There is a lot of nonsense discussed reg Silicone oil.
The original legend that it has disastrous consequences in airguns, probably came from in-pure grades, and uneducated use. Then we have silicanes, silicones and impure types.
Maybe 30 types and grades…
A decent Silicone gun oil like RWS chamber lube would have been pure Silicone and that is where to start.
Now, Silicone (even the correct stuff) may well cause a touch of galling if used on the breech lock up face.
This is the high pressure relocation of 2 steel surfaces, but i have never encountered it causing an issue on sliding fit surface like a piston in a piston chamber with the typical 0.2mm. clearance but because of all the jumping on the bandwagon on the web, you are being put off using a fantastic none drying lube for the seal, providing remarkable consistency which has never been bettered for that aspect by all these modern Molys etc….misinformed, or mis- user across the web ….causing the issues.
I once ran some Abbey 35 Silicone gun oil in a bearing with a rotating shaft, on a lathe all day at high speed without noticing a hint of galling and the silicone still wet and in place.
I have used it for eons on springer seals with never a single issue ..
