I,ve tried several different powders in looking for consistant mild loads
for my 4" 29-2 with a cast 250 gr SWC. I quickly gave up on Unique
and I believe 231 is great for loads a little hotter, at mid-range level.
In my gun with a 250 gr cast SWC 6.0 grs Red Dot = 834 fps, 6.2 grs
Bullseye = 829 fps,and 7.1 grs Titegroup = 954 fps. The Bullseye load
was more accurate in my gun.
