I just got 2 new mags from ehobby that can't seem to get off more then 10 shots. The mags should fire 15, but I only really get about half that. I lubed the gun, I put 2 drop throught the valve into each mag. I haven't pressed the big button, only emptied through firing. I started by filling for 3 seconds with propane, but that only gave me about 4 shots. I've tried 4 second and 5 seconds, the latter gave me 10 shots. I don't know what to do now.
