Air Arms How much lube?

[Michigander]

This is a question that has no simple answer, but I thought I would relay my experience with my TX200HC in case it might be of help. The story starts last year with a tweak to the rifle's spring and a relube. After thoroughly wiping the bore, I lubed the OD of seal, piston and spring with a bare minimum of Vortek orange grease. Just a film really, with no buildup. This seemed to work for a while, but then I started seeing vertical spreads to my groups.

So I tore the rifle down again, and this time applied a thin layer of the same Vortek grease to piston and spring, perhaps 1/64"-1/32". I hoped this might be enough to get transfer to the cylinder wall and provide more reliable lubrication. So far results are good, tight groups and no detectable smoking or other signs of seal bypass. Here is today's target showing good consistency except for that last group that I will chalk up to an error in NPA, which springers seem especially sensitive to.

Don’t be afraid to lube the underlevers. That being said the more you use the more hydraulic loock you will get creating a slowing things down process . ,but a much quieter dead thump. Velocity is over rated than accuracy.

I use a a calcium sulfate base lube that is water insoluble as it isn’t affected as much by temperature.

The main thing is use none ,none on the piston seal at least 1 inch back

Just a thin film of molylube to ease insertion. The black Vortek seals are self lubricating. If you see white smoke out the barrel ,you used to much. Shoot a few heavy pellets to try and burn it out.. if your lucky you won’t have to bust it back down.
