You are not going to find Unique and you will be lucky to find Universal.

I am a fan of ... VV N-340
And Powder Valley has N340 along with N320/N330:
I always thought of BE86 as an updated version of Bullseye.
No, no, no.
"BE-XX" formulation has to do with small powder granule/flake type/size and not burn rate with "XX" likely being the year of introduction.
Bullseye is fast burning powder on par with Red Dot/Promo, WST, Clays and "downloads" below start charges well for very light recoiling and lower velocity "bullseye match" loads that just need to make holes on paper to require lighter recoil springs.
BE-86 is slower burning powder on par with Unique, Universal, Power Pistol, WSF and do not "download" well below start charges but better suited for higher velocity loads.
This is what Paul from Alliant Powders said about BE-86 -

"No, Power Pistol and BE-86 are most definitely not the same. Nor is BE-86 just Power Pistol with flash suppressant added. Power Pistol is the canister version of BE-84, which is slower burning than BE-86, which is the canister version of BE-86. They are not that far apart, and the formulations are identical, but the deterrent percentage is higher for Power Pistol (BE-84) compared to BE-86."
