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.
One of our readers asked “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, 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′ ASL or less. I’ll need about 29-30 MOA to get from 100 yard to 1000 yards with a Berger 155gr VLD @ 2960fps. By contrast, in Raton, NM, located at 6600′ ASL, 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.”
Sierra Bullets has recently released load data for the 6mm Creedmoor cartridge, a necked-down version of the 6.5 Creedmoor, a popular PRS, tactical, and hunting cartridge. Sierra has released very comprehensive 6mm Creedmoor load data, covering fifteen (15) different bullets from 55 to 110 grains. NOTE: Hornady-brand brass was used for Sierra’s 6mm Creedmoor load tests, not the newer, stronger Lapua 6.5 CM brass with small primer pockets. Hand-loaders using Lapua 6.5 Creedmoor brass necked to 6mm may have to adjust their loads.
Sierra writes: “As soon as the 6.5 Creedmoor was released in 2007, a 6mm version was being envisioned. After the 6mm Creedmoor demonstrated its worth at 1000 yards it began to catch the attention of Precision Rifle Series (PRS) competitors. The 6mm/6.5 Creedmoor is a great fit for those looking for an AR platform-friendly cartridge. It delivers velocities very similar to the .243 Win and yet fits the AR10 magazine length[.] The 30-degree shoulder makes this a very efficient case and helps prolong case life as well. The 6mm/6.5 Creedmoor works well with powders such as H4350, RE-17, and Ramshot Hunter for heavier long-range bullet weights. Slightly faster powders such as RE-15, Win 760, and Vihtavuori N540 work well with lighter weight bullets.”
Sierra Bullets Tested for 6mm Creedmoor Load Data
55gr BlitzKing (#1502)
60gr HP (#1500)
70gr HPBT (#1505)
70gr BlitzKing (#1507)
75gr HP (#1510)
In developing its 6mm Creedmoor load data, Sierra tested a very wide selection of propellants, two dozen overall. For the smaller bullets, fast-burning powders such as Benchmark, H4895, and CFE223 were tested. For the heavier 100+ grain bullets, Sierra tested a selection of medium-burn-rate powders including H4350, Reloder 16, Reloder 17, Varget, and Superformance. Sierra did a very thorough job. We know this information will be welcomed by 6mm Creedmoor shooters.
Don’t know what powder to try first? For the 107-110 grain bullets, if you want best accuracy and low ES/SD, our Forum members recommend Alliant Reloder 16 and Hodgdon H4350. If you are seeking max velocity with the 110-grainer, look at Hodgdon Superformance and Reloder 19.
Here are Sierra’s 6mm Creedmoor Load Data Charts for the 107gr MK and 110gr MK. There are a half-dozen other tables for lighter-weight bullets.

No, that’s not two shots — it is FIVE shots, with basically four in one hole and a fifth very slightly over. If that’s not impressive enough, consider this stunning 0.110″ group was shot at TWO HUNDRED yards — the length of two football fields. This amazing group was shot by Jack Neary at the 2019 World Benchrest Championship (WBC) held in Calgary, Alberta earlier this month.
Neary’s 0.110″ 200-yard group establishes a new WBC world record in the Light Varmint (LV) rifle class (10.5-lb max rifle weight). Jack was competing with Team USA “C Squad”, which also captured the WBC 2-Gun Gold Medal in the 4-man Team Championship.
World Benchrest Championships
The World Benchrest Championships are held every two years and attract competitors from over 20 countries. Jack Neary’s .110″ group is now a confirmed WBC 200-yard World Record for smallest 5-shot group. Neary was shooting a 6mm PPC hand-loaded with Vihtavuori N133 powder.
NOTE: This is a record for WBC competition. However, it is slightly larger than current NBRSA and IBS 200-yard Light Varmint (LV) records. The NBRSA LV 200-yard record is 0.075″ set by Johnnie Stewart in 2009. The IBS LV 200-yard record is 0.091″ by David Farrar in 2006. Still, Neary’s 0.110″ 5-shot group is a great accomplishment, set at the highest level of competition, at a match which had very challenging conditions.
Jack stated, “Vihtavuori’s temperature stability and cleaning burning attributes have been instrumental for competitors to achieve world record accuracy in the furthest corners of the world.”
Vihtavuori powders (predominently N133) were used by nearly every competitor (over 90%) during the World Benchrest Championship. VV N133 continues to dominate the short-range benchrest game. Notably, Vihtavuori powders have also been successful in the Extreme Long Range game, with VV powders used by recent KO2M winners. The next World Benchrest Championship will be held in Fall of 2021 in South Africa.
Neary Helps Team USA Win Gold at World Championship
Team Lapua’s Jack Neary, along with his Team USA “C Squad” teammates Harley Baker, Gary Bristow, and Jeff Graves, won the 4-Man Team Gold Medal at the 2019 World Benchrest Championship held in Calgary, Alberta, Canada this past week. Neary’s squad had the best overall Grand Aggregate, 0.2598, for the WBC combined 2-Gun Championship. Team USA “A Squad” took second place with a 0.2646 2-Gun Aggregate. CLICK HERE for WBC Team Championship Results.
All Team USA Gold Medalists used Lapua cartridge cases exclusively at the WBC. Lapua cartridge cases are known for superb quality of construction, using only the finest raw materials and superior annealing processes. Each case is machined to exacting dimensions. Lapua brass is renown for its superior consistency and longevity. The best brass also lasts the longest.
Neary stated, “Lapua cases are the foundation [for] our competition hand-loads[.] When competing at the highest levels against the most talented shooters in the world, we need the absolute best components available. There’s no doubt Lapua helped secure the Gold for Team USA.”

The .375 EnABELR cartridge was developed to offer magazine feeding capabilities with the highest-BC solid bullets available. Applied Ballistics observes: “The best magazine is one that retains the cartridge shoulder and doesn’t allow the tip of the bullet to impact the front of the magazine during recoil.” Cadex Defense has designed magazines that fit Cadex’s bottom metal and chassis for the EnABELR line of cartridges which allows for maximum magazine fed performance. These mags are beautifully made, but they will be very EXPENSIVE. Expect to pay about $275 per magazine — what the Cadex 375/408 CheyTac magazine currently costs (Product Code: MAG4300, USD $273.95).
Q: Is this different than Cadex’s regular CheyTac magazine?
A: Mitchell Fitzpatrick of Applied Ballistics Weapons Division replied: “Yes, the ribs that retain the shoulder are moved back to hold the case back and prevent the bullet tip from hitting the front of the magazine. We had been playing with inserts welded into place, which worked great, but dedicated mags directly from Cadex was the ultimate goal.”
Here is Mitchell Fitzpatrick, shooting the .375 EnABELR in an ELR Competition.
“CADEX and Applied Ballistics. Two companies taking ELR seriously and trying to get that last 1-2% of performance out of the system. Keep up the good work!” — Mark N.
The .375 EnABELR Cartridge — Big and Fast
The .375 EnABELR cartridge is slightly shorter than a .375 CheyTac so it allows the round to mag-feed. Applied Ballistics is currently using brass made by Peterson. The .375 EnABELR has achieved impressive velocities — 2990 FPS — with prototype Berger 379-grain solid bullets fired from a 1:7″-twist 30″ barrel. Applied Ballistics may also test 1:8″-twist and 1:9″-twist barrels. READ Bullet Testing Report.
The .375 EnABELR cartridge was designed to offer .375 CheyTac performance in a slightly shorter package: “The problem with the .375 CheyTac is that, when loaded with the highest performance .375 caliber bullets (379-407 gr Berger Solids, and the 400-425 grain Cutting Edge Lazers) the round is not magazine feed-able in any action that’s sized for CheyTac cartridges.
“Knowing the .375 CheyTac produced substantial performance, and that it was just too long for magazine feeding, made it easy to converge on a design for the .375 EnABELR. We just had to make the case short enough to achieve magazine length with the desired bullets, while adding a little more diameter to keep the case capacity similar to the .375 CheyTac. The resulting basic shape is quite similar in proportions to the successful .338 Norma Magnum Cartridge which, interestingly, was selected as the cartridge for General Dynamics Lightweight Medium Machine Gun (LWMMG).”
Philip Hemphill Wins NRA .22 Caliber Pistol Championship
Team Lapua member, Philip Hemphill, scored a 888-49X to bring home the 2019 NRA .22 Caliber Pistol Championship. Hemphill uses Lapua Center-X .22 LR Rimfire ammunition in .22 caliber disciplines such as Smallbore, PRC Silhouette, new ELR and more.
The 2019 NRA National Pistol Championships took place July 7-12 at Camp Perry, Ohio. Since 1907, the nation’s finest marksmen and women come together annually at Camp Perry to shoot a variety of handgun formats and events, both rimfire (.22 LR) and centerfire. The annual Camp Perry Championships represent the most prestigious bullseye pistol competitions in North America.
“It’s an honor to be able to come out here and test my shooting skills in one of the longest-running pistol events in the nation. My whole team, Team Zero, shoots Lapua Center-X, because we know it will outperform all other .22 Caliber [rimfire] competition ammo,” said Hemphill.
Along with receiving the Walker Trophy Plaque for winning the Championship, Hemphill also won the NRA Precision Pistol Championship (Police Division), and came in third in the .22 Caliber Slow Fire Match with a score of 194-9X.

See Photos from 2019 NRA Pistol Championships
Shooting Sports USA recently released a nice slide-show featuring 40 images from the 2019 NRA Pistol Championships at Camp Perry. SSUSA Editor John Parker noted: “A big thank you to Mr. John Rickards for his hard work on the firing line to grab the majority of these great images from the 2019 NRA Pistol Nationals at Camp Perry.”
Earlier this week, the California Rifle & Pistol Association (CRPA), filed a motion requesting an injunction against enforcement of California’s recently implemented ammunition sale/purchase laws. The injunction motion is part of the Rhode v. Becerra case filed in April of 2018. That lawsuit challenges California’s new ammo sale regulations which went into effect July 1, 2019. Lead Plaintiff and Olympic Shooter Kim Rhode and other Plaintiffs have asked the court to block the new ammunition-purchase laws on Constitutional grounds, and because of myriad practical issues with the new ammo sale controls.
Basically this burdensome new law requires filling out multiple forms, paying fees, and securing Birth Certificates or other proof of citizenship (which, of course, is NOT required for voting in California).
The NRA-ILA states: “The entire system has been shown to be an [unconstitutional] excessive burden on law-abiding gun owners with little to no law enforcement value. California ammunition retailers were given little if any guidance from the state explaining the procedures for processing ammunition sales, amounting to mass confusion throughout the state.”
We talked to Californian (and lead Plaintiff) Kim Rhode at SHOT Show. The Olympic Gold Medalist explained to us that she can no longer mail-order the high-quality shot shells she uses in Olympic and World Cup competition, and she is not able to find that ammo in California retail stores. This limits her ability to practice in California.
If the court grants the Plaintiffs’ request for injunctive relief, it will prohibit California from enforcing its confusing and burdensome ammunition sales restrictions while the Rhode case is fully litigated. A hearing on the motion for injunction is scheduled for August 19th, 2019. A decision is expected sometime thereafter.
The CRPA would also like to thank the following California ammunition retailers who supported Monday’s filing by providing declarations regarding the effect California’s ammunition sales restrictions have had on their businesses:
Turner’s Outdoorsman (27 CA locations)
LAX Ammunition OC (Huntington Beach)
Norco Armory (Norco)
Foothill Ammo (Shingle Springs)
Guns, Fishing and Other Stuff (Vacaville)
Royal Loan (San Diego)
Mosquito Creek Outfitters (Placerville)
Discount Gun Mart (San Diego and Santee)
The lawsuit is also supported by out-of-state retailers who are banned from shipping ammunition directly to California citizens, based on the provisions of the new legislation. These include Able’s Ammo (Texas), and Ammunition Depot (Florida).

The 17 Mach 2 (aka “17 HM2″) is making a come-back. We’re glad. This high-velocity round fits actions and magazines designed for the .22 LR, so it’s an easy barrel-swap upgrade for most rimfire bolt-guns (semi-autos are more complicated). The 17 Mach 2 cartridge doesn’t deliver the velocity of the 17 HMR, but it is still way faster than a .22 LR. Expect 2000-2100 fps with 17 Mach 2 compared to 1250 fps for “High-Velocity” .22 LR ammo. And, importantly, 17 Mach 2 ammo is much less expensive than 17 HMR. If you shop around, you can get 50 rounds of 17 Mach 2 for about $6.50. That’s 35% cheaper than the average $10 price of 17 HMR — a significant savings!
17 Mach 2 Major Selling Points:
1. 60% more velocity than typical “High-Velocity” .22 LR ammo.
2. 35% less cost than average 17 HMR ammo.
3. 17 Mach 2 OAL is compatible with .22 LR receivers and magazines.
17 Mach 2 Rifle Reviews
Gun-makers have taken notice of the availability of 17 Mach 2 ammo, introducing new models chambered for this versatile little rimfire round. For a high-volume, small-species varminting, the 17 Mach 2 is much more effective than the .22 LR, and much less expensive than the larger 17 HMR.
New Savage A17 in 17 Mach 2
There are a number of reviews on new-generation 17 Mach 2 rifles. Recently Varminter.com reviewed the Savage A17 in 17 HM2. Editor Eric Mayer wrote: “This new addition to the A17 line comes at a time when the 17 Mach 2 round is experiencing a resurgence, with ammo now available from CCI and Hornady, including the lead-free NTX round from Hornady. This means … you don’t have to break the bank to buy a current, functioning, semi-auto 17 Mach 2 and you don’t have to … convert your 10/22.”
Eric shot four different types of 17 Mach 2 ammo, putting 1000+ rounds through the Savage. He was impressed: “I am very excited that Savage Arms has chambered their A17 rifle in the 17 Mach 2 / 17 HM2 round. After shooting the prototype, I can confidently say that this new A17 will become my go-to 17 Mach 2 rifle. This new rifle is a great option for varminters everywhere!”
Toggle Bolt Volquartsen Summit in 17 HM2
It’s rare for us to see a new rimfire that we’d really like to own, but the new Summit from Volquartsen fits the bill. This versatile rifle features a cool, straight-pull toggle bolt, similar to those on elite Biathalon rifles. You can see how this gun shoots in this informative 22 Plinkster video:
22 Plinkster Tests Volquartsen Summit Rifle in 17 Mach 2
The 17 Mach 2 (17 HM2) is making a comeback. Now leading manufacturers are offering this efficient little rimfire cartridge in some nice rifles. Both Anschutz and Volquartsen will offer new 17 Mach 2 rifles in 2019. The Volquartsen Summit features a lightweight, carbon fiber-wrapped barrel threaded 1/2-28 for brakes or suppressors. The Summit boasts a nice 1.75-lb trigger pull. The Summit’s CNC-machined receiver features a +20 MOA Rail. NOTE: The video shows a silhouette-style laminated wood stock. However, the Summit comes standard with a composite Magpul stock that actually works better for shooting from a bench.
17 Mach 2 — Best Rimfire Bang for the Buck?
If you are looking for a capable, squirrel-busting round or a fun plinking round, you should definitely consider the 17 Mach 2, especially since CCI has committed to production of the little cartridge. CCI recently rolled out its “Gen 2″ 17 Mach 2 VNT Ammo with polymer tip (see top of article).
Considering that 17 HMR ammo is now running $10 to $12 a box, the 17 Mach 2 is an excellent value by comparison. It is available from many vendors for under $6.50 per 50ct box. That’s just $0.13 per round. When you consider overall “bang for the buck”, for many shooters, it makes sense to use the 17 Mach 2 rather than a 17 HMR. You save money, barrel life is a little longer, and the 17 Mach 2 is still a much more potent cartridge than the .22 LR. Check out this comparison, and note how the 17 Mach 2 has a much flatter trajectory than the .22 LR. For varmint shooting, the 17 Mach 2 is clearly the better choice.
Hornady’s 17 Mach 2 has a 2100 FPS muzzle velocity vs. 1255 FPS for “High-Velocity” .22 LR.
This article, in longer form, appears on the USAMU Facebook page, as part of the “Handloading Hump Day Series”. This article explores three different “Philosophies” of precision reloading. Some handloaders seek to produce ammo that yields the very tightest groups (without factoring in the wind). Other shooters load their ammo to deliver the highest safe velocity. That’s because a projectile launched at higher velocity will drift less in the wind. The theory is that even if fast ammo doesn’t produce the tightest groups in zero wind conditions, it will yield higher scores in a the real world (where the wind blows). Lastly, some handloaders favor ammo that is ultra-consistent across a wide temperature range. This last philosophy dictates selection of a powder that is temp-insensitive, even if it may not produce the very best raw accuracy (or speed).
What’s Your Handloading Philosophy?
Objectives of Reloading — Accuracy, Velocity, Temp Stability What do you, the reader, primarily value in your handloads?
Viewpoint ONE: Accuracy Trumps Everything
Some shooters prize consistent, excellent medium/long range accuracy enough that they’re willing to give up some extra velocity (and reduced wind deflection) to obtain that. Their underlying philosophy could be stated: “Superior accuracy is present for every shot, but the wind isn’t”. One’s ability to hold well, aim well and read the wind are all factors in making this type decision. The photo below shows stellar raw accuracy. This is an 0.67″, 10-shot group at 300-yards fired from a text fixture. The group measures just 0.67″. (This shows the USAMU’s 600-yard load with 75gr bullets).
Viewpoint TWO: Load to Highest Safe Velocity for Less Wind Drift
Some shooters value obtaining the highest safe velocity, even if one’s pure, consistent mechanical accuracy at medium/long range isn’t quite as brilliant. The theory here seems to be that a really good hold extracts as much mechanical accuracy from the rifle/ammo as possible, and faster bullets equal occasional “bonus” points snatched from the jaws of wind.
[For example] one of the USAMU’s many Service Rifle National Champions revealed his philosophy. It can be stated thus: a super-accurate, but [relatively] “slow” load “required him to have a Ph.D. in wind reading for every shot, while a faster, but less accurate load netted him more points.”
Note — this was not mere speculation; his score book data backed up his claims, due to less wind effects. Remember, however, this fellow has a consistent, National Championship-level hold, and other Champions on the same team would have opted differently.
Viewpoint THREE: Temperature Stability Is Key
Still another approach is to place heavy emphasis on fine accuracy with absolute stability in changing temperatures. When this writer was actively earning his Distinguished Rifleman badge, that was his goal. The reason? Sighting shots are not allowed in EIC (“Leg”) matches. The first shot out of the barrel was for score. It had to be 100% consistent, with very reliable, predictable elevation and wind deflection regardless of the ambient temperature — even if it wasn’t the lowest wind deflection possible.
Naturally, selecting a powder that is insensitive to temperature changes is a key element here. Elevation zeros and wind effects HAD to be consistent every time. Hunters and military snipers might be among those who fall into this camp, as well as those in pursuit of their Distinguished Rifleman badges.
Contrast that with a traditional High Power shooter who gets two sighter shots before each event (offhand, sitting rapid, prone rapid, prone slow fire.) If there is a zero change on any given day, he/she can correct during sighters. This writer well remembers talking with another very high-level Service Rifle competitor who was happy to have high temperatures boost the velocities of his ammunition above their usual level… As far as this SR competitor was concerned, 60-80 fps more velocity -– even if only due to high ambient temperatures -– meant less wind deflection, and he was mighty happy to have it.
Particularly in the summer, with hot daily conditions, you need to be concerned about temperature stability. Loads worked up in winter may not work in the summer time.
This article has been confined to NRA High Power Rifle competition, which has relatively generous 10-ring dimensions in relation to the accuracy of well-built competition rifles. Hopefully, it will provide food for thought. For some, this might be an opportunity to ensure that one’s load development approach helps them attain their desired results.

Hodgdon Varget and H4350 remain two of the most popular powders for a wide variety of cartridges. The big 8-lb jugs of Varget and H4350 have been hard to find, but Powder Valley has both in stock, at $194.50 per jug for H4350 and $194.50 for Varget.
We like CCI Blazer Brass ammo and here’s a great deal from Brownells.com. Get 1000 rounds of CCI Blazer Brass 9mm pistol ammo for just $194.99. This brass is reloadable.
This MTM ammo crate has been very popular with our readers. It ships with four (4) rugged, lockable ammo boxes, all of which fit together in a convenient, stackable carry crate. This is on sale now at Amazon for $22.99.
Lyman’s Ideal compact press works great as a second, lighter-duty press. For loading at the range, it can easily be mounted to a bench. This cast-iron press is stronger than other small presses in its class. The Lyman Ideal C-Frame press costs just $79.99 at Midsouth. With good leverage in a compact size, this is a great press for the price.

Choose single or continuous measurement (up to 8 seconds). Rated to 1000 yards on reflective objects, the PROSTAFF 1000i is a good, affordable option for hunters.
The Lyman BoreCam is an electro-optical borescope with a digital display. Our Forum members really like the BoreCam (although some wish the digital view-screen was larger). Midsouth now has the Lyman BoreCam for $199.99.
Here’s a quality AR15 lower, with nice FDE-color Magpul stock, at a very attractive price — just $159.99 at Palmetto State Armory (PSA). The adjustable stock is nice and PSA is one of the leading “Black Rifle” operations in the country.

Varminters take note — here’s a great deal on a 500-round “brick” of Hornady-brand 17 HMR rimfire ammo. This reliable, accurate ammo is ultra-effective on small varmints out to 200 yards. Save now with this Midsouth special, 500 rounds for $89.99. That’s just $0.18/round.

This is a VERY good tool with precise, adjustable depth control. In his product review, Jim See said: “The Frankford Arsenal perfect Hand-Priming Tool is legit — built heavy and strong. The [primer] seating depth adjustment is simple and accurate. Easy to operate.”
If you need an inexpensive front rest for field shooting and varminting, or as a back-up rest when shooting with friends, it’s hard to beat these Caldwell for the price — just $99.99 at Amazon. For under $100 you get a stable, durable rest. For just $9.58 more add a set of rubber foot pads.
Here is an affordable 24000mAh portable charge that has a VERY important feature — an LED read-out that display charge status and flow in/out. Priced at $30.99 on Amazon, this a good choice to charge your mobile devices and LabRadar.
Palmetto State Armory is selling the sub-compact Taurus 9mm with black frame for just $199.99 with FREE Shipping. This little gun has a comfortable grip and solid owner reviews. Despite its small size, the G2c has a 12-round magazine. We like the fact it has a left-side manual safety (unlike the Glock).
Fool would-be thieves with this guitar case gun carrier. This will hold a long gun up to 45″ overall. A carbine will easily fit inside, and a larger rifle will fit with stock separated from barreled action. This discrete carry case has wheels for transport and twin locking points.
Here’s a great combo deal. Graf’s is offering the Frankford Arsenal Case Prep & Trim PLUS the EZ Tumbler for only $179.99. That’s an amazing deal considering you could pay $199.99 or more for the Prep & Trim unit by itself, and the EZ Tumbler is regularly $50 or more.
When you’re at the shooting range — don’t forget the kids! These Amazon Basics ear muffs are sized for young girls and boys, and provide 20 dB NRR. We do recommend doubling up with plugs under muffs but these are a nice option, and very affordable at just $9.99 on Amazon.
This 12″x12″ Splatterburst Target combines splatter shot marking with a grid background. The bright neon shot circles make it easy to see shots. And the handy grid lets you quickly estimate group size. Get a 10-pack for $9.99, or a 25-pack for $17.99. This target has earned 87% FIVE-Star ratings.
Walkie-Talkies are “must-have” items for long-range shooting. The 22-CH Motorola T100 Two-Way Radio is an Amazon Best Seller in Handheld Radios. Priced at just $29.00 with Free Shipping, this set is a bargain.
One of our readers asked “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, the bullet behaves as if it has a higher ballistic coefficient.

The CRPA would also like to thank the following California ammunition retailers who supported Monday’s filing by providing declarations regarding the effect California’s ammunition sales restrictions have had on their businesses:
