I don't do it..never have, never will. To me it just feels like an added choir. If you buy good quality pellets 9/10 they're pretty clean an very rarely need binning.a boy on facebook lubed his pellets with Napier stuff, and it caused it to smoke and make a loud noise (dieseling) ..I just think its a farse to get you buying . No one had a pcp back in the day, nor a range finder, or a mildot scope..now there's electric firing airguns. That's it next year I'm getting a Springer again lol I'm rambling on here like I date back to the 40's lol
