hello everyone!
I don't have a chronograph and I'd like to set the velocity adjustment screw on my spyder shutter to shoot @ 300 fps or below.
Does anyone here know the settings? (how many turns out from the complete close position)
Thanks!

it's different for every marker. the only way to know is to chronograph it. This is the same with evrey single paintball marker out there.

You can buy small handheld chronographs on most any paintball website for under $100 usually(if memory serves me correctly)

Your air source is also critical to setting velocity. HPA (High Pressure Air) also know as Nitro(gen) gives you a very constant velocity (fps, feet per second). CO2 on the other hand can be very inconsistant, depending on the ambient air temperature, and can give you lots of spikes. An Expansion chamber can help reduce the spikes. Hope this helps.
