Black Bullet International...
I use them and with 4.5- 5 grains of clays universal (I don't remember which I settled on as it has been awhile since I rolled any)
Minimal leading and a little smokey but not too bad.
Price is pretty good as well and as far as accuracy goes I average less than 2" at 7 yds 3-4" @ 15, and beyond that I can keep it in the IDPA chest circle.. Hey I never claimed to be a phenomenal pistol shot, however, my handloads with a .45Acp coming out of my old Kimber were much tighter so I blame the equipment
