CONGRESS MAKES BIPARTISAN REBUKE of PRESIDENT BIDEN’S HUNTER EDUCATION ATTACKS
The National Shooting Sports Foundation (NSSF) praised the U.S. Congress for the swift and decisive vote to rebuke President Joe Biden’s unprecedented move to defund scholastic hunter education and archery programs available for youths. The U.S. House of Representatives approved H.R. 5110, the Protecting Hunting Heritage and Education Act, in a 424-1 vote and the U.S. Senate hot-lined the legislation, passing it by unanimous consent. The legislation, introduced by U.S. Reps. Mark Green (R-TN) and Richard Hudson (R-NC) is now headed to President Biden’s desk for consideration.
The White House has not signaled whether the president will sign or veto the legislation. However, Congress approved the bill in a rare and overwhelming veto-proof majority. Should the president veto the legislation, Congress could override the president’s veto and enact the law.
“This is a tremendous victory for true and proven firearm safety, as well as a reminder of how Congress can unite to protect the American public from special-interest driven agendas,” said Lawrence G. Keane, NSSF Senior Vice President and General Counsel. “This should have never been an issue. Congress never wrote into the Bipartisan Safer Communities Act that hunter education and archery programs were ineligible for funding. That was a unilateral decision to appease gun control and anti-hunting special interests. It was an unforced error that the Biden administration refused to acknowledge. Congress, as the representatives of the people, has spoken and spoken loudly and clearly.”
The Biden administration wrongly claimed the Bipartisan Safer Communities Act (BSCA) forbid the funding of school-based hunter education and archery programs. That was never in the language or intent of the law. Congress appealed to the Biden administration to reverse course in several bipartisan and bicameral letters. Biden could have resolved the issue by simply reversing the policy to deny funds for the essential scholastic programs by ending the policy put into place by Education Secretary Miguel Cardona.
Congress acted when administration officials refused. Congress passed the Protecting Hunting Heritage and Education Act less than two months after it was introduced. NSSF is deeply grateful to Congressmen Green and Hudson for their leadership to restore hunter education and archery funding for schools, as well as for Congress for setting aside partisan politics to represent the interests of all Americans and true and proven firearm safety programs.

Gun Owners of America (GOA) and the Gun Owners Foundation (GOF) teamed up with Gun Owners of California (GOC) to file suit challenging portions of SB 2, a bill that anti-gun Governor Gavin Newsom signed into law this week. This unconstitutional legislation was passed in response to the Bruen decision (which ended the state’s draconian “may-issue” policy). As signed by Newsom, California SB 2 will:
— Create vast, restricted “sensitive locations” where concealed carrying would be prohibited, including all private property unless expressly permitted by the owner;
— Require 16 hours of training;
— Significantly increase the costs associated with securing a permit.
This lawsuit challenging SB 2 was filed in the U.S. District Court (Central District South) in Calfornia. The action, entitled May et al v. Bonta specifically goes after the “sensitive locations” provision of the law. Several other anti-gun states have enacted similar unconstitutional legislation in response to the Bruen decision, and GOA and GOF are a part of litigation in several of these cases.

Erich Pratt, GOA’s Senior Vice President, issued the following statement:
“This is just the latest assault on our rights in California. Just as concerning, Governor Gavin Newsom has already made his anti-gun intentions quite clear: he wants to effectively repeal the Second Amendment. Sadly, his acknowledgment that doing so would be the only way to enact more gun control did not dissuade him from violating his oath when he signed this law into effect, but we are fully prepared to fight back.”
Sam Paredes, on behalf of the board for GOF and in his role as the Executive Director of Gun Owners of California, added:
“Pro-gun groups in California have had success when pushing back on legislation like this –just look at our victory last week against the state’s magazine ban. And just like in that case, we are confident SB 2 will be overturned. I’ve been warning governors and legislatures across the country since the Bruen decision that these ‘response bills’ will not stand, but unfortunately, many have still been pushed through. That won’t stop us however – states should fall in line, or we will make them.”
Over 22 million carry permits have been issued in the United States according to a recent study. Overall 8.5% of American adults now have carry permits. Along with CCW permit holders, millions of other gun owners may carry defensive pistols in “open carry” states. Carrying a defensive pistol is a big responsibility. That’s why all those who carry handguns for self-protection should definitely practice regularly. For many, pistol practice is an indoor experience. Indoor ranges are most convenient for those who live near urban centers, where the biggest threats to public safety currently exist. This article covers indoor firearms training and the proper procedures you should follow at indoor ranges.
This Video Covers Basic Gun Range Safety Rules and Etiquette
FIVE IMPORTANT SAFETY PROCEDURES for Indoor Ranges
1. Follow the Three Fundamental Rules for Safe Gun Handling
ALWAYS keep the gun pointed in a safe direction. ALWAYS keep your finger off the trigger until ready to shoot. ALWAYS keep the gun unloaded until ready to use.
2. Follow ALL Range Officer Instructions
ROs are the first and final authority on any range and their decisions are generally final. Arguing with a Range Officer may just get you thrown out.
3. Don’t Bother Others or Touch Their Guns
Respect other shooters’ privacy unless a safety issue arises. Do NOT engage other shooters to correct a perceived safety violation unless absolutely necessary – inform the RO instead. NEVER handle or touch another shooter’s firearm without their permission!
4. Know Your Range’s Rules
Review and understand any and all range rules and requirements/expectations. For example, what is the range’s maximum rate of fire? Are you allowed to collect your brass?
5. Know What To Do During a Cease Fire
IMMEDIATELY set down your firearm, pointed downrange, and STEP AWAY from the shooting booth (or bench). Range Officers do not want shooters trying to “secure/unload” their firearms in a cease fire situation — they want the shooters separated from their guns instantly.
Double-Up on Hearing Protection When Shooting Indoors
Howard Leight states that Impact Pro muffs are “designed for handgun and pistol shooters looking for high NRR … for indoor ranges, covered ranges or other extremely loud shooting environments.”
When shooting indoors we recommend quality muffs with earplugs underneath, offering double protection. When inside an enclosed range, with other shooters blasting away right next to you, you really need effective hearing protection. But you also need to hear range commands and be able to communicate. That’s why we recommend electronic muffs with quality plugs underneath. We recommend the NRR 33 Howard Leight Max-1 Plugs. These tapered plugs are comfortable, easy to insert, and have a flared end for better sound seal.
On top of those plugs, run high-quality muffs. For indoor ranges where sound levels can be extremely high, we recommend Howard Leight Impact Pro Muffs. These offer an impressive 30 dB Noise Reduction Rating (NRR) and the effective noise reduction can be improved by 4 decibels or more by running plugs as well.* These muffs are pretty comfortable and offer Headphone Functionality so you can connect to your smartphone, MP3 player, or other audio device. These muffs are a good value, an Amazon’s Choice for $64.97.
* Four decibels may not sound like much, but remember the decibel measurement system is logarithmic, so four decibels is VERY significant. We have discussed the merits of “doubling up” hearing protection with Ph.D. sound engineers. They told us that a combination of muffs and plugs could reduce effective noise levels by up to five decibels compared to plugs alone. In addition, good muffs will block bone conduction sound energy better than plugs alone.
Many short-range Benchresters have thought about converting their 6 PPC to shoot a 30BR for score matches, or a Dasher for mid-range (or even 1000-yard) games. That way you have a rifle that does double duty, giving you the most bang for your buck. Though an action with a PPC bolt won’t normally work with 30BR/6BR/Dasher cases with their larger .308-class rim (0.4728″ diameter), there is a pretty easy solution that allows you to cycle these bigger cartridges with a 6PPC-style bolt (designed to fit .220 Russian rims).
“Rebating case rims … lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle.” — Butch Lambert
Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
Rebate Your 30 BR Rims
To convert a PPC-boltface action to shoot bigger cases you can spend a ton of money to buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.”
At right is the lathe form tool Butch uses to rebate the case rims.
They say that a man can never have too much money or too much time. Darrell Jones would add that a man can never have too many BR-based rifles. Darrell had a fleet of BRs, in 22 BR, 6mm BR, 6.5 BR, 7 BR, and 30 BR. But he was intrigued by the potential of a rifle in the .257 caliber. Could it shoot as well as a 6mm BR? Could it challenge the more popular calibers in the highly competitive 600-yard benchrest game? Through careful research and component selection, Darrell created a 25 BR rifle that proves the viability of the 25 BR as a competition round. Pushing 115gr high-BC Berger bullets at 2837 fps, Darrell’s 25 BR “Peppermint” won first place in its very first match.
The Barely Bigger BR — Exploring the .25 Caliber Option
Rifle Report by Darrell Jones
I decided to build a 25 BR after several weeks of deliberation and ruling out a .257 Ackley Improved. Part of my dilemma was that I wanted to shoot F-Class competition at 600 yards, and I was unsure about the accuracy potential of the 25 BR. However, I currently have several BRs chambered in 22 BR, 6BR, 6.5 BR, 7 BR, and 30 BR and they all shoot exceptionally well at 600 yards. This lead me to believe a 25 BR should deliver fine accuracy, just like its other BR siblings. Why wouldn’t a 25 BR shoot accurately provided that I built it with the right components? The feasibility saga began. I began searching diligently for custom 25-caliber bullets. Unfortunately, there are not many 25-caliber custom bullet makers. I actually found only two custom bulletsmiths who produce the 25s. I did look at Fowlers and then looked at Bergers. Both Jeff Fowler and Berger made 110-grain flat-base bullets when I was looking. [Editor — this 110gr bullet is no longer listed by Berger]. The Berger 110gr FB bullets (.414 ballistic coefficient) shot very well out of my 12-twist 25-06 Ackley. However, I wanted to shoot a heavier bullet if possible. Berger makes a 25-caliber 115gr VLD boat-tail with a high ballistic coefficient. This needs a 10-twist barrel.
Panda Action, McMillan Stock, Weaver T-36
As you can see, I went with a Panda polished action and a weighted McMillan BR stock painted metallic silver with red candy cane stripes thus the name “Peppermint”. This gun actually does double duty now as a 25 BR and 6 PPC switch barrel. When I want to run the gun as a 6 PPC for short range, I simply screw on the PPC barrel, then swap in a bolt (fitting the PPC bolt face) from another Panda action I own. That’s one advantage of owning custom Kelbly actions! Don’t even think about exchanging bolts between factory guns. Kelbly rings and a Weaver T-36 fixed-power scope handle the optical duties while a Jewell trigger set at one ounce takes care of the firing mechanism.
Chambering for the .25 Caliber BR Wildcat
I wanted a chamber that would let me shoot both the 110s and the 115s. I took some time surfing the net looking for rental reamers that had suitable throat dimensions. I found that Elk Ridge Reamer Rentals had a 25 BR pilot reamer available. I called and Elk Ridge faxed me a reamer diagram that indicated it was designed to tight SAMMI specs. I asked how often was the reamer used and was told “not very often”.
I did want a minimum no-turn neck optimized for Lapua brass. The drawing indicated that the reamer would cut a .281″ neck and a throat of 1.0315″. This was very close to ideal, though I did have to turn two thousandths off the necks of Lapua 6BR brass after I necked it up. I resized using a .277″ bushing and the loaded rounds came out to be .279″. Realizing that this was in the ball park, I decided to go with the Elk Ridge Reamer and build a 25 BR that could shoot 110gr or 115gr bullets. Now the question was where to get a match-grade 25-caliber barrel. I called quite a few of the custom barrel-makers, including BlackStar Barrels in Texas (no longer operating). I have had wonderful success with the BlackStar barrel on my 6BR “Chantilly” — it delivered great accuracy and impressive velocities. Since the 25 BR was so similar, I went with another BlackStar. I ordered a 10-twist, 6-groove, 1.250″-diameter straight-contour tube.
After chambering, the barrel finished at 1.245″ diameter and 27.5″ inches with an 11° crown. I actually had the throat lengthened to accept both Berger 110gr and 115gr bullets. The bases of the FB 110-grainers sit flush with the neck-shoulder junction, when they are seated .010″ into the lands. With the longer 115gr VLDs, the bottom of the bearing surface (i.e. start of boat-tail) is just about even with the neck-shoulder junction.
Accurate Load Development
The barrel broke in easily with just 10 shots, using a “shoot one and clean” process. The load I started with was 31.5 grains of Varget with CCI 450 primers. The Berger 110s and Berger 115s had the same Point of Impact (POI) at 100 yards. However, the 115s impacted two inches higher at 600 yards with the same load. That shows the benefits of a higher BC. Pushed by the CCI 450s and 31.5 grains of Varget, the 115-grainers were running about 2837 FPS. I boosted the load up to 32.0 grains but I noticed primer cratering, so I backed off, settling on 31.5 grains for the 115gr Berger VLD.
Peppermint Wins at 600 Yards
For her debut in competition, I took “Peppermint” to our local 600 yard F-class match. Shooting the Berger 115s with 31.5 grains Varget, she won with a perfect score of 200 with 14 Xs. At my club, we use a SR3 target. The X-Ring measures 3″ in diameter and the 10-Ring measures 7″. At the match there were some very good shooters with top-flight custom rifles in accurate calibers such as 6.5-284 and 22 Dasher. I was very fortunate to come out on top, but I give the credit to Peppermint’s good bench manners and outstanding accuracy.
As you can see from the target, “Peppermint” is a very accurate rifle that has proven herself in competition. It takes a good gun to finish “on top” in her very first match. So far, I’m very happy with the project, and more than satisfied with the accuracy of the 25 BR. This is definitely a worthy cartridge for Egg Shoots, 500m varmint matches, and the 600-yard F-Class game.

Comparing the BR-Based Variants
Now that I have several calibers in the BR cartridge family, (22 BR, 6mm BR, 6.5 BR, 7 BR, and a 30 BR), it is my humble opinion that they each have their own place. A varmint hunter’s dream, the 22 BR can push a bullet faster and more accurately than the 22-250. With an 8-Twist barrel, the 22 BR can send an 80gr SMK to 600 yards with extreme accuracy.
The 6 BR can do it all. The 6mm caliber offers a wide variety of quality bullets suitable for any shooting situation. All the major custom barrel makers produce outstanding 6mm barrels in a full range of twists. Moreover, since the 6 BR cartridge is so popular, there is a great store of knowledge about reloading for the 6 BR. It is easy to find a load that will shoot superbly in any bullet weight.
The 25 BR has proved to be easily tuneable, proficient and not fickle. You can obtain extreme accuracy without great effort in load development. The 115gr Berger offers a good high-BC projectile for this caliber, making the 25 BR a viable alternative to the 6 BR. As I’ve shown, it is competitive with a 6 BR in head to head competition.
Compared to the 25 BR, the 6.5 BR has a small edge in ballistics. However, there are not many light bullet choices available, especially from custom makers. The 123gr Lapua Scenar is an excellent bullet with a .547 stated BC, but it may be a bit heavy for the case capacity.
The 7 BR was designed for silhouette shooting, and it excels at that task. The 7 BR can push a 130 grain bullet fast enough to knock over the steel silhouettes at 500 meters with real consistency.
The 30 BR is nothing less than outstanding. The 30 BR is now the dominant cartridge on the benchrest Score-shooting circuit. It is also highly accurate for group shooting at 200 yards and very capable of winning a 600-yard F-Class match. Barrel life of over 6,000 rounds is realistic.
I like all the “flavors” of BR derived from the 6mm BR Norma case. However, if I could only have one BR in my safe, give me my 8-Twist, 6 BR “Chantilly” and I will be a happy camper. The final point I would make is if a cartridge is stamped BR on the case, it will shoot extremely accurately if you can.
September 23, 2023, was National Hunting and Fishing Day (NHFD). We’re proud to recognize how important hunting is for millions of Americans — as a source of food for families and as an important connection with nature and the outdoors. The NFHD website has helpful resources for hunters, and in this article we provide links for Where to Hunt, How to get Hunting Licenses, and Hunter Education.
NHFD was first established by President Nixon in 1972. According to NationalToday.com, NHFD’s “roots go back more than 100 years to President Theodore Roosevelt, who introduced the first laws regulating the hunting of wildlife in the United States.”
This month we hope some of our readers can take new shooters afield and introduce them to hunting. Many hunters receive their first introduction to hunting from family or friends as a tradition passed down from generation to generation. There are over 9.2 million hunters in the United States.
To have a successful hunt you must first get to areas where game thrives. Finding the right places to hunt is essential. The NSSF offers a nationwide Where-to-Hunt database of hunting areas. You can click on a particular state, then specify the specicies you wish to hunt. This is a very useful resource.
In most states, when hunting game animals, you’ll need a hunting license and/or zone permit. The Federal Fish & Wildlife Service has state-by-state listing for hunting licenses on FWS.gov. Click the box below to learn how to get hunting licenses in your region.
For all hunters, whether they have mentors to guide them or not, the most important first step into the woods begins with a state-certified hunter education course. Click the box below to see hunting education opportunities around the nation.

Here are two different bullet types, seated to the same CBTO length, but different COAL. Note the shiny scratches on the bullets made by the comparator tool which indicates a point on the bullet ogive near where the ogive will engage the rifling.
Effects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 2 by Bryan Litz forBerger Bullets. Part One of this series focused on the importance of COAL in terms of SAAMI standards, magazine lengths, seating depths, and pressure levels. Another measure of length for loaded ammunition is highly important to precision, namely Cartridge Base to Bullet Ogive Length (CBTO).
Figure 2. Chamber throat geometry showing the bullet jump to the rifling or lands.
Look at Figure 2. Suppose the bullet was seated out of the case to the point where the base of the bullet’s nose (ogive) just contacted the beginning of the riflings (the lands) when the bolt was closed. This bullet seating configuration is referred to as touching the lands, or touching the riflings and is a very important measurement to understand for precision hand-loading. Due to the complex dynamics of internal ballistics which happen in the blink of an eye, the distance a bullet moves out of the case before it engages the riflings is highly critical to precision potential. Therefore, in order to systematically optimize the precision of his handloads, it’s critically important that the precision hand-loader understands how to alter bullet seating depth in relation to the barrel rifling. Part of the required knowledge is understanding how to accurately and repeatably measure the Cartridge Base To Ogive (CBTO) dimension. This is explained in the FULL ARTICLE.
Bryan Litz offers an extended discussion on how to measure CBTO using different tools and methods, including the Hornady OAL gauge. You can read this discussion in the full article found on the Berger Bullets website. CLICK HERE to Read Full Article.
Why Not Use CBTO as a SAAMI Standard?
If CBTO is so important to rifle accuracy, you might ask, “Why is it not listed as the SAAMI spec standard in addition to COAL?” There is one primary reason why it is not listed in the standard. This is the lack of uniformity in bullet nose shapes and measuring devices used to determine CBTO.
Benefits of Having a Uniform CBTO
There is another aspect to knowing your CBTO when checking your COAL as it pertains to performance. With good bullets, tooling, and carefully-prepared cases you can easily achieve a CBTO that varies less than +/- .001″ but your COAL can vary as much as .025″ extreme spread (or more with other brands). This is not necessarily bad and it is much better than the other way around. If you have a CBTO dimension that varies but your COAL dimension is tight (within +/- .002″) then it is most likely that your bullet is bottoming out inside the seater cone on the bullet tip. This is very bad and is to be avoided. It is normal for bullets to have precisely the same nose shape and it is also normal for these same bullets to have nose lengths that can vary as much as .025″.
Summary of Cartridge Base To Ogive (CBTO) Discussion
Here are four important considerations regarding bullet seating depth as it relates to CBTO:
1. CBTO is a critical measurement to understand for handloaders because it’s directly related to precision potential, and you control it by simply setting bullet seating depth.
2. Tools and methods for measuring CBTO vary. Most of the measurement techniques have pitfalls (which may give rise to inconsistent results) that you should understand before starting out.
3. A CBTO that produces the best precision in your rifle may not produce the best precision in someone else’s rifle. Even if you have the same rifle, same bullets, same model of comparator gauges, etc. It’s possible that the gauges are not actually the same, and measurements from one don’t translate to the same dimension for another.
4. Once you find the CBTO that produces the best precision in your rifle, it’s important to allow minimal variation in that dimension when producing quality handloads. This is achieved by using quality bullets, tooling, and properly preparing case mouths and necks for consistent seating.
If you don’t match your ammo to your chamber, bad things can happen, that’s for sure. A while back, Forum member BigBlack had an experience at the gun range that reminds us of the importance of safety when shooting. He encountered evidence that someone had fired the wrong cartridge in a 7mm WSM rifle. The problem is more common than you may think. This Editor has personally seen novices try to shoot 9mm ammo in 40 S&W pistols. BigBlack’s story is along those lines, though the results were much more dramatic. It’s too bad a knowledgeable shooter was not nearby to “intervene” before this fellow chambered the wrong ammo.
7mm-08 is Not the Same as a 7mm WSM
BigBlack writes: “I know this has probably been replayed a thousand times but I feel we can never be reminded enough about safety. This weekend at the range I found a ruptured case on the ground. My immediate thoughts were that it was a hot load, but the neck area was begging for me to take a closer look, so I did. I took home the exploded case and rummaged through my old cases until I found a close match. From my investigative work it appears someone shot a 7mm-08 in a 7mm WSM. Take a look. In the above photo I’ve put together a 7mm WSM case (top), the ruptured case (middle), and a 7mm-08 case (bottom).”
The photo reveals what probably happened to the 7mm-08 case. The shoulder moved forward to match the 7mm WSM profile. The sidewalls of the case expanded outward in the much larger 7mm WSM chamber until they lacked the strength to contain the charge, and then the case sides ruptured catastrophically. A blow-out of this kind can be very dangerous, as the expanding gasses may not be completely contained within the action.
Can’t Happen to You? Think Again.
This kind of mistake — chambering the wrong cartridge — can happen to any shooter who is distracted, who places even a single wrong round in an ammo box, or who has two types of ammo on the bench. One of our Forum members was testing two different rifles recently and he picked up the wrong cartridge from the bench. As a result, he fired a .30-06 round in a .300 Win Mag chamber, and the case blew out. Here is his story:
“I took two of my hunting rifles I have not used for over 25 years to the range yesterday to get new scopes on paper, a .30-06 and .300 Win Mag. I had four boxes of old Winchester factory ammo (two of each cartridge), which had near identical appearances. I accidentally chambered a .30-06 round in the Sako .300 Win Mag rifle. It sprayed powder on my face and cracked the stock at the pistol grip. If I had not been wearing safety glasses I might be blind right now.
You should always wear protective eyewear, EVERY time you shoot.
“I feel lucky and am very thankful for being OK — other than my face looks funny right now. I am also grateful for learning a valuable lesson. I will never put two different cartridges on the bench at the same time again.”
“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag….
Ruprecht Nennstiel, a forensic ballistics expert from Wiesbaden, Germany, has authored a great resource about bullet behavior in flight. Nennstiel’s comprehensive article, How Do Bullets Fly, explains all the forces which affect bullet flight including gravity, wind, gyroscopic effects, aerodynamic drag, and lift. Nennstiel even explains the rather arcane Magnus Force and Coriolis Effect which come into play at long ranges. Nennstiel’s remarkable resource contains many useful illustrations plus new experimental observations of bullets fired from small arms, both at short and at long ranges.
Shadowgraph of .308 Winchester Bullet
A convenient index is provided so you can study each particular force in sequence. Writing with clear, precise prose, Nennstiel explains each key factor that affects external ballistics. For starters, we all know that bullets spin when launched from a rifled barrel. But Nennstiel explains in greater detail how this spinning creates gyroscopic stability:
“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag, the plane, formed by the velocity vector ‘v’ and the longitudinal axis of the bullet. In the absence of spin, the yaw angle ‘δ’ would grow and the bullet would tumble.
If the bullet has sufficient spin, saying if it rotates fast enough about its axis of form, the gyroscopic effect takes place: the bullet’s longitudinal axis moves into the direction of the overturning moment, perpendicular to the plane of drag. This axis shift however alters the plane of drag, which then rotates about the velocity vector. This movement is called precession or slow mode oscillation.”
Raise Your Ballistic IQ
Though comprehensible to the average reader with some grounding in basic physics, Nennstiel’s work is really the equivalent of a Ph.D thesis in external ballistics. You could easily spend hours reading (and re-reading) all the primary material as well as the detailed FAQ section. But we think it’s worth plowing into How Do Bullets Fly from start to finish. We suggest you bookmark the page for future reference. You can also download the complete article for future reference and offline reading.
Everytown Comes Out from Behind the Curtain
By Larry Keane, NSSF Senior V.P. and General Counsel
For years, gun control organizations have been seeking to dismantle the bipartisan Protection of Lawful Commerce in Arms Act (PLCAA). That’s the crucial federal law shielding firearm manufacturers and sellers from frivolous lawsuits designed to bankrupt law-abiding businesses by blaming them for the criminal misuse of lawfully-sold firearms … and impose gun control through court-ordered settlements. It is what former Clinton Secretary of Labor Robert Reich dubbed “regulation through litigation”.
Gun control advocates have unsuccessfully urged Congress to repeal the law, falsely claiming it provides total immunity from all lawsuits — a falsehood regularly repeated by President Joe Biden even though the media has fact-checked him and said it is not true. In court, these groups have unsuccessfully challenged the PLCAA’s constitutionality. Attorney General Merrick Garland testified before Congress that the PLCAA was Constitutionally-sound, despite the contrary rhetoric coming from The White House and the gun ban lobby. They continue to ask courts to misapply the law’s exceptions (disproving the total immunity claim). All these efforts are designed to open up a new floodgate of frivolous litigation against the industry not seen since the late 1990s and early 2000s. It was that litigation which the bipartisan PLCAA prevents.
Now, the enemies of the Second Amendment have opened up a new line of attack on the PLCAA. Surreptitiously led by the Bloomberg-funded Everytown for Gun Safety, they have convinced a few “Blue” antigun legislatures to pass unconstitutional “public nuisance” (anti-PLCAA) statutes. These statutes attempt an end run around the PLCAA to set the table for a renaissance of reckless lawsuits against members of the industry. NSSF is challenging the Everytown-backed laws in New York, New Jersey, Delaware, California, Illinois, Washington and Hawaii.

Everytown’s masquerade as a champion of responsible firearm regulation is a sham. Their actions speak louder than their hollow words. By actively participating in “public nuisance” lawsuits and championing laws like Hawaii’s HB 426, Everytown lays plain its intention to undermine the PLCAA and smother the firearm industry with irrational restrictions that only erode the Second Amendment rights of Americans and do nothing to make communities safer. Their track record of manipulating tragic events for their own political gain is morally reprehensible.
I did want a minimum no-turn neck optimized for Lapua brass. The drawing indicated that the reamer would cut a .281″ neck and a throat of 1.0315″. This was very close to ideal, though I did have to turn two thousandths off the necks of Lapua 6BR brass after I necked it up. I resized using a .277″ bushing and the loaded rounds came out to be .279″. Realizing that this was in the ball park, I decided to go with the Elk Ridge Reamer and build a 25 BR that could shoot 110gr or 115gr bullets. Now the question was where to get a match-grade 25-caliber barrel. I called quite a few of the custom barrel-makers, including BlackStar Barrels in Texas (no longer operating). I have had wonderful success with the BlackStar barrel on my 6BR “Chantilly” — it delivered great accuracy and impressive velocities. Since the 25 BR was so similar, I went with another BlackStar. I ordered a 10-twist, 6-groove, 1.250″-diameter straight-contour tube.
After chambering, the barrel finished at 1.245″ diameter and 27.5″ inches with an 11° crown. I actually had the throat lengthened to accept both Berger 110gr and 115gr bullets. The bases of the FB 110-grainers sit flush with the neck-shoulder junction, when they are seated .010″ into the lands. With the longer 115gr VLDs, the bottom of the bearing surface (i.e. start of boat-tail) is just about even with the neck-shoulder junction.
For her debut in competition, I took “Peppermint” to our local 600 yard F-class match. Shooting the Berger 115s with 31.5 grains Varget, she won with a perfect score of 200 with 14 Xs. At my club, we use a SR3 target. The X-Ring measures 3″ in diameter and the 10-Ring measures 7″. At the match there were some very good shooters with top-flight custom rifles in accurate calibers such as 6.5-284 and 22 Dasher. I was very fortunate to come out on top, but I give the credit to Peppermint’s good bench manners and outstanding accuracy.
Now that I have several calibers in the BR cartridge family, (22 BR, 6mm BR, 6.5 BR, 7 BR, and a 30 BR), it is my humble opinion that they each have their own place. A varmint hunter’s dream, the 22 BR can push a bullet faster and more accurately than the 22-250. With an 8-Twist barrel, the 22 BR can send an 80gr SMK to 600 yards with extreme accuracy.
