I've seen some posts where people are trying to shoot test, deca, etc with 27 or 29g needles.....this is damn near impossible with a 3cc syringe, but if you use a 1cc barrell its much easier.....the physics and pneumatics of the barrell and plunger make a big difference here. For example people say NO WAY you can push through a 27 or 29 when they have tried a 25 and had problems, but most likely they were using a 3cc syringe.
with a 3cc pin you have a bigger barrell and wider plunger and takes more force to force it though there, if you backfill and insulin pin for instance the pressure in that barrell is MUCH greater when you press on the plunger....that being said shooting oils with a 1cc barrell and a 27g pin is VERY feasible
