Thank you for the pointers, Dusty. I'll give it a try then strip it and oil it as you described.
Regarding tanks, I have an 88/4500 Empire tank that I use. The steel tank came with the gun and is a 48/3000 if I'm not mistaken. It feels nice on the mag though. Maybe I'll get a 45/4500 or stubby 70 when I have the funds. For now, if hydro is good, I'll use it!
