Does anyone know what velocities some of the factory defensive 357 ammo run? I've had good results with 125gr Zero jacketed bullets and Winchester 231 for low/mid range loads, between 800 and 950ft/s (38 and 357). I just ordered 1k Berry's plated 158 grainers, and will be working up a high-end load, for practicing with 4" revolvers. Win231 seems to tap out at just over 1100ft/s. Probably will go with a different powder. Wanted to get an idea what full power load means. I saw some data with Win296, and max velocity is almost 1500ft/s. Probably have to fill the casing right up to the rim to get that... Any information will be appreciated. Will save me $$$ from making the measurements myself. Wanna kill these ads? We can help!
