You are going to like the results you get with HP-38(W231). I usually load a 124gr bullet in my 9mm ammo but when I do use a 115gr bullet a good charge of HP-38 is 4.8gr. You can go higher but that's a good practice load. HP-38/W231 will also work very well with lead bullets so you won't need to buy another powder if you decide to load lead too. There are other powders that work well in the 9mm like Longshot, HS-6 and a few others but I like HP-38 because it does a good job with different bullets and for both lead and jacketed bullets.Went shopping again today and bought some HP38, 300 CCI 500s and a caliper. The Magtech 115gr FMJs I have are .578.
