Because of my good experiences with Staball 6.5 I started using Staball Match in .223 and 6mm ARC, and have been quite happy with the groups, velocities are good, but not as high as LVR. The testing that's out there seems to show that Staball Match has very good temp stability, especially for a ball powder. I have Staball HD in the lineup next to try in my 7PRC, hopefully it does as well as the other two.
