Add another major National Rifle Championship to the list of shooting events cancelled in 2020. We’ve lost the CMP matches at Camp Perry, and the NRA High Power and Smallbore Championships at Camp Attebury in Indiana. Now the 2020 NRA National Silhouette Championships in Pennsylvania have been cancelled due to Pandemic concerns. Here is the official statement from the NRA:
Due to the COVID-19 pandemic and the many ensuing federal and state safety regulations and mandates, the Ridgway Rifle Club has made the difficult decision to cancel the 2020 NRA National Silhouette Championships which was to be held July – August 2020 at the Ridgway Rifle Club in Ridgway, Pennsylvania.
The NRA and the Ridgway Rifle Club share your disappointment that these competitions had to be cancelled.
A decision regarding the 2021 NRA National Silhouette Championship dates and location(s) will be announced later this year. The NRA and the Ridgway Rifle Club wishes everyone good health and the best of luck. For more information please visit Competitions.nra.org.
There is a great multi-part episode of ShootingUSA on the Outdoor Channel this week. This week’s show covers the Bianchi Cup, AR rifles from Colt and S&W, the historic Model 1903 Springfield, Smith & Wesson 10mm Model 610 Revolvers. Plus there is a bonus Pro Tip segment on how to mount and align riflescopes. If you receive the Outdoor Channel, you can see this excellent hour-long show today (5/13/2020) at 9:00 pm Eastern/Pacific, or 8:00 pm Central.
If you miss the show, or don’t get Outdoor Channel on cable, all ShootingUSA episodes are available “on demand” through Vimeo.com. You can subscribe for $3.99/mo, or watch any specific episode for a modest $0.99 fee. Under a buck for an hour’s entertainment? That’s a lot cheaper than going to the cinema.
Lead Feature: Bianchi Cup
27 years ago Doug Koening, who has won the Bianchi Cup 18 times, set the standard with a 1920 score. Since then, every Open shooter knows that he or she must “clean” this match (i.e. score a “1920”) to have a chance to take the title of “Champion”. The X-Count is the tie-breaker.
Feature: M1903 Springfield Rifle
The M1903 Springfield served in both WWI and WWII. The accuracy and quality and service life have clearly made the ’03 Springfield one of History’s Guns.
Feature: Smith & Wesson Model 610
The Smith and Wesson Model 610s are back and now chambered in 10mm. The Model 610 is a N frame, all stainless-steel construction, in a choice of barrel length – four inch, or six-and-a-half-inch.
Pro Tip — Mounting a Scope
In this episode, John Paul from JP Enterprises shows his method of Truing a Riflescope. He says: “If you’re going to be successful you need to lay down a solid foundation. One of those basic foundation blocks is making sure that your scope is true to the rifle.”
SUMMARY: This article reviews a device that “triggers” the LabRadar chronograph to register bullet speed. Rather than activate by sound or Doppler reading, this $35 JKL Inertial Trigger works from the rifle’s instantaneous recoil pulse when a shot is fired. After some frustration with his LabRadar when shooting at a range with reflective surfaces, our tester is now reporting that 100% of his actual shots are being captured correctly by his LabRadar chrono equipped with the JKL Inertial Trigger. He won’t use his LabRadar without it now. Other users have become instant fans of this inertial LabRadar trigger as well. It is very affordable and it works great. VIEW LARGE PHOTO.
JKL Inertial Trigger for LabRadar Chronograph
Product Review by F Class John
The LabRadar chronograph has been one of the most revolutionary tools in the shooting world because of how it collects velocity data, how it reports (and stores) that data, and, ultimately, the ease with which it can be positioned and operated. However, it’s not a perfect system. A majority of the complaints come from users whose LabRadar’s sometimes fail to record all the shots fired in a string. For the average plinker, this may not be an issue. But for serious shooters trying to do ladder tests or load development requiring all shots to be reported, it can be frustrating when a shot is missed.
Traditionally, LabRadar has recommended trying different settings that compensate for the gap between the unit and muzzle as well as well as having different options for how the unit recognizes a shot fired. While these options work to some degree, they aren’t a guaranteed fix especially when shooting at ranges with concrete baffles or with roofs, walls, and dividers that can alter sound waves. While nobody can precisely explain why shots are lost under certain circumstances, the fact remains it DOES happen. In addition, the default system can sometimes pick up stray shots from nearby rifles.
Not willing to give up on this sophisticated chronograph, many shooters have looked for a foolproof way to prevent such failures from happening. In fact, for this shooter, the frustration was so high that I actually sold my first LabRadar and went back to another chronograph before ultimately buying another LabRadar almost a year later. But I made that repeat purchase only after vowing to finding a way to make the LabRadar work — EVERY time, for EVERY shot.

JKL Inertial Trigger — Outstanding Product That Works Great
Enter the JKL Trigger for the LabRadar. This is an easy-to-use, inertial-driven trigger that activates simply from the recoil of your gun. The unit consists of a small rectangular pad attached to a long audio cable. All you do is plug in the audio cable, attach the pad to your gun with the provided hook and loop (Velcro) material. Then (important), you must change the LabRadar trigger settings from “Doppler” to “Trigger”. The unit works great and is easy to set up. In my experience, the unit will activate no matter where you place it on a stock. However the recoil of every gun is slightly different, so you will need to make sure you find a location that doesn’t interfere with your shooting setup.
An unexpected benefit of using the JKL trigger is that it gives you a larger area in which to place your Labradar unit, making it more convenient to setup on benches or range stations. I found this a welcome relief since the LabRadar originally seemed somewhat fussy about where I placed it. Now I can place the LabRadar in more convenient locations — as long as it’s still near my gun and pointed at the target correctly, I get consistent bullet speed data.
Are There Issues with “False Positives”?
If there is any downside to using the JKL Inertial Trigger, it’s that a very hard bump or aggressive working of the action can trigger a false reading. However these are easy to identify in your data, because the speed value is way lower than true fired shot values. Simply remove that low entry or otherwise ignore it in your calculations. To be fair, this “bump activation” really doesn’t happen very often once you get used to using the inertial trigger.
SUMMARY — Outstanding Accessory for LabRadar Users
Bottom line — if you own a LabRadar, then definitely get a JKL Inertial Trigger. Priced at just $35.00 this device is not expensive, yet it’s one of the most effective accessories you can buy for the LabRadar. I’ve recommended these inertial triggers to dozens of shooters. Every one of those guys who did buy a JKL trigger says they can’t imagine using a LabRadar without one. If you love what the LabRadar can do, but have been frustrated with shots not getting recorded 100% of the time, then definitely get yourself a JKL Inertial Trigger. It turns a good system into an amazing system. JKL Industries states that its inertial trigger “will work on anything from a .22 LR to a suppressed system or with standard rifle and brake.”
Ben Avery Re-Opens with Online Reservations
The Ben Avery Shooting Facility (BASF) in Arizona will soon be open for business again. However some key operational changes will affect customers. To ensure public health and safety, only online reservations will be accepted and shooters must observe social distancing rules and special range guidelines. BASF will at 7:00 am Wednesday, May 13, 2020. Reservations canbe made online now at Bookben.azgfd.com. Ammunition and safety gear can be reserved online, as well. NOTE: Reservations cannot be canceled or rescheduled.
At this time, the shooting facility is unable to accommodate walk-in customers on its rifle and pistol ranges, as well as the Clay Target Center (CTC). Any changes will be based on gradual reopening guidelines for businesses and customers, as outlined by the Governor’s Office.
“BASF’s implementation of a new online reservation system is two-fold: We want to maximize the shooting opportunities that this world-class facility has to offer, while maintaining common sense health practices,” said Mike Raum, shooting sports branch chief for the Arizona Game and Fish Department.
Located on 1,650 acres in north Phoenix, BASF is one of the nation’s largest publicly operated shooting facilities. A City of Phoenix “Point of Pride,” the facility has received a five-star rating from the National Association of Shooting Ranges.

If you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works. Your Editor uses it on his RCBS 2000 progressive press. I can affirm that a Lock-Out Die has “saved my bacon” a half-dozen times over the years when there was an over-charge (which could cause a Kaboom) or a low charge (which could cause a squib load).
The Lock-Out Die works by using a central die detection rod that sets its vertical position based on the height of the powder column in the case. Through an ingenious design, if the powder column height is too low or too high, the rod locks in place as you start to pull the press handle. This halts the press before the ram can lift and the cartridge plate can advance. Unlike a beeping alarm system (which can be ignored or defeated), the Lock-Out Die physically stops the movement of the press ram and prevents a bullet being seated in the “problem” case.
It takes a bit of tweaking to get the Lock-Out Die detection rod setting just right, but once it is correctly positioned, the Lock-Out Die works smoothly in the background. The Lock-Out Die won’t interfere with the loading process unless it detects a high or low charge — and then it positively stops the progressive loading cycle.
While crafted for use in RCBS progressive presses, the RCBS Lock-Out Die can also be used on a Dillon XL Progressive (see video below) or Hornady Lock-N-Load progressive — though it does take up one station which could otherwise be used for a final crimp die (after the seating die). The RCBS 2000 has one more station than a Dillon 550/650, so it’s an ideal platform for using the Lock-Out Die.

On the UltimateReloader.com website, run by our friend Gavin, you’ll find an excellent two-part series on the function and set-up of the RCBS Lock-Out Die. Part One explains how the Lock-Out Die functions, using cut-away illustrations. Part Two shows how to install and adjust the Lock-Out Die on various progressive presses. The video below shows setup of the RCBS Lock-Out Die on the Dillon XL-650 progressive press.

3. Bruno Shooters Supply — Huge Primer Sale
As primers have outstanding long-term shelf life, it makes sense to purchase primers in quantity when they are available at attractive prices. Right now Bruno Shooters Supply is running a huge PRIMER SALE featuring every brand and style in stock. Here’s a great opportunity to get a good supply of primers at attractive prices.
4. Camera Land — Konus 20-60x100mm Spotting Scope, $179.99
Spotting scopes are vital tools for shooters. But they can be pricey, especially those with large front objective lenses. Enter the Konus KonuSpot-100 20-60x100mm. The big 100mm objective gathers more light — good for low-light shooting and observing. For the money, this is a surprisingly good spotter (though don’t expect it to compare with a high-end Kowa, Swaro, or Zeiss). And if you order now you can get a camera adapter, carry case, lens cleaning cloth, and smartphone adapter at no extra charge.
With the stay-at-home orders, many shooters are using their new free time to get started in reloading. For novice reloaders, it makes sense to start with a kit that has most of the tools you need. The very affordable RCBS Partner Press Reloading Kit comes with Press, Powder Scale, Powder Funnel, Loading Block, Lube Tray, Neck Brushes, Dubur Tool, Load Manual and more. These Partner Presses work well for loading at the range, or use the compact Partner as a second press for depriming or bullet seating.

With the discounts and the free gear, we figure you can get over $600 in value.
9. Amazon — Real Avid Chamber Boss, $29.99
Cleaning AR-platform rifle chambers can be a pain, especially when it comes to removing the carbon. We found the Real Avid Chamber Boss is very effective on those dirty AR chambers and internals. The Chamber Boss includes a carbon scraper specifically designed for the AR chamber extension. This kit also include a chamber brush, and 5 special star-chamber cleaning pads. All these components fit right into the Chamber Boss’s handle, making transport simple and easy.
Here’s a great set of stick-on (adhesive) splatter targets. Shots appear as bright neon yellow halos — providing easy-to-see instant feedback. The $7.99 target packs include 10 sheets of black circles, 3″ in diameter, for shooting out to 300 yards and beyond. In addition, each sheet includes 8 smaller red center bulls plus 22 stick-on black dots. You can shoot the entire target sheet, or peel off one or more circles to stick on a target backer. These also work great indoors with pistols.
Recently we featured the Meprolight FT Bullseye Rear Sight. This innovative fiber-optic system provides a low-profile solution for carry pistols that eliminates the front blade sight. Now SIG Sauer (SIG) has incorporated this into an innovative new carry pistol, the SIG P365 SAS. This new pistol also features a ported barrel (for less muzzle flip), along with recessed controls. This makes the P365 SAS one of the smoothest, “snag-free” carry pistols ever made.
SIG states: “The P365 SAS was designed for the serious CCW user who truly understands the value of smoother draws, faster sight acquisition, and more effective engagements at realistic distances. This pistol does just that by taking the concept of the SIG Anti Snag (SAS) treatment to a whole new level. With the incorporation of the FT Bullseye sight embedded into the slide, the P365 SAS does away with the need of a primary snag hazard of all pistols — the front sight. With the assistance of fiber optics during the day and tritium in low light, the user can now obtain a crystal clear high-visibility bullseye sight picture at real-world engagement distances faster than ever before. The ported barrel and slide results in up to 30% less muzzle flip and zero front sight fouling, since there isn’t one. The flush slide catch and takedown levers ensure absolute smoothness and zero snag risk.”
There has been some controversy over the sighting system in low light but actual purchasers have said the sights work fine. There has been universal praise for the snag-free qualities of the gun. Here are posts from actual SIG P365 SAS owners:
“I’m convinced it is the best concealed carry on the market. The anti-snag is amazing. I can carry in my pockets on both jacket and jeans. Breakdown is easy and cleaning was simple. I like this gun so much I’m going back to buy one for my wife.” — Adguy304, WV
“After shooting well at the range, I went home and ran in the closet to test out the Tritium sights. I had a similar experience as others … the only thing I CAN see is my sight. It works well. It’s not as bright as when in a lit room, but it is visible. This pistol is challenging the norm on multiple fronts, and I’m very happy with the purchase.” — SASOwner
“To all those that truly carry this as a pocket gun you cannot find a better firearm. I purchased this about a month ago, got rid of four other handguns and this is the only one that I’ll need for this purpose. The Lima 365 is the ultimate point and shoot companion as it’s activated by the button on the grip and truly integrates with the 365 SAS.” — JSW, Miami
Do you find that the crosshairs in your scope get blurry after a while, or that you experience eye strain during a match? This is normal, particularly as you get older. Focusing intensely on your target (through the scope or over iron sights) for an extended period of time can cause eye strain. Thankfully, there are things you can do to reduce eye fatigue. For one — breathe deeper to take in more oxygen. Secondly, give your eyes a break between shots, looking away from the scope or sights.
In our Forum there is an interesting thread about vision and eye fatigue. One Forum member observed: “I have noticed recently that if I linger on the target for too long the crosshairs begin to blur and the whole image gradually darkens as if a cloud passed over the sun. I do wear contacts and wonder if that’s the problem. Anyone else experienced this? — Tommy”
Forum members advised Tommy to relax and breath deep. Increase oxygen intake and also move the eyes off the target for a bit. Closing the eyes briefly between shots can also relieve eye strain. Tommy found this improved the situation.
Keith G. noted: “Make sure you are still breathing… [your condition] sounds similar to the symptoms of holding one’s breath.”
Phil H. explained: “Tom — Our eyes are tremendous oxygen hogs. What you are witnessing is caused by lack of oxygen. When this happens, get off the sights, stare at the grass (most people’s eyes find the color green relaxing), breath, then get back on the rifle. Working on your cardio can help immensely. Worked for me when I shot Palma. Those aperture sights were a bear! The better my cardio got the better and longer I could see. Same thing with scopes. Try it!”
Watercam concurred: “+1 on breathing. Take a long slow deep breath, exhale and break shot. Also make sure you take a moment to look at the horizon without looking through rifle or spotting scope once in a while to fight fatigue. Same thing happens when using iron sights.”
Arizona shooter Scott Harris offered this advice: “To some extent, [blurring vision] happens to anyone staring at something for a long time. I try to keep vision crisp by getting the shot off in a timely fashion or close the eyes briefly to refresh them. Also keep moisturized and protect against wind with wrap-around glasses”.
Breathing Better and Relaxing the Eyes Really Worked…
Tommy, the shooter with the eye problem, said his vision improved after he worked on his breathing and gave his eyes a rest between shots: “Thanks guys. These techniques shrunk my group just a bit and every little bit helps.”
Read more tips on reducing eye fatigue in our Forum Thread: That Vision Thing.
To avoid eye fatigue, take your eyes away from the scope between shots, and look at something nearby (or even close your eyes briefly). Also work on your breathing and don’t hold your breath too long — that robs your system of oxygen.
Emily was just 8 years old when this photo was taken back in 2017. She’s now 11 but still enjoying shooting. Emily has won many awards — including a screamer at 1000 yards — and her accomplishments have not gone unrecognized.
English Emily and Her Record-Breaking 6mmBR Stolle
Report by Vince Bottomley
Turning back the clock a decade or so to 2006 and Accurateshooter’s Gun of the Week #71 you will see my smiling face and my 7mm WSM BAT which had just set a new UK Light Gun record for 1000-yard benchrest with a 5-shot group measuring 2.67 inches. That record has now been broken — sadly not by me but by Emily’s Grandfather with a gun I built for this talented schoolgirl. Here’s the story of the precocious Emily and her record-setting rifle…
In 2006, when I set the record, young Emily Lenton wasn’t even born but, a couple years later she arrived – into the shooting-mad Lenton family. Both father Bruce Lenton and Granddad Tony have represented their Country at European and World Benchrest Championships and it was no surprise to see Emily, at just eight years old in 2017, shooting in her first 1000-yard benchrest competition.
Emily Shoots 6mmBR Heavy Gun at 1000 Yards.
Recoil is always going to be a problem for a very young shooter, so Emily’s first bench-gun was Granddad’s 1000-yard Heavy Gun chambered for the 6mmBR cartridge. It hardly moves when Emily pulls the trigger and she soon became a serious contender. [Emily was 8 when she started, and is now 11 years old.]
Under her father Bruce Lenton’s careful supervision, Emily loads all her own ammunition.
Of course, she wanted her own gun and who better to ask to build it than the current record holder — me of course! Emily chose a Stolle action RBLP as this was to be a 17-lb Light Gun, bedded into a UK-made Joe West laminate stock. The barrel was a heavy-profile 1:8″-twist Krieger chambered in 6mm BR Norma (6BR) with a ‘no-turn’ neck (reamer from Pacific Tool & Gauge) and fitted with a UK Tier One muzzle-brake.
Emily’s Light Gun begins to take shape…
It was down to Granddad to help Emily with load-development and of course, he could also shoot it in competition — after all Emily had just about shot-out Granddad’s Heavy Gun with a full season of rapid-fire 10-shot groups!
Granddad Tony gets ready to shoot Emily’s gun.
Then something happened – Granddad went and broke my ten-year old record with Emily’s gun! Well, I suppose there was some consolation — at least I’d built the record-breaking gun. The new UK Light Gun 1000-yard five-shot record now stands at 2.462 inches. For those who like load details, Emily uses Lapua brass, Vihtavuori N150 powder, CCI 450 primers, and Berger 105 grain VLD bullets loaded with Wilson hand dies.
Tony Lenton with Emily’s gun just after he broke my 1000-yard record. I’m doing my best to smile!
Emily in New Zealand at 2017 World Benchrest Championships Down Under
Emily traveled down under to New Zealand in 2017 with her family. She helped her father and Granddad who were part of the United Kingdom squad competing at the 2017 World Benchrest Shooting Championships in Nelson, NZ.
Vince Bottomley reports: “Emily was a huge hit over in NZ — she was given the honor of hoisting the New Zealand flag at the opening ceremony, she drove the target changer’s buggy, did some impressive shirt-swapping”. Here she is wearing a Team Canada Jersey — a bit big for pint-size Emily.
The folks at Sierra Bullets asked a few staff bulletsmiths a classic question about guns: “If you could own only one firearm which one would you choose?” There were many interesting answers including a “cheater” response — the drilling — which is really two guns in one. The most-often mentioned chambering was the venerable .30-06. Respondents cited its versatility, hunting prowess, and ready availability of ammo. The popular .308 Winchester, as expected, got mentions as did its cousins the .243 Win and 7mm-08. There were quite a few votes for classic lever guns, as well as 12-gauge shotguns. Two bulletsmiths cited the .22 LR, and we can certainly see the logic in that answer. The little rimfire cartridge is versatile, quiet, and inexpensive.
We ask our readers the same question — if you could only have one long gun, what type of firearm would it be? List the gun type and chambering in the comments section.
If You Could Have Just One Long-Gun — ANSWERS:
Media Relations Manager Carroll Pilant answered: “I would NEVER own only one gun. If I HAD to pick one, it would be a drilling in 12 gauge over .30-06.”
Ballistic Technician Rich Machholz answered: “The early tang safety Ruger M77s pretty much have all you could want in a bolt gun, but I do like the Winchester lever guns and the combination guns, particularly the drillings. Since I have the first two, I’m going for a Doug Turnbull 1886 or a side by side 20 gauge over .223 drilling.”
Ballistic Technician Philip Mahin answered: “More than likely it would have to be a bolt action .30-06. The reliability is legendary on a wide range of game animals and factory ammunition has still been available at my local stores even in these tough times.”
Ballistic Technician Duane Siercks answered: “If I had to boil it all down to one gun, it would probably be a .30-06. I have a Remington 700C (custom shop gun) that has worked very well for anything and everything I have ever wanted to do with it.”
Ballistic Technician Paul Box answered: “A .22 Rimfire.”
Chief Ballistician Tommy Todd answered: “Remington 700 in .308 Winchester.”
VP – Sales & Marketing Matt Reams answered: “A light weight Kimber in 25-06.”
Production Toolsetter Brad Vansell answered: “Savage weather warrior 7mm-08 is my rifle of choice.”
Production Toolsetter Dan Mahnken answered: “The .308 Winchester rifle — [based on the] wide range of bullets made and the wide range of things that one can hunt with it.”
Process Engineer David Palm answered: “Savage action 243 Winchester.”
Ballistic Technician Gary Prisendorf answered: “Probably a .22 LR. It may not be the best choice, but you could use it for about anything if you really had to.”
Production Manager Chris Hatfield answered: “Beretta A300 Outlander 12 gauge.”
