Alliant Reloder 33

A very slow magnum rifle powder formulated for long-range .338 Lapua and other large magnum rifle cartridges.

A specialist: very slow, aimed at .338 Lapua Magnum and the big .338 ultra magnums for long-range shooting. In those cases it does what nothing faster can, and Alliant's emphasis on lot-to-lot consistency matters when a small velocity shift is a miss at distance. Outside very large capacity cases it is useless — poor fill, incomplete burn, erratic ignition. Expect the usual overbore consequences in barrel life and be honest with yourself about whether you need this much powder.

  • .338 Remington Ultra Magnum
  • long-range heavy magnum loads

Typical cartridges.338 Lapua Magnum, .338 Remington Ultra Magnum

Grain shape

Long extruded grains with a very thick web; that wall is what makes the burn last long enough to be useful behind a heavy .338 bullet, and it only pays off with enough case volume and barrel length to use it. Grains this long bridge badly — drop tube and trickle.

Why geometry decides burn rate more than chemistry does: Shape Is the Product.

Alliant emphasises superior lot-to-lot consistency. Suited only to very large capacity cases.

Burn rate

Second-slowest in Alliant's line, ahead only of Reloder 50.
