Last week I posted to this thread and promised to provide chronograh results for my new batch of Underwood ammo.
The weather was overcast, 60 degrees F, 85% relative humidity. Also the elevation of the range was ~590 feet MSL. All velocities are in FPS
The first ammo is Underwoods 95gr +P JHP fired from my Beretta 84B w/ 3.8" barrel

Overall I'm very impressed with Underwoods ammo. I just ordered their 40S&W 180gr +P and 45acp 230gr +P Gold dot loadings that I will run over the chrono when it arrives.
