My best luck has been 158gr lead with S&W revolvers. No luck (in accuracy) with Colt snubbies, although that is probably unusual. All three Colts shot to POA with 158gr, just weren't accurate. Most of my S&W snubbies have been accurate, and most shot to POA with 158gr. Some didn't (one or two have shot to the right or left, one shoots very low regardless of ammo - haven't bothered fixing it yet because I have enough other revolvers).
