I started reloading right around the time of the sand hook shooting, and pretty soon after titegroup was the only powder I could find. I was given warnings about using titegroup as a new reloader as the pressure can spike quickly as you start working up a ladder test, and carries more possibly of double charging than bulkier powders. However, I found it to work great for 45acp, 380, 9mm and 38. Its not a powder that's going to give top velocities, but does make nice, soft shooting, accurate loads. But 357 is not where it shines. Right now Alliant powders are hard to find, but if you can get some 2400, Power Pistol, or Unique, those will get you better velocities out of 357. Hodgdon powders are a little easier to come by, so H110/W296 (same powder, different labels) is good for full house magnum loads, CFE-P would work for lighter loads, that's going to be the the extent of my personal experience. Accurate #9, Lil' Gun, Ramshot Enforcer, anything it that range of burn rate should get you a little more oomph out of the 357 cartridge
