When neck-turning cases, it’s a good idea to extend the cut slightly below the neck-shoulder junction. This helps keep neck tension more uniform after repeated firings, by preventing a build-up of brass where the neck meets the shoulder. One of our Forum members, Craig from Ireland, a self-declared “neck-turning novice”, was having some problems turning brass for his 20 Tactical cases. He was correctly attempting to continue the cut slightly past the neck-shoulder junction, but he was concerned that brass was being removed too far down the shoulder.
Craig writes: “Everywhere I have read about neck turning, [it says] you need to cut slightly into the neck/shoulder junction to stop doughnutting. I completely understand this but I cant seem to get my neck-turning tool set-up to just touch the neck/shoulder junction. It either just doesn’t touch [the shoulder] or cuts nearly the whole shoulder and that just looks very messy. No matter how I adjust the mandrel to set how far down the neck it cuts, it either doesn’t touch it or it cuts far too much. I think it may relate to the bevel on the cutter in my neck-turning tool…”
Looking at Craig’s pictures, we’d agree that he didn’t need to cut so far down into the shoulder. There is a simple solution for this situation. Craig is using a neck-turning tool with a rather shallow cutter bevel angle. This 20-degree angle is set up as “universal geometry” that will work with any shoulder angle. Unfortunately, as you work the cutter down the neck, a shallow angled-cutter tip such as this will remove brass fairly far down. You only want to extend the cut about 1/32 of an inch past the neck-shoulder junction. This is enough to eliminate brass build-up at the base of the neck that can cause doughnuts to form.
The answer here is simply to use a cutter tip with a wider angle — 30 to 40 degrees. The cutter for the K&M neck-turning tool (above) has a shorter bevel that better matches a 30° shoulder. There is also a 40° tip available. PMA Tool and 21st Century Shooting also offer carbide cutters with a variety of bevel angles to exactly match your case shoulder angle*. WalkerTexasRanger reports: “I went to a 40-degree cutter head just to address this same issue, and I have been much happier with the results. The 40-degree heads are available from Sinclair Int’l for $15 or so.” Forum Member CBonner concurs: “I had the same problem with my 7WSM… The 40-degree cutter was the answer.” Below is Sinclair’s 40° Cutter for its NT-series neck-turning tools. Item NT3140, this 40° Cutter sells for $14.99. For the same price, Sinclair also sells the conventional 30° Cutter, item NT3100.
Al Nyhus has another clever solution: “The best way I’ve found to get around this problem is to get an extra shell holder and face it off .020-.025 and then run the cases into the sizing die. This will push the shoulder back .020-.025. Then you neck turn down to the ‘new’ neck/shoulder junction and simply stop there. Fireforming the cases by seating the bullets hard into the lands will blow the shoulder forward and the extra neck length you turned by having the shoulder set back will now be blended perfectly into the shoulder. The results are a case that perfectly fits the chamber and zero donuts.”
Today’s video showcase covers bore-sighting methods and technology. Bore-sighting the old-fashioned way — by looking down the bore of a rifle at a target — is not difficult. With a conventional bolt-action rifle, visual bore-sighting can be done quickly and easily. Rest your gun securely on bags, remove your bolt and set up a 50-yard target with a large bright orange or black center circle. Look through the back of the action and you should be able to sight down the bore with your own eyes just fine. There’s no need for expensive hardware. In fact it may be easier to bore-sight the “old-fashioned way” rather than try to see a laser in bright sunlight at 50 yards (or even 25).
However, with lever guns and semi-auto rifles, including the popular AR15, M1 Garand, and M1A, the design of the receiver may make it virtually impossible to sight down the bore with the naked eye. That’s where a modern laser bore-sighting device comes in handy. For those situations where a bore-sighting tool is needed, we recommend a laser bore-sighter that fits inside your chamber. An in-chamber laser device, as shown below, is handy and has less safety risk than a tool which fits in the end of the barrel.
How to Bore-Sight Your Rifle in Five Minutes
This video from Australia shows the basics of the bore-sighting process. First set up a target 50 yards (or closer) from your shooting station. Make sure the rifle is well-supported and stable. When the target is ideally centered in the BORE of the barrel, then adjust the reticle on your scope to center the crosshairs on the middle of the target. Then, after checking down-range, take a few test shots. Finally, move the target out to 100 yards and confirm your zero, as explained at the close of today’s article.
Vortex Shows How to Bore-Sight Rifles
This well-made, informative video from Vortex covers the basics of bore-sighting. Bore sighting your rifle is a simple way to establish an initial zero to get you on target faster and save you ammo at the range. Thankfully, it doesn’t take a ton of gear or ammunition to bore-sight a rifle effectively. Video host Jimmy from Vortex provides a handy, step-by-step guide in this 10-minute video.
Bore-Sighting Using a Barrel-Mounted Laser Bore-Sighter
If you wondered why a barrel-mounted laser bore-sighter was off-center? Or if you want to learn how to use one properly, this video shows how to safely and properly zero a scope using a barrel-mounted laser bore sight device. Another option is a small cartridge-sized laser that fits inside the chamber. These sell for under $25.00 and are convenient. There are safety advantages to in-chamber lasers.
Initial Bore-Sighting at Home (Before You Head to the Range)
This useful video shows how to bore-sight a rifle at home. This can save time (and money for ammo) when you do get to the range to confirm your scope’s zero. This home procedure works best if the target is well-illuminated while the rifle is in a shadowed area, creating the best contrast. Also make sure the rifle is on a steady support — such as a portable gun vise or sandbags front and rear.
Bore-Sighting with a Red Dot (Reflex) Sight
As with conventional scopes, if you have a red dot sight or reflex optic, you’ll need to bore-sight your rifle, then zero the optic. [Reflex sights use a reflex lens to project a dot or reticle onto the target, whereas red dot sights use a flat, reflective surface to display a red dot reticle.] In this video, retired Navy SEAL Mark Cochiolo demonstrates how to bore-sight then adjust a red dot. Bore sighting allows you to zero your red dot so that your shots hit near your intended point of impact.
Learn More about Bore-Sighting with Tools
To learn more about bore-sighting, you can view a detailed article on the Warne Scope Mounts website. This features through-the-barrel images and discussion of tools that fit in the chamber or barrel to project a laser beam down-range. Shown below are cartridge-sized projecting lasers that fit in a rifle’s chamber. These are available for a wide variety of cartridge/chamber sizes.
WARNING: If you use an in-barrel laser be sure to remove it BEFORE chambering a round. ANY obstruction in the barrel can cause serious injury or even death if you fire a round.
Bore Sight Grid Tool with Arbors
The Bushnell Bore Sight with Arbors is a bore-sighting tool that many gun stores and gunsmiths use. This device uses arbors but does not transmit a laser.
You attach the tool to the end of the barrel and align it with your scope. A grid is visible inside the bore-sighter. Look at that grid and then and align your scope’s reticle with the grid. This Bushnell unit ships with three expandable arbors in 22-270 caliber, 7mm-35 caliber, and 35-45 caliber.
How to Zero a Hunting Rifle Efficiently
Once you have bore-sighted your rifle to get “on target” successfully, then you want to zero your optic so that the shot falls exactly where you want it at your target distance, typically 100 yards. This Vortex video shows you how to quickly and efficiently sight-in and zero a hunting rifle before heading out into the field. This video explains a simple procedure that lets you get a solid zero in just three shots. Of course you probably want to fire a few more rounds to confirm your zero before you head off to your hunting grounds, but this will let you get on-target with a minimum amount of time and ammo expended. This helpful video now has 3.2 million views on YouTube!
Fouling Shots and Cold Bore Condition
If you recently cleaned your rifle, you may want to fire two or three fouling shots before you start this procedure. But keep in mind that you want to duplicate the typical cold bore conditions that you’ll experience during the hunt. If you set your zero after three fouling shots, then make sure the bore is in a similar condition when you actually go out hunting.

Now through Sunday, July 30th, 2023, classic military rifles will fill the firing lines at Camp Perry. The National John C. Garand, Springfield, Vintage and Modern Military Match (GSMM) commenced on the 26th, and will run through this upcoming Sunday the 30th, with the one-day Springfield M1A Match on Sunday only. (See CMP Camp Perry 2023 Calendar.) Some participants will shoot just one rifle type, but there is also a combined GSMM 4-Gun Aggregate. This GSSM Agg encompasses a series of position shooting matches on NRA SR targets at the CMP Nationals. As the matches are completed, day by day, results will be posted on the CMP National Matches Results Page.
This video shows the Garand Match at Camp Perry. The rifles are still the same a decade later…
The annual GSMM event is one of the most popular events at Camp Perry, drawing participants from around the nation. One of America’s top GSSM shooters is Brian Williams, who was profiled in our Daily Bulletin. The 4-gun Aggregate includes Garand, 1903 Springfield/1917 Enfield (or similar bolt rifle), M1 Carbine, and AR-type rifle for “Modern Military”. Remarkably, Brian has won the GSMM 4-Gun at the CMP National Matches in Camp Perry three years in a row — the inaugural 2017 4-Gun Agg, plus 2018 and 2019. Below, Brian offers some thoughts on the classic wood-stocked rifles used in GSMM competition.
The Classic Wood Guns of CMP 4-Gun Competition
Perspectives on M1 Garand, M1903A3, M1917, and M1 Carbine
Brian provides perspectives on the “Wood Gun” game, with suggestions on how to improve your performance with the M1 Garand, M1903 Springfield, M1917 Enfield, M1 Carbine, and other 20th Century military rifles. Brian explains what to look for
Q: What should one look for when acquiring older rifles for CMP 4-Gun Games — M1 Garand, M1903/1903A3, M1917, M1 Carbine? What are realistic budgets for these firearms? What kind of accuracy can one expect? What upgrades are important?
Brian: All of these military surplus rifles are out there, but they are getting harder to get your hands on. And, just like everything else, the prices continue to rise. Not that long ago you could get your hands on a M1 Garand for four or five hundred dollars. In today’s market they are usually about double that price. But understand that these rifles are all unique and all have a story to tell. No two are alike, or have the same story. Just like the guns themselves, there are fewer and fewer dedicated gunsmiths for these vintage rifles. But I promise if you look for a good smith, they are out there and they are some of the most interesting people you will ever meet.
M1 Garand — Of the four (4) centerfire guns I shoot in the CMP games, my favorite has to be the M1 Garand. There were over 6 million of them produced in a very short time period, and every single one has its own unique story, and that is just cool. M1 Garands are capable of good accuracy. I believe that a well-maintained M1 with at least a replacement barrel is capable of shooting between 1 and 1.5 MOA.
M1903A3 Springfield — I find that the sights on a M1903A3 are a little easier to see than the sights of the M1903, but both are very accurate rifles. Like most military rifles in the current climate the prices have risen dramatically, but there are some gems out there that can be had for far less than $1000. The nice thing about the Springfield rifle is that almost all of the accuracy than you would want can come from just replacing a worn out 80-year-old barrel. In terms of accuracy, I think a good M1903A3 can shoot 1 MOA most of the time.
M1917 Enfield — This rifle is the newest of my collection and it shoots very well, with just a new Criterion barrel — again about 1 MOA with iron sights. These rifles are very close in price to the M1903 Springfield. But if you do your homework and keep your eyes open, there are always great deals to be found. I actually prefer shooting the M1917 to my M1903A3, due primarily to the M1917’s cock-on-close bolt which allows smoother cycling.

M1 Carbine — By 1945 there had been more M1 Carbines built than Garands. Today the Carbine can be harder to find, and due to the scarcity the price has shot up and most military M1 Carbines are going for more than $1000 at this point. The great thing about the M1 Carbine is that as long as you have a good ammo supply this rifle can shoot. Honest. I have had countless numbers of people that tell me that there is not an M1 carbine that will shoot. I can tell you from experience that they will, but you are going to have to put in some time with one to learn how to get it to shoot where you want it.
The M1 Carbine shoots the .30 Carbine round, with 110gr bullet going about 1990 FPS. In comparison, the .30-06 Springfield round used in the M1 Garand is almost three times more powerful than the .30 Carbine.
After purchasing a new set of dies from Forster, Hornady, Redding, or Whidden Gunworks, you’ll want to disassemble the dies, inspect then, and then remove the internal grease and/or waxy coatings placed on the dies by the manufacturer. Below are two videos that show how to de-grease and clean dies as they come “out of the box” from the manufacturer. The videos also explain how to clean your dies after regular use. Cleaning your dies helps remove carbon, brass shavings, lube residues and other stuff that can get inside the dies.
In the first video, from Creedmoor Sports, Bill Gravatt (Creedmoor’s President) shows various methods for cleaning dies both when new and after they have accumulated carbon and lube after use. This video is definitely worth watching. In the second video, a Hornady technician shows the method for degreasing dies before first use. A convenient aerosol spray cleaner is used in the video. You can also use a liquid solvent with soft nylon brush, and cotton patches. NOTE: After cleaning you may want to apply a light grease to the external threads of your dies.

Clean Your Sizing Dies and Body Dies Regularly
These same techniques work for cleaning dies after they have been used for reloading. Many otherwise smart hand-loaders forget to clean the inside of their dies, allowing old case lube, gunk, carbon residue, and other contaminants to build up inside the die. You should clean your dies fairly often, particularly if you do not tumble or ultrasound your cases between loadings. It is most important to keep full-length sizing and body dies clean. These dies accumulate lube and carbon residue quickly.
Product Review by F-Class John
Case preparation is critical for precision reloading. One must trim cases, debur/chamfer case mouths, clean necks, spruce up primer pockets and do other important tasks. Complete case prep can involve many separate processes, each requiring its own tools. With each of those tools comes additional cost as well as the need for more storage and bench space. To make case prep easier, faster, and more convenient Lyman created the Case Prep Xpress (#ad). The Case Prep Xpress, introduced a few years back, combines up to five prep stages into one well-built, stable, versatile unit. Watch this video to see the machine in action:
The Case Prep Xpress features five (5) independently-turning spindles all with the common 8/32 thread. This allows you to attach multiple tools supplied with the unit PLUS many other screw-on prep tools. For our testing we started out using a variety of the 12 included tools and found they cover the majority of case prep tasks. Lyman supplies deburr and chamfer tools, pocket uniformers, reamers and cleaners, as well as an assortment of neck brushes.
The deburr and chamfer tools worked really well, creating beautiful bevels all while leaving a nice flat edge across the top of the neck which is critical for accuracy and brass life. We found the primer pocket cleaning tool did a good job, but for truly clean pockets we recommend using the primer pocket uniforming tool, which very efficiently removes even hard residues.
The benefit of having interchangeable heads is that you can add your own accessories. We like to use a bore brush with bronze wool wrapped around it for use inside our necks. This worked perfectly once we screwed it in. In fact, we couldn’t think of any 8/32-threaded accessory that wouldn’t work well on this machine. Another great design feature is how all the accessories are oriented straight up. This allows for perfect visual alignment of your cases onto the tools which is critical — especially when performing cutting operations such as primer pocket uniforming.
Along with the five power stations there are six female-threaded storage spots on the sides where tools can be placed to ensure they don’t get lost. We like this feature since there will be more than five accessories you want to use and having them easily available is a great feature. You can keep 11 tools right on the machine (5 on top, 6 on the sides). That way you don’t have to dig through storage bins.
The Case Prep Xpress has a removable front bin to hold brass shavings, and there are two circular trays on either side of the bin. In front is a long tray that holds the provided brush. This makes it relatively easy to clean off brass shavings and other debris from case prep processes.
SUMMARY — Versatile Case Prep Xpress Is A Good Value
For the money, Lyman’s Case Prep Xpress is tough to beat. It performs multiple tasks well while being stable and easy-to-use. Yes there are some multi-spindle prep centers that offer variable or fast/slow RPM spindles while the Lyman’s spindles are all fixed RPM. (See, e.g. the RCBS Brass Boss). However those other systems don’t include all the convenient on-board storage of the Case Prep Xpress, and are typically more expensive. The Lyman Case Prep Xpress sells for about $170-$190 “street price”. It’s currently on sale for $179.99 on Amazon (#ad). This makes the Lyman Case Prep Xpress a fine value — it offers great versatility while saving space and saving money compared to buying five or more separate, powered tools.

Report by Craig Arnzen, Area 419
As the PRS and other tactical/practical competitions continue to grow, a guy tends to wonder, just how good are the top competitors? And what are they actually doing (and viewing) as they complete a stage? Well, a great video from the Long Range Precision Shooters YouTube Channel let us see what the best in the sport see through their scopes when they shoot.
This video features Dave Preston, 2015 National Champion and consistent top performer, shooting the PRS Skills barricade. Dave Preston has been considered among the very best in the nation running this PRS stage. Dave nearly always shoots 100% with the fastest recorded time. In this video you’ll see him successfully engage all eight shots in under 43 seconds — that’s crazy fast. This includes a POV sequence (4:35 time-mark) showing the actual view through Dave’s scope as he completes the stage.
Watch this video! Dave offers excellent advice on gun-handling and body positioning for barricades. Listen to what he says and you WILL shoot better.
This video features the PRS Skills Barricade, an 8-round, 4-position stage featured at the majority of PRS matches throughout country. It’s called a “Skills Stage” as it is run the same way at every national match and gives shooters the ability to compare skill levels based on hit percentage and speed.
The target is a 10″ plate at 400 yards. There are four different positions, with two shots each. Most people run this stage in about 70 seconds, some in the mid-60s, the greats in the high 50s, and Dave does it in the low 40s… mighty impressive!
The Right Gear Aids Stability and Lets You Shoot Faster
Let’s also take a look at two pieces of gear that really helped Dave Preston get stable and shoot fast.
1. BARRICADE BAG — To Get Stable, Really Stable
In the video Dave is using a Solo Sac from Short Action Precision This bag was designed by USMC Solomon Mansalala. It’s a very soft/dense bag and is popular at matches.
The other bag that sees a LOT of use, and is far and away the most used, is the patented Gamechanger Bag from Reasor Precision Solutions and Armageddon Gear.
2. MUZZLE BRAKE — To Make Your Follow-Up Faster
You’ll notice that in the video the rifle is very steady through firing, even though he is not applying a lot of pressure to the rifle. Dave is using a Hellfire Muzzle Brake from Area 419. Combined with the soft-recoiling 6mmBR cartridge he is able to spot his impacts and make adjustments, and can also make very fast follow-up shots as his rifle hasn’t bounced way off target.
What can happen when the bottom-most primer in a primer feed tube goes off? A big bang, that’s what. Some or all of the primers in the vertical feeding tube can go off in a chain detonation. That’s exactly what happened to Dustin Ellermann, Top Shot Season 3 Champion. Scary experience, but thankfully Dustin was not injured. He writes: “Super thankful that I was wearing my Wiley X eye protection this weekend when I was reloading some .223 rounds. My press detonated nearly 100 small rifle primers. Shown here is the magazine feed tube. Not fun but it could have been much worse. Stay safe!”
When working with progressive reloading presses, you should definitely wear eye protection. Dustin’s chain detonation experience proves that — without a doubt. Remember you only have one set of eyes!
RCBS APS Strips — Alternative to Primer Tubes When you stack a column of primers in a single metal tube, you’re asking for trouble. As Dustin Ellermann learned, when one primer fires, the entire column can follow suit in a chain detonation. Thankfully, you do have options when it comes to primer feeding on a progressive press. RCBS developed an innovative, smart system with primers in horizontal plastic strips. Instead of being stored in a vertical tube, primers are placed in flat, plastic “APS” strips, with a ring of plastic separating each primer. Moving horizontally, primers are never stacked, so the chance of a chain detonation is reduced dramatically. The re-usable APS strips are color-coded for different primer types. You can buy CCI “pre-loaded” primer strips, or you can insert any brand of primers into strips using an RCBS strip-loader tool.
RCBS APS Strip Priming System This video shows how to use APS primer strips wiht a bench-mounted priming system.
AccurateShooter.com Editor Uses Strip Primers
This Editor owns an RCBS Pro-2000 progressive press. The RCBS strip-priming system was one key reason I selected the RCBS Pro-2000 over similar-priced progressives from Dillon and Hornady. I believe the strip primer system is safer, more positive, and easier to use. Before I purchased my RCBS progressive, I “road-tested” the competition. I loaded hundreds of rounds on each of four different progressives: Dillon 550B, Dillon 650, Hornady Lock-N-Load, and RCBS 2000. I was concerned about the primer feed tubes on the Dillons, and I found the RCBS rotary powder measure was much more precise (and easier to adjust) than the sliding bar system on the Dillon machines. The RCBS priming system was definitely more fool-proof than the system on the Hornady press (a first-generation L-N-L that had issues with primer feeding). After “test-driving” blue, red, and green brand progressives extensively, I settled on the RCBS Pro-2000. A decade later, I still think I made the right choice. I like the APS strips for big jobs, and I can also use them in the RCBS hand-priming tool (shown below). With the strips, it’s easy to prime 20 or 40 cases at a time, and then switch to another type of primer for comparison testing.
NOTE: Unfortunately, most of the RCBS APS system tools are no longer in production. But the tools and strips are still available on eBay and many reloading Forums, in some cases “new in box”. This Editor’s APS hand priming tool is still working great after 15 years.
The APS priming system also works with press-mounted priming tool, bench-mounted tool, and APS hand-tool. EdLongRange uses the press-mounted tool: “I also like the APS approach but use the press-mounted unit (saves your hands/wrists — and I haven’t had a need for a progressive press in over 20 years). Loading the primers in the strips is a bit of a PITA but very manageable. As with all tools there is a learning curve.” CLICK HERE for video showing strip-loading tool and press-mounted APS tool. The RCBS press-mounted tool is no longer in production by RCBS, but you can still find it in some stores or on eBay.
Here’s a simple task you can do that will give your seater die a more perfect fit to your match bullets. You can lap the inside of the seater stem so that it matches the exact profile of the bullet. This spreads out the seating force over a larger area of the bullet jacket. That allows smoother, more consistent seating, without putting dents, creases, or sharp rings in your bullets.
This process is demonstrated here by our friend Erik Cortina of Team Lapua-Brux-Borden. Erik, one of the nation’s top F-Class shooters and a skilled machinist, explains: “Here I’m lapping my new seater die stem with lapping compound. I chuck up a bullet in the lathe and lap the inside of the seating stem. I put lapping compound on the bullet and also in the stem. You can do the same with a hand drill and bore paste. You can see in the piture below how much contact area the stem has on the bullet after being lapped. This bullet is a Berger 7mm 180-grain Hybrid. ”
It can be helpful but it’s not necessary to make your seating stem an exact match to a bullet, particularly if you’re loading hunting or varmint rounds. But it is helpful to do some mild internal stem polishing. This should eliminate any ring (or dent) that forms on the bullet jacket during seating.
Sharp edges on a seating stem can cause a ring to be pressed into the bullet jacket — especially with compressed loads that resist downward bullet movement.
Q2: Is there any down-side to the process?
Not really. However, if you shoot many different bullet types for a particular cartridge, you may not want to conform the stem aggressively to one particular bullet design. Lightly lap the inside of the stem to remove burrs/sharp edges but leave it at that. A light lap will prevent a ring forming when seating bullets.
When neck-turning cases, it’s a good idea to extend the cut slightly below the neck-shoulder junction. This helps keep neck tension more uniform after repeated firings, by preventing a build-up of brass where the neck meets the shoulder. One of our Forum members, Craig from Ireland, a self-declared “neck-turning novice”, was having some problems turning brass for his 20 Tactical cases. He was correctly attempting to continue the cut slightly past the neck-shoulder junction, but he was concerned that brass was being removed too far down the shoulder.
When you stack a column of primers in a single metal tube, you’re asking for trouble. As Dustin Ellermann learned, when one primer fires, the entire column can follow suit in a chain detonation.
