Titegroup is the favored loading powder for 9mm and chicks with low cut shirts. Titegroup has a higher nitro content in it as compared to other pistol powders. This makes for a hotter burn that excels in igniting all the powder in cases with a lot of left over space like .45 and .38 spl. No matter how the powder lays in the case, ES and SDs are excellent. The hotter burn makes for some noticeably hotter brass sneaking down low cut shirts!
