Many of Hodgdon’s most popular powders, such as Varget and H4350, have become very hard to find. Shipments sell out as soon as they reach retailers’ shelves. We know our readers and Forum members are concerned about these supply shortages. Why are these powders in such short supply, and what is the prospect for more Varget, H4350, and other Hodgdon powders in the months ahead?

Hodgdon answered these (and other) questions recently in a Q&A post on the Hodgdon Facebook Page. Here are highlights of those Questions and Answers.

HODGDON POWDER UPDATE Frequently Asked Questions

Here are answers to your questions straight from Hodgdon, 1/31/2020:

Q: Why can’t I find Hodgdon powders like H4350, Varget, Retumbo, and H1000?

A: Quite simply, our manufacturing facilities have not kept up with our orders. Additionally, military contracts began specifying Hodgdon powders in the last few years for military ammunition, impacting our supply. With expanded government regulation, shipping explosive and energetic materials has become more challenging, which also impacts available supply. Lastly, rapidly changing consumer preferences for different powder types has impacted both demand and supply. We worked with all Hodgdon providers to resolve open issues and expect powder supply to improve in 2020 as a result.

Varget, H4350, H4831SC, and other ‘Extreme Series’ powders are in very high demand.

Q: Is the shortage of reloading powder being caused by Hodgdon shipping their powder to the ammunition manufacturing companies?

A: While Hodgdon will continue to ship powder as rapidly as possible, we have a significant backlog in demand. Some powders will be in stock more quickly, but we believe it will take much of 2020 to improve availability for all powders. [Editor: In a separate post, Hodgdon stated “We will be sending out large amounts of H4350 starting mid-March.”]

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.

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.

Here are the IMR 4451 fired cases, displayed Left to right, coldest to the hottest (in terms of case temp when fired). All charge weights were the same: 50.0 grains.
