Sometimes they don't break but most of the time they do
These are great paintballs with this stock barrel. I was shooting 3 or 4 shots at a time and I never broke one ball in my barrel. For what you pay for the paintballs it's a good deal $30 for 2000. Some of the paintballs didn't break, you need to get a good body hit for them to break. They only come in one color which is kinda sucks.
Worth a try for the money. I don't know how they will react with other barrels.
