Sunday GunDay: New 6GT Cartridge Tested in 3 Tactical Rifles

6GT Cartridge Alpha Munitions GA Precision PRS NRL brass 6.5x47 Lapua fire-formed neck-turn project

The New 6GT Cartridge for Precision Rifle Competition

Report by Vu Pham
Earlier this year I was ready to build a 6 Dasher when I saw a lot of buzz on the interwebs about a new caliber George Gardner (Owner of GA Precision) and Tom Jacobs (Owner of Vapor Trail Bullets) designed, the 6GT. After some research and talking to George, I ditched the 6mm Dasher build and had GA Precision build me a 6GT on a GAP Templar action I already had in the safe. The reasons to try the 6GT in a new PRS-style rig were as follows:

1. Push a 110-115 grain class bullet at 2880-2930 FPS safely in the Sacramento heat.

2. Achieve a load that is reliable and predictable. The caliber must be easy-to-tune and predictable from barrel to barrel. I don’t want to spend weeks developing a new load each time I spin on a fresh barrel.

3. Be able to run the same mag in all my guns without having to tweak or use mag kits. The round must feed from AICS and AW magazines without major tweaking or hiccups.

4. Get good barrel life. The barrel needs to go 2200-2500 rounds with match-grade reliability and accuracy.

5. Have a competitive cartridge with the least possible recoil without sacrificing too much performance down range, compared to bigger options like the 6mm Creedmoor.

6GT feeding from un-modified magazines has been flawless in all the rifles we tested. The 6GT feeds so well, I sometimes have to do a press check to ensure there is a round in the chamber.

On paper the 6GT seemed like the perfect cartridge for PRS- and NRL-style competition. It has the low recoil of a 6 Dasher, with good feeding and mag compatibility. With the 6GT, a competitor can push 105gr bullets at 3000+ FPS or run heavier bullets at 2800-2900+ FPS.

6GT Cartridge PRS NRL brass 6.5x47 Lapua 6GT 6mm Dasher cartridge fire-formed neck-turn project

Knowing that I would initially have to make my own 6GT brass and do quite a bit of load development, I enlisted the help of Dan Bertocchini with CS Tactical. Dan has a lot more experience with wildcats and is the man when it comes to this type of data gathering. He has been running a 6 Dasher for a few years so I was curious how he would compare the 6GT to his 6 Dasher.

Quick Summary: “I am really digging the 6GT and the capabilities it offers. It can launch 103gr Vapor Trails at 3000+ FPS or lob heavy 115gr DTACs in the low-to-mid 2900s comfortably. I think we will see this cartridge go mainstream in PRS/NRL-style competition in 2020.” — Vu Pham

6GT Cartridge Alpha Munitions GA Precision LabRadar PRS NRL brass 6.5x47 Lapua fire-formed neck-turn project

Alpha Munitions Pre-Production 6GT Brass
6gt brass cartridge Alpha Munitions PRS 6mm DasherGeorge Gardner was kind enough to send us 50 pieces of Pre-Production Alpha 6GT brass for preliminary testing. Like the cases I formed from 6.5×47 Lapua brass, the Alpha 6GT brass will use a small rifle primer. Price from Alpha Munitions should be $1.15 per case, which is on par with Alphan’s other product line.

The first 7000 pieces of Alpha 6GT brass sold before I could even get my hands on any! The bigger batch of production brass is due later this year. To pre-order the brass, CLICK HERE.

The major difference between 6.5×47 Lapua-formed brass and Alpha 6GT brass is the case capacity. Alpha 6GT brass has 1.5 to 1.7 grains more case capacity. When a piece of 6.5×47 Lapua brass is formed into a 6GT, the walls of the case now become the shoulder and part of the neck. In a normal piece of brass, the shoulder and neck are typically thinner because of the thickness of the brass tapering from the body to neck.

While the cartridge design was optimized for Hodgdon Varget, the extra case capacity of the Alpha 6GT brass opens the door to Hodgdon H4350 (my favorite powder) and Alliant Reloder 16.

Test Results with Alpha Munitions 6GT Brass
Initial test results were as expected from a premium brass-maker. Dan and I both got excellent Standard Deviations and Extreme Spreads over my MagnetoSpeed V3 and his LabRadar. This string below was with 112gr Barnes Match Burners and 33.8 grains of Varget. Can’t complain about a 3 FPS Extreme Spread!

Yes, H4350 Works with the Alpha Munitions Brass
Personally, I prefer running Alpha 6GT brass with H4350 rather than Varget pushing a heavier bullet. H4350 burns slower and cleaner which should equate to better barrel life. The Lapua-formed 6GT cases just do not have the capacity to reach the cartridge’s full capability with the slower burning powders.

Is the 6GT cartridge accurate? Definitely. Here is a 5-shot group at 600 yards shot by Dan. This was Alpha 6GT brass, with Hodgdon H4350 pushing Barnes 112gr Match Burner bullets.

And here is a 4-shot, 600-yard group with reformed 6.5×47 Lapua brass, using Varget powder under a Barnes 112gr Match Burner.

6GT Stress Test — Don’t Try this at Home!
Dan and I also did a “destruction test” to see how the Alpha 6GT brass would hold up when competitors push the cartridge to its limits. Please note that this is PRE-PRODUCTION brass and Dan and I probably exceeded max load for the majority of the duration of this test. Using Varget powder, we pushed 115gr DTACs at 2950+ FPS on a pretty hot day. We ran the charge weight up until the bolt was hard to lift.

6GT Cartridge PRS NRL brass 6.5x47 Lapua fire-formed neck-turn project

Using this very hot charge, we were able to get 14 firings before the primer pocket failed. That is pretty solid considering that this brass was a pre-production sample that Alpha said did not meet its primer pocket design requirements. With these results, I think a shooter pushing 110-115 grain class bullets in the low 2900s will get 16 to 20 firings from a piece of brass.

6GT Cartridge PRS NRL brass 6.5x47 Lapua fire-formed neck-turn project

Is the GT here to stay?
All signs are pointing to “Yes”. Dies are readily available from Hornady, RCBS, and Redding. Chamber reamers are being produced by PT&G and JGS that can be purchased through GA Precision.

Alpha Munitions is hard at work getting quality brass to the shooters. Quite a few people have already chambered up 6GT barrels before they even have brass in hand. I think we will see this cartridge go mainstream in PRS/NRL-style competition in 2020. With Alpha Munitions production brass almost ready to hit the shelves, I think we will see a lot more data come in from the field by the end of this year.

The Verdict — The 6GT Is Looking Great So Far
I am really digging the 6GT and the capabilities it offers. It can launch 103gr Vapor Trails at 3000+ FPS or lob heavy 115gr DTACs in the low to mid 2900s comfortably. George Gardner has texted me some pictures of very impressive groups pushing an 115gr DTAC at 3000 FPS with Alliant Reloder 16 (a very temp-stable powder with a burn rate close to H4350). That being said, if a guy wanted to push that type of speed and bullet weight, the 6mm Creedmoor is a better solution in my opinion. So far my “go to” 6GT load is a 112gr Barnes Match Burner at 2900 FPS. My other favorite load is a Hornady 108gr ELDM at 2970 FPS.

I think the down-range performance of the 6GT over a 6mmBR and the 6BR variants will be valuable on those days where shooting conditions are not as perfect. Recoil is about the same as the 6BR variants (6BRA, 6 Dasher etc.), but noticeably less than a 6mm Creedmoor. The extra energy down range will make a spotter’s job a bit easier when targets extend beyond 800 yards.

Forming GT Brass from Lapua 6.5×47
Before the new Alpha Munitions brass was available, I tested the cartridge using 6GT made from parent Lapua 6.5×47 Lapua brass necked-down and reformed. George Gardner walked me through the process of forming 6GT brass out of Lapua 6.5x47L. The process is time-consuming and is a huge PITA even with the correct tools. More detailed instructions can be found on my 6GT thread on the AccurateShooter Forum. READ Forum Thread HERE.

Here is a photo of what the brass looks like going through the forming/trimming process.
Left to right: 6.5×47 Lapua brass, sized with the 6GT bushing die with a .266 bushing, chopped/trimmed and turned, and fired-formed.

6GT Cartridge PRS NRL brass 6.5x47 Lapua fire-formed neck-turn project

The formed-from-Lapua 6GT brass performed well and is a good option if one has the time and desire, but I’ll be moving over to factory Alpha Munitions brass once it is readily available.

6GT Tested at 1000 Yards
After seeing what Tom Jacobs is doing with his benchrest gun running Alpha Munitions brass, there is no doubt the 6GT is plenty capable out to 1000 yards and beyond. I have a feeling the Benchrest and F-Open guys are going to dig this new 6mm cartridge as well, at least for 600 yards. Note, in this photo it appears Shot #5 is under a paster, but that might just be a Ballistic-X software input error, meaning that this is actually a 4-shot group. Either way it is still impressive.

Updated 6mm Creedmoor Load Data from Sierra Bullets

6mm Creedmoor 6.5 Creedmoor load data Sierra Bullets
Sierra recently updated its LOAD DATA for the 6mm Creedmoor. Click image to get latest PDF.

CLICK HERE for Sierra Bullets 6mm Creedmoor LOAD DATA PDF »

Sierra Bullets has recently released load data for the 6mm Creedmoor cartridge, a necked-down version of the 6.5 Creedmoor, a popular PRS, tactical, and hunting cartridge. Sierra has released very comprehensive 6mm Creedmoor load data, covering fifteen (15) different bullets from 55 to 110 grains. NOTE: Hornady-brand brass was used for Sierra’s 6mm Creedmoor load tests, not the newer, stronger Lapua 6.5 CM brass with small primer pockets. Hand-loaders using Lapua 6.5 Creedmoor brass necked to 6mm may have to adjust their loads.

Sierra writes: “As soon as the 6.5 Creedmoor was released in 2007, a 6mm version was being envisioned. After the 6mm Creedmoor demonstrated its worth at 1000 yards it began to catch the attention of Precision Rifle Series (PRS) competitors. The 6mm/6.5 Creedmoor is a great fit for those looking for an AR platform-friendly cartridge. It delivers velocities very similar to the .243 Win and yet fits the AR10 magazine length[.] The 30-degree shoulder makes this a very efficient case and helps prolong case life as well. The 6mm/6.5 Creedmoor works well with powders such as H4350, RE-17, and Ramshot Hunter for heavier long-range bullet weights. Slightly faster powders such as RE-15, Win 760, and Vihtavuori N540 work well with lighter weight bullets.”

100gr Spitzer (#1540)
100gr SBT (#1560)
107gr HPBT (#1570)
110gr HPBT (#1575)

In developing its 6mm Creedmoor load data, Sierra tested a very wide selection of propellants, two dozen overall. For the smaller bullets, fast-burning powders such as Benchmark, H4895, and CFE223 were tested. For the heavier 100+ grain bullets, Sierra tested a selection of medium-burn-rate powders including H4350, Reloder 16, Reloder 17, Varget, and Superformance. Sierra did a very thorough job. We know this information will be welcomed by 6mm Creedmoor shooters.

Don’t know what powder to try first? For the 107-110 grain bullets, if you want best accuracy and low ES/SD, our Forum members recommend Alliant Reloder 16 and Hodgdon H4350. If you are seeking max velocity with the 110-grainer, look at Hodgdon Superformance and Reloder 19.

Here are Sierra’s 6mm Creedmoor Load Data Charts for the 107gr MK and 110gr MK. There are a half-dozen other tables for lighter-weight bullets.

6.5×47 Tactical Tack-Driver — The Non-Creedmoor ‘Six-Five’

6.5x47 Lapua Tactical Rifle Ryan Pierce Brux Barrel H4350 Berger Hybrid

A couple seasons back we published our comprehensive 6.5×47 Lapua Cartridge Guide, researched by the 6.5 Guys. In case you’ve been wondering what kind of accuracy is possible for a tactical-type rifle chambered for this mid-sized cartridge, check out this tack-driver built by gunsmith Ryan Pierce. That’s a mighty impressive 0.206″ five-shot group fired with Berger 140gr Hybrids using a Brux cut-rifled barrel. The powder was Hodgdon H4350, a very good choice for this cartridge.

6.5x47 Lapua Tactical Rifle Ryan Pierce Brux Barrel H4350 Berger Hybrid

Ryan reports: “Here is a 6.5×47 I built for a customer. It features a trued Rem 700 action, Brux 1:8″ Rem varmint-contour barrel, Mcmillan thumbhole stock, Surgeon bottom metal, and 3-port muzzle brake. The customer’s preferred load is the same that has worked in the last couple dozen 6.5x47s I’ve built: 41.1-41.3 grains of H4350 with 140 hybrids .050″ off the lands. This should run about 2810-2815 fps from a 26″ barrel. The 3.128″ refers to length of a loaded round from the base to ogive including the Hornady ogive comparator tool.”

6.5x47 Lapua Tactical Rifle Ryan Pierce Brux Barrel H4350 Berger Hybrid

Yep, It Measures Up…
Lest anyone dispute Ryan’s measurement of this group (the internet is full of nay-sayers), 0.206″ is EXACTLY what we got when we measured this group using OnTarget software. See for yourself:

IMR Enduron Powders — Accurate, Temp Stable, and Versatile

IMR Enduron Powder 4166 4451 7977

Have you tried IMR Enduron powders yet (IMR 4166, 4451, 4955, and 7977)? We’ve been impressed with what we’ve seen. IMR’s line of Enduron extruded powders offer excellent temp stability, reduced copper fouling, and good load density for many popular cartridges (such as .223 Rem, 6mmBR, .308 Win, .30-06, 300 WSM to name a few). Some of our Forum members have reported excellent results with IMR 4166 in the 6mmBR, Dasher, 6.5×47 Lapua and .308 Win. One member wrote: “in my 6.5×47… 4166 gives speeds and accuracy pretty much exactly the same as Varget.” And other shooters have observed reduced copper fouling with Enduron series powders, so IMR’s Enduron anti-fouling chemistry does seem to work.

IMR Legendary Powders provided this summary of Enduron Properties:

Varmint hunters, big game hunters, match shooters and military snipers all seek powders that are insensitive to temperature changes. These powders all have it. This translates to point of impact and group size remaining the same, no matter what temperature conditions prevail. Another huge benefit is an additive that prevents copper fouling from building during dozens of rounds being fired. Here the advantage is top accuracy for longer periods of time, and less cleaning time.

IMR Enduron Powder 4166 4451 7977

A third major accomplishment with this technology is ideal load density. Experienced reloaders know that a case-filling load often delivers the most uniform velocities and best accuracy. We see this in popular match cartridges such as the 6PPC, 6mmBR, 6BRA, 6.5 Creedmoor and .308 Win. These new Enduron powders offer excellent “full case” load density for the most commonly used cartridges with popular bullets.

These three powders, IMR 4166, IMR 4451 and IMR 7977, are environmentally friendly by not having any ingredients harmful to the environment. Add to that, the three of them cover the most popular cartridges from .204 Ruger up to the mighty 500 Nitro Express, and the handloader “has it all”.

Hodgdon 2019 Annual Manual with 5000+ Loads Released

Hodgdon Annual manual relaoding 224 valkyrie .308 win varget h4350

Hodgdon has released its 2019 Reloading Manual, the 16th Annual Edition of this valuable reloading resource. This new manual contains data for Hodgdon, IMR and Winchester Smokeless Propellants in more than 5,000 loads, with updates for 17 rifle and pistol cartridges. Using this resource, handloaders can now find data for the new 224 Valkyrie and 6.5 PRC cartridges. Along with comprehensive load data, the 2019 Hodgdon Annual Manual offers authoritative articles by leading gun and outdoor industry writers, working with the editors of Shooting Times magazine.

“The Annual Manual is our printed yearly update for the ardent handloader,” said Ron Reiber, lead ballistician for Hodgdon. “We believe one of our competitive advantages is providing cutting-edge data on all our propellants. Our customers know they can look to Hodgdon to be first to supply this information on hot, new cartridges and newly-introduced powders.”

CLICK HERE to order the 2019 Hodgdon Annual Manual from the Hodgdon website for $12.99 (shipping included). You can also purchase the Annual Manual wherever popular magazines are sold.

H4350 and Varget In Stock Now at Many Vendors

In 2017 Hodgdon celebrated its 70th Anniversary. At SHOT Show 2017 talked with Chris Hodgdon. Chris was proud to note that his family-owned company is now marked its 70th year in business. The company has been very successful, but sometimes that means supply can’t catch up with demand with some of the most popular powders, such as Hodgdon H4350, which is extremely accurate and also temp-stable. Chris said: “Getting more H4350 to our customers is one of our top priorities. With the booming popularity of the 6.5 Creedmoor and other similar cartridges, there is a lot of demand for that powder.” Supply has definitely increased this year. Yes, H4350, in both 1-lb and 8-lb containers, is in stock right now at Bruno’s, Graf’s, Midsouth, and Powder Valley.

Hodgdon Reloading guide 2017 Midsouth

Hodgdon IMR Varget XBR 8208 SHOT Show Chris Reloading GuideWe also discussed the continued popularity of Varget, which also became more readily available this year. It is still one of the very best choices for a wide variety of cartridges, including the .308 Win (just look at the groups on our X-Max for Xmas story). Chris said that Varget users may also want to try IMR 8208 XBR. Chris observed: “I think IMR 8208 XBR is one of the very best powders we make. It is accurate, temp-stable, and it meters very well because the kernels are very small. The guys who try 8208 have been very happy.”

We concur with Chris — we’ve used 8208 XBR in a .308 Win and it shot exceptionally well. It is definitely “match-ready” powder for cartridges that like a medium burn-rate powder, such as the .308 Winchester, 7mm-08, and 6mmBR Norma.

Alliant Reloder 16 — Great Powder for Match Cartridges

Reloder Reloader 16 Alliant Powder Propellant Bofors TZ temperature stability temp stable H4350

Do You Like H4350? Then You Should Try Reloder 16 — It Is Accurate and Temp Stable
Alliant Reloder 16 is used now by many top shooters for cartridges that work well with Hodgdon H4350. In fact, we’d say that Reloder 16 is the best substitute for H4350 on the market. Alliant’s RL 16 is very temp stable, offers good velocity, and the accuracy is top tier. Some guys report slightly better accuracy than H4350 in the .284 Win, .260 Rem, 6.5 Creedmoor, 6mm Creedmoor, and 6XC cartridges. If you currently use H4350, you should definitely give Alliant Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.

Alliant powder Reloader Reloder 16 RL16 load data 6.5 Creedmoor .243 Win WinchesterThis is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. As a result, Alliant’s Reloder 16 offers truly outstanding temperature stability.

Match and Hunting Cartridge Applications:
Alliant tells us that Reloder 16 “is ideal for traditional hunting cartridges, such as .30-06 Springfield and .270 Winchester, as well as 6.5mm target loads and tactical applications wherein temperature stability is required.” We also think the powder will work well in these popular match cartridges: 6XC, 6mm Creedmoor, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, .260 Rem, .284 Win, and .300 WSM. For example, Alliant’s Reloder 16 Load Data Page shows a 2932 FPS load with Berger 130 grain Hybrid bullet in the 6.5 Creedmoor.

6.5 Creedmoor Load Data with Popular Powders

Nosler 6.5 Creedmoor load data PRS Reloder 16 RL 17 H4350 Varget IMR 4895

We’re told the 6.5 Creedmoor is now the best-selling chambering in new bolt-action rifles sold in the USA. Accurate, versatile, with moderate recoil, the 6.5 Creedmoor serves hunters, paper punchers, and PRS shooters equally well.

As part of its online Load Data Center, Nosler offers 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. GET ALL 6.5 Creedmoor Load Data.

CLICK HERE for RifleShooter.com barrel cut-down velocity test.

According to the Sierra Load Manual: “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.”

Alliant Reloder 16 — Great Powder for Match Cartridges

Alliant Reloder 16 is used now by many top shooters for cartridges that work well with Hodgdon H4350. In fact, we’d say that Reloder 16 is the best substitute for H4350 on the market. Alliant’s RL 16 is very temp stable, offers good velocity, and the accuracy is top tier. Some guys report slightly better accuracy than H4350 in the .284 Win, .260 Rem, 6.5 Creedmoor, 6mm Creedmoor, and 6XC cartridges. If you currently use H4350, you should give Alliant Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.

This is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. As a result, Reloder 16 offers outstanding temperature stability.

Reloder Reloader 16 Alliant Powder Propellant Bofors TZ temperature stability temp stable H4350

Match and Hunting Cartridge Applications:
Alliant tells us that Reloder 16 “is ideal for traditional hunting cartridges, such as .30-06 Springfield and .270 Winchester, as well as 6.5mm target loads and tactical applications wherein temperature stability is required.” We also think the powder may work very well in these popular match cartridges: 6XC, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, .260 Rem, .284 Win, and .300 WSM. For example, Alliant’s Load Data Sheet shows a 2772 FPS load with 142gr SMKs in the .260 Rem.

Powder Temp Stability — IMR Enduron vs. H4350 and Varget

powder gunpowder temperature sensivity temp stability Hodgdon Extreme Varget H4350 IMR Enduron 4451 4166

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.

CLICK HERE to Read Full Powder Temperature Stability Test on Precision RifleBlog.com.

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.

Magnetospeeed LabRadar chronograph chrono powder gunpowder temperature sensivity temp stability Hodgdon Extreme Varget H4350 IMR Enduron 4451 4166

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:

Magnetospeeed LabRadar chronograph chrono powder gunpowder temperature sensivity temp stability Hodgdon Extreme Varget H4350 IMR Enduron 4451 4166

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°.

PRB’s testers talk about those things, provide a few other insightful views of the data, and discuss tools that can help you manage temp/muzzle velocity in the field in their full post.

According to the Sierra Load Manual: “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.”

Smarter Shooter: Keep Your Ammo Cool on Hot Summer Days

Heat Map USA color chart

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.

Ammo cool storage

Bosch Insulated tool caseTo 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.”

Powder Heat Sensitivity Comparison Test

Cal Zant of the Precision Rifle Blog has published a fascinating temp-stability 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 new Enduron line of propellants.

CLICK HERE to VIEW FULL TEST RESULTS

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.

At Long Last — Hodgdon Shipping H4350 Powder This Week

Hodgdon H4350 Australia powder 6XC 6.5 Creedmoor
Say Hallelujah. These are pallets of Hodgdon H4350, something that’s been very hard to find recently. Check with Bruno’s, Graf’s, Midsouth and Powder Valley very soon.

Hodgdon H4350 has been the Holy Grail of reloading powders — highly desired but near impossible to find. For many popular cartridges such as 6XC, 6.5×47, 6.5 Creedmoor, and .260 Remington, H4350 has been the powder to beat — the “gold standard” for accuracy, low ES/SD, and temp stability. Unfortunately, H4350 has been in very short supply for the last couple of years. Major vendors such as Grafs.com, Midsouth and Powder Valley have been back-ordered for a long, long time.

But now that may change. Hodgdon has received a very large supply of H4350, and has started shipping pallets of the popular powder this week. The photo above was taken May 9, 2017. Hodgdon announced: “We have a lot of powder going out the door most days, but we have some special powder going out again this week. This should be on your local reloading shops’ shelves in the next couple weeks. Reloaders, rejoice!” If you’re in need of H4350, we recommend you contact your favorite shooting shop or online distributors soon. And guys — buy what you need, but don’t horde. Leave some for other shooters.

Powder Comparison Test: H4350 vs. IMR 4451

Hodgdon H4350 IMR 4451 temperature powder test

Many Forum members have been looking for a good substitute for Hodgdon H4350 powder, which remains hard-to-find in many parts of the country. One of the best alternatives is IMR 4451, part of IMR’s new Enduron line of powders. Last year, top F-Class shooter Rick Jensen did a comparison between H4350 and IMR 4451, shooting the two powder in a wide range of temperatures. His data suggests that both powders show good temp stability.

Powder Comparison Test: H4350 vs. IMR 4451

Rick Jensen, Captain of the U.S. F-Open Rifle Team, has tested some of the new IMR 4451 powder. Rick and other team members were looking for a good powder that could replace Hodgdon 4350 which is difficult to obtain currently. The makers of IMR 4451 claim that it is not sensitive to temperature and that it delivers competitive accuracy. So far, Rick’s tests, done with a .284 Winchester and 180gr Berger Hybrids, appear to confirm those claims. Rick posts:

“I did a little informal powder comparison of H4350 versus the new IMR 4451. Rifle used was a Kelbly Panda with a 30″, 1:8.75″ twist 5R Bartlein barrel [chambered in .284 Win]. All charge weights were 50.0 grains using CCI BR2 primers. I was very impressed with this new powder and I believe it to be equal to H4350 as far as temperature sensitivity.

I did not test for accuracy but I will tell you my groups were pretty much equal between the two and all were in the .2-.3 MOA range. I will defiantly be shooting more of this powder in the weeks to come, assuming the supply chain will allow. It looks very encouraging to finally have a alternative to H4350 that we might actually be able to buy.”

Chronograph Results with Temps from 23° F to 101°
Here are chronograph results of a comparison test between IMR 4451 and H4350. Rick’s rifle was cleaned and allowed to cool between each test. Five fouling shots were fired before each test. Important: Note that for both Test #1 and Test #2, the powder order is reversed in the mid-temp fields (IMR 4451 first, then H4350). For the low and high temp entries, H4350 is listed first.
