The original reason for purchase was because I was using twin 98 gatlins. I needed a cheap paint that wouldn't break in the barrels. I read a few different reviews and these seemed to be the best ones for what I needed.
True to the other people reviews I only busted one in the 4 cases I went through while hammer. This did come at a price however. I would say at least 1 in 50 was deformed so that normal flight was impossible. Also firing at 270 FPS at least 1 in 3 didn't break. I had more people surrender without being marked for fear of getting hit by another "flying marble".
I sold the hammer around August and begin using my WG-65 more regularly. This is where the monster ball really failed me. With the above problems I have listed the fact that I wasn't using 700 rds a game begin to take effect. The inconsistent accuracy and lack of breakage was not nearly as big a deal when you were only supposed to lay down a tremendous amount of firepower and chop through brush to get to the opponent. As a front runner I needed the balls to break and to fly true. This they did not.
All in all I do recommend Monster Balls to any player who needs to lay down a lot of paint. I paid $30 a case at Wally World and they will not break in a flatline barrel or any barrel for that matter. On the downside the hardly break on anything at all. But if you play anything that requires less than a case a day I strongly reccommend looking into a little more expensive paint. It will be worth the price.
I get 2,000 Monster balls at wally world for 20$ but they never break. I used to get freedom balls and they were very inacurate I would recomend dust paintballs because they are accurate and they break on impact.
