I don't know what to think of these paintballs.
When I opened the bag I dropped one from 90 centimetres height and it broke. Then I threw one from my second story window and it bounced.
Checked them for roundness and some are totally round while others are egg-shaped. No dimples as far as I could see.
Shooting them:
Reasonable accuracy shooting through my .689 All american back. Some early dips, but mostly straight and spot-on.
No breaks in barrel or in breech.
Broke on target every time (that I know of).
They smell horrible! The 50/50 design yellow and metal smells of... hmmm... corrugated steel or something. Wouldn't serve these paintballs as a thanksgiving dinner.
No problems with my bounce-beam eye either...
Conclusion:
A good paintball... Not good enough for the price and all the hype around RPS, but a reasonable middle-grade marking pellet.
Won't buy them again since there are better deals available out there.
