Powder Burn Rate Comparison Table — Download HERE

Hodgdon IMR Winchester Burn Rate Powder speed table relative table chart

Day after day, one of AccurateShooter’s most-visited web pages is a reference guide featuring a comparative burn rate chart, ranking powders from fastest to slowest. Compiled by Hodgdon Powder Co., this Burn Rate Chart displays the relative burn rates of 163 different powders. Here is the latest table, released by Hodgdon in November of 2019.

You’ll want to download this Powder Burn Rate Table. This table shows the latest IMR powders including the Enduron series (IMR 4166, 4451, 4955, 7977), highlighted in green. This 163-entry comparison table provides vital information for hand-loaders. Note — this invaluable chart is not limited to Hodgdon and IMR propellants. This burn rate chart ranks powders from eight major powder-makers: Accurate, Alliant, Hodgdon, IMR, Norma, Ramshot (Western), Vihtavuori, and Winchester.

This chart provides useful information for all hand-loaders. When doing load development, and testing one powder versus another, it’s generally wise to choose propellants that share the same relative burn rate, as least for starters.

NOTE: Hodgdon powders are blue, IMR Enduron powders are green, IMR standard powders are yellow, and Winchester powders are red. DOWNLOAD Chart HERE.

SHOT Show Day One — New Products

Kelbly Rimfire Anschutz  PRS F-TR trainer

Here are new Rimfire Cross-Trainer Rifles from Kelbly’s. These feature Anschutz .22LR rimfire actions in full-size, competition stocks. This is a great offering for F-TR, prone, and long-range competitors looking to train with less expensive rimfire ammo. Kelbly’s will sell these as complete rifles with rimfire actions bedded in fiberglass stocks.

SHOT Show, held every year in Las Vegas, is the largest gun show in North America. Thousands of exhibitors showcase hosts of new products — rifles, pistols, shotguns, optics, stocks, reloading tools, bullets, brass, powders, hunting accessories and much more. This is the ultimate “candy store” for gun guys, with literally “miles of aisles” and countless products on display. Here are some of the more interesting items we saw during Day One of SHOT Show.

Howa HCR Chassis Rifle
All decked out in a Camo Cerakote finish, the new Howa HCR Chassis rifle was an eye-catcher. Designed for PRS-type competition, the HCR features a modular aluminum stock with a separate buttstock section with adjustable comb and adjustable length of pull. The HCR will be offered in four chamberings: .223 Rem, .243 Win, 6.5 Creedmoor, and .308 Win. There will be standard and heavy barrel options with 20″, 22″, and 24″ lengths. The rear of the stock accepts AR-type furniture (for those guys who need to customize). This new rifle will be sold in Black or Multicam Cerakote finishes. A package will be offered with Nikko Stirling 4-16x50mm scope and EGW 20-MOA, one-piece base and rings.

New Viper PST Gen II Scopes from Vortex
The versatile Viper PST series can work for many disciplines — Target Shooting, 3-Gun, Hunting, or Precision Long Range. The new second generation PSTs offer many improvements, with four new models for 2017: 1-6x24mm, 2-10×32mm, 3-15×44mm, and 5-25×50mm: Vortex offers a wide magnification range with its 2017 line-up of Viper PSTs. These new scopes offer tall tactical turrets and side-focus parallax adjustment with integrated illumination. To ensure reliable return-to-zero, all new models feature the patented RZR Zero Stop from the Razor HD 5-20×50 riflescope. Reticles include Vortex’s new EBR-4 and EBR-2C with MOA or MRAD stadia to match your turrets. First Focal Plane reticles are available on select models.

Savage AR10-Type MSR in 6.5 Creedmoor and .308 Win
Our friends Ed and Steve (aka the 6.5 Guys) visited the Savage booth to take a look at the new Savage MSR Long-Range model, an AR10-type modular semi-auto rifle with a Magpul PRS Gen3 buttstock. The 6.5 Guys report: “Savage’s new MSR 10 Long Range Rifle is chambered in 6.5 Creedmoor or .308 Win. It appears to be a terrific option for those wanted to compete in the new PRS Gas Gun Series. It is built on a compact frame with a non-reciprocating side-charging handle that is particularly useful for left-handed shooters. The Blackhawk AR Blaze™ two-stage target trigger was light and crisp. It features an upgraded Savage barrel, with 5R rifling and a Melonite QPQ finish.

New Accurate No. 11FS Low-Flash Pistol Powder
Western Powders showcased a new Accurate powder that delivers 90% less muzzle flash, while still offering good consistency and accuracy. Accurate No. 11FS (for Flash Suppressed) is designed for magnum pistols, and small rifle rounds such as the Hornet. The advanced flash-suppressing formula dramatically reduces muzzle flash in many large pistol cartridges. Notably, this Accurate 11FS was specifically designed to work with the .300 Blackout cartridge.

Enhanced Bluetooth Connectivity for Kestrel
At the Kestrel booth, we learned that Kestrel will be offering an enhanced LiNK Bluetooth low-energy enabled protocol that will allow wireless connections with a greater variety of devices. This will allow Kestrels to share data with Bushnell, Wilcox, and Vectronix Laser Rangefinders, Steiner LRF Binoculars and many other devices. This kind of connectivity allows Kestrel windmeters to be more versatile than ever.

Big Boomer Brass from Peterson Cartridge
For those who shoot the .408 or .375 Cheytac, sourcing top-quality brass has been a challenge in the past. That’s changed with the introduction of premium Cheytac brass from Peterson Cartridge Company. Along with the new Cheytac brass, Peterson produces quality casings for other large rifle cartridges including: .338 Lapua Magnum, .300 Winchester Magnum, and 7mm Rem Magnum. Peterson’s brass offerings for smaller match cartridges include: 6.5 Creedmoor, .260 Remington, .308 Win Palma (Small Primer Pocket), and .308 Win Match.

Powder Storage Q & A — What Are Signs of Problems?

Western Powders Blog SAAMI Storage

Western Powders (vendors of Accurate, Norma, and Ramshot powders), publishes a Blog that covers all aspects of hand-loading and rifle maintenance. Recently the Western Powders Blog published a 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.

Load Data for Accurate LT-30 and LT-32 Powders

Western Powders LT-32 LT-30 accurate powder

Is that target good enough? Yes that’s really five (5) shots. This amazing group was shot, in competition, with 6 PPC cartridges loaded with Accurate LT-32 powder. If you’d like to try out this powder in your rifle, Western Powders has released loading data for the LT series of powders. LT-32 is a good choice if you’re currently using propellants with burn rates similar to Vihtavuori N133 or Hodgdon Benchmark powders. (Caution: NEVER simply substitute loads powder for powder. Always start low and work up when trying a new powder). The other powder in Accurate’s LT series, LT-30, has a burn rate similar to Hodgdon H4198. LT-30 is a superb performer in the 30 BR cartridge. LT-30 also is a good choice for small varmint cartridges such as the 17 Rem Fireball.

New Accurate LT-32 Powder Coming in January

Midsouth Shooters Supply is now taking advance orders for the new Accurate LT-32 Powder, with initial deliveries expected in January 2013. Price for a 1-lb container is $25.12, while an 8-lb jug runs $190.50. Produced by Western Powders, LT-32 is an extruded powder with extremely small kernels (roughly .0275″). This powder is designed to perform like the legendary “T-322″ powders which worked brilliantly in short-range benchrest cartridges, especially the 6mm PPC. Early testers report that Accurate LT-32 meters superbly and is easy to tune. Western claims LT-32 exhibits very low standard deviation. (Photos below by Speedy Gonzalez).

Speedy Says Accurate LT-32 is Very Promising
Benchrest Hall-of-Famer and noted gunsmith Thomas ‘Speedy’ Gonzalez tested the prototype LT-32 powder from Western Powder earlier this year. Speedy stated: “It pains me to say it, but the new LT-32 out-shot my best lots of [the original] IMR 8208 (T-322)”.

Accurate lt32 powder Western

Speedy reports: “I must say that I was quite surprised by the results of my initial testing of the new Western Powder LT-32. Shooting this morning over my Oehler 35P triple screen chronograph yielded some very unexpected results. My best lot of ‘T’ powder continues to exhibit its age as it continues to lose velocity (as it ages). While the new Western LT-32 demonstrated this morning velocities equal to what my old ‘T’ powder used to shoot like 30 years ago.

This new powder goes through the measure like a ball powder. (Note: I have always felt that one of the reasons ‘T’ powder shot so well was due to the fact it measured so well as compared to other powders. This is a definite advantage for us that rely on consistent volume instead of weight.) I will have to shoot it over a season to see if it is as temperature and humidity insensitive as ‘T’, but it looks very promising from what I saw today.

It has yet to be seen if the new LT-32 proves to not be affected by temperature and humidity like the old T-322. But from these short tests it very much mimics my T-322 of old. My ‘T’ powder was always a blessing to me in the fact that when I went to a match I did not have the same problems everyone else was having [i.e. having] to tune up and down over the course of a weekend or week. I got to shoot and concentrate on the conditions instead of making it a tuning competition. It was always kind of funny watching everybody going up and down on their powders trying to accommodate the changes in weather as the days went on. Hopefully this will allow all to become better shooters by being able to concentrate on shooting and not re-turning every time one comes back from the bench.”

Statement from Western Powders

The Accurate LT-32 is an exact copy of the original T-32 manufactured in the same plant and on the same machinery as the original. Lou Murdica has been extensively testing it and he tells us it is the easiest powder to tune that he has seen in 40 years.

Accurate lt32 powder WesternAccording to Lou, the chamber that everybody was using in the 80s will work with this powder. The bullets do not need to be seated way out in order to get more powder in the case. In testing the powder in our Bond Universal receiver against the original “T” powder, SDs were about 30% lower with the new powder versus the “T” powder. Lou and Don Nielson donated 16 lbs. of the original T-32 lot of powder for our quality control and that is what the new powder is shot against.

All of our powders are allowed to deviate +3% to -5% in pressure from the quality control lot except LT-32 which we cut the deviation percentages in half in order to have the best lot to lot consistency in the industry for this powder[.] We developed this powder specifically for the 6mm PPC and it is QC’d in the 6mm PPC.

NOTE: Accurate LT-32 should also be available from PowderValleyInc.com in mid-to-late January 2013. Listed Prices are: $24.10 for 1 pound and $182.00 for 8 pounds.
