It freezes with the thick fill and dsn't always break with thick shell.
With my Boomstick this paint has been very excellent to me since I couldn't find the jt maxim paintballs anymore. Every time I use this paint it shoots good out of my boomstick. Since I started buying these I have went through almost 5,000 paintballs and could count the number of them I hav broke on one hand. But If you live in a cold place these may not be the best for you because my'n started to freeze in 30-40 degree weather. Also because they have such a thick shell not all of my'n broke on my opponent just left a nasty welt. But this came in handy when I had to break through a bunch of grass to get to my best friend : ). I would recommend this paint to anyone with a boomstick. It is great stuff for my barrel. I could shoot a nat off of a fly's a** with this paint. Plus it's cheap.
Anybody with a boomstick must buy it it has done excellent for me and hopefully it will for you too.
