So I went to Wal Mart to buy some paint, because I really wanted to test the Z2 and my Axe. First off the Wal Mart paintballs were terrible as they always are. As I go outside, my gun is set to 12.5 psp, has boss XSV bolt with long spring, and I was shooting and had a few paint breaks, so I go to check if it was the z2 or the Axe. And surprisingly to me, it wasn't the Z2. Now I didn't have a chronograph and didn't even check my gauge, so I'm not disappointed that the Axe broke paint, the paint was awful, and I'm proud that it shot as much as it did.
But you were right, the Z2 is fine.
Thank you for the help, I will continue to come here before I go anywhere else.
