6.5 grains Unique was/is??? the 230 grain FMJ factory duplication load. Roughly same with 225/230 LRN cast.
1970 +/- Lyman 44 data and accuracy loads.
50 years ago, HaHa, 6.5 Unique was the go to loading for a box stock Colt Government or Gold Cup. It made sure the slide went back and shot to sights set for factory hardball.
In that era, happiness was a load that matched your already zeroed sights to avoid re-doing them.
My Remington R1 (plain gun) is so much fun it ate all my Glock 21 ammo. No Unique on hand. Bullseye extra from being tired of reloading 9mm.

Same zero. One hole groups haven’t happened for a while.
More than you asked, but some basis for the information added.
I think the modern Alliant Powder is what used to be the Hercules Powder company. Some powders are the same, but some like 2400 are very different. I have used Bullseye for revolver and pistol loads for a long time.
The Alliant Bullseye site only gives useless data for the stupid Speer plated lead bullets which are neither FMJ or plain lead.
The 4.8 grains Bullseye fits into, Sinister, the poster above’s, Match 4.7 versus USGI 5.0 info.
