So here's the first trip to the range: 170 rds of WWB 115 gr FMJ and 50 rds of Federal Hydra-Shock JHP. Not a hiccup with any of them! The first target was the first few magazines from 10 yds, the second target is 17 rds from 15 yds. The third target is the 50 rds of JHP from 10 yds. Needless to say, I'm pretty happy with the gun!
