6.5 Creedmoor LOAD DATA Collection from Sierra Bullets

6.5 creedmoor load data sierra bullets

Sierra Bullets has released extensive load data for the popular 6.5 Creedmoor cartridge. This medium-sized cartridge has become one of the most popular chamberings for tactical and PRS shooters. The 6.5 Creedmoor combines excellent accuracy, good mag-feeding, good barrel life, moderate recoil, and reasonable component cost. That’s why this cartridge has caught on quickly, and is now one of the most popular chamberings in factory rifles.

Sierra Load Data 6.5 CreedmoorDeveloped in 2007 by Dennis DeMille and Dave Emary, the 6.5 Creedmoor is a shortened and improved 30 TC cartridge case that was inspired by the .308 Winchester design. This short action design was created to maximize case capacity and a wide range of loading lengths, while still fitting in standard short action magazines. With the correct twist barrel, the versatile 6.5 Creedmoor can take advantage of the wide range of bullet weights available in 6.5 mm (i.e. .264 caliber). Reloaders should keep in mind that the 6.5 Creedmoor works best with medium to medium-slow powders such as H4350, Varget, Win 760, and RE-17. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power, precision rifle series and benchrest competitions. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success which should insure its legacy for decades to come.

Here are three tables from the Sierra Bullets Reloading Manual (5th Edition). IMPORTANT — This is just a sample!! Sierra has load data for many other 6.5mm bullet types, including FB, Spitzer, SBT, HPBT, and Tipped MK from 85 grains to 142 grains. To view ALL 6.5 Creedmoor DATA, CLICK HERE.

Saturday at the Movies: Six Notable Ultimate Reloader Videos

Ultimate reloader gavin gear longshot camera AMP press anschutz rifle 7mm PRC 6.5 PRC 300 muzzle brake videos

UltimateReloader.com offers some of the most thorough firearms and reloading tool tests on the internet. And UltimateReloader’s YouTube Channel has hundreds of great videos that showcase reloading tools, accurate firearms, precision optics, gunsmithing methods, and top-tier reloading components. For today’s Saturday at the Movies feature, we showcase six great videos recently created by Gavin Gear and his UltimateReloader team. These videos highlight a superb Long-Range Target Camera, the remarkable AMP Press, the new Hornady PRC cartridges, and other interesting topics. On this final day of 2022, enjoy our Saturday Video Showcase.

With the high price of centerfire powders, bullets, and brass, everyone should have an accurate .22 LR rimfire rifle for marksmanship training and competition at 25 to 200 yards. In this video, Ultimate Reloader’s Gavin Gear tests the impressive Anschutz 54.18 BR50-U7 match rifle using a quality Sinclair Int’l front rest. Anschutz offers several versions of the 54.18 and BR-50. There are two barreled actions available: 20″ threaded and 25.9″ non-threaded. Gavin tested the 20″ threaded model with the U7 stock. In this video, Gavin tested the trigger with a sophisticated TriggerScan TS-11. The trigger was superbly repeatable at a measured 3.8 ounces. Gavin also did a bore examination. He then tested the Anschutz with a variety of premium ammo. In this rifle, Lapua Midas+ producing the smallest groups. FULL STORY HERE.

This video features the impressive, high-tech AMP Bullet Seating Press. The AMP Press combines a motor driven ram, a distance sensor, and a load cell to deliver extremely accurate and precise force/distance bullet seating measurements. The AMP Press offers unrivaled consistency in the bullet seating process. And as the AMP Press is linked to a computer, seating data can be stored and you can chart variations in seating resistance. A wealth of precise data is collected during the bullet seating process. This helps you optimize your brass prep and annealing for the best, most consistent results. FULL STORY HERE.

Past 400 yards or so, it can be difficult to see bullet holes on paper, even with spotting scopes. That’s why we recommend a high-quality wireless target camera. The best long-range target cameras on the market are produced by Longshot Camera Systems. The Longshot Target Cam provides a live WiFi camera feed. This comes back to your shooting station and you can view the image with a laptop or mobile device. You don’t need internet coverage and no separate tall antennas are required. Simply place the camera unit next to your target and the receiver unit close to your rifle or bench. The Longshot system is completely self-contained. Longshot produces a variety of cameras starting at $449.00 for the LongShot Marksman. We recommend the $899.00 LR-3 unit which works out to two miles! In this video Gavin Gear of UltimateReloader tests the LR-3 at long range. PRODUCT INFO HERE.

This video examines how muzzle brakes reduce recoil. Just how important is bore clearance for a muzzle brake? Should you have an exit diameter that’s just slightly larger than bullet diameter, or will a larger diameter work well also? Along with no brake at all (bare muzzle), Ultimate Reloader tested multiple different brake bore clearances on a 6.5 Creedmoor rifle: 0.010″ over bullet diameter, 0.020″, 0.030″, 0.050″, 0.100″, and 0.200″. The testers expected to get the best recoil reduction with the tightest fit. Surprisingly, this wasn’t quite the case.

Ultimate reloader gavin gear muzzle brake bore clearance video

Using all brake configurations (all bore clearances) Ultimate Reloader saw a significant reduction in recoil, almost half, as compared to a bare muzzle: “What we didn’t expect was how close together the rest of the clearances would cluster. All of the clearances that we tested had good recoil reduction.” FULL STORY HERE.

Dillon Precision continues to be the leader among progressive press makers. Dillon offers the largest variety of progressives, the most accessories, and legendary customer service. In this video, Gavin Gear of Ultimate Reloader looks at a variety of Dillon machines to help buyers decide which progressive best suits their needs. Featured Dillon progressives include: Square Deal B, Xl750, and RL1100. Along with basic press feature, Gavin shows the operation of Dillon’s automated bullet feeder and case feeder accessories. The video also provides pricing summaries with various configurations. FULL STORY HERE.

Hornady’s PRC (Precision Rifle Cartridge) family of cartridges are becoming quite popular. The 6.5 PRC fits in a short action, while the 7mm PRC and 300 PRC both require a long action. The 7mm PRC is a long-action centerfire hunting cartridge designed to shoot 180gr bullets at 2950+ FPS. The 6.5 PRC is a good hunting cartridge that can fit a standard-length action. And, a number of top F-Open shooters are necking up the 6.5 PRC for 7mm bullets. This 7-6.5 PRC wildcat has shown excellent F-Class accuracy with a higher velocity node than the .284 Winchester. Along with these two cartridges, Hornady has a 300 PRC that can shoot the big .308-caliber bullets. In this video, Ultimate Reloader analyzes and compares each of the three PRC cartridge types. FULL STORY HERE.

The World of Cartridges — Guide to Cartridge and Primer Types

pew pew tactical bullet cartridge photos rimfire primer illustration

The Pew Pew Tactical website has interesting article on rifle and pistol cartridges and bullet types. This contains a large selection of interesting photographs and illustrations. If you load and/or shoot for a wide variety of cartridge types, you’ll find that article well worth reading. It has nearly 50 photographs and more than a dozen short videos. READ FULL Article.

pew pew tactical bullet cartridge photos rimfire primer illustration

The article shows all types of pistol bullets, along with a variety of rifle projectiles. It even illustrates multiple types of shotshell cartridges.

The article also explains the basic components of modern cartridges –bullet, case, powder, and primer:

pew pew tactical bullet cartridge photos rimfire primer illustrationPopular Cartridge Types Profiled
The article provides quick summaries of popular ammunition types including 9mm Luger (9x19mm), .357 Magnum, .40 SW, .45 ACP, .223 Rem, and .308 Winchester. The author’s favorite pistol round is the 9mm Luger: “9mm is my personal favorite and if there was a “Goldilocks” round, this would be it. The very first gun I bought was a 9mm. They’re fun at the range. They’re good for defense. It is the standard round for NATO countries and the majority of police forces around the world. It is mild shooting, can vary in weight from 115 to 147 grains, and has varying stopping power based on the type of bullet.”

This Pew-Pew Tactical guide to cartridge types also provides a quick explanation of cartridge ignition — both centerfire and rimfire: “The rimfire’s primer is built into the rim while the centerfire cartridge has the primer in the center. Pro tip — if you can see a circle in the middle…it’s a centerfire cartridge.”

There are two common types of centerfire primers — Boxer and Berdan. This helpful Wikipedia illustration shows how Boxer, Berdan, and rimfire primers ignite the powder in the cartridge:

TEN BEST Methods to Dry Cartridge Brass After Wet Cleaning

Wet Tumbling Brass Drier

Many shooters these days clean their cartridge brass ultrasonically, or wet-tumble their cases with stainless media (above). Both methods get brass clean and shiny, inside and out. However, when those wet-cleaning processes are completed, you’re left with a pile of soaking wet brass. How do you dry your brass quickly and efficiently, without unsightly water spots? Read on for some great answers…

In our Shooters’ Forum, Member Terry asked: “How do you dry your brass after Ultrasonic cleaning?” In a Reloading Forum Thread, many smart suggestions were posted. A dozen fellow members outlined a variety of effective case-drying procedures, which work equally well for both wet-tumbled brass and ultrasonically-cleaned cases. Here are the Top 10 brass-drying suggestions from our Forum members.

TOP TEN Ways to Dry Cartridge Brass After Wet Cleaning

1. Food Dehydrator — Shake the brass in towel to get the bulk of water off. Next leave in the food dehydrator for 45 minutes or until there are no signs of moisture inside the cases. — Lawrence97

2. Lyman 5-Level Case Dryer — Rinse off cleaning solution(s), then load brass by type into racks in Lyman Cyclone Case Dryer. This is easier to load/unload than food dehydrators and holds more cases.

Lyman Cyclone Case Drier

3. Hot Water + Compressed Air — Rinse all your cases as a batch using scalding hot water from the kitchen sink. Hot water evaporates off of brass very very quickly. Then hit them with compressed air. Takes 10 minutes. Simple. — SG4247

4. Oven Dry in Pre-Heated Oven — After pre-heating to 200° or so, turn off oven and put brass inside on a tray. Most important! Tell your wife what you are doing so she doesn’t crank it up to 425 to heat pizza! — MClark

NOTE: Many other members suggested oven drying at 150-200°. We recommend turning OFF the oven so you don’t cook your brass if you forget to remove the cases.

Dry Cartridge Brass heat gun5. Towel Dry then Warm with Heat Gun — Roll brass in a towel until no more water shakes out. Lay out on cardboard box top and blow off with Harbor Freight heat gun. $9.99 on coupon. Two minutes of heated air and about half hour of wait and they are good to go. This is with primers removed. — Shaggy357

6. Compressed Air, then Sun Dry Outside – I rinse the brass, then blow them out with compressed air. Then, dependent on the time of year, lay them on a towel in the sun. — HogPatrol

7. Dishwasher on Dry Cycle – In the winter, I drop my wet brass cases neck-down on the rack pegs in the dishwasher, then turn on the dry cycle. In the summer…well, I’m in Texas. They go to the porch for a bit. — Toolbreaker

8. Alcohol Rinse then Air or Oven Dry — Rinse in 90% Isopropyl alcohol and either let air dry or stick in 175° oven for half an hour. Alternatively, use a dehydrator. — Zipollini

9. Slow Air-Dry in Loading Blocks — I have a reloading block with holes drilled in it. I simply load the block up and let it air-dry in the cupboard for a couple of days. — JCS

10. Wipe with Towel Then Anneal Normally — This thread is stirring my OCD side. Seems complicated for just drying — my brass dries just fine when I anneal it. This entire process can’t take an hour per batch. When finished, the brass is cleaned, annealed, and ready to size. — CHLuke

  • Deprime, then tumble brass with stainless media, water, Lemishine, and dish detergent.
  • Shake them easily in a strainer to knock out most media then grab 4-5 pieces, shake them over the bucket for the last of the media then inside a towel.
  • Finally blow out the primer pockets and wipe with a towel, load in the Annealeez.

Barrel Twist Rate and Bullet Stability — What You Need to Know

FirearmsID.com barrel rifling diagram

Understanding Twist: Bullet Stabilization

by Sierra Bullets Ballistic Technician Paul Box for Sierra Bullets Blog.

Based on the questions we get on a daily basis on our 800 (Customer Support) line, twist is one of the most misunderstood subjects in the gun field. So let’s look deeper into this mystery and get a better understanding of what twist really means.

When you see the term 1:14″ (1-14) or 1:9″ twist, just exactly what does this mean? A rifle having a 1:14″ twist means the bullet will rotate one complete revolution every fourteen inches of the barrel. Naturally a 1:9″ turns one time every nine inches that it travels down the barrel. Now, here’s something that some people have trouble with. I’ve had calls from shooters thinking that a 1:14″ twist was faster than a 1:9″ because the number was higher with the 1:14″. The easiest way to remember this is the higher the number, the slower the twist rate is.

Now, the biggest misconception is that if a shooter has a .223 with a 1:8″ twist, his rifle won’t stabilize a 55gr bullet or anything lighter. So let’s look at what is required. The longer a bullet is for its diameter, the faster the twist has to be to stabilize it. In the case of the .223 with a 1:8″ twist, this was designed to stabilize 80gr bullets in this diameter. In truth the opposite is true. A 1:8″ will spin a 55gr faster than what is required in order to stabilize that length of bullet. If you have a bullet with good concentricity in its jacket, over-spinning it will not [normally] hurt its accuracy potential. [Editor’s Note: In addition, the faster twist rate will not, normally, decrease velocity significantly. That’s been confirmed by testing done by Bryan Litz’s Applied Ballistics Labs. There may be some minor speed loss.]

FirearmsID.com barrel rifling diagram
Many barrel-makers mark the twist rate and bore dimensions on their barrel blanks.

Think of it like tires on your truck. If you have a new set of tires put on your truck, and they balance them proper at the tire shop, you can drive down a street in town at 35 MPH and they spin perfect. You can get out on the highway and drive 65 MPH and they still spin perfect. A bullet acts the same way.

Once I loaded some 35gr HP bullets in a 22-250 Ackley with a 1:8″ twist. After putting three shots down range, the average velocity was 4584 FPS with an RPM level of 412,560. The group measured .750″ at 100 yards. This is a clear example that it is hard to over-stabilize a good bullet.

Great .22 LR Rimfire Ammo Comparison Test — 31 Types Tested

Shooting Sports USA .22 LR 22LR Rimfire ammunition test subsonic hi-velocity lead-free hyper velocity suppressor match ammo plinking varmint hunting

Here’s a “must-read” article for .22 LR rimfire shooters. The October 2018 issue of Shooting Sports USA (SSUSA) includes a great article with data on thirty-one (31) different types of popular .22 LR rimfire ammunition. The line-up includes low-speed, standard, and Hi-Velocity types, plus choices for plinking, varminting, and target applications. Brands tested include: Aguila, American Eagle, CCI, Federal, Fiocchi, Lapua, Remington, and Winchester. The slowest ammo, CCI Quiet-22 Lead RN, clocked 727 FPS. The fastest ammo, CCI Short-Range Green Lead-Free HP, ran 1735 FPS, 2.4 times the speed of the Quiet-22.

SSUSA .22 LR Rimfire Ammo TEST | SSUSA October 2018 Issue

For each ammo type, SSUSA lists the bullet weight, velocity (FPS), and average of two, 5-shot groups at fifty yards. The most accurate ammo was Lapua Center-X LRN, with a 0.37″ average 50-yard group size. Second best was Lapua X-ACT LRN at 0.42″. Ammo was tested from a bench with a Cooper Model 57-M rifle fitted with 3-9x33mm Leupold VX-2 scope. The ammo offerings were grouped into three categories: (1) Varmints/Small Game; (2) Target; and (3) Plinking. (See ammo tables below.)

Different types of .22 LR (Long Rifle) rimfire ammo have different applications. Subsonic ammo, typically, is best for 25m to 50m target work with precision rimfire rigs. Hi-Velocity .22 LR ammo provides a flatter trajectory for longer ranges. SSUSA explains: “The array of .22 LR loads… turns a person’s head every which way. Subsonic target loads are the key to decisive accuracy on targets, while hyper-velocity cartridges provide striking bullet expansion on small varmints. In between, standard and high-velocity .22 LRs are loaded with a variety of bullet weights and styles for everything from small-game hunting to plinking[.]” READ Full SSUSA .22 LR Rimfire Ammo Story.

Could You Shoot 0.8 MOA at 300m — for FIVE HUNDRED Shots?

Sierra Bullets 500 round tunnel test

For load development, some guys shoot 3-shot groups. Other guys shoot 5-shot groups, or even 10-shot strings. But for testing its projectiles, Sierra Bullets takes it to another level entirely. A while back Sierra was testing its .30-Caliber 175gr HPBT MatchKing in the Sierra underground tunnel. The results appear above — a FIVE HUNDRED Round group!

500 Shots Form 0.82 MOA Group at 300m (328 yards)
Sierra’s trigger-pullers sent five full boxes of bullets down-range at a single target. The photo above shows the result of 500 shots taken in a 300 meter test tunnel. The raw group size, edge to edge of the farthest shots, is about 3.13 inches, as shown on the calipers’ metal linear scale. Subtract a .308″ nominal bullet diameter* to get the 2.823″ on the digital readout. So you’re seeing a 2.823″ group at 300 meters (328 yards). One MOA at this distance is 3.435″ so this 500-round group is 2.823 divided by 3.435 or 0.82 MOA (0.8218 MOA to be precise).

This 500-round group was shoot as part of a pressure/velocity test for a commercial customer. The cartridge was .308 Winchester, loaded at 2.800″. The powder was Reloder 15. A 26″ barrel was shot from a return to battery rest. The gun was cleaned every 125 rounds and two foulers shot.

What do you think — could you beat this group from a bench for 500 rounds?

One Facebook poster joked: “500-round group? Everyone knows anything less than 1000-round groups are a waste of time and statistically irrelevant.”

Test Tunnel Sierra

Sierra Bullets Test Tunnel Barrels

Sierra’s 300 Meter Testing Tunnel
Ever wonder how (and where) Sierra tests its bullets? The answer is underground, in a 300-meter test tunnel located under Sierra’s factory in Sedalia, Missouri. The photo above shows the construction of the tunnel back in May, 1990. Like most bullet manufacturers, Sierra does live-fire bullet testing of its projectiles. Sierra’s 300-meter test range is the longest, manufacturer-owned underground bullet test facility in the world. In years past, Sierra offered free visits to the test tunnel as part of a factory tour.

* Normally, to get an exact group size, you should subtract the TRUE bullet hole size, which is usually smaller than the nominal bullet diameter. E.g. a .308 bullet hole may show on paper as .298 or so. But here, for simplicity, we are subtracting .308″ because we do not have the original target to measure.

Reloading Powder Storage — Important Guidelines to Follow

Western Powders Blog SAAMI Storage

SUMMARY: Powder can have a very long shelf life. You need to watch for changes in smell and color. A reddish tinge, almost like rust on the powder, is a bad sign, as is a foul odor, not to be confused with a normal chemical smell. Either of these signs indicate it is time to dispose of your powder by means other than shooting.

Ever wondered about the stability of the propellants in your reloading room? There are some important things you should know about powder storage, to ensure consistent powder performance and safety. Western Powders (which has been acquired by Hodgdon) published an informative Q & A series entitled Dear Labby: Questions for our Ballistics Lab . Here are some excerpts that pertain to powder storage and shelf life. Worried that your powder may be too old? Western’s experts explain how to check your propellants for warning signs.

Proper Powder Storage

Q: I live in southern Arizona where it is very hot. I am told powders will become unstable if stored in an area not air-conditioned. My wife says no powder or primers in the house. Can powder be stored in a refrigerator? What about using a fireproof safe? I would appreciate your ideas. — M.C.

Lab Answer: SAAMI guidelines are pretty clear on issues of storage. They recommend storing smokeless powder in containers that will not allow pressure to build if the powder is ignited — ruling out gun safes and refrigerators.

CLICK HERE to Read SAAMI Guidelines for Powder Storage (PDF)

In their original containers, the lifespan of smokeless powders is quite long, even in hot, arid climates. In fact the lifespan is typically longer than the average handloader would need to store them. Stored safely in a garage or outbuilding, your powder should last years. If you see the powder developing a reddish tint, or giving off a foul odor, it is time to discard it.

Clumps in Powder Container

Q: I ordered some of your Accurate 1680 powder back about in December. I just now opened it … and it is full of clumps. My knowledge tells me that means moisture. Am I wrong? I just now broke the seal and it has been stored in a ammo can with desiccant packs around it and a dehumidifier running 14-16 hours a day. I can’t imagine this being my fault, if this does indicate moisture. I don’t know if the pink part on the label is suppose to be red or not, but it is definitely pink, so if it was red I am wondering if I was shipped an old container? I hope that this isn’t bad and I am stuck with it…

Lab Answer: All powder contains a certain amount of moisture. When the powder is stored or during shipping, it can go through temperature cycles. During the cycling, the moisture can be pulled to the surface and cause clumping. Clumping can also be caused by static electricity if too dry or the powder has limited graphite content. You can break up the clumps before metering and they shouldn’t be a problem. This will not affect the powder performance, so your product is fine. Accurate 1680 labels are designed in Pink. As a side note, specification for testing powder is at 70° F and 60% humidity.

Shelf Life and Packaging Dates

Q: Does powder ever get to old to use and what identifying marks does your company put on the canister for when it is made, You have helped me out a while ago when I asked about keeping my cowboy shooting under 950 fps and it works great less stress on the hand and the recoil is very minimum. — R.B.

Lab Answer: On one pound bottles, the number is on the corner in a silver box. If the powder was poured today, it would read 012815 followed by a lot number. The whole number would look something like 012815749. Eight pound bottles have a sticker on the bottom with an obvious date code. The lot number appears above the date.

TECH Tip — 30 BR Case-Forming Explained by Experts

30BR 30 BR case forming benchrest randy robinette al nyhus

30BR 30 BR case formingThe 30BR is an amazing little cartridge. However, 30BR shooters do have to neck-up 6mmBR brass and then deal with some issues that can arise from the expansion process. One of our Forum members was concerned about the donut that can form at the new (expanded) neck-shoulder junction. Respected bullet-maker Randy Robinett offers tips on how to deal with the “dreaded donut”.

The Forum member was concerned about thinning the brass if he turned his 30BR necks after expansion: “Everything I have found on 30BR case-forming says to simply turn off the bulge at the base of the neck caused by the old 6BR shoulder. I expanded my first case and measured the neck at 0.329″ except on the donut, where it measures 0.335″. Looking inside the case… reveals a groove inside the case under the donut. Now, it is a fact that when I turn that neck and remove the donut, the groove is still going to be there on the inside? That means there is now a thin-spot ring at the base of the neck that is .005 thinner than the rest of the neck. Has anyone experienced a neck cracking on this ring?”

Randy Robinett, who runs BIB Bullet Co., is one of the “founding fathers” of the 30BR who help prove and popularize the 30 BR for benchrest score shooting. Randy offers this advice on 30BR case-forming:

While the thinner neck-base was one of our original concerns, unless one cuts too deeply INTO the shoulder, it is not a problem. For my original 30BR chamber, thirty (30) cases were used to fire 6,400 rounds through the barrel. The cases were never annealed, yet there were ZERO case failures, neck separations, or splits. The case-necks were turned for a loaded-round neck diameter of .328″, and, from the beginning, sized with a .324″ neck-bushing.

The best method for avoiding the ‘bulge’ is to fire-form prior to neck-turning (several methods are successfully employed). Cutting too deeply into the shoulder can result in case-neck separations. I have witnessed this, but, with several barrels and thousands to shots fired, have not [personally] experienced it. The last registered BR event fired using that original barrel produced a 500-27x score and a second-place finish. [That’s] not bad for 6K plus shots, at something over 200 firings per case.

Check out the 30BR Cartridge Guide on AccurateShooter.com
You’ll find more information on 30BR Case-forming in our 30 BR Cartridge Guide. Here’s a short excerpt from that page — some tips provided by benchrest for score and HBR shooter Al Nyhus:

30BR Case-Forming Procedure by Al Nyhus
The 30BR cartridge is formed by necking-up 6BR or 7BR brass. You can do this in multiple stages or in one pass. You can use either an expander mandrel (like Joe Entrekin does), or a tapered button in a regular dies. Personally, I use a Redding tapered expander button, part number 16307. This expands the necks from 6mm to .30 cal in one pass. It works well as long as you lube the mandrel and the inside of the necks. I’ve also used the Sinclair expander body with a succession of larger mandrels, but this is a lot more work and the necks stay straighter with the Redding tapered button. This button can be used in any Redding die that has a large enough inside diameter to accept the BR case without any case-to-die contact.

Don’t be concerned about how straight the necks are before firing them the first time. When you whap them with around 50,000 psi, they will straighten out just fine! I recommend not seating the bullets into the lands for the first firing, provided there is an adequate light crush-fit of the case in the chamber. The Lapua cases will shorten from approx. 1.550″ to around 1.520″ after being necked up to 30-caliber I trim to 1.500″ with the (suggested) 1.520 length chambers. I don’t deburr the flash holes or uniform the primer pockets until after the first firing. I use a Ron Hoehn flash hole deburring tool that indexes on the primer pocket, not through the case mouth. — Al Nyhus

Cartridge Headspace 101 — Understanding the Basics

Brownells Headspace Gauge cutaway chamber drawing SAAMI ANSI

Do you know what the inside of a rifle chamber (and throat zone) really looks like? Do you understand the concept of headspace and why it’s important? If not, you should read the Brownells GunTech article Gauging Success – Minimum Headspace and Maximum COL. This article explains the basics of headspace and shows how to measure headspace (and length to lands) in your barrels with precision. The article also explains how to adjust your full-length sizing dies to “bump the shoulder” as needed.

Why is headspace important? The article explains: “Controlling headspace and setting proper C.O.L. also represent improved safety and reduced cost of handloading. Excessive headspace can cause case head separation and gases in excess of 60,000 PSI escaping from a rifle’s chamber. Too little headspace can result in a chamber forced bullet crimp and a bullet that becomes an obstruction more than a properly secured projectile. Excessive C.O.L. can result in a rifling-bound bullet, a condition that could result in spikes of excessive pressure.” [Editor’s NOTE: It is common for competitive benchrest shooters to seat bullets into the rifling. This can be done safely if you reduce your loads accordingly. With some bullets we often see best accuracy .010″ (or more) into the lands. However, this can generate more pressure than the same bullet seated .010″ away from initial lands contact. As with all reloading, start low and work up gradually.]

Brownells Headspace Gauge cutaway chamber drawing SAAMI ANSI

How is headspace specified? Most cartridges used within the United States are defined within ANSI/SAAMI Z299.3-4. Brownells explains: “In the case of the .243 Winchester, as an example, there are pressure specifications, cartridge drawings and, as pictured above, chamber drawings. Armed with a chamber drawing, each manufacturer producing a firearm for the .243 Winchester knows the proper standard dimension to cut chambers and set headspace. Notice there are two headspace reference dimensions for the chamber. The upper is a place in the chamber where the shoulder is .400″ in diameter; the “datum” or “basic” line. The lower is the 1.630″~1.640″ minimum – maximum dimension from the breech face (bolt face) to that point in the chamber that measures .400″.”

The actual headspace of any firearm is the distance from the breech face to the point in the chamber that is intended to prevent forward motion of a cartridge.

Finding Cartridge Length to Lands with OAL Gauge
Using a comparator on a set of calipers, you can quickly determine cartridge base-to-ogive length. This is the measurement from the base of the case to the forward-most full diameter section of the bullet, typically called the ogive. Shown here, that ogive is 0.243″ diameter.

The next step is using a modified (threaded) case with a Hornady OAL tool to determine Length-to-Lands (LTL) in your rifle’s chamber. During this measurement process, the modified case, with a bullet in its neck, is inserted in the chamber. Go slow, take your time. Here are 5 tips that will help you get repeatable and reliable LTL measurements:

1. Start with a clean chamber and clean barrel throat.
2. Make sure the modified case is fully screwed down and seated on the OAL Gauge. It can sometimes unscrew a bit during repeated measurements.
3. Insert the modified case slowly and gently, but ensure the shoulder of the modified case is fully seated on the end of the chamber.
4. Push the gray plastic rod GENTLY. It is common for the bullet to be tilted a bit. You want to allow the bullet to self-center in the throat BEFORE you apply much pressure. Then tap a couple times and push until you feel resistance. Do NOT push too hard — that will jam the bullet in the lands.
5. Repeat the measurement at least 3 more times. If you follow our instructions, you should, typically, get a repeatable measurement, within 0.0015″ or so, 3 out of 4 times.
