Neck Tension on Bullets — Neck Bushing Size is Only One Factor

case neck bushing reloading die tension bullet release

Many novice hand-loaders believe that neck bushing Inside Diameter (ID) size is the only important factor in neck tension. In fact, many different things will influence the grip on your bullet and its ability to release from the case neck. To learn more about neck tension and “case grip”, take the time to read this article carefully. We bet you’ll gain knowledge that will let you load more accurate ammo, with better ES/SD.

Editor: Guys, this is a VERY important article. You really should read it over carefully, twice. Variations in the force required to release a bullet can significantly affect accuracy and ES/SD. You really need to know how the grip on bullet can be altered by many different factors.

Neck Tension (i.e. Grip on Bullets) Is a Complex Phenomenon

While we certainly have considerable control over neck tension by using tighter or looser bushings (with smaller or bigger Inside Diameters), bushing size is only one factor at work. It’s important to understand the multiple factors that can increase or decrease the resistance to bullet release. Think in terms of overall brass-on-bullet “grip” instead of just bushing size (or the internal neck diameter in non-bushing full-length sizing dies).

Bullet grip is affected by many things, such as:

1. Neck-wall thickness.
2. Amount of bullet bearing surface (shank) in the neck.
3. Surface condition inside of neck (residual carbon can act as a lubricant; ultrasonic cleaning makes necks “grabby”).
4. Length of neck (e.g. 6mmBR neck vs. 6mm Dasher).
5. Whether or not the bullets have an anti-friction coating.
6. The springiness of the brass (which is related to degree of work-hardening; number of firings etc.)
7. The bullet jacket material.
8. The outside diameter of the bullet and whether it has a pressure ridge.
9. Time duration between bullet seating and firing (necks can stiffen with time).
10. How often the brass is annealed.
11. Amount (length) of neck sized (e.g. you can size only half the neck).
12. Interior diameter of bushing, or neck section of non-bushing die.

– and there are others…

One needs to understand that bushing size isn’t the beginning and end of neck tension questions, because, even if bushing size is held constant, the amount of bullet “grip” can change dramatically as the condition of your brass changes. Bullet “grip” can also change if you alter your seating depth, and it can even change if you ultrasonically clean your cases.

6-time U.S. National Long-Range Champion John Whidden adds: “Our tests show us that the condition of the necks in regards to lubed or not, carbon inside or not, squeaky clean or not, etc., matter even more than the size of the bushing used. An ultrasonically cleaned or brand new dry case neck make for some quite high seating force.”

Redding neck bushingsIn our Shooters’ Forum a reader asked: “How much neck tension should I use?” This prompted a lengthy Forum discussion in which other Forum members recommended a specific number based on their experience, such as .001″, .002″, or .003″. These numbers, as commonly used, correspond to the difference between case-neck OD after sizing and the neck OD of a loaded round, with bullet in place. In other words, the numbers refer to the nominal amount of interference fit (after sizing).

While these commonly-used “tension numbers” (of .001″, .002″ etc.) can be useful as starting points, neck tension is actually a fairly complex subject. The actual amount of “grip” on the bullet is a function of many factors, of which neck-OD reduction during sizing is just one. Understanding these many factors will help you maintain consistent neck tension as your brass “evolves” over the course of multiple reloadings.

Seating Depth Changes Can Increase or Decrease Grip on Bullet
You can do this simple experiment. Seat a boat-tail bullet in your sized neck with .150″ of bearing surface (shank) in the neck. Now remove the bullet with an impact hammer. Next, take another identical bullet and seat it with .300″ of bearing surface in another sized case (same bushing size/same nominal tension). You’ll find the deeper-seated bullet is gripped much harder.

PPC lapua brassNeck-Wall Thickness is Important Too
I have also found that thinner necks, particularly the very thin necks used by many 6mm PPC benchrest shooters, require more sizing to give equivalent “grip”. Again, do your own experiment. Seat a bullet in a case turned to .008″ neckwall thickness and sized down .003″. Now compare that to a case with .014″ neckwall thickness and sized down .0015″. You may find that the bullet in the thin necks actually pulls out easier, though it supposedly has more “neck tension”, if one were to consider bushing size alone.

In practical terms, because thick necks are less elastic than very thin necks, when you turn necks you may need to run tighter bushings to maintain the same amount of actual grip on the bullets (as compared to no-turn brass). Consequently, I suspect the guys using .0015″ “tension” on no-turn brass may be a lot closer to the guys using .003″ “tension” on turned necks than either group may realize.

Toward a Better Definition of Neck Tension
As a convenient short-cut, we tend to describe neck tension by bushing size alone. When a guy says, “I run .002 neck tension”, that normally means he is using a die/bushing that sizes the necks .002″ smaller than a loaded round. Well we know something about his post-sizing neck OD, but do we really have a reliable idea about how much force is required to release his bullets? Maybe not… This use of the term “neck tension” when we are really only describing the amount of neck diameter reduction with a die/bushing is really kind of incomplete.

My point here is that it is overly simplistic to ask, “should I load with .001 tension or .003?” In reality, an .001″ reduction (after springback) on a thick neck might provide MORE “grip” on a deep-seated bullet than an .003″ reduction on a very thin-walled neck holding a bullet with minimal bearing surface in the neck. Bushing ID is something we can easily measure and verify. We use bushing size as a descriptor of neck tension because it is convenient and because the other important factors are hard to quantify. But those factors shouldn’t be ignored if you want to maintain consistent neck tension for optimal accuracy.

Consistency and accuracy — that’s really what this all about isn’t it? We want to find the best neck tension for accuracy, and then maintain that amount of grip-on-bullet over time. To do that you need to look not only at your bushing size, but also at how your brass has changed (work-hardened) with time, and whether other variables (such as the amount of carbon in the neck) have changed. Ultimately, optimal neck tension must be ascertained experimentally. You have to go out and test empirically to see what works, in YOUR rifle, with YOUR bullets and YOUR brass. And you may have to change the nominal tension setting (i.e. bushing size) as your brass work-hardens or IF YOU CHANGE SEATING DEPTHS.

Remember that bushing size alone does not tell us all we need to know about the neck’s true “holding power” on a bullet, or the energy required for bullet release. True bullet grip is a more complicated phenomenon, one that is affected by numerous factors, some of which are very hard to quantify.

Good Online Guide to Basics of Rifle Cartridge Reloading

cartridge reloading reload step instruction manual high pressure signs

The Shooting Sports USA website includes two excellent articles about the basics of metallic cartridge reloading. These two articles provide an excellent summary of the key procedures. If you are new to reloading, we recommend you read both articles:

Introduction to Metallic Cartridge Reloading Part I »

Introduction to Metallic Cartridge Reloading Part II »

Part II is particularly helpful because it explains the entire reloading process step-by-step, with 14 listed steps. The author notes: “In this, the second installment on metallic cartridge reloading, we’ll follow the sequence of steps involved in reloading a rifle cartridge and refining a metallic cartridge load. These steps are based on the use of a single-stage reloading press and a separate priming tool.”

Much important advice is provided as this article runs through the 14 Steps of Reloading. For example, when explaining Step 13, Bullet Seating, the article states:

“Proper seating depth is critical. Too much bullet protrusion and the cartridge may not work through the gun’s magazine, or it may fail to chamber. Too little and the bullet intrudes excessively into the powder chamber, decreasing volume and raising pressure. Neck tension is also important; any bullet that fails to seat with some resistance may be held only loosely by the neck and may be driven back into the case when the round is chambered, especially in semi-automatic arms.”

Important Guide to Detecting Over-Pressure Signs in Brass
As an example of the invaluable advice provided in these two articles, here’s a sample from Part II that explains how to determine if your load is over-pressure. We recommend that EVERY reader read this twice. There are more things to consider than a stiff bolt lift. You need to inspect cartridges very carefully:

MDT Introduces 1.7 oz. Titanium Muzzle Brake for Hunting Rifles

MDT titanium 1.7 ounce hunt hunting muzzle brake

Here is an interesting item for hunters who want to keep their rifle as light as possible. MDT has introduced a new Titanium muzzle brake that weighs just 1.7 ounces. This ultralight MDT Hunt Brake can reduce recoil, so it’s a definite help for heavier calibers. And by reducing recoil up to 66% the follow-up shot speed is greatly improved. The new MDT Hunt brake has upward venting ports to reduce muzzle rise also (see video below at 1:05 time-mark).

On the negative side, the muzzle brake will increase noise heard by the hunter and can kick up dust if the shooter is firing from the ground. That can give away a hunter’s position, potentially spooking his prey.

Still, many hunters may want a modern brake, and this new $249.95 MDT Hunt Brake has some impressive design features. The baffles are designed to mitigate recoil and keep the shooter on target, and the self-timing lock makes installation easy. The MDT Hunt Brake is the third in MDT’s muzzle brake series which includes the steel Elite Brake ($129.95) and the innovative MDT Comp brake ($249.95), which has tunable upward gas vents and directs the blast away from the shooter.

MDT titanium 1.7 ounce hunt hunting muzzle brake

Key Features of the MDT Titanium HUNT BRAKE:

Titanium Construction — Hunt Brake Weighs just 1.7 ounces
4 Baffle design to mitigate recoil and muzzle climb
The design also reduces backwards muzzle blast
Designed to match Sendero profile barrels
Self-timing nut for easy installation
Size specification options:
6.5/7mm/308 – 1/2-28
6.5/7mm/308 – 5/8-24
.338 – 5/8-24

Good Wind-Reading Resource — The Wind Book for Rifle Shooters

wind reading book Camp Perry Miller Cunningham

“The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.” — William Arthur Ward

Readers often ask us: “Is there a decent, easy-to-comprehend book that can help my wind-reading?” Many of our Forum members have recommended The Wind Book for Rifle Shooters by Linda Miller and Keith Cunningham.

New Edition — Hardback and eBook
The latest, updated edition of The Wind Book for Rifle Shooters was released in May 2020. This 144-page book, first published in 2007, is a great resource. But you don’t have to take our word for it. If you click this link, you can read book excerpts and decide for yourself. When the Amazon page opens, look below the book cover photo, and click the bar labeled “Read Sample”. This lets you preview chapters from the Wind Book, and view some illustrations. Along with the hardback edition ($22.99), Amazon offers a Kindle (eBook) edition for $14.99.

Other books cover wind reading in a broader discussion of ballistics or long-range shooting, such as Applied Ballistics for Long-Range Shooting by Bryan Litz. But the Miller & Cunningham book is ALL about wind reading from cover to cover, and that is its strength. The book focuses on real world skills that can help you accurately gauge wind angle, wind velocity, and wind cycles.

All other factors being equal, it is your ability to read the wind that will make the most difference in your shooting accuracy. The better you understand the behavior of the wind, the better you will understand the behavior of your bullet. — The Wind Book for Rifle Shooters

The Wind Book for Rifle Shooters covers techniques and tactics used by expert wind-readers. There are numerous charts and illustrations. The authors show you how to put together a simple wind-reading “toolbox” for calculating wind speed, direction, deflection and drift. Then they explain how to use these tools to read flags and mirage, record and interpret your observations, and time your shots to compensate for wind.

I believe this is a must-have book if you are a long-range sport shooter. I compete in F-Class Open and when I first purchased this book and read it from cover to cover, it helped me understand wind reading and making accurate scope corrections. Buy this book, read it, put into practice what it tells you, you will not be disappointed. — P. Janzso

If you have one book for wind reading, this should be it. Whether you’re a novice or experienced wind shooter this book has something for you. It covers how to get wind speed and direction from flags, mirage, and natural phenomenon. In my opinion this is the best book for learning to read wind speed and direction. — Muddler

RMAC Rocky Mountain Airgun Challenge on ShootingUSA TV

Shooting USA TV Rocky Mountain Air-gun Challenge Provo Utah

rmac rocky mountain airgun utah  precisionShooting USA TV has a good show released today. Shooting USA’s Wednesday Night episode features RMAC — the Rocky Mountain Airgun Challenge. This is a fun and challenging, multi-class tactical-style airgun competition.

The RMAC event, hosted by Utah Airguns, is one of the largest outdoor air rifle matches in the country. It combines the low-cost of air rifle shooting with the fun of PRS/NRL-type multi-stage shooting.

Shooting USA SHOW TIMES: This Shooting USA Episode airs Wednesday, Jan. 29, 2025 at 9:00 PM Eastern and Pacific; 8:00 PM Central. If you miss the regular broadcast, you can stream the show online at any time on Vimeo for $0.99 per episode.

The Rocky Mountain Airgun Challenge

Shooting USA TV Rocky Mountain Air-gun Challenge Provo Utah

The 2024 Rocky Mountain Airgun Challenge in Provo, Utah attracted top shooters with over $100,000 worth of prizes. The stages look like what you’d see at PRS/NRL events, but the targets are smaller, the range is shorter, and the power behind each shot is air. Practical Air-Gun competition has a well-established community that spans the globe, and recently competitors from other shooting disciplines, the powder burners, beginning to take notice. Air-Gun practical competition is fun and inexpensive — you are paying pennies a round vs. a $1.30 or more per round for premium centerfire ammo. The Rocky Mountain Airgun Challenge is leading the way in this interesting air-powered shooting discipline. This multi-day event featured a variety of events on multiple stages.

Modern Tactical-Style Air Rifles

Here are two state-of-the-art tactical air rifles, the BinTac MCAR ($2790.00 from Airgun Tactical) and the FX IMPACT M4 ($2099.99 from Utah Airguns). The BinTac MCAR almost looks like a centerfire rifle at first glance but the air chambers on the buttstock tell the real story.

Organize Long Guns in Safe with Handy Rifle Rods

Gun Storage Solutions Rifle Rod Kit

Running out of space in your gun safe? Here’s a clever product that will allow you to store more long guns in your current vault. The plastic Rifle Rods from Gun Storage Solutions slip in long-gun barrels and then grip the shelf above using Velcro pads. This allows you to nestle your rifles and shotguns much closer together than with the conventional racks provided with most gunsafes.

The handy Rifle Rods are offered in bright orange or basic black. We prefer the orange rods (shown above with the Velcro “receiver” shelf liner provided with the Rod Kit).

Gun Storage Solutions Rifle Rod Kit

Rifles with narrow furniture (such as lever guns) can be placed very close together, saving lots of space. For benchrest or varmint rifles with wider fore-ends, you won’t benefit as much. Note that, in the photo above, all of the guns are fairly slim — none have wide fore-ends. Still we think these Rifle Rods could open up 12″ or more horizontal clearance in a medium-sized safe — that could easily allow you to store six (6) more guns in two rows, as shown.

Rifle Rod Kits Starting at $20.70
A kit with 5 Rifle Rods and loop fabric shelf liner costs $20.70 on Amazon.com, while the 10-Rod Kit with liner costs $33.29 this week. That’s a lot cheaper than buying a new safe. A six-pack of additional Rifle Rods costs $17.95 on Amazon. You can also purchases rods and fabric directly from Gun Storage Solutions.

WARNING: Always REMOVE Rod from barrel before taking gun to the range. Never place live ammunition in a gun with storage Rod in the barrel!

New $2600 CZ Pistol for Pistol Matches — Accuracy at a Price

cz pistol shadow 2 target competition IPSC 2024 9mm 9x19mm

New CZ Shadow 2 Target Pistol — Great for Gun Games
The new CZ Shadow 2 Target pistol has attracted much attention, with some very positive reviews. The Firearm Blog says the new Shadow 2 Target may be the most accurate CZ pistol ever made. But with a steep $2599.99 MSRP it better be good! If you compete in action pistol matches, the CZ Shadow 2 Target could take you to the next level… but that price could be a deal-breaker for many. Here are two recent video reviews of this impressive new pistol. CLICK HERE for more photos and full specifications.

In the video below GunsAmerica Digest Editor True Pearce reviews the new CZ Shadow 2 Target pistol. This 9mm pistol features an extended slide, 6-inch polished and hand-fitted barrel, full steel frame, and handsome ergonomic grip. This pistol also boasts a very crisp trigger that can adjust to five positions.

The regular Shadow 2 has won many IPSC world championships. And this new Shadow 2 Target model should be even better. The 6″ barrel and long slide offer significantly reduced muzzle lift for faster follow-up shots plus longer sight radius for more precise aiming. NOTE: As this pistol is designed for iron sights competition, the slide does NOT have an “optics cut” to take the larger red dot optics.

SIGHT TALK — Eye Dominance, Vision Protection, Irons vs. Optics

firearm science NRA Jessie Duff Harrison

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.

Bullet-Making — Videos Show How Barnes Bullets Are Made

Barnes Bullets Factory

Barnes Bullets FactoryMany of our readers have been interested in learning how modern bullets are made. While a “boutique” bullet-maker, supplied with appropriate cores and jackets, can craft bullets using relatively simple hand dies and manual presses, factory production is different. The major bullet-makers, such as Barnes, employ huge, complex machines to craft their projectiles on an assembly line.

Modern hunting bullets are made with a variety of sophisticated (and expensive) machines, such as Computer Numerical Control (CNC) lathes, giant multi-stage presses, and hydraulic extruding machines that draw lead ingots into lead wire. Barnes offers an “inside look” at the bullet production process in a series of videos filmed at its Mona, UT factory. We’ve embedded four videos from the series here. These videos can also be viewed on the Barnes Bullets YouTube Channel.

Milling Slots in TSX All-Copper Bullet
This video shows how the slots (between the drive bands) in the TSX all-copper bullet are cut. The slots reduce the bearing surface that contacts the rifling. This helps reduce friction and heat, extending the life of barrels used with all-metal, drive-band bullets:

Varminator Bullets Produced in Jumbo Transfer Press
Here is the transfer press used in the production of Varminator and MPG Bullets. The process begins with a giant spool of flat copper material. The copper is stamped into jackets and eventually the formed Varminator bullets are ejected one by one into a bucket.

CNC Lathe Turns Bullets Automatically
In the video below, a Bar-Feed CNC crafts mono-bloc bullets from metal bar stock. Barnes uses a small CNC lathe to turn .50-caliber bullets from brass bar stock. We’re not sure which bullet is being made in this video. The material looks to be sintered metal. In the close-ups you can gold-colored shavings from when the machine was previously used for CNC-turned brass bullets.

Accuracy Testing in 100-yard Tunnel
Barnes regularly tests bullet samples for accuracy. In the video below, a Barnes technician loads sample rounds and tests them for accuracy in a 100-yard tunnel. The rounds are shot through a special fixture — basically a barreled action connected to parallel rods on either side. This allows the testing fixture to slide straight back on recoil (see it move back at 1:07-08 minute mark).

Upside-Down Trigger — Application for Unlimited Benchrest Competition?
Note how the tester actuates the trigger, which points UPWARDS, just the opposite of a normal rifle. The technician lightly taps the upward-pointing trigger shoe with a metal rod. Could this upside-down trigger work in benchrest shooting — perhaps with railguns? It could make for an interesting experiment.
