Alliant Pistol/Shotshell
Alliant Unique
Alliant's most versatile powder, covering a wide span of shotshell gauges and essentially all common handgun calibers.
The most versatile powder in American handloading and it has been for a century: every common gauge, essentially every common handgun cartridge, mid-range revolver loads, light rifle work. If you can only own one powder for a mixed cabinet, this is the honest answer. Its famous flaw is real but conditional — at light pistol charges it smokes like a muzzleloader and leaves sooty fouling, and it cleans up substantially when run at the pressures it was designed for. Loaded soft in .38 Special it is filthy; loaded properly in .44 Magnum, .45 ACP or a field shotshell it is clean and thoroughly consistent.
- mid-range .45 ACP and .38 Special
- mid-range .44 Magnum
- 12 gauge field loads
- 20 gauge and 28 gauge hunting loads
- general-purpose pistol loading

Grain shape
Coarse cut circular flake sitting mid-ladder — the web is thick enough to place it squarely between the target powders and the magnum ones on the same chemistry. Big flakes bulk well and fill a case, but they bridge and shear in a tight measure, so thrown charges spread more than a fine flake or a spherical.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Alliant describes the current formulation as cleaner burning than the original and says it works with most hulls, primers and wads. The handgun and shotshell product pages point at the same load data set.
Burn rate
The middle of Alliant's range; the reference point most shooters place other powders against.

What reloaders say about it
Unverified community anecdote. The following is a summary of what handloaders report in public forums. It is not manufacturer information, it has not been tested, it may be wrong, and it contains no load data by design. Treat it as colour, not guidance.
Unique is the archetypal 'dirty but beloved' powder. The near-universal report is heavy smoke and sooty fouling at light pistol loads, with an equally consistent community explanation: it burns much cleaner when run at higher pressure. Users who load it hot, or in magnum revolver and shotshell applications, report no complaints.
- heavy smoke and soot at light loads, described as muzzleloader-like
- reported to clean up substantially at higher pressures / upper end of published ranges
- long-standing versatility across pistol, revolver and shotshell
- some users dispute the dirty reputation entirely, tying it to how it is loaded
Availability: Treated as an old standby that is usually findable, though not immune to the general price escalation.
Reported cautions:
- Some of the smoke users attribute to the powder is attributed by other users to lead or coated bullets — the community itself does not agree on the cause.
Consensus level: widely held. Drawn from thread 1.
