IMR Classic
IMR Red
IMR described Red as an efficient, clean-burning 12-gauge target powder that also suits lead-bullet handgun target loads, including competition and reduced cowboy-action loads.
Discontinued. Canisters still circulate, but the maker no longer produces it — and load data for it may be withdrawn or archived.

Introduced by IMR in late 2016 as part of a five-powder family (Target, Red, Green, Unequal and Blue) marketed as REACH-compliant 'green technology' propellants. Discontinued. Hodgdon no longer lists this powder among current IMR products and it does not appear on Hodgdon's current relative burn rate chart.

Verify the charge, not just the recipe
Good data gets you a safe starting point. It does not tell you what actually went into the case on stroke 340 — a bridged measure, a double charge, a squib. That is what an RCM Laser Powder Check is for.
