I was wondering if the Chrono was reading low (LabRadar - definitely on the right settings). But then I ran the new 357 Mag 180 grain load from Lost River and got some crazy high numbers. ~1625 FPS out of a 6” GP100 and ~1700 from a 7.5” Redhawk.
My biggest uncertainty with the loading was definitely the crimping. I’m using Hornady dies, and the instructions are a little vague and subjective as far as crimping goes.
Hodgdon data shows Lil’Gun start load at 18grs @ 1140fps for Ruger loads
