Were you using heavier BBs by accident? (Has happened to me
 )If it was shooting at the correct fps with the regular bolt, it might be something with the cylinder/flute valve.

Your hop-up rubber was probably close to give-in.
Take it appart and check carefully for cracks and wear on the inner edge. And shooting 380 on .25, your hop-up was probably quite high. Drop that down a bit.

Well you said it's shooting 290-300 on 0.20's. Is that not good enough?

Mine was shooting close to 300 with .20 on propane, with the low power bolt.
And around 380 with .20 on propane again, with the "normal" bolt. The only difference (I swaped parts to confirm) is the rocket valve in it. Low power uses a cylinder and high power used a flute/rocket valve

260 with .2g using the low power. I'm worried more about damage then fps, I'm not out to hurt people

I was thinking low on gas but the ns2 doesn't really fluctuate that much does it? I'll do some test firing tonight see what the flight pattern is like on the bb

Because 260 with .25 is about right on at 300 with .20...

Seems to shoot fine, rate of fire is about the same. Maybe it's just the bolt?
