Checking my notes, using a 4" S&W M-19 .357 with a 158 gr. XTP: using 16.7 gr. of H-110 & a CCI magnum primer, I get 1217 fps. Using 14.8 gr. of 2400 & a Winchester regular primer, I get 1208 fps. These are the two "go to" loads for me with these type bullets. You should get a bit better velocity with the longer barrel.
