I have a Spyder TL+ and i want to make sure the velocity is correct. I dont have any place avalible for me to go or a machine that test velocity. So if you have the same gun as me or a similar gun, How many turns (from the closed position) do i need to turn the power adjuster thing to get about 280 FPS.
Even if it is the same make and model, each gun has variances with each other. You can't set the fps because someone else's velocity adjuster is turned a certain amount of times. Even with it turned all the way out, it could still be shooting hot.

There are way too many factors to just turn the knob a few times. If your running co2 the temp effects velocity. Another factor is the paint to barrel match. Since you can't go to a field to chrono your marker, BUY ONE. The handheld RadarChron is $79.00, or the Brass Eagle chrono thing is a valible at WalMart for about $40.00. This is a very important peice of safety gear that you must have, since I assume you play renagade ball. Good luck and be safe.
