Just spent a butt load of time working up a load for my XD subcompact using Unique and 231. Unique really shoots the Extreme 124gr plated well at 3.8gr (912fps) and 4.1gr (1102fps) out of a 2" barrell at 25 yds in 87degree temps at 4800' elevation. both groups shot 1/2'! My gun also like the 231, but Unique was turning better results.
