That's what it feels like Jon but I'm sure the piston has a black plastic grease tube that the spring sits in, so the cocking shoe shouldn't touch the spring in theory.

Far too many rifles to list now, all mainly British but the odd pesky foreigner has snuck in
Sounds like the piston sleeve is too tight.
If you're guides are good, no need for a sleeve .
Need for tightness to kill all vibration varies.
Setups with a lot of preload, like you ususally find in the Supersport/Lightning often need tighter guides than other guns,
as the preload opens the spring ID when the gun is assembled.
As you say, tight guides often gets most of the lubricant scraped off.
If there is no visible heavy wear marks on your spring/guide, I'd leave it alone, or perhaps smear some high content moly grease between the coils.
Too many airguns!
