Forum member Jacob spotted this simple, but effective set of scope ring inserts on the Brownells Website. With these inserts, you can use a scope with 1″-diameter main tube in 30mm rings. Non-marring, matte black Delrin sleeves surround the scope tube so it can fit larger-diameter rings. Each sleeve comes in two parts for easy installation around your scope tube. This way you can use the same 30mm rings for all your scopes.
Ring Reducers are sold as front/rear kits. Cost is $16.99 for the Delrin 30mm to 1″ converters, item 084-000-091WB. There are also sets that reduce 30mm rings to 26mm, and 1″ rings to 3/4″ or 7/8″.
Note: These Brownells units simply function as plastic bushings. Unlike Burris Signature Ring inserts, they do not allow you to “pre-load” windage or elevation. If your rings are misaligned, the Brownells Ring Reducers won’t correct that problem.
Sherri Jo Gallagher, the second woman in history to win the NRA High Power National Championship, sports Eye Protection at Camp Perry. The first lady High Power Champion was Sherri’s mother, Nancy Tompkins.
In response to a Bulletin article about Protective Eyewear, one of our Canadian readers posted a personal story. His account demonstrates the importance of wearing eye protection whenever you shoot — no matter what type of firearm you are using — even air rifles. We hope all our readers take this to heart. All too often at rifle matches we see shooters, even some top competitors, risking their vision by failing to wear eye protection.
Eye and Hearing Protection are now MANDATORY for Highpower Rifle competitors and Pistol shooters in all CMP-affiliated matches. The 2020 CMP Highpower Rifle, Pistol, and CMP Games Rulebooks all contain the following rule: “All competitors and competition officials are required to wear appropriate eye and hearing protection when on shooting range firing lines during highpower rifle or pistol firing. All competitors must comply with this requirement before they can participate in a CMP sponsored or sanctioned competition. Competitors are responsible for selecting their eyewear and hearing protection.”
Eye Protection — Lesson Learned by Nicholas from Canada
As a boy on a mixed farm on the plains the first shooting stick I owned was a Red Ryder BB gun. My Dad bought it for me as I showed a keen interest in the shooting and hunting sports. I was about 9 years old at the time.
We had literally thousands of sparrows in our large farm yard and they liked to roost on the steel railings in the barn loft. I took to slowly thinning out their ranks by flashlight at night as these little winged pests settled in the farm buildings.
One evening as I slayed sparrow after sparrow in the barn loft — with about a dozen farm cats following me to consume these easy meals, I fired at another bird centered in my flashlight beam.
However, my aim was a bit low — and the copper pellet hit the steel beam square on. Instantly I felt a sharp pain as the BB bounced back and hit me squarely between the eyes on the bridge of my nose – drawing blood from the partial penetration into the skin. A half inch either way and I’d have lost an eye!
Never, never, never shoot at any target with a steel background with any firearm, even a BB gun – is the hard lesson I learned, and wear the best shooting glasses that money can buy!
PLEASE REMEMBER THAT!!
Editor’s Comment: Among competitive pistol shooters, the use of safety eyewear is universal. You’ll never see Rob Leatham, Julie Golob, or Jerry Miculek competing without eye protection — for good reason. The handgun sports’ governing bodies effectively enforce mandatory eye protection policies. We wish the same could be said for competitive rifle shooting. We often see benchrest, High Power, and F-Class competitors shooting without eye protection. We’ve heard all the excuses, yet none of them trump the safety considerations involved.
We recommend that all shooters and hunters employ eye protection whenever they use firearms or are at a location where live fire is taking place. You only have two eyes. A tiny bullet fragment or ricochet is all it takes to cause permanent blindness in one or both eyes. As rifle shooters, we place our eyes a couple inches away from a combustion chamber operating at pressures up to 70,000 psi. I know quite a few guys who will religiously put on safety glasses when running a lathe or a drill press, yet the same guys won’t use eye protection when shooting their rifles — simply because it is “inconvenient”. That’s nuts. It doesn’t matter is you are a cub scout or a multi-time National Champion — you should wear eye protection.
I will give you a personal example. A year ago I was shooting a 9mm pistol. One of the cartridges had a primer burst outward blowing small particles, some brass, and a piece of the pistol’s extractor right back into my eyes. Thankfully I was wearing good wrap-around safety glasses. No injuries at all. But without those safety glasses, this could have been very serious. I always wear safety glasses with ALL firearms. Shown below is the same kind of primer blow-out I experienced, but with a .270 Win rifle cartridge.
Be wise — protect your eyes. To learn more about eyewear safety standards, and to learn about the latest options in ANSI Z87-certified protective eyewear, read our article on Eye Protection for Shooters.

NRA Media offers a series of 40 informative videos about the Science of Shooting, covering a wide range of topics, from eye dominance to long-range ballistics. These videos feature high production values, with super-slow motion segments, as well as helpful computer graphics to illustrate the principles covered.
The videos are narrated by Jessie Duff, a top action pistol shooter (and the first women ever to achieve USPSA Grand Master status). Jessie is assisted by talented shooters such as Top Shot Season 4 Champion Chris Cheng. There are forty videos in the Firearm Science Video Series. Here are five NRA videos, with links to others below. You’ll find all 40 NRA Firearm Science Videos HERE.
Eye Dominance — How to Determine Which Eye is Dominant
Host Jessie Duff and longtime shooter Krystie Messenger demonstrate how eye dominance affects aim and teach you how to determine your dominant eye in this edition of Firearm Science. There are very simple tests you can do to determine your eye dominance. This Editor is right-handed but left-eye dominant. All competitive shooters should check for eye dominance. If you are cross-dominant, you can alter your head position or put a paper patch on one frame of your shooting glasses.
Eye Protection — Effect of Different Color Lenses
No matter what you’re shooting, eye protection should always be worn. But with so many choices, what should you wear? In this edition of Firearm Science, two-time Olympic trap shooter Corey Cogdell explains lens color options for protective eyewear. Different colors may be selected according to the light conditions and the sport. For most rifle shooters using magnified scopes, clear lenses are probably the best choice, except on very bright summer days.
Iron Sights vs. Optics
Host Jessie Duff and shooter Krystie Messenger demonstrate the benefits and drawbacks of using iron sights and optics in this edition of Firearm Science. For AR-type rifles, choosing the right option depends on the intended use of the rifle and the rules of competition. For example, a “Standard military Rifle” for CMP competition must have iron sights. But current NRA service rifle competition (and CMP unlimited military rifle class) allows scopes. Olympic smallbore shooters and Palma shooters have shown that extreme accuracy IS possible with sophisticated target sights. Below is the iron-sights Palma rifle with which John Whidden (Whidden Gunworks) won NRA Long-Range National Championships.

With today’s Saturday video showcase we feature eight videos from the Popular Backfire YouTube Channel. The host of the BackFire channel, Jim Harmer, also has a good website, Backfire.tv with written reviews. If you’re shopping for a hunting rifle we recommend you read the recent (12/1/2025) Best Hunting Rifles article. Without further ado, here are eight noteworthy videos from the BackFire Channel.
Five Powder Dispenser Comparison Test (All Units Purchased)
If you are in the market for a sub-$500 electronic powder dispenser, definitely watch this review. This Backfire comparison test is notable because the tester spent his own money to purchase all five powder dispensers being reviewed. That means Backfire could tell the full truth, both good and bad, about the machines. In fact, Backfire bought TWO ChargeMaster Lites because one failed (See 14:12 time-mark). The reviewer liked the RCBS ChargeMaster Supreme, but his top choice overall was the Hornady Auto Charge Pro. He favored the overall design, and really liked the way the dispensing speeds could be easily set faster or slower. Here are highlights from the video review:
00:08 Speed Test
03:09 Accuracy Test
07:57 Frankford Arsenal Intellidropper
09:08 Lyman Gen 6
10:44 RCBS Chargemaster Supreme
12:03 Hornady Auto Charge Pro
14:12 RCBS Chargemaster Lite
14:41 Conclusions
Best Rifle Scope Under $500 (2.2 Million Views)
This is a very comprehensive test of ten scopes under $500 MSRP. Unlike many reviews, the tester actually purchased all the tested scopes with his own money to provide a fair, unbiased review. The ten scopes all have approximately 4-14X magnification, common for a hunting/general purpose field scope. The reviewer ranked the $349 Vortex Diamondback Tactical FFP as the Best Overall scope. The reviewer’s first choice for a Target/Competition scope was the $299 Arken 4-16×50 model. The $175 Burris Fullfield E1 Hunting model was named the best “Lightweight, Capped Scope”.
The Backfire team purchased eight rangefinders and tested them in the field. Most of the products are under $500. This is a good review if you are looking for a compact LRF at a moderate price. Looking at performance for the price, for the hunting market, the reviewers favored the Leupold RX-1600 and the waterproof Vortex Ranger 1800. COMMENTARY: If you can afford it, we recommend that serious hunters consider top-end laser rangefinder-equipped binoculars such as the ZEISS Victory RF and Leica Geovid.
Affordable Hunting Rifles under $750.00 (1.3 million views)
Here’s another good Backfire Channel video for hunters looking for a new rig. With hunting season starting soon, this video can save you time and help you get the most bang for your buck. The Backfire team review eight affordable under-$750 rifles: Bergara B-14, Howa 1500 Hogue, Kimber Hunter, Remington 700, Ruger American, Savage 110 Switchback, Tikka T3X Superlite, and Weatherby Vanguard. The Backfire reviewers tested all 8 rifles for function and accuracy (4-shot groups). These 8 rifles were chose for review based on input from Backfire channel viewers.
Accuracy Secrets of a Champion — Interview with Erik Cortina
Our friend Erik Cortina is one of America’s top F-Class marksmen, and he has also achieved notable results in some long-range tactical matches. In this video Erik explains some of the factors that help in load development, wind reading, and achieving long range accuracy. If you shoot F-Class or even just compete in local matches, this video is worth watching. Erik’s Cortina Precision company produces high-quality tuners, tuner brakes, dies and other high quality products.
How to Set Up a Rifle for 1000 Yards
Here’s good video for novice ELR and Long range shooters. The video covers initial zeroing and then working with ballistics at 600-1000 yards. The tester explains the importance of a very stable platform and optics with adequate vertical adjustment and proper parallax control. The featured rifle is a 6.5 Creedmoor Bergara Premier Competition in a dark, gray PMA chassis (this is not the tan rifle in cover shot). Note: Bergara also offers a barreled action that you can put into a different chassis of your choice. The scope is an Athlon Helos BTR Gen2 4-20x50mm. A Garmin Xero C1 radar chrono was used to confirm velocity.
Low-Cost vs. High-Cost Rifles — How They Compare (2 Videos)
Here are two interesting videos that compare the features and performance of rifles at various cost points. The first video compares two rifles with a 10X (1000%) price difference — $350 vs. $3500. Some quite inexpensive rifles can perform very well, if you get lucky with the factory barrel. At the high end of the spectrum you can (hopefully) expect a smoother action, better trigger, more sophisticated stock, and (hopefully) more shot-to-shot consistency. Still a big investment doesn’t always guarantee vastly improved performance. For a deer hunter, a $500 rifle with a modestly-priced scope can probably do the job. If you want to hit prairie dogs at 500 yards and beyond, you’ll need an accurate cartridge and a very good (preferably custom) barrel for consistent hits.

When shooting any match that requires moving back and forth between multiple target distances it is very handy to have your ballistics data, i.e. your “come-ups”, placed within easy view. That way you can instantly see your elevation for various target distances in seconds. This can really help a PRS/NRL competitor on timed stages. And having a convenient “Dope” display of elevation at various distances can also benefit varminters who are shooting critters. In our varmint hunters we targeted p-dogs from about 80 yards out to 500+.
PRC DOPE Roller QD Ballistic Data Turret
The PRC DOPE Roller QD Ballistic Data Turret provides a handy, low profile display of windage and elevation data. You can see your “dope” without breaking position from behind the rifle. Then simply rotate the knob to display data from various distances. The ballistic data is placed by wrapping a simple 1″ x 3″ adhesive address label around the outside surface of the DOPE Roller. This handy quick-detach roller retails for $64.95 from Precision Rifle Components.
MDT M-LOK Data Card Holder
The MDT M-LOK Data Card Holder has an adjustable neck allowing you to easily position your ballistics data for optimal viewing. Data entries are written on on a reusable card that attaches with Velcro. The Data Card Holder Kit comes with hardware to mount to any M-Lok rail. In addition the card holder fits directly to an MDT ACC chassis attachment point. This MDT kit includes: M-LOK Data Card Holder, Wet Erase Data Card, Wet Erase Marker, and installation hardware. NOTE: The Card Holder sticks out about 6.7″ when fully extended, but arm links can be removed to make the arm shorter. The unit folds flat for storage. This complete kit is $59.95 at Creedmoor Sports.
Warne Universal Data Card Holder
The Warne Universal Data Card Holder easily attaches to the scope tube, in left or right configurations, for a universal fit. Data is displayed in a convenient location to make quick and accurate target transitions, and the articulating arm allows for low profile storage while not in use. The Warne Universal Data Card Holder retails for $88.49 at Warnescopemounts.com. Three ring sizes are offered: 30mm, 34mm, 35mm. A 50-pack of Warne Data Card label refills is currently $16.99 from Warne.
Scope-Cover Mounted Ballistics Table
Another option is to place your ballistics card on the back of the front flip-up scope cover. This set-up is used by Forum member Greg C. (aka “Rem40X”).
With your ‘come-up’ table on the flip-up cover you can check your windage and elevation drops easily without having to move out of shooting position.
Greg tells us: “Placing my trajectory table on the front scope cover has worked well for me for a couple of years and thought I’d share. It’s in plain view and not under my armpit. And the table is far enough away that my aging eyes can read it easily. To apply, just use clear tape on the front objective cover.”
Cheap But Effective — Tape on the Stock with Ballistics Data
At the 2021 Nightforce ELR Steel Challenge, Applied Ballistics guru Bryan Litz wrote his come-ups on blue masking tape applied to his stock. He did this based on a tip from Chase Stroud. With the tape applied behind the action, the numbers are easily visible. This “cheap trick” does work apparently — Bryan won the match with a convincing victory over 220 other shooters. READ Match Report.
Cheap But NOT So Effective — Numbers on Hand
Many of us have scribbled some come-ups on the back of a hand or on our forearm using a marking pen. That can work if you only have a couple distances to deal with — say 100 and 300 yards. But if you want a more complete Come-up table, get one of the card-holders shown above. Writing numbers on the skin is generally not such a good idea….
Do you know which one of your eyes is dominant? It’s easy to determine eye dominance with a simple exercise. Pick an object about 6-10 feet away (a light switch or door knob works well). Make an “OK” sign with your right hand (see photo) and hold that about 18″ from your face. Now, with both eyes open, look through the circle formed by your thumb and index finger. Center the circle on the object, so you can see the object in the middle.
Now, here’s the important part — while still holding your hand up, centered on the object, first close your right eye. If you don’t see the object anymore, then your right eye is dominant. If you still see the object, then repeat the procedure with the left eye shut and right eye open. If you don’t see the object when your left eye (only) is closed, then you are left-eye dominant.
The digital archives of Shooting Sports USA contain many interesting articles. A while back, Shooting Sports USA featured a “must-read” expert Symposium on Eye Dominance, as it affects both rifle and pistol shooting. No matter whether you have normal dominance (i.e. your dominant eye is on the same side as your dominant hand), or if you have cross-dominance, you’ll benefit by reading this excellent article. The physiology and science of eye dominance is explained by Dr. Norman Wong, a noted optometrist. In addition, expert advice is provided by champion shooters such as David Tubb, Lones Wigger, Dennis DeMille, Julie Golob, Jessie Harrison, and Phil Hemphill. NOTE: If the story doesn’t open at the links, go to the ssusa.org home page first, indicate you are over 18, and then CLICK HERE.
Top Rifle Champions Talk About Eye Dominance:
David Tubb — 11-Time National High Power Champion
I keep both eyes open, always. Some use an opaque blinder in rifle or shotgun shooting. If you close your non-dominant eye, you will not get as good a sight picture. If your aiming eye is not your dominant eye, you have even more of a problem to overcome.
Lones Wigger — World, National and Olympic Champion Rifleman
Shooters should try to use the dominant eye unless the vision is impaired and the non-dominant eye has better vision. You should always shoot with both eyes open since this will allow the shooting eye to function properly.
Dennis DeMille — National Service Rifle Champion
I close my non-shooting eye initially. Once I pick up my sight picture, it’s not something I focus on. For those that use a patch, I recommend that they use something white to block their view, rather than cover the eye.
Bruce Piatt — 2025 World Action Pistol Team Championship — Member of Winning Team CMP-USA
Some shooters, especially those with nearly equal or cross-dominance, will naturally find themselves squinting one eye. When anyone does this, you are also closing your dominant eye to some extent and adding stress to your face.
