So what is the most efficient pump? My Empire Trracer was set at 271fps with a fresh 12g and gets 20 faily consistant good shots and 50 total (above 200fps). My Unibody Phantom get's around 40 total and my Sterlings around 35 and the Tippmann SL68II only gets around 25. Of course, they could all be tuned. What do you get? Does anybody even use 12g's anymore lol?
