I think you should save yourself a huge pain in the ass and get you some 18 guage to draw with. You don't have to constantly push the air bubbles out or beg the shit to fill the syringe. I shoot with a 22 guage, and draw with an 18. Shooting with a 25 is also a pain in the ass, having to push the plunger so hard to get the oil through that tiny ass 25 guage hole. You gonna run with the big dawgs, man up and get you some big boy needles bro. You will be happy you did.
