The powder shelf, spring *2026*
Walk into a Canadian reloading shop this week and most shelves are full. A few specific ones are not. The empty shelves trace back to Australia, not Ottawa. Here is what is short, what to substitute, and what a newer reloader should carry away.
Walk into Sporteque in Granby, or Higginson Powders north of Toronto, or the powder wall at Rangeview Sports, or Wolverine Supplies in Virden, this week. Most of the shelves are the way a Canadian reloader expects them to be. The Vihtavuori lineup is stocked. The Alliant Reloader series is stocked, RL-16 and RL-17 in particular. The IMR Enduron powders are in reasonable rotation. Most of Hodgdon's catalogue is moving normally. And then there are four specific cans that are thin, back-ordered, or gone.
The four are H4350, H4895, Retumbo, and Trail Boss. If you are new to reloading and have been reading load data for 6.5 Creedmoor, .308 Winchester, .300 Win Mag, or any of the standard reduced-recoil plinking builds, those four names are going to sound familiar in an unpleasant way. They are the Hodgdon powders that happen to sit at the burn rates a lot of popular cartridges land on. They are also the ones currently feeling the squeeze.
The squeeze is not a Canadian story. It is an Australian one, and a supply one, and the difference matters.
What is actually short, and what is not
The industry reporting in the last thirty days - tracked across Shooting Industry Magazine, the weekly roundups at TheGunBlog.ca, and the ongoing CGN component availability threads - lands on a short list. H4350 and H4895 are thin across Canadian retailers. Retumbo and Trail Boss are harder still. Varget and H1000 are currently in better shape but both come from the same plant and sit one supply cycle away from the same constraint. That is the accurate read as of late April.
What is currently easy to source on a Canadian bench: the entire Vihtavuori N100 and N500 series, with N150, N160, N555, and N570 all in reasonable stock. Alliant RL-16, RL-17, RL-26, and RL-33 are stocked. IMR 4166 and IMR 8133 are available. Hodgdon's own non-ADI powders - the ball powders, CFE 223, CFE BLK, and most of the shotgun line - are moving normally. Winchester ball powders are in rotation. This is not 2021 all over again. It is a narrower event.
If you handload for a single popular cartridge and you have been planning your ladder around H4350 specifically, the affected list is the whole of your problem. If you handload for a range of cartridges and you have been working across two or three powder brands already, you have barely noticed.
Why Australia
Hodgdon does not make most of the powders that carry the Hodgdon label. The "Extreme" series - the line that covers H4350, H4895, H4831, H4831SC, H1000, Retumbo, Varget, H50BMG, Trail Boss, and several others - is manufactured by Thales Australia, the Australian defence company that owns what used to be ADI Munitions. Hodgdon licenses those powders for North American distribution. On the Australian side of the same relationship, the same cans are sold domestically under the ADI brand with an AR designation: AR2206H is H4895, AR2208 is Varget, AR2209 is H4350, AR2225 is Retumbo.
This is not new. It has been the arrangement for decades. What is new is that Thales Australia has been running under capacity pressure, and when the plant is constrained, Hodgdon's North American allocation tightens first. Canadian retailers sit at the end of a longer logistics chain than American ones and are usually the last to see stock return after a constraint lifts. The spring 2026 thin-shelf pattern is the visible result of that arrangement under strain, not the result of any Canadian regulatory action.
Worth stating plainly because it needs to be: this is a supply story. It is not a policy story. There is a lot going on in the Canadian firearms regulatory file right now, and it is easy, when any component runs short, to read the shortage into the politics. In this case, the politics have nothing to do with it. H4350 is harder to find on a Canadian shelf because a particular plant in New South Wales is not running at full capacity, and for no other reason.
What this means if you are new to the hobby
If you are a couple of years into your PAL and you have just started reading load manuals, three things are worth carrying away from the pattern.
First, do not panic-buy. The 2021 primer drought trained a reflex into the community that was rational at the time and counterproductive now. A newer reloader who clears the shelf of H4350 because the rumour mill is running hot is guaranteeing the shortage continues. Buy the one or two cans you need for a load development cycle and the immediate follow-on batch. Leave the rest for the next person. The hobby runs on a norm of self-restraint under supply pressure, and that norm is worth honouring.
Second, substitute thoughtfully. If your 6.5 Creedmoor plan was H4350 and H4350 is not on the shelf, the live alternatives for that cartridge are well documented. Alliant RL-16 and RL-17 are in stock and sit at the correct burn rate. Vihtavuori N150 and N555 are both supported in published load data for 6.5 Creedmoor. IMR 4166 is an option. None of these are exotic. All of them have been loaded by competitive shooters for years. The rule is simple. Start from a fresh mid-range charge for the new powder and work up with a ladder, not from the top of your old sheet written against a different can.
Third, learn the burn rate chart before you learn the brand names. H4350 is not magical. It is useful because its burn rate sits near the ideal window for a cluster of cartridges from .243 Winchester through 6.5 Creedmoor through .260 Remington. The powders that crowd that window on the Hodgdon and Western Powders burn rate charts - IMR 4451, Alliant RL-16 and RL-17, Vihtavuori N150 and N555, Accurate 4350 - are the shortlist of live substitutes. Understanding where a powder sits on the chart is more durable than memorizing which brand was on the shelf the week you started.
Where Canadian retailers sit right now
A Canadian retailer snapshot is always a moving target and any claim I make here has a shelf life measured in days, not months. Treat this as the pattern I am seeing on the 24th of April. Verify against the current retailer product pages before buying.
The consistent read across Canadian reloading retailers is that the affected Hodgdon Extreme powders are either back-ordered, listed as limited, or absent entirely, while the non-ADI portion of the Hodgdon catalogue, the Vihtavuori lineup, the Alliant Reloader series, and the IMR Enduron series are all moving. The pattern holds across the retailers that matter most to Canadian precision reloaders:
Insert a native bulleted list block. Type each of the following as its own bullet:
- Sporteque (Granby, QC) - deep Vihtavuori inventory. Hodgdon Extreme is partial.
- Higginson Powders (Roseneath, ON) - the default reference for powder availability in Canada. Partial shelves on H4350 and H4895. Retumbo and Trail Boss largely gone.
- Rangeview Sports (Newmarket, ON) - mixed Hodgdon inventory, full Vihtavuori and RL shelves.
- Wolverine Supplies (Virden, MB) - full Alliant and Vihtavuori. Hodgdon Extreme thin.
- Reliable Gun (Vancouver, BC) - usual precision rifle ecosystem. Hodgdon Extreme reflects the same pattern.
- Barton's Big Country (Ardrossan, AB) - Prairies coverage. Hodgdon Extreme mirrors the national pattern.
None of these retailers is rationing at the shelf level in the reports I have seen. You can buy what is there. You cannot buy what is not there. That distinction is what separates this supply event from 2021, when shelves emptied because buyers emptied them.
The bench response
On a working bench, the squeeze looks like this. A newer reloader pauses load development on a specific cartridge until the planned powder is back in reach. Or shifts to a different powder for that cartridge, accepting the ladder work that comes with the substitution. Or keeps shooting factory ammunition for the short term while the supply catches up. All three are reasonable. None is a crisis. All of them describe a hobby operating inside its own tolerances.
On my own bench, the working rule at the moment is simpler still. Finish the loads that are already developed against a powder I have on hand. For cartridges without a developed load yet, start against a powder that is easier to resource this year and recognize that the plant in New South Wales will catch up eventually. A bench that runs across more than one cartridge runs across more than one powder anyway. Flexibility was the point before the squeeze and remains the point after it.
What to watch
A few signals, in the order they tend to change state:
Insert a native bulleted list block. Type each of the following as its own bullet:
- Thales Australia's 2026 sporting-propellant production notes, when published
- Hodgdon's own distributor communications out of Kansas, which have been quiet but usually move first in the cycle
- Canadian distributor ETAs on H4350 specifically, which is the bellwether for the rest of the Extreme line in this market
- Heavier retail rotation of the live substitutes, especially RL-16, RL-17, N150, and N555, which shows the community absorbing the substitution
- The next TheGunBlog.ca weekly roundup and the next Shooting Industry Magazine supply piece, either of which is likely to update the status
A Canadian handloading community that navigated the 2013 primer scare, the 2020 Order in Council, the 2021 primer drought, and a decade of other shocks can absorb a quarter of reduced Australian powder allocation without losing its footing. The shelf will restock. The burn-rate chart is still the same shape it was last year. What a newer reloader should carry away from the spring 2026 pattern is narrower and more useful than the usual doom read. Supply and policy are two separate files, they run on separate timelines, and this one is supply. The bench keeps moving.
