It's on par with anything Blazer, Remington, Winchester, et al makes.
I've run their "bear loads" in 357 mag and 44 mag in lever guns and revolvers. I've run their "cowboy loads" in 44 spl and 32-20 in revolvers. All of it has been 100% reliable. All of it has been consistently accurate with consistent velocities. Top quality Starline brass that I've reloaded for seemingly forever.
