I have been doing a lot of 3.5" and 5" 9mm testing lately.

With a 115gr ball plated at a oal of 1.12"........
Bullseye to w231 powders get from 1102 up to 1139 in the 3.5"
Unique powder with its slow burn, will turn an impressive 1263fps.

The faster powders drop off with a heavier bullet in the 3.5".
I loaded a 124gr ball plated at the oal of 1.14" and tried again.
Bullseye to w231 came in with 1060 to 1071 while Unique did 1173fps.

If you want to switch from the flake power and go with the "Ball" type......
CFE Pistol gets higher fps than w231 and if you need more, go to BE-86.

With the 5" the faster powders with a 115gr ball just get to 1200fps while
BE86 hits 1300 and Unique bangs out 1350fps.

Too bad the new IMR powders dropped off the Blue Dot powder.....
In my little 3.5" the fps from Unique were embarrassing compared to what I got from BD.

Sure would be nice if they have a little flash retardant and a
better burn at the low fps range.
Later.
