprisingly, this did not seem to affect the actual chronographed velocity of the load. Extreme Spread (ES) did increase, but Fred believes the higher ES was due to changes in case-neck tension, rather than due to the slight reduction in case capacity. Fred reports:

“Back when beginning to use ultrasonic case cleaning, part of the motivation was to get the inside clean based on the assumption that allowing burnt residue to build up inside cases would affect capacity, and, ultimately, performance. An experiment was done to test this hypothesis. The load used, 30.5 grains of RL15 behind 107gr SMKs in a 6mmBR, was selected for best group and lowest ES in prior load development. It turned out to be 92% of initial case capacity and neither “full” or compressed. (I would suspect that different powders, load weight, and total case capacity might produce very different results.)

We took 30 cases of identical initial capacity and tracked three lots of 10 each:

LOT 1: No Internal cleaning
LOT 2: Cleaned with media in tumbler
LOT 3: Cleaned with Ultrasound machine

Each case (in each lot) was shot and reloaded 20 times. The simplified results after 20 reloads of each lot were as follows:

Lot 1 (not cleaned) – 0.3 to 0.4 gr. loss of capacity, 5 to 8 fps greater ES.
Lot 2 (tumble cleaned) – 0.1 to 0.3 gr. loss of capacity, 4 to 6 fps greater ES.
Lot 3 (ultrasonic cleaned) – no loss of capacity, no detectable change in ES.

FINDINGS
There was no detectable correlation of velocity change to the lots. An oddity was that on very hot days Lot 1 velocities were, occasionally, slightly higher. From results of another ongoing test, I believe the above differences in ES are probably due more to variance in bullet grip tension than case capacity. The ultrasound cleaned cases (LOT 3) did maintain the lowest ES, but we are not 100% sure of the reasons why. More consistent bullet seating might be the reason.”

Editor’s NOTE: Fred’s results do suggest that carbon build-up inside the uncleaned cases might cause a slight increase in pressure that shows up on hot days. Fred has posted that: “A local shooter reported doing the 20 reload, no-clean test on a .308 that gave a loss of capacity of 2.0 grains, doubled ES and significant velocity changes. However, I don’t have any details on his load weight or powder.” Obviously a lot of carbon can build up with 20 reloads. Many shooters retire their brass before then.

Ultrasonic Cleaning and Neck Lube
Some time ago, Jason Baney did a lengthy test on ultrasonic cleaning. Jason found that with his ultrasonically-cleaned cases, the inside of the necks got so “squeaky clean” that he needed to use dry lube in the necks. Jason uses the dry lube kit from Neconos.com. This applies ultra-fine Moly powder to the neck interior using small carbon steel balls.

Widener’s Reloading & Shooting Supply has published a helpful introduction to reloading powders. Widener’s online Guide to Smokeless Powders shows the various types of powders, and explains how the differences in powder kernel/flake size and shape, and burn rate affect performance. We recommend you visit Widener’s website and read the Powder Guide in full.

Take a close look at these illustrations which show the key differences between the four main powder types: extruded (stick) powder, ball (spherical) powder, flattened ball powder, and flake powder.

Burn Rate Basics

Widener’s Guide to Smokeless Powders also has a useful discussion of Burn Rate (a confusing topic for many hand-loaders). Wideners explains: “While a gun powder explosion in the cartridge seems instantaneous, if you slow it down you will actually find that each powder has a different ‘burn rate’, or speed at which it ignites.” This video shows powders with two very different burn rates. Watch closely.

Different burn rates suit different cartridge types notes Widener’s: “In general a fast-burning powder is used for light bullets and low-speed pistols and shotguns. Medium-rate powders are used for magnum pistols, while high-velocity, large bore rifle cartridges will need slow powders[.]

It should be noted that burn rate does not have a standardized unit of measurement. In fact, burn rate is really only discussed in comparison to other powders; there is no universal yardstick. Specifics will change by cartridge and bullet types[.]”

Serious riflemen know that Krieger makes outstanding centerfire barrels that hold world records and have won many National Championships. But did you know that Krieger makes great rimfire barrels too? Well, Krieger does make outstanding .22 LR rimfire match barrels that can deliver impressive accuracy.

Sniper’s Hide moderator “Padom” recently tested a variety of rimfire ammo types, employing five different barrels: Krieger, Bartlein, Benchmark, Lilja, and Green Mountain. He tested at both 50 yards and 100 yards. FULL Rimfire TEST REPORT HERE.

Reporting on the 50-yard test, Padom posted: “Had a virtually dead calm day today for 50-yard RimX testing (Keystone Accuracy RimX barreled action with 1:16″ Krieger 20″ barrel). A few infrequent 3 mph gusts but pretty dead [calm] and the target showed. This Krieger just barely edged out the Bartlein by 0.003″ with a 0.177″ 6×5 with SK Rifle Match. The 10×5 was 0.198″. The best lots of Center-X weren’t far behind either. This is the first Krieger rimfire [barrel] I’ve shot and it didn’t disappoint.”

Padom noted: “Winds were much calmer tonight than this morning so the 100-yard Krieger test was a success. Winds were pretty consistent [at] 3-5 mph.”

Test Results at 100 Yards
Padom then tested ammo at 100 yards, again using his Krieger rimfire barrel: “To recap, the Krieger shot the best 50-yard results of the barrels tested so far, just barely beating the Bartlein but it was so close you can call the 50-yard results equal (.005). Well the Krieger beat all the barrels tested to date at 100 yards by a pretty good margin with Center-X. The 10×5 was incredible as well at just barely over 0.6″ showing the results were very consistent. A second lot of Center-X was right there with the previous 100-yard 6×5 best results just barely over 0.6. The third lot of Center-X shot a respectable 0.75″ 6×5. This Krieger sure is shooting very nicely. I’m really looking forward to shooting it at 300 and 400 yards[.]”

Components Tested: 20″ Krieger M24 barrel, .22 LR Match Eachus chamber 0.046 headspace, Zermatt RimX Action, Bix’N Andy TacSport Pro 2-Stage Trigger, RimX 10rd magazine, XLR Envy Pro Folding Chassis, Athlon Cronus BTR 4.5-29x56mm MIL scope.

Shooting Set-up: 100 Yards Prone with Bipod and Rear Bag.

On some internet shooting forums, self-declared “experts” advise new rifle shooters to stick to low-end factory rifles. These “experts” (many of whom don’t own a single really accurate rifle), claim that it will take years for a new shooter to learn how to shoot a rifle accurately. So, the argument goes, the accuracy offered by a precision-chambered rifle, with a custom barrel, is “wasted” on a new shooter.

We disagree with that viewpoint, at least when it comes to rifles shot from a rest. We’ve seen relatively new shooters, with help from a skilled mentor, do remarkably well with precision rifles right from the start. With a good bench gun, many new shooters can shoot well under 1 MOA on the first day. Certainly it takes time for a complete novice to learn how to handle the gun and to work the trigger smoothly. However, this editor has personally seen some inexperienced shooters try their hand at benchrest shooting, and within few month they are doing very well indeed at club shoots.

Accurate Rifles Reward Progress As Novices Build Skills

For bench shooting, we think a highly accurate rifle is a much better training device for a new shooter than a typical, cheap factory sporter. With a gun capable of 1.5-2.0 MOA at best, you can never really determine if a “flyer” is you or the gun. Conversely, when a novice shoots a gun that can put 5 shots through one ragged hole, if a shot goes way high or low, the shooter knows his aim, trigger control, or gun-handling is to blame. He (or she) can then correct the problem. And when the shooter does everything right, he or she will see a nice tight group on the target. The accurate rifle provides more meaningful feedback and it rewards progress. That helps the novice become a better shooter in a shorter period of time.

A while back, Forum Member Preacher and his “bunny hugger” niece from California proved this point. The young lady, with almost no shooting experience, took Preacher’s 6-6.5×47 and shot a sub-quarter-MOA, 3-shot group at 350 yards. Don’t tell her she needs to stick to a cheap factory rifle. Preacher reports: “My niece flew in from the west coast and came up to visit. When she saw a few of my full-blown varmint rifles, she wanted to shoot one. She did a super job even if she IS a ‘bunny hugger’. She pulled the 1.5 ounce Jewell on a few fired cases to check out the trigger pull and then got in behind the gun and put three shots into a 350-yard target with a one-inch circle.” We measured her group at 0.822″ (0.224 MOA). Don’t tell Preacher that accuracy is “wasted” on novices. He joked: “I sure don’t want her shooting at me ….”

Rifle Features BAT Action, Krieger Barrel, and Russo Laminated Stock:

For those who are interested, Preacher’s rifle features a BAT 3-lug action, 30″ Krieger 7.5-twist heavy contour barrel, and Russo stock (with clear coat by Preacher). Chambered in 6-6.5×47 Lapua, this gun “shoots the 108gr Bergers very well” according to Preacher. Yep, we agree with that — even when a novice “bunny-hugger” does the trigger-pulling.

Protect Your Hearing — Wear Protection Whenever You Shoot

Noise-induced hearing loss and tinnitus are two of the most common afflictions for recreational shooters and hunters. Everyone knows that gunfire is loud, but very few people understand the repercussions that shooting can have on their hearing until it’s too late.

The better quality suppressors can reduce the noise of a gunshot by 20 to 35 decibels (dB). Good muffs or plugs will reduce sound by 23 to 33 dB. By decreasing the overall sound signature, suppressors help to preserve the hearing of recreational shooters and hunters. 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.

According to Dr. William W. Clark, the current Director of the Washington Univ. School of Medicine’s Audiology/Communication Sciences Program, a “serious threat to hearing comes from recreational hunting or target shooting”. This is in large part due to the fact that many people choose not to use traditional hearing protection devices like earplugs and earmuffs because they want to be able to hear their surroundings. Multiple studies have found that between 70 to 80% of hunters never wear earplugs or earmuffs, and nearly half of all target shooters don’t consistently wear traditional hearing protection. Thus, it should come as no surprise that for every five years of hunting, hunters become seven percent more likely to experience high frequency hearing loss.

This article is based on information from the American Suppressor Association (ASA). Since the ASA’s formation in 2011, three additional states have legalized suppressor ownership and 18 states have legalized suppressor hunting. For more information, visit www.AmericanSuppressorAssociation.com.

With the United States of America’s 250th birthday coming on July 4, 2026, just six days from now, we are featuring a handsome F-Class rifle with a patriotic theme. This rifle has the historic “We the People” phrase painted on its handsome Cerus stock. The phrase “We the People” is the famous opening to the Preamble of the U.S. Constitution. Adopted on September 17, 1787, this preamble indicates the government derives its political power directly from its citizens rather than from a monarch or government officials. This cool rig also features the U.S. Stars and Stripes flag on the buttstock.

Rifle Report by Jason Cohen
The rifle began its life as a Will McClosky Cerus stock. I approached Will at the Berger SW Nationals about a rifle I wanted to build. I wanted to do something different — PAINT it. He said he had just the stock that I could use, and sent that to Bryan Blake at Blake Machine. I chose Bryan for two reasons — first, I have shot with him a few times at National matches and he is approachable and very helpful. Second I visited his shop during the SWN in February and liked what I observed and how he approached things. Bryan never seems to be happy with the status quo. He is always trying new ideas.

I noticed that Bryan had been adding aluminum rails to the front of Cerus stocks to lower the center of gravity and improve tracking. I asked him to modify my stock and fit it with the new forearm rails, shown in the photo below. I sent him a Panda F-Class action with a +20 MOA Picatinny rail. Bryan did all the stock work and fitted the action, rails, and RAD recoil pad. Everything turned out flawless.

The barrel is a Blake Machine 1:8″-twist finished at 32 inches. It was fitted to my action by Dale Woolum of Woolum Accuracy. Dale chambers all my barrels on all my rifles. Dale also threaded the barrel for a Woolum Accuracy tuner. This has proven to be a valuable tool in my load development. On this build, I am trying a Bix’N Andy trigger for the first time.

The 284 Shehane has a proven record of accomplishments and that is why I have chosen it. I use Lapua brass (6.5-284 necked-up), CCI BR-2 primers, Hodgdon H4350 powder, and Berger 184gr bullets. All these components have been a successful combination that has worked flawlessly in my other rifle.

.284 Shehane Load Development
Load development for me starts with each new barrel. I screw on the new barrel, fire 25 rounds of whatever I have left over and then clean it. I push out to 600 yds and do a ladder test in round-robin format. I start 0.6 grains lower than my last charge that worked. I work up from that reduced charge weight in increments of 0.3 grains. The paper tells the rest of the story. Once I get something that works well at 600 yards I go back in work around that by 0.1 grains. After that I play a little with seating depth and look for a change. I will occasionally mess with the tuner and tighten things up if possible.

About the Patriotic Paint Job
So I had the idea of painting the stock because there are so many wood stocks with clear coat these days. Unless you really get some exotic woods they all seem to blend together. I have nothing against clear-coated wood, but I wanted something different, as this was my first all-wood rifle. (For short-range benchrest, I was shooting a Bob Scoville carbon stock and Terry Leonard laminate).

We started with all white on the stock and came up with the idea of an American Flag on the buttstock. I was thinking of ribbons on the front in red and blue but we could not get the layout right. Then the idea of “We the People” popped into the head. My painter said “awesome!” and he was able to airbrush the stock with a little yellow and brown to give it that vintage paper look.

The front rest is a SEB Max (see above). I chose the Max because I was shooting Group Benchrest first then made the transition to F-Class. This rest proves to be versatile in all my shooting — Short- and Long-Range Benchrest AND F-Class. The rear bag is a Edgewood EDGEbag Gator. The gun gets transported in a Pelican Hard case when I travel. Locally, I use a Champions Choice soft bag.

Jason Jumped to Open Class after Starting with F-TR
This “We the People” rifle will be one of my primary rifles for F-Open competition. I will run it through its paces shortly and see how well it does. I have high hopes of it being an great gun. I shoot primarily local and regional matches — Colorado, Wyoming, and possibly Nebraska this summer. I will travel to the F-Class Nationals in Raton as well. I used to shoot F-TR before this and made the transition to Open last season. This is my second season shooting F-Open. 2018 was my first National event and was a learning experience for me. But I was hooked after that match.

Tips for F-Class Competitors
Get some good equipment and eliminate having issues that can be caused by budget builds. It’s OK to be frugal, but sometimes cutting corners will cause you more problems and have you chasing your tail. If you’re looking for the “recipe for success”, get a good action plus a top-tier barrel and great glass.

The .284 Shehane — Accurate and Forgiving Wildcat
The 284 Shehane is amazing, very forgiving and not temperamental. I choose this because I really did not know otherwise and was steered to the Shehane by a friend. Its proven track record helped as well. Straight .284 or Shehane — you cannot go wrong. I run a 184gr Berger at about 2850 FPS and get great brass life in my other rifles. I usually start to consider tossing the brass around 15 firings. Primer pockets start to get a little looser and the brass seems to need more sizing than the newer brass with less firings.

Yes, folks, it’s officially summer now. This year’s Summer Solstice, considered the official start of summer (and the longest day of the year), happened Sunday, June 21, at 1:24 AM Pacific Daylight Time (PDT).

We hope you have fun this summer with friends and family. To help ensure those summer adventures remain safe and trouble-free, the CTD Shooters’ Log has prepared a helpful Essential Summer Survival Guide. This is worth reading before you venture away from civilization.

The CMP Rimfire Sporter discipline is for smallbore rifles that weigh 7 1/2 pounds or less with sights. Firing is done at 25 and 50 yards in prone, sitting, and standing positions, in slow and rapid-fire modes. The CMP has a special smart-phone App that helps speed up scoring. Rimfire Sporter matches are held throughout the country in connection with the CMP’s Travel Games.

And each summer, the major National Rimfire Sporter Match attracts hundreds of shooters to the shore of Lake Erie at Camp Perry. This year’s Rimfire Sporter Match at Camp Perry will be held on Saturday, August 1st, 2026, with check-in/clinic on Friday, July 31, 2026. The CMP National Rimfire Sporter Rifle Match offers shooters a recreation-oriented competition where they use affordable, smallbore sporter rifles with either scopes or iron sights. All you need are a .22 LR rifle, sling, and ammo.

FREE GUIDE: 48-Page CMP Guide to Rimfire Sporter Shooting »

Rifles may be manually operated or semi-automatic, in three classes: the standard “O Class” for open-sighted rifles, “T-Class” for telescope-sighted rifles, and the “Tactical Rimfire” Class. Firing is done at 50 and 25 yards on a target with a 1.78″ ten-ring. The target is simple enough for a beginner to hit, yet challenging enough that only one competitor in the history of the match has ever fired a perfect 600 score.

Rimfire Sporter Course of Fire

At the Rimfire Sporter Match, competitors complete slow fire prone, rapid fire prone, slow fire sitting or kneeling, rapid fire sitting or kneeling, slow fire standing, and rapid fire standing shot sequences.

What is Required for the Camp Perry Rimfire Sporter Match

Competitors need to bring their own .22 cal. Rimfire rifle(s) and ammunition. Special target shooting equipment, shooting jackets, or shooting gloves are not permitted, but you can bring a spotting scope and ground cloth or shooting mat. The firing points have grass (sometimes a bit wet with rain). Competitors are strongly urged to wear hearing and eye protection. Assistance for disabled competitors is provided.

A free Shooters’ Clinic is usually held in connection with the Rimfire Sport match at Camp Perry. The Clinic covers Rimfire Sporter rules, safety instructions, course of fire, and competition procedures. Shooters who have not previously attended a CMP Rimfire Sporter Match are strongly encouraged to attend.

This week the U.S. Supreme Court issued an important decision on a gun rights case challenging restrictive laws in Hawaii. In Wolford v. Lopez, the Supreme Court held that a Hawaiian law prohibiting concealed carry on private property (and business locations) violated the Second Amendment of the U.S. Constitution.

Fox News explained: “The U.S. Supreme Court ruled against Hawaii on Thursday (6/25/26), handing concealed-carry permit holders a major victory in a 6-3 decision. The Supreme Court sided with the plaintiff in Wolford v. Lopez, who contested Hawaii’s state law requiring a property owner’s explicit permission to allow lawful gun owners to bring firearms into public businesses.” This affected the ability of residents to carry licensed handguns into stores, hotels, and other venues.

LINKS to Reports: FOX News | N.Y. Times | MSN.com | CBS News | ABC News

“Hawaii’s law at issue here violates the constitutional right to keep and bear arms,” Justice Samuel Alito wrote. “This regime hobbles what the Second Amendment protects: the right of Americans to carry arms for self-defense as they go about their daily lives.”

The ruling reverses a decision by the U.S. Court of Appeals for the Ninth Circuit, which had upheld Hawaii’s restrictions after the state enacted them in response to the Supreme Court’s 2022 Bruen decision.

Here is an analysis of the case from the Second Amendment Foundation (SAF):

For the second week in a row, the U.S. Supreme Court has handed a victory to gun owners after striking down Hawaii’s so-called “Vampire Rule” in Wolford v Lopez.

Last year, the Second Amendment Foundation (SAF) filed an amicus brief urging the Supreme Court to strike the law down. The Hawaii law, similar to statutes found in California, New York and other states, bans carry of firearms on property open to the public — grocery stores, restaurants, gas stations and more — unless the owner posts a sign stating that carry is allowed on the premises. Prior laws permitted lawful carry in businesses open to the public unless the owner affirmatively requested that guns not be carried. The flipping of the default situation – from allowing guns unless denied, to banning all guns unless invited – created a de facto public carry ban that … the Supreme Court has held to violate the Second Amendment.

“Our stance is that one of the most fundamental underlying principles of the Second Amendment is the right to carry in public for self-defense,” said SAF Exec. Director Adam Kraut. “If a business does not want you to carry a firearm on the premises, the burden should be on the proprietor, not the private citizen, which would be in line with the ‘no soliciting’ or ‘no shoes, no shirt, no service’ signs we’re all familiar with. Today the Supreme Court told Hawaii that such transparent attempts at banning constitutionally protected conduct will not be tolerated.”

“The Supreme Court rightfully overturned the Ninth Circuit’s ruling in Wolford and now the Second Amendment rights of Hawaii’s residents are one step closer to being fully restored,” said SAF Exec. V.P. Alan M. Gottlieb. “This law was nothing more than a thinly veiled attempt to disarm peaceable citizens, and we’re grateful the Supreme Court saw through the ruse. With this precedent-setting ruling in hand, other states that have similar laws in place should be on notice – SAF is coming after you[.]”
