I was just sitting here reading the loading data in the copy of "Complete Guide to Handloading" by Phillip B. Sharp, that I got at a gun show last year.
It's copyrighted 1937,1941,1949,1952,and 1953.

There is quite a bit of loading data here for the .45 Colt. But the Unique section was what got my attention.
The data listed in this old book is almost identicle to the data listed in the new Alliant and other current loading manuals.
Talk about consistancy.

Here is the Unique data:

BULLET...............POWDER...............BALISTICS
...WT...TYPE.....KIND,.CHARGE....5.5"TB.VEL.PRESSURE

250...Fact.Lead..Unique,..8.0..........850
.."......."......".........".......9.0..........930..............11,600
.."......."......"........."......10.0........1030..............15,000

255.....Ideal....Unique,....9.0..........940..............11,500
..".........."..........."........10.4........1045..............15,000

255...Fact.Lead..Unique,..6.0..........680
.."......."......".........".......7.0..........780................9,000
.."......."......".........".......8.9..........960..............15,000

258....Bond.F....Unique....8.0..........800
..".........."............."........9.0..........890..............11,700
..".........."............."......10.3..........990..............15,000

Notice how the velocitys and pressures are so close to what our current loading manuals are telling us.

I think if I had to choose one pistol powder for my handguns I'd choose Unique.
