I should probably clarify what gun I am going to be using it in. I currently have a Ruger sp101 with the 2.25" barrel. I know short barrels reduce velocity, although I would still want a heavier buller for better penetration right?
The shorter barrel magnum will still give you 400-500 more FPS than the same weight bullet in a 38 special loading. I would and do stick with 125's and heavier, but I am just an old street cop.
