Since Hodgdon lists a range of 5.0gr to 6.0gr Longshot under a 115gr LRN bullet if it were me I would start a little higher than 5.0gr. (but that's just a personal choice) I usually don't like using Longshot with lead bullets but others tell me they are fine with it. I usually use HS-6 with lead bullets in the 9mm and .38 Special +P.
