Sierra Bullets has released very complete 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.
Developed 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.

Many of our readers are thinking of trying out PRS-type competition. Tactical matches are becoming more popular every season. Along with F-Class, tactical/practical disciplines are the fastest-growing forms of competitive rifle shooting. Rich Emmons, one of the founders of the Precision Rifle Series (PRS), has written an insightful article about getting started in the tactical game. This will help PRS novices pick the right equipment and understand the game. Here are highlights from Emmon’s “PRS — Intro to Competition” article, originally published on the PRS website. You may also want to read the current PRS FAQ Page.
Precision Rifle Series — Intro to Competition
by Rich Emmons, PRS President
Tactical Shooting with a precision rifle is not like other disciplines, there is no set course of fire or format. That is what makes it so fun!
First, you have to ask yourself what do you want to accomplish. When I was introduced to long range shooting, immediately a light turned on for me, once I saw how easy it was to hit 300–600 yard targets. What I quickly learned from my first competition and the many that followed was there is so much to learn and shooting in competition put everything you thought you knew to the test. So back to the question: “What do YOU want to accomplish?”. The reality is you may not know yet, you just think it is cool to have a bad ass rifle and scope that can make almost any shot. Now if you’ve got that rifle and scope, it’s time to take it to the next level.

Getting Started — What to Expect
If you’re reading this, you have probably already have been bitten by the long range shooting bug. It can seem quite intimidating to just jump in with a new bunch of shooters you don’t know and shooting lingo you don’t quite understand yet. But here is the key — show up and shoot! I guarantee you if you show up to a match as a new shooter, other experienced shooters will guide you along and give you help on anything you need.
AUDIO: Click Button to hear Rich Emmons Talk about the Precision Rifle Series.
Now, a couple things you should just expect. You’re not as good as you think you are. Don’t expect to come into your first match and beat all the veterans. That just doesn’t happen unless you have had some really good coaching or other shooting competition experience to get you ready for this type of competition. If possible, find a local rifle club that has monthly long range matches, or any type of match will help prepare you for a larger PRS event. Getting involved with a rifle club and starting out shooting monthly matches is definitely the way to jump into competition shooting.
The Gear You Need
The first question that many ask is: “What kind of rifle/caliber/scope do I need?” The easiest answer to this is, the best you can afford. It’s no secret the gear is expensive. It took me several years of buying sub-par gear and eventually trading up to figure this out. Now, a guy can get a real sense of pride of doing it on the cheap, or with a factory rifle. I’ve seen many old Savage 10FPs take down custom rigs that cost 10 times as much. And if that’s all you can afford, then eventually you will learn the limitations of yourself or your gear. As for choice of cartridge/caliber, the respected Precision Rifle Blog has analyzed five years worth of match results from the best tactical shooters in the nation. CLICK HERE to read a PRB article that reveals what cartridge types the “top guns” use.
Craig Arnzen of Area 419 has created a useful article reviewing the gear PRS shooters need, including support bags, hearing protection, and other key accessories such as muzzle brakes. This helpful article also covers factory ammunition options.
Making Good Ammo
Producing quality reloads is something you have to master. It’s not hard at all, you just have to pay attention to detail, and eventually you are going to do something stupid like mis-priming your brass, or skip a row of brass when dumping your powder. Everybody has their own horror story of some reloading failure that cost them a stage or even a match. So load to perfection, work with your rifle to find what load it likes the best, then start your practice.
Practice Makes Perfect
You want to become ONE with your rifle, learning everything you can about its functionality. Getting comfortable with the operation of your rifle is key. Learn the feel of your trigger, dry-firing until you wear the paint off your bolt handle. Learn how the rifle works best — pay attention to little things like the sound and feel of the bolt feeding a round from the mag (or when it doesn’t). Learn how to remove a jammed round quickly, learn how to reload a magazine quickly. Learn to scan across a field and find targets in a quick manner, seeing the targets with your eye and coming into the scope on target. These are some of the basic practices that separate the new shooters from the seasoned ones.

Summer Solstice 2020 was June 20th, and July’s nearly here. That means “peak heat” summer conditions. It’s vitally important to keep your ammo at “normal” temps during the hot summer months. Even if you use “temp-insensitive” powders, studies suggest that pressures can still rise dramatically when the entire cartridge gets hot, possibly because of primer heating. It’s smart to keep your loaded ammo in an insulated storage unit, possibly with a Blue Ice Cool Pak if you expect it to get quite hot. Don’t leave your ammo in the car or truck — temps can exceed 140° in a vehicle parked in the sun.
To learn more about how ambient temperature (and primer choice) affect pressures (and hence velocities) you should read the article Pressure Factors: How Temperature, Powder, and Primer Affect Pressure by Denton Bramwell. In that article, the author uses a pressure trace instrument to analyze how temperature affects ammo performance. Bramwell’s tests yielded some fascinating results.
For example, barrel temperature was a key factor: “Both barrel temperature and powder temperature are important variables, and they are not the same variable. If you fail to take barrel temperature into account while doing pressure testing, your test results will be very significantly affected. The effect of barrel temperature is around 204 PSI per F° for the Varget load. If you’re not controlling barrel temperature, you about as well might not bother controlling powder temperature, either. In the cases investigated, barrel temperature is a much stronger variable than powder temperature.”
This Editor had the personal experience of 6mmBR hand-loaded ammo that was allowed to sit in the hot sun for 45 minutes while steel targets were reset. The brass became quite warm to the touch, meaning the casings were well over 120° on the outside. When I then shot this ammo, the bullets impacted well high at 600 yards (compared to earlier in the day). Using a Magnetospeed, I then chron-tested the sun-heated ammo. The hot ammo’s velocity FPS had increased very significantly — all because I had left the ammo out in the hot sun uncovered for 3/4 of an hour.
Powder Heat Sensitivity Comparison Test
Our friend Cal Zant of the Precision Rifle Blog recently published a fascinating comparison test of four powders: Hodgdon H4350, Hodgdon Varget, IMR 4451, and IMR 4166. The first two are Hodgdon Extreme powders, while the latter two are part of IMR’s Enduron line of propellants.
The testers measured the velocity of the powders over a wide temperature range, from 25° F to 140° F. Hodgdon H4350 proved to be the most temp stable of the four powders tested.

Are you looking for a muzzle brake for your rifle? Then you MUST check out the epic Muzzle Brake Test performed a few seasons back by PrecisionRifleBlog.com. This massive, data-driven field test was organized by PRB head honcho Cal Zant. Over a period of months, Cal and his team tested 20+ muzzle brakes designed for 6mm, 6.5mm, and .30-caliber precision rifles. Hundreds of hours went into this research, which provided vital new insight and empirical data for several aspects of muzzle devices. Cal put a huge amount of labor/engineering into these tests and his findings deserve to be widely read.
The Muzzle Brake Overview Article covers designs, specs, and prices of 20+ brakes. Then separate, detailed PRB articles cover sound levels, recoil reduction results, ability to stay on target, muzzle blast/ground effects and more. SEE PRB Muzzle Brake Test Results SUMMARY.
Recoil Reduction
Cal created a system to directly measure the entire recoil force signature of each muzzle brake using high-speed sensors. Although the recoil cycle happens very quickly (around 1/100th of a second), his test equipment could record up to 1,000 force data points during a single recoil cycle! He fired over 1,000 rounds of match-grade ammo through four different rifles: 6XC, 6.5 Creedmoor, .308 Win, and the monster .300 Norma Magnum. He literally spent thousands of dollars on this part of the test, to ensure he got it right.
Cartridge Types Tested: 6XC, 6.5 Creedmoor, .308 Win, and .300 Norma Magnum
Ability To Stay On Target
David Tubb helped Cal develop this part of the test, because David believes this is the most important aspect of a muzzle brake. Using a laser and high-speed camera, Cal was able to objectively quantify how well each design helped you stay on target.
Noise Level
Muzzle brakes are loud, but some are louder than others … three to four times as loud. Cal enlisted the help of an expert from the suppressor industry to precisely measure how much louder each muzzle brake made a rifle. Each brake was tested in accordance with MIL-STD-1474D using calibrated military-approved equipment, and the noise level was also tested at the shooter’s position.
Recoil Reduction Summaries by Caliber
In the detailed summaries of recoil reduction test results, PRB provides hard data that might surprise a few people and even dispel a few myths. Particularly interesting is Zant’s comparison of recoil reduction with a suppressor compared to muzzle brakes. How do you think the suppressor performed compared to the brakes? You may be surprised.
Well folks, it’s July 6th already — the means we’re moving into “peak heat” summer conditions. It’s vitally important to keep your ammo at “normal” temps during the hot summer months.

The MasterPiece Arms BA Chassis is a leading product choice according to a recent Precision Rifle Blog (PRB) survey of Precision Rifle Series (PRS) and National Rifle League (NRL) competitors. Second were Manners Stocks, and third were Foundation-brand systems. PRB Editor Cal Zant surveyed 150 PRS and NRL precision rifle shooters to determine what gear they run in long range rifle competitions. The MPA BA Competition Chassis ranked #1 with 27% of the PRS and NRL shooters surveyed running this particular modular chassis system. READ Full PRB Stocks and Chassis Survey.
MPA BA Competition Chassis
MPA has several configurations of its highly successful BA Chassis System, with the MPA BA Competition Chassis named the Official Chassis of the 2019 PRS. This competition version includes all the standard features of the original, but includes special enhancements for long range tactical rifle competitions, such as the PRS and related events. There are additional hole locations on the fore-end for locating the rotating barricade stop, which locks the rifle in place when shooting on a variety of barricade designed stages. The spigot mount attaches to the front of the fore-end, giving the shooter additional space to mount their bipod. A bag rider attachment provides better rear bag recoil management (an Enhanced Bag Rider is available for an additional fee).
MPA president Phil Cashin is an active PRS shooter who finished in the top 100 in 2017 and qualified for the finale last year. Cashin, shown in the video below, regularly tests out new ideas and upgrades in actual competition and seeks out feedback from top tactical competitors. “It’s a great honor [for MPA] to be named the most popular brand of chassis/stock systems amongst the top PRS and NRL competitors[.] We look forward to developing even more products with the long-range precision shooter in mind,” said Cashin.
MPA Production Class Rifle
MPA also offers a PRS Production Class Rifle (PCR) using the MPA Chassis system mated to a Savage Model 12 action. Production Class rifles may cost no more than $2000.00 before optics. Designed specifically for the new PRS Production Class, MPA’s PCR Competition Rifle offers many premium features yet stays under the $2,000 Class limit. The Savage action is upgraded with a Rifle Basix 2-lb trigger, and the adjustable, modular chassis offers a bag rider, barricade stop, and built-in bubble level.

A while back, Cal Zant at PrecisionRifleBlog.com did a big muzzle brake comparison test. Along with measuring recoil reduction, Cal’s team recorded sound levels in PRB’s exhaustive muzzle brake field test. In the PRB archives you’ll find comprehensive muzzle brake sound test results, with hard data on 20 different muzzle brakes.
Sound can be a tricky subject, but Cal Zant, the editor of PrecisionRifleBlog.com, presents everything an informed shooter should know about muzzle brake noise in a straightforward and practical way. Most sound tests are measured from the side of the muzzle, in accordance with mil-spec standards, and Cal did that. But he also measured the sound level of each brake from behind the rifle, closer to the shooter’s position. This provides a more accurate indicator of the actual sound levels firearms operators will encounter while shooting.
Muzzle brakes ARE really loud — that’s something most active shooters have observed. But this study finally gives us some hard data and makes objective comparisons. The difference between brakes was quite significant. Some brakes were ear-splitting — more than twice as loud as other brakes tested.
As a bonus, Cal also provides data on how the new Ultra series suppressors from Thunder Beast Arms Corp (TBAC) compare in terms of sound level behind the rifle.
A couple seasons back, PrecisionRifleBlog.com (PRB) published a significant field test of powder temperature stability. The test was designed to quantify the temperature stability of Hodgdon H4350 and Varget powders compared to IMR’s Enduron line of powders, specifically IMR 4166 and 4451. The results were very interesting, to say the least…
Hodgdon Extreme Series powders have attracted quite a fan base, with over 90% of the top shooters in the Precision Rifle Series choosing to run one of those powders. IMR offers a modern line of powders “with Enduron Technology” — which is also marketed to have “extreme temperature stability”. Sounds familiar! These new powders should compete directly with the Hodgdon Extreme Series, which gives shooters more temp-stable powder options to consider.
The top shooters in the PRS and veteran long-range shooters in other disciplines have learned to value a temperature-stable powder. That’s because a change in temperature can affect the trajectory or “flight path” of the bullet in two well-known ways:
1. Assuming all other environmental conditions remain the same, an increase in air temperature will cause a flatter trajectory due to a lower air density (easier for the bullet to cut through the air).
2. The same increase in temperature also causes the nitrocellulose-based powder inside the cartridge to burn at a higher rate, producing approximately four times the Point of Impact (POI) shift than just air temperature alone. (SEE: Temperature Effects On Zero on KestrelMeters.com.)
“The initial heat condition of your powder will affect the burn rate,” Bryan Litz explained at a recent Applied Ballistics Seminar. That means swings in ambient outside temperature can affect your internal ballistics, which will directly affect your muzzle velocity, which will change your bullet’s trajectory. Some powders are more affected by changes in temperature than others. So if your goal is first-shot hits and you may shoot in a variety of conditions — you should care about temperature stable powders.
The folks at PrecisionRifleBlog.com meticulously loaded 6.5×47 Lapua ammo with each powder using some of the best equipment available. This included the top-of-the-line Prometheus Gen II Powder Scale, which is capable of loading to the nearest kernel of powder. This ensured the powder charges were identical for each round of ammo. PRB’s testers explain the full set of equipment and steps in their loading process in the Full Test Report.
Once they had a couple dozen rounds loaded with each powder, they went and shot them with each powder at 25° F, 65° F, and 140° F. The muzzle velocity of each shot was recorded using BOTH a LabRadar Doppler Radar and a MagnetoSpeed Chronograph. That provided two sets of velocity numbers. When placed and configured optimally, the LabRadar can measure muzzle velocity with +/- 0.1% accuracy, according to the manufacturer.
Here are the results from the PRB Powder Temp Stability Tests:
You can see Hodgdon H4350 had the least variance in muzzle velocity, with just 25 fps over the 115° swing in temperature! That is very, very low. Hodgdon Varget was the second least temperature sensitive powder in this test, with 46 fps of variance in muzzle velocity between temperatures of 25° F and 140° F. IMR 4166 performed very similar to Varget, and proved to be fairly insensitive to large swings in temperature. IMR 4451 had the largest swing in muzzle velocity of the powders tested, but keep in mind just 68 fps over 115° F swing is still a good performance.
Most powders aren’t specially formulated to be temperature stable. So they would likely show much larger swings than what these four top-performing powders showed. However, Alliant’s relatively new Reloder 16 is an extremely temp-stable powder, with a burn rate that is a close match to H4350. Many F-Open competitors are now using Reloder 16 with considerable success.
PRB’s test team also noticed other interesting trends in the data. For example, variation in velocity does NOT appear to be linear across the full range of temperatures. By that, they mean the change per degree from 20° to 65° might be smaller or larger than the change per degree from 65° to 140°.
Well folks, it’s July 1st already — the means we’re moving into “peak heat” summer conditions. It’s vitally important to keep your ammo at “normal” temps during the hot summer months. Even if you use “temp-insensitive” powders, studies suggest that pressures can still rise dramatically when the entire cartridge gets hot, possibly because of primer heating. It’s smart to keep your loaded ammo in an insulated storage unit, possibly with a Blue Ice Cool Pak if you expect it to get quite hot. Don’t leave your ammo in the car or truck — temps can exceed 140° in a vehicle parked in the sun.

PrecisionRifleBlog.com recently reviewed several video-based rifle training DVD sets. While instructional DVDs will never replace live “hands-on” training, they can be cost-effective ways to sharpen your skills. Watched periodically, these training DVDs can help reinforce the fundamentals.
PRB’s Editor Cal Zant has purchased several rifle training DVDs over the years. His recent Precision Rifle Blog DVD review looks at four different options:
Long Range Made Easy, Two-Volume Set, from Accuracy 1st The Art Of The Precision Rifle, with Todd Hodnett (Magpul Dynamics) Putting Rounds On Target, with Bryan Litz (Applied Ballistics) Rifles Only — Precision Rifle Instructional DVDs, with Jacob Bynum
Cal reports that each of these four titles offers a slightly different approach, with each instructor displaying his own focus, based on his background and expertise.
Accuracy 1st’s Long Range Made Easy Two-Volume Set seemed to win PRB’s Editor’s Choice Award. The tagline on the DVD is: “Go from basic to advanced with the guy that has trained our best military snipers for the past 10 years.” That’s a pretty good description. Todd Hodnett is the primary instructor, and Bryan Litz joins him in several segments.
It’s the best of both worlds. Todd Hodnett’s pragmatic “the-bullet-cannot-lie” approach (field-proven by hundreds of the world’s best snipers), is combined with Bryan Litz’s engineering approach and vast knowledge of external ballistics verified with carefully recorded live-fire experiments. The two styles complement each other well, and provide an extremely well-rounded and comprehensive overview.
The DVD set is split into two volumes, each of which includes two discs. All together there are almost four hours of instruction from the most respected guys in the industry. And they cover a lot of ground — you’d never be able to cover this much in a one- or two-day live class. Plus with the DVD you can easily repeat an important point, and watch the whole program more than once.
Cal paid $76.95 out-of-pocket for the Long Range Made Easy, Vol. 1 & 2 Bundle, so his review wasn’t a paid advertisement. He thought this set provides a ton of value, and could help a lot of shooters. Here are key topics covered in Long Range Made Easy:
■ Advice for Gear Purchases
■ Optimal Gun Setup
■ Technique for Position
■ Simple & Quick Wind Formula
■ Using the Applied Ballistics Kestrel
■ Truing Ballistic Algorithms, Drag Scale Factoring, and Custom Drag Models
■ WEZ Analysis
■ Wind Course

For a prone shooter, particularly on dusty, dirty or sandy ground, muzzle blast is a major bummer. Muzzle blast can be very disturbing — not just for the trigger-puller but for persons on either side of the gun as well. Some muzzle brakes send a huge shockwave back towards the shooter, and others send blast towards the ground, kicking dirt and debris into the prone shooter’s face. If there was a way to illustrate those factors — shockwave and debris — that might help shooters select one brake design over another.
Cal Zant at PrecisionRifleBlog.com applied a unique blend of creativity and resourcefulness to try to answer that question for 20+ muzzle brakes. Using high-speed photography and household products, he captured the blast pattern of 20+ different brake designs for easy side-by-side comparison. Can you figure out how Cal managed to show muzzle brake blasts so clearly? His “hi-viz” solution, revealed in the article, is very clever.

Developed 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.
