No such thing. Bullseye was used in 45acp, but I'm not aware of the Military using Unique.
Never say no such thing.
2 loads for 230 grain ball 45 ACP developed for military use are attributed to Julian Hatcher, Bullseye and Unique. There was also a powder designated SR80 that was used.
SR-80 was the predecessor of SR-4759. A powder made in relatively large diameter, but stubby, stick form. Primary use was in reduced loads in large capacity cases. I guess it could've been used .in .45's but I can think of a lot of much better powders both then and now.
