I got my RRA 458 socom upper and put it on my DMPS lower. Took it to the range with my son a few days ago while it's sunny. Fired at water bottles, milk jar, Vitamin Water bottles...etc. It was fun. When I hit the milk jar, it exploded into a cloud of mist 15 ft high. Even the guys down the range was surprised by the power of the 458 socom at 50 yards. Now, too bad I didn't record it because I had to rush to pickup my son from school. Next time, I would freeze the bottles to see what happen when hitting ice...could be fun.
