Take this with a grain of salt as this is all off hand shooting and I have good and bad days at the range, but with 6.0 grains and the cast 158 bullets, I was having trouble hitting a 2/3 size IPSC target at 100 yards (12" wide, 16" tall, 4"x4" head). With 6.5 grains, I could hit it more often than not. I don't think I tried going out to 100 yards with the 7.5 grain / JSP load.I found the load very accurate out of my blackhawk at 9.6 and a 125 grain jsp. Surprising accuracy in fact. It's a stout load and the muzzle blast is definitely there. I find it an economical load too compared to stuffing 22 grains of h110 into every case.
Very impressed with Unique so far.
