Ruger Introduces New Ruger American Pistol

Ruger American Pistol new 9mm .45 ACP Auto

Story based on report in the Midsouth Shot Report Blog, MSSBlog.com.
Ruger (aka Sturm, Ruger & Co.) has just announced the new, full-size Ruger American Pistol (RAP), available in 9mm Luger and .45 ACP. The new RAP handgun is an well-thought-out, ergonomic design with many advanced features. Yet this new handgun is very affordable — both 9mm and .45 ACP models list for $579.00 MSRP. (Guns should be available at retailers very soon, with “street price” around $530.)

Ruger American Pistol new 9mm .45 ACP Auto
The new Ruger American Pistol features a pre-tensioned striker system, which allows for a short takeup trigger with positive reset.

The Ruger American Pistol is built on a one-piece, stainless-steel chassis with integral frame rails. It features a stainless slide with black-nitrided finish, Novak LoMount Carry three-dot sights, and a one-piece, glass-filled nylon grip frame with interchangeable backstraps. Up front is a mil-standard 1913 rail. Controls are fully ambidextrous. Importantly, unlike the Glock, you can field strip the Ruger American Pistol without pulling the trigger.

“The Ruger American Pistol is the most advanced semi-auto pistol we have ever produced,” noted Ruger CEO Mike Fifer. See other comments from Ruger’s CEO in this NRA-produced Video:

Ruger CEO Demonstrates New Ruger American Pistol:

The 9mm weighs in at 30 ounces with a 4.2-inch barrel and the .45 weighs in at 31.5 ounces with a 4.50-inch barrel. Both ship in a hard case with replaceable grip modules and two, nickel-Teflon plated steel magazines. Capacities are 17+1 rounds for 9mm and 10+1 rounds for .45 Auto. (There is also a 10-round version of the 9mm for states which restrict magazine capacity).

While developing RAP prototypes, Ruger polled law enforcement and military trainers throughout the country. Based on feedback from these LEO/military trainers, Ruger’s engineers worked to tame perceived recoil and reduce muzzle flip. The new pistol employs a barrel cam to spread recoil over time, a low-mass slide, and a low bore axis. All these elements work together to control muzzle rise and lessen felt recoil. The trigger is pretty smooth reports one early tester, who measured pull weight at just under six (6) pounds.

Ruger American Pistol Quick Review

One of the nice features of the Ruger American Pistol is the modular grip system. Three interchangeable wrap-around backstraps allow the RAP to fit a wide range of hand sizes.

SFC McPhail Aims for Olympic Gold in 50m Prone Rifle

Shooting Olympics prone smallbore 50 meter 50m ISSF World Cup Team USA
SFC Michael McPhail, shown above, is currently ranked #1 in the world in the smallbore 50m prone rifle discipline. He’s one of the favorites to win Gold in 2016.

Shooting Olympics prone smallbore 50 meter 50m ISSF World Cup Team USAAs the 2015 international shooting season comes to a close, the USAMU shooting teams are preparing for the 2016 Olympic trials and a chance to compete in the Olympic Games in Rio de Janeiro next summer. One USAMU marksman who has already secured a berth for the 2016 Olympics is SFC Michael McPhail of Darlington, Wisconsin.

SFC Michael McPhail, ranked number one in the world in men’s 50-meter rifle prone, already won his spot on the U.S. Olympic team by virtue of his performances in 2015 ISSF World Cup events. McPhail, of Darlington, Wisconsin, won the ISSF World Cup Finals in Munich this September. McPhail also won back-to-back gold medals at the ISSF World Cup events at Fort Benning, GA and Munich, Germany, held in May and early June of 2015.

McPhail said for anyone who wants to participate in the Olympics, the Army provides superior coaching, training, equipment and ammunition. “For a kid who shoots and their goal is to make the Olympics, the Army Marksmanship Unit is the place to go,” McPhail said.

SFC Jason Parker, International Rifle and Pistol Teams coach noted that: “Sergeant First Class McPhail has had a fantastic year. He has a great potential for medaling in the Olympic Games.”

With one seat already taken by McPhail for men’s 50-meter rifle prone, two other USAMU Soldiers are Parker’s top picks for the second and final seat. They are SFC Eric Uptagrafft and SSG George Norton. “Sergeant First Class Uptagrafft is another top contender for making the United States Olympic Team,” Parker said. “In the past, he has won multiple world class medals, he has been to two Olympics already, and he is one of our top shooters. He will be trying to get that last spot in the prone, and I wouldn’t count him out of anything.”

Ultimate Precision: Mac McMillan’s Historic .009″ Group

Mac McMillan .009 benchrest record group nbrsa.009″ — The Record That Stood for 40 Years.
In 1973 Mac McMillan shot an amazing 100-yard, .009″ five-shot group in a benchrest match. The .009″ group was measured with a 60x microscope for verification. Mac McMillan shot the group using a handbuilt prototype McMillan rifle with an early McMillan stock.

Mac’s .009″ group was the “Holy Grail” of rifle accuracy. This .009″ record was considered by many to be unbreakable, a record that would “stand for all time”. Well, it took 40 years, but someone finally broke Mac’s record with an even smaller group. In 2013, Mike Stinnett shot a .0077″ five-shot group using a 30 Stewart, a .30 caliber wildcat based on the 6.5 Grendel. Stinnett’s .0077″ group now stands as the smallest 100-yard group ever shot in registered benchrest competition.*
Read About .0077″ group HERE.

Stinnett’s success doesn’t diminish the significance of Mac McMillan’s .009″ group in the history of benchrest competition. For four decades Mac’s group stood as the ultimate standard of rifle accuracy*. For those of you who have never seen Mac McMillan’s .009″ group, here it is, along with the NBRSA World Record certificate. The target now hangs in the McMillan Family Museum.

*Somebody else might claim a smaller group, but unless moving backers or electronic targets were used, it cannot be verified. Moving target backers are used at registered benchrest matches to ensure that five (5) shots are actually fired in each group. That eliminates any doubt.

Hybrid Science: How to Load Hybrid Bullets for Best Accuracy

Berger Hybrid Bullet

SHOT Show 2016 kicks off in two weeks in Las Vegas. While at SHOT Show next month, we plan to get the “inside scoop” on new bullet designs from Berger, Hornady, Lapua, Nosler and Sierra.

A while back, at SHOT Show 2012 we chatted with Berger Ballistician Bryan Litz about Berger’s popular line of Hybrid bullets. Berger now offers a wide range of Hybrids in multiple calibers and weights. In fact, for .30-Caliber shooters, Berger now offers seven different Hybrid match bullets, with weights from 155 grains up to 230 grains. Two .338-caliber OTM Tactical Hybrids were introduced in 2012 (a 250-grainer and a 300-grainer).

Bryan tells us: “The hybrid design is Berger’s solution to the age old problem of precision vs. ease of use. This design is making life easier for handloaders as well as providing opportunities for commercial ammo loaders who need to offer a high performance round that also shoots precisely in many rifles with various chamber/throat configurations.”

For those not familiar with Hybrid bullets, the Hybrid design blends two common bullet nose shapes on the front section of the bullet (from the tip to the start of the bearing surface). Most of the curved section of the bullet has a Secant (VLD-style) ogive for low drag. This then blends in a Tangent-style ogive curve further back, where the bullet first contacts the rifling. The Tangent section makes seating depth less critical to accuracy, so the Hybrid bullet can shoot well through a range of seating depths, even though it has a very high Ballistic Coefficient (BC).

In the video we asked Bryan for recommended seating depths for 7mm and .30-Caliber Hybrid bullets. Bryan advises that, as a starting point, Hybrid bullets be seated .015″ (fifteen thousandths) off the lands in most barrels. Watch the video for more tips how to optimize your loads with Hybrid bullets.

Shooters’ Forum Upgrade Scheduled for Tonight

AccurateShooter Shooters Forum Software Upgrade

Here’s a “heads up” for our Forum members and site visitors. This evening, we plan to install new software for our SHOOTERS’ FORUM. As a result, the Forum will be offline for approximately 16 hours, starting at about 9:00 pm Central Time on December 27th. The Forum will remain off-line as we transfer all the data (600,000+ messages) to the server running the new Forum software. We anticipate this process will be conclude in the early morning hours of December 28th. If all goes well, we hope to have the Forum re-activated by noon on Monday, December 28th.

The new software gives us improved security and stability, and it should allow the Forum to run faster. In addition, the upgraded software is mobile-friendly so it will automatically adjust to the platform you are using — whether desktop, laptop, tablet, and even smartphone.

Current Forum categories and threads will be preserved, and we will maintain the general layout. But you will see some differences in link/button locations and in user profile screens.

Log-In Procedure (Read Carefully)
You will still be able to use your current Forum name and password. However, some users who changed their display name(s) will have to use their original name or original email address to log-in.

So guys… don’t freak out if you cannot access the SHOOTERS’ FORUM tonight. God willing, everything will be in place within a day. We’ve done a successful test, but there could still be some unanticipated hiccups. This is a MAJOR upgrade. If all goes according to plan, there will simply be a “time out” until mid-day on Monday.

The Dunbars — Father and Son F-Class State Champions

Winnequah Gun Club in Lodi, Wisconsin

Like father, like sons. Here’s a “feel-good” story about a father and two young sons. John Dunbar and his sons Brad and Zach attend F-Class matches together. John and Zach shoot, while young Brad helps in the pits and hauls gear for his brother and father. Working together, the Dunbar family has been quite successful in the F-Class game. Father John recently won the Wisconsin State F-Class Championship, while John’s oldest son Zach won the State F-Class Junior Championship that very same weekend.

The double Dunbar victories took place during the 2014 Gillespie Memorial Long Range Individual State Championship held last month at the Winnequah Gun Club in Lodi, Wisconsin. The battle for the F-Class (Open Division) Championship was largely a race between two Wisconsin shooters, Bob Sebold and John Dunbar. By the close of the Saturday matches, 2013 defending champion Sebold maintained a five X lead over his rival Dunbar. Both shooters had dropped a mere three points throughout the three match stages at 800, 900, and 1,000 yards.

The first Sunday match narrowed the gap between Sebold and Dunbar, with both shooters dropping two points apiece. Dunbar scored four additional Xs, allowing Sebold to retain the lead by a single X. The final 20-shot, 1,000-yard string determined the weekend’s Grand Aggregate champion. Dunbar scored an incredible 198-14X that clinched the title of Wisconsin State Long Range F-Class Champion.

Zach Dunbar Wins F-Class Junior State Championship
While John Dunbar secured one F-Class title, another, much younger Dunbar also made it to the winner’s circle. John’s oldest son Zach won the State F-Open Junior Championship that very same weekend. Zach had a comeback victory, overcoming a three-point deficit after the first day of shooting.

Youngest son Brad also helped secure the Dunbar family’s twin wins, cheering on family members while ensuring Team Dunbar remained hydrated on the firing line. From pulling targets in the pits to hauling gear across the range, young Brad’s efforts helped Team Dunbar finish first.

The range at Lodi is well-known for challenging wind conditions that are difficult to read. The 2014 Gillespie Memorial match proved to be no exception. Pick-ups and switches occurred with regularity, while mirage occasionally ran opposite to the wind flags lining the range.

Spots Still Available for Texas Youth Marksmanship Camps

Dustin Ellerman Marksmanship Camp Shooting Zavalla Texas Christian

You may not know it, but Top Shot Champion Dustin Ellerman is not just a great shooter. He’s also a youth camp director. Dustin runs a Christian-oriented camp in Texas. This spring, the camp will be offering weekend marksmanship camps for youngsters and teens. Dustin tells us that there are still a few spots available for the popular Kids’ Camp which offers a “Top Shot” type experience: “We have openings for the Kids’ Camps on February 20-21 and February 27-28. These are for kids ages 9-13. Sorry but the March 5-6 Teen/Parent Camp is full.” For more information, visit Marksmancamp.com.

Dustin Ellerman Marksmanship Camp Shooting Zavalla Texas Christian

At Camp His Way in Zavalla, Texas, Ellermann hosts weekend Marksmanship Camps for kids aged 9-13 and teens 14-18. The Christian-oriented camps focus on safety, marksmanship skills, and team building. Campers enjoy a host of fun skill-oriented activities: Airgun Shooting, Archery, Blowguns, Knife Throwing, Paintball Games, Slingshots, Tomahawk Throwing, and of course Rimfire Rifle Marksmanship with a variety of rifles.

Dustin Ellerman Marksmanship Camp Shooting Zavalla Texas Christian

The Kids’ (ages 9-13) Marksmanship Weekends cost $270. That fee includes all ammo, equipment, meals, lodging, team t-shirt, and one adult guest spectator. Parents are welcome to attend and spectate, but participation in marksmanship activities is limited to the kids at this time. CLICK HERE to reserve a spot — a few openings are still available.

Dustin Ellerman Camp His Way

Notice the young campers always wear ear and eye protection when shooting firearms. That’s as it should be. We wish adult shooters, including benchrest, smallbore, High Power, and F-Class competitors, followed this important safety practice.

Shooting Science: The Coriolis Effect Explained

Whittington Coriolis Effect
The Coriolis Effect comes into play with extreme long-range shots like this. The rotation of the earth actually moves the target a small distance (in space) during the course of the bullet’s flight. Photo by Dustin Ellermann at Whittington Center Range.

Coriolis Effect Bryan Litz Applied BallisticsWhen you’re out at the range, the Earth seems very stable. But it is actually a big sphere zooming through space while spinning around its axis, one complete turn every 24 hours. The rotation of the earth can create problems for extreme long-range shooters. During extended bullet flight times, the rotation of the planet causes an apparent deflection of the bullet path over very long distances. This is the ballistics manifestation of the Coriolis Effect.

Bryan Litz of Applied Ballistics has produced a short video that explains the Coriolis Effect. Bryan notes that Coriolis is “a very subtle effect. People like to make more of it than it is because it seems mysterious.” In most common shooting situations inside 1K, Coriolis is not important. At 1000 yards, the Effect represents less than one click (for most cartridge types). Even well past 1000 yards, in windy conditions, the Coriolis Effect may well be “lost in the noise”. But in very calm conditions, when shooting at extreme ranges, Bryan says you can benefit from adjusting your ballistics solution for Coriolis.

Bryan explains: “The Coriolis Effect… has to do with the spin of the earth. You are basically shooting from one point to another on a rotating sphere, in an inertial reference frame. The consequence of that is that, if the flight time of the bullet gets significantly long, the bullet can have an apparent drift from its intended target. The amount [of apparent drift] is very small — it depends on your latitude and azimuth of fire on the planet.”

Coriolis Effect Bryan Litz Applied Ballistics

Coriolis is a very subtle effect. With typical bullet BCs and velocities, you must get to at least 1000 yards before Coriolis amounts to even one click. Accordingly, Bryan advises: “Coriolis Effect is NOT something to think about on moving targets, it is NOT something to think about in high, uncertain wind environments because there are variables that are dominating your uncertainty picture, and the Coriolis will distract you more than the correction is worth.”

“Where you could think about Coriolis, and have it be a major impact on your hit percentage, is if you are shooting at extended range, at relatively small targets, in low-wind conditions. Where you know your muzzle velocity and BC very well, [and there are] pristine conditions, that’s where you’re going to see Coriolis creep in. You’ll receive more refinement and accuracy in your ballistics solutions if you account for Coriolis on those types of shots. But in most practical long-range shooting situations, Coriolis is NOT important. What IS important is to understand is when you should think about it and when you shouldn’t, i.e. when applying it will matter and when it won’t.”

The Coriolis Effect — General Physics
The Coriolis Effect is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object’s speed in the rotating frame.

A commonly encountered rotating reference frame is the Earth. The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time. This force causes moving objects on the surface of the Earth to be deflected to the right (with respect to the direction of travel) in the Northern Hemisphere and to the left in the Southern Hemisphere. The horizontal deflection effect is greater near the poles and smallest at the equator, since the rate of change in the diameter of the circles of latitude when travelling north or south, increases the closer the object is to the poles.

John Adams and Jerry Tierney Have Left the Range…
I also want to say a word in remembrance of two good men (and talented shooters) who really helped the site. John Adams, one of the site’s first Forum members, and a great supporter of our efforts, passed away just over a year ago. And we lost Jerry Tierney, a champion shooter in many disciplines, just this month. These men both served as mentors to me, and their knowledge (and good fellowship) will be missed. John and Jerry — rest in peace, my friends.

Crazy Days of Christmas — Having Fun with a .50 BMG

50 Caliber Barrett slow motion Christmas
50 Caliber Barrett slow motion Christmas

What could be more fun than decorating a Christmas tree? Well how about busting Xmas ornaments with a .50 BMG. Boys will be boys, right? This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame.

The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.

Top 10 Reloading Fails — Do You Agree?

Shooting Times Reloading Failures Mistakes Top Ten 10

Shooting Times has released an article entitled “Ten Most Common Reloading Mistakes”. Listed below are the Top Ten mistakes hand-loaders can make, at least according to Shooting Times. What do you think of this list — does it overlook some important items?

Top Ten Reloading Mistakes According to Shooting Times:

1. Cracked Cases — Reloaders need to inspect brass and cull cases with cracks.

2. Dented Cases — Dents or divets can be caused by excess case lube.

3. Excessive Powder Charge — Overcharges (even with the correct powder) can be very dangerous.

4. Primers Not Seated Deep Enough — “High” primers can cause functioning issues.

5. Crushed Primers — Some priming devices can deform primers when seating.

6. Excess Brass Length — Over time, cases stretch. Cases need to be trimmed and sized.

7. Bullets Seated Too Far Out — If the bullet is seated too long you may not even be able to chamber the round. Also, with hunting rounds, bullets should not engage the rifling.

8. Burrs on Case Mouths — Ragged edges on case mouths can actually shave bullet jackets.

9. Excess Crimp — This is a common problem with pistol rounds loaded on progressives. If case lengths are not uniform some cases will get too much crimp, others too little.

10. Inadequate Crimp — This can be an issue with magnum pistol cartridges in revolvers.

Do you agree with this list? We think some important things are missing, such as not adjusting full-length sizing dies properly. This can cause the shoulder to be pushed back too far (or not far enough). Another common mistake is using brass that is worn out, i.e. stretched in the case-head area from multiple cycles of hot loads. We also think the #1 error a reloader can make is using the wrong powder altogether. That can be a fatal mistake. See what happens when you load pistol powder in a rifle.

Shooters’ Stocking Stuffers — Eight Budget Gifts

Christmas is almost here, so today we’re featuring a hand-picked collection of “stocking stuffers” for precision shooters. So as not to bust your holiday budget, all of our selections are priced under $10.00. These items are handy tools that you’ll use over and over again at the range and/or at your loading bench (so you’re allowed to buy them for yourself, even after Christmas). Our AccurateShooter staffers use most of these items, including the Loading Blocks, Ballistol, Mirage Shades, Crocogators, and Barrel Bags.

Gifts $1 to $5 


Surveyors Tape
$1.99
Shooting Glasses S&W Safety
Safety Eyewear
$1.99
Hood quick estimator group size gauge
Hood Kwik Estimator
$2.50
Sinclair Barrel Mirage Shade
Barrel Mirage Shade
$4.95

Surveyors’ Tape. Always watch the wind when you shoot. Inexpensive, Day-Glo Surveyors’ Tape (aka “Flagging Tape”), attached to a stake or target frame, makes a good wind indicator. It will flutter even in mild breezes, alerting you to both angle and velocity shifts. This should be part of every range kit. Don’t leave home without it.

Safety Eyewear ANSI Z87.1. Yes you can get ANSI-approved Safety Eyewear for under two bucks. At that price you should pick up a half-dozen sets, just so you have extras. We recommend that shooters wear eye protection at all times when handling firearms. This eyewear special is offered by CDNN Sports. Call 800-588-9500 to order.

Hood Kwik Estimator. Here’s a very handy tool to measure your 6mm groups. Bracket the group within the diverging lines of the Kwik Estimator and you’ll instantly get a good approximation of the actual group size. No more trips to the tool box for calipers. The inexpensive Kwik Estimator fits in a shirt pocket. (Thanks to Boyd Allen for this suggestion.)

Sinclair Barrel Mirage Shade. For high-volume varminters, and competitors who shoot fast in warm weather, a mirage shield is absolutely essential. This prevents hot air rising off the barrel from distorting the image in your scope. The aluminum Sinclair shield can be trimmed to fit, and comes with stick-on Velcro attachments. Two lengths are available: 18″ for short BR barrels, and 24″ for longer barrels.

Gifts $6 to $10 


Dewey Crocogator
$6.50
Ballistol multi-purpose gun lube
Ballistol Aerosol Lube
$8.99
Sinclair Barrel Storage Bag
Sinclair Barrel Bag
$9.95

Sinclair Load Block
$9.99

Dewey Crocogator. The Crocogator tool, with knurled “teeth” at both ends, is simple, inexpensive, and compact. Yet nothing zips though primer-pocket gunk faster or better. Unlike some cutter-tipped primer pocket tools, the Crocogator removes the carbon quick and easy without shaving brass. One end is sized for large primer pockets, the other for small.

Ballistol Aerosol Lube. Ballistol is a versatile, non-toxic product with many uses in the reloading room. We have found it is ideal for lubricating cases for normal full-length sizing. It is clear, not gooey or chalky like other lubes. It is very, very slippery, yet is easy to apply and just as easy to wipe off. As you lube your cases, the Ballistol will also clean powder fouling off the case necks. For heavy-duty case forming and neck expansion, we’ll still use Imperial die wax, but for every-day case sizing, Ballistol is our first choice. It also helps prevent your dies from rusting and it even conditions leather. Ballistol is a favored bore cleaner for Black Powder shooters because it neutralizes acidic powder residues.

Santa Christmas Stocking giftsSinclair Barrel Bag. If you run a switch-barrel rig, or take spare barrels to a big match, this simple but effective barrel bag will protect your valuable steel. The bag is moisture-resistant vinyl on the outside with a soft, quilted interior to protect the barrel’s finish and delicate crown. There are two sizes: one for barrels up to 26 inches, the other for barrels up to 31 inches. Both sizes are priced at $9.95 per bag. That’s cheap insurance for those priceless barrels.

Sinclair ‘Poly’ Loading Block. We’ve tried wood and injection-molded loading trays, and we prefer Sinclair’s white polyethylene loading blocks. They featured chamfered holes properly sized for the particular case you reload. The blocks are heavy enough to be stable on the bench, and the “dishwasher-friendly” material is easy to clean. The standard Poly Loading Block holds 50 cases, while the Competition Loading Block holds 25 cases with a tray for empties. For a bit more money, there’s also a Heavy-Duty 50-case model with an extra-thick 1″ base.

PMA Tool Offers Adjustable Stock Weight System

PMA Toll weight system

PMA Tool now offers a unique “adjustable” Stock Weight System with variable weighting from 2 to 8 ounces (including internal sleeve). This $65.95 system allows the shooter to add or remove weight (in the buttstock) to balance the gun, or adjust the weight to meet class weight limits. Say, for example you were running at max weight but then changed your scope for a new optic that weighed 4 ounces less. With this system, you can easily get back up to the “legal limit”. You can also use the weight to adjust balance when running barrels of different lengths or contours.

The PMA Stock Weight system is made up of a sleeve, a nut and three interchangeable weights. The sleeve and nut weigh 2 ounces (combined) and weight inserts of 2, 4 and 6 ounces are included in the system. The sleeve is machined from aluminum, while the nut and weights are machined from stainless steel. All weights are roll-stamped with their weights and “coin-slotted” so they can be easily installed using a screwdriver or coin. The nut utilizes a 1/4″ hex wrench for removal from the sleeve and installation of weights.

While installation of these Stock Weight Systems is fairly simple, PMA states that: “The sleeve should be installed into the buttstock by someone with some mechanical aptitude and an understanding of stock construction, preferably a trained gunsmith or stock-fitter.”

New Case Gage Depth Micrometer from L.E. Wilson

L.E. Wilson Depth Case Gage Gauge Bump Shoulder Headspace

Here is an interesting new measuring device from L.E. Wilson, makers of precision hand dies, case trimmers, and other precision tools. This new Case Gage Depth Micrometer measures shoulder “bump”, so you can determine your headspace both before and after Full-Length sizing. With this Depth Micrometer, you can ascertain exactly how much your FL-sizing die is pushing back the shoulder during the sizing process. While you can measure shoulder setback with comparators on calipers, this Wilson Depth Mic is much more handy. Just place your sized round in the base gage and then slip the micrometer over the top. Take a measurement before FL sizing and then, after sizing, click the micrometer top to verify the amount of shoulder set-back. The measurement is quick and repeatable — very slick.

This is one more nice product from the folks at L.E. Wilson. The $110.00 tool comes with a Gage Block and micrometer top with .001 gradations. The Depth Mic top is compatible with all other Wilson case L.E. Wilson Gages (one size works for all).
