Ceramics and stainless.
Very, very, round. Predictable bore size from batch to batch.
Not exatcly cheap.
Putting 1000 of these thru my 16" J&J ceramic was very impressive. At 100 feet, 11"x10" target, 20/20 breaks on target. The best result i've had yet. These are some of my favorite balls to use. Its very interesting the response you get from nooby players when you show up with good paint. It seems to have an intimidation factor all its own.
Extremely round, not dimpled. Good paint.
My J&J is a medium-wide bore, so it shoots most paint fairly well.
Great paintballs. Great option. I'd take em to a tourny. I reccomend them, by all means.
