Have inflation (and supply chain shortages) affected the price of powder? You bet. Probably WAY more than you could imagine. Forum member “Two Time HM LR” posted this interesting photo (above) showing Hodgdon 8-lb powder prices from 1978, as sold by O.K. Weber in Oregon. Prices have risen over 1000% since then.
Eight Pounders under $45.00 in 1978
Now the prices — $20 to $44 — may not get your attention at first. But take note that these numbers are for EIGHT pound containers. Yep eight-pounders were all under $45! For example, H4895 was $44 for 8 pounds back in 1978, 45 years ago. And H335 was $20 for eight pounds — that’s just $2.50 per pound!
These days a single pound of a desirable powder such as H4831 might cost $60+ at some stores IF you can find it at all. On Hodgdon’s web site, H4831 powder is priced at $58.99 per pound in April 2024. Using that current $58.99/lb figure, H4831 is now 10.7 times higher than it was in 1978, when H4831 cost $44 for 8 pounds, i.e. $5.50 per pound. [Hodgdon’s current H4831 8-lb price is $403.99, or 9.18 times higher than before.]

“Heck those prices are just about the same as current ones, just a little smaller container now.” — Joe
“I’ve got some H4831 in a can marked ‘WWII Surplus Powder’ with a price tag of $2.75. We’ll never see that again either.” Rick in Oregon
“1978 prices and 2022 income would be nice. Unfortunately that doesn’t work. If you compare prices and income, powder cost about the same. You also have to discount the temporary gouging that we are seeing.” — Tmwinds
“So I used to buy gas for 10 cents per gallon and they’d pump it, check the oil, and clean the windshield.” — Pirate Ammo
One comment suggests that the powder price hike actually tracks general U.S. currency inflation over the last four decades. So perhaps powder price increases are not as bad as they seem, when compared to how all prices have risen since 1978:
“Using H4895 as a comparison basis at $58.50 (list price) in 1978 calculates it to $275 in todays money. Looking at Powder Valley prices it looks like around [$340 in August 2023] for the same item in todays money [a 24% increase in real dollars]. Availability is another issue though and if someone is really needing powder they may well have to pay above suggested retail.” — Drover

The leaves are falling, and that means the rainy season will soon begin in many areas of the country. With rain comes increased moisture in the air, i.e. increased humidity. And that, in turn, can affect how your powders perform by altering their burn rates.
Most shooters realize that significant changes in temperature will alter how powders perform. That’s why you want to keep your loaded ammo out of the hot sun, and keep rounds out of a hot chamber until you’re ready to fire. But there are other factors to be considered — HUMIDITY for one. This article explains why and how humidity can affect powder burn rates and performance.
We’ve all heard the old adage: “Keep your powder dry”. Well, tests by Norma have demonstrated that even normal environmental differences in humidity can affect the way powders burn, at least over the long term. In the Norma Reloading Manual, Sven-Eric Johansson, head of ballistics at Nexplo/Bofors, presents a very important discussion of water vapor absorption by powder. Johansson demonstrates that the same powder will burn at different rates depending on water content.
Powders Leave the Factory with 0.5 to 1.0% Water Content
Johansson explains that, as manufactured, most powders contain 0.5 to 1% of water by weight. (The relative humidity is “equilibrated” at 40-50% during the manufacturing process to maintain this 0.5-1% moisture content). Importantly, Johansson notes that powder exposed to moist air for a long time will absorb water, causing it to burn at a slower rate. On the other hand, long-term storage in a very dry environment reduces powder moisture content, so the powder burns at a faster rate. In addition, Johansson found that single-base powders are MORE sensitive to relative humidity than are double-base powders (which contain nitroglycerine).
Tests Show Burn Rates Vary with Water Content
In his review of the Norma Manual, Fred Barker notes: “Johansson gives twelve (eye-opening) plots of the velocities and pressures obtained on firing several popular cartridges with dehydrated, normal and hydrated Norma powders (from #200 to MRP). He also gives results on loaded .30-06 and .38 Special cartridges stored for 663 to 683 days in relative humidities of 20% and 86%. So Johansson’s advice is to keep powders tightly capped in their factory containers, and to minimize their exposure to dry or humid air.”
Confirming Johansson’s findings that storage conditions can alter burn rates, Barker observes: “I have about 10 pounds of WWII 4831 powder that has been stored in dry (about 20% RH) Colorado air for more than 60 years. It now burns about like IMR 3031.”
What does this teach us? First, all powders start out with a small, but chemically important, amount of water content. Second, a powder’s water content can change over time, depending on where and how the powder is stored. Third, the water content of your powder DOES make a difference in how it burns, particularly for single-base powders. For example, over a period of time, a powder used (and then recapped) in the hot, dry Southwest will probably behave differently than the same powder used in the humid Southeast.
Reloaders are advised to keep these things in mind. If you want to maintain your powders’ “as manufactured” burn rate, it is wise to head Johannson’s recommendation to keep your powders tightly capped when you’re not actually dispensing charges and avoid exposing your powder to very dry or very humid conditions. The Norma Reloading Manual is available from MidwayUSA for $24.99.
Real-World Example — “Dry” H4831sc Runs Hotter
Robert Whitley agrees that the burn rate of the powder varies with the humidity it absorbs. Robert writes: “I had an 8-lb. jug of H4831SC I kept in my detached garage (it can be humid there). 43.5-44.0 gr of this was superbly accurate with the 115 Bergers out of my 6mm Super X. I got tired of bringing it in and out of the garage to my house for reloading so I brought and kept the jug in my reloading room (a dehumidified room in my house) and after a few weeks I loaded up 43.5 gr, went to a match and it shot awful. I could not figure out what was going on until I put that load back over the chronograph and figured out it was going a good bit faster than before and the load was out of the “sweet spot” (42.5 – 43.0 gr was the max I could load and keep it accurate when it was stored in less humid air). I put the jug back in the garage for a few weeks and I now am back to loading 43.5 – 44.0 gr and it shoots great again. I have seen this with other powders too.”
If you have two jugs of the same powder, one kept in a room in your house and one somewhere else where it is drier or more humid, don’t expect the two jugs of the same lot of powder to chrono the same with the same charge weights unless and until they are both stored long enough in the same place to equalize again.

7mm (.284) remains the caliber to beat in F-Class Open Division (though some shooters have had success with .30-Cal short magnums.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr and 184gr bullets to competitive velocities.
The straight .284 Win is an excellent cartridge, quite capable of winning F-class matches. However, in most barrels, it can’t push the 180s at 2900-2950 fps velocity levels*. A lot of barrels will top out at about 2850 fps. That’s where the .284 Shehane comes into play.
The .284 Shehane is a slightly modified wildcat that retains the same 35° shoulder as the parent case. However, by blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with 30-32″ barrels using H4831sc, Vihtavuori N560, or Alliant Reloder 16. (That’s with a reasonably fast barrel. Some barrels are faster than others.)
Norm Harrold Won 2018 F-Class Open Division Nationals with .284 Shehane Rifle
Norm Harrold (above) won the 2018 USA F-Class Nationals shooting a .284 Shehane. Norm’s F-Open rig features a McMillan Kestros ZR stock and Bartlein barrel chambered for the .284 Shehane, which has a bit more case capacity than a standard .284 Winchester. Norm loaded Berger 184gr 7mm bullets in Lapua brass. Norm revealed his load in an Erik Cortina YouTube Video.
F-Class shooter Erik Cortina notes that the .284 Shehane has a velocity edge over the straight .284 Win because it holds more powder: “The Shehane has more capacity than the .284 Winchester. Ryan is using 54.0 grains simply as a fire-forming load. Typical load for a Shehane is around 57.0 grains of Hodgdon H4831 SC.” By blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc, with long barrels.
Forum member Jim Hardy has shot the .284 with great success. He tells us: “In my humble opinion, the .284 Shehane is the best balanced long-range round there is — bar none. Here is why:
You have to shoot a 30 Cal Magnum with a 240gr bullet to equal the performance of most 7mm chamberings with the 180 Berger VLD. With the .284 Shehane, you have a .308 bolt face, medium action, and Lapua brass. You use less powder than the 7 mags, and have great accuracy and ballistics even while fire-forming. The .284 Shehane shoots inside the 6.5 AND the straight .284, the .300 WSM, and the .300 Win Mag with less recoil. What is not to love about the 284 Shehane? It is a no-brainer for long range — F-Class or Prone or 1000-yard Benchrest.”
Amazing Accuracy When Fire-Forming .284 Shehane
If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel! Gun builder Ryan Pierce of Piercision Rifles explains: “Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fireforming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.”
Scotland’s Grant Taylor. who used the .284 Shehane to finish third at the 2009 F-Class Worlds in England says the .284 Shehane is “very accurate with superb vertical spreads at 1000 yards. [This] caliber… has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”
.284 Shehane Showcase — Two Special F-Open Rifles
Jason Cohen’s “We the People” patriotic .284 Shehane F-Class rifle. This rig scored second place in its very first match, a 3×20 at 1000 yards in Wyoming.
Here’s another handsome .284 Shehane F-Open rifle. Owner Jason Cohen explained why he chose the .284 Shehane chambering: “The .284 Shehane has a proven record of accomplishments and that is why I have chosen it. I use Lapua brass (6.5-284 necked-up), CCI BR-2 primers, Hodgdon H4350 powder, and Berger 184gr bullets. All these components have been a successful combination that has worked flawlessly[.]”
The barrel is a Blake Machine 1:8″-twist finished at 32 inches. It was fitted to my action by Dale Woolum of Woolum Accuracy. Dale also threaded the barrel for a Woolum Accuracy tuner. This has proven to be a valuable tool in my load development.
The rifle began its life as a Will McClosky Cerus stock. This was sent that to Bryan Blake at Blake Machine. Jason noticed that Bryan had been adding aluminum rails to the front of Cerus stocks to lower the center of gravity and improve tracking. Jason asked Bryan to fit the stock with forearm rails, shown in the photo below. Bryan did all the stock work and fitted the action, rails, and RAD recoil pad.
The .284 Shehane — Accurate and Forgiving Wildcat
Jason explains why he selected the .284 Shehane chambering: “The .284 Shehane is amazing, very forgiving and not temperamental. Straight .284 or Shehane — you cannot go wrong. I run a 184gr Berger at about 2850 FPS and get great brass life in my other rifles. I usually start to consider tossing the brass around 15 firings. Primer pockets start to get a little looser and the brass seems to need more sizing than the newer brass with less firings.”
.284 Shehane Load Development
Load development for me starts with each new barrel. I screw on the new barrel, fire 25 rounds of whatever I have left over and then clean it. I push out to 600 yards and do a ladder test in round-robin format. I start 0.6 grains lower than my last charge that worked. I work up from that reduced charge weight in increments of 0.3 grains. The paper tells the rest of the story. Once I get something that works well at 600 yards I go back in work around that by 0.1 grains. After that I play a little with seating depth and look for a change. I will occasionally mess with the tuner and tighten things up if possible.
.284 Shehane Raffle Prize Rifle for Team USA

Note the 5″-wide fore-end which is not legal for F-Class. Henry also runs a combo tuner/muzzle-brake.
*Some exceptional barrels chambered in straight .284 Win can reach 2900 fps with the 180s. Ryan Pierce has a 32″ Brux barrel that is delivering 2900 fps with the straight .284. However, Ryan acknowledges that his velocities are not typical: “A lot of .284 Win barrels top out at around 2850 fps with the 180s”.

Scotland’s Grant Taylor. who used the .284 Shehane to finish third at the 2009 F-Class Worlds in England says the .284 Shehane is “very accurate with superb vertical spreads at 1000 yards. [This] caliber… has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”
.284 Shehane Shines in 1K Benchrest Competition Too
The .284 Shehane has won in Benchrest as well as F-Class competition. In 2013, Henry Pasquet won the IBS 1000-Yard Nationals shooting a .284 Shehane. Henry’s Championship-winning rig is shown below. Note the 5″-wide fore-end which is not legal for F-Class. Henry also runs a combo tuner/muzzle-brake.
Amazing Accuracy When Fire-Forming .284 Shehane
If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel! Gun builder Ryan Pierce of Piercision Rifles explains: “Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fireforming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.”
*Some exceptional barrels chambered in straight .284 Win can reach 2900 fps with the 180s. Ryan Pierce has a 32″ Brux barrel that is delivering 2900 fps with the straight .284. However, Ryan acknowledges that his velocities are not typical: “A lot of .284 Win barrels top out at around 2850 fps with the 180s”.

In 2015, IMR® Powder introduced a new line of powders with Enduron® Technology. These powders are designed to address several performance gaps as powder technology has advanced. Here are key features of the Enduron line of propellants:
Enduron powders contain an additive that drastically reduces copper fouling in the gun barrel. Copper fouling should be minimal, allowing shooters to spend more time shooting and less time cleaning a rifle to retain accuracy.
The new Enduron line is insensitive to temperature changes. Whether a rifle is sighted in during the heat of summer, hunted in a November snowstorm or hunting multiple locations with drastic temperature swings, point of impact with ammunition loaded with Enduron technology will be very consistent.
Enduron powders provide optimal load density, assisting in maintaining low standard deviations in velocity and pressure, a key feature for top accuracy.
Enduron technology is environmentally friendly, crafted using raw materials that are not harmful to the environment.
New IMR 4955 for Larger Cartridges
For 2016, IMR has introduced IMR 4955, a new Enduron extruded powder that is a top performer with popular cartridges such as 270 Winchester, 25-06 Remington, 280 Remington, 300 Winchester Magnum and many more. This new powder falls directly between the new IMR 4451 and IMR 7977 in burn speed, providing excellent performance for most big-game cartridges. Like all Enduron Technology powders, IMR 4955 is temperature insensitive, as shown below.
Adding this propellant to the Enduron line filled in an important place on reloading benches. IMR 4955, plus the original three Enduron powders, provide excellent loading solutions for cartridges from 223 Remington to the massive 500 Nitro Express Magnum. Further, in these days of powder shortages, these new Enduron powders can fill a gap by providing comparable performance to select Hodgdon® powders. Specifically, IMR 4955 is a great choice for cartridges that work well with Hodgdon H4831.
IMR Enduron 4955 is available in one-pound (1 lb.) and eight-pound (8 lb.) containers from quality reloading retailers.

Tests Show Burn Rates Vary with Water Content
7mm (.284) remains the caliber to beat in F-Class Open Division (though some shooters have had success with .30-Cal short magnums.) With a standard .284 Winchester, or better yet, a .284 Improved, you can drive the high-BC Berger 180gr and 184gr bullets to competitive velocities.
