As far as data is concerned with Unique and Universal. Here is what I have for .45 Colt to compare....
Ruger BH 5 1/2" barrel
8.0g Unique, 250 RNFP, CCI-300, _922fps, 18 SD, 55 ES, 20 shots
9.0g Unique, 250 RNFP, CCI-300, 1021fps, 19 SD, 62 ES, 20 shots
8.0g Universal, 250 RNFP, CCI-300, _894fps, 13 SD, 44 ES, 13 shots
9.0g Universal, 250 RNFP, CCI-300, 1013fps, 17 SD, 58 ES, 36 shots
I can't any difference accuracy wise between the two and feel the same when fired. Can't say whether one is 'cleaner' than the other. Seem the same to me...
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
