They are around .687 so any barrel that size. I used my .689 cp and they shot very decent.
Strengths:
They are super cheap.
Quality for the price is awesome.
Weaknesses:
A few dimples (not very many).
Review:
I ordered 8 cases of this stuff from firstcallpaintball.com. For those of you who don't know what blitz is here you go. Blitz is first and end run paint, which means it is the paint they produce when they first turn on the machines and when the shut off the machines. DXS does not actually make paint that is called blitz. You get one of there brand names just not the middle run stuff. I ended up getting blaze but you could get any one of DXS brands.
The stuff is great. You can not beat $30 and it shoots great. The only thing I saw that was a con was I pulled 2 dimpled balls out but that was it.
For the price it is a 10 for sure.
Conclusion:
If you are tight on money and need some paint you can't get better cheap paint then this stuff. Buy it!
