I'd stick with moly.

red lithium grease is used to stop the twang by blathering it on the spring

Great thread and many thanks to all for the great tips and advice.

I have spoken at some length with Tony Leach about the best lubricants and he recommends a tiny amount of silicon oil+STP blue+WS2 for the inside of the compression tube of HW77s/TX200's and other sliding compression tube airguns.

For standard spring guns a smidge of STP blue+WS2 is good for lubricating the piston seal in the compression chamber.

For metal to metal a light coat of high moly paste(50% plus)/light grease is a highly recommended option.

Tony Leach makes a very good point of advising against super thick greases where tolerances are close(such as the inside of the spring guide) as the grease may grab and cause inconsistent/low velocities.

Well supported springs do not need masses of heavy grease.
