h&n .218 and .217 21g slugs. carbon sleeve vs o rings lubed slugs with furniture polish. on the .218 21g with the orings and lubed slugs the pin probe jammed one of the slugs.
Speak friend, how are you? So there's not much difference in using the sleeve? I noticed that without the sleeve it was even better. What did you think? Hug from Brazil.
Some of the slugs were polished for the testing, some were straight out of the tin. I didn't polish the barrel. The barrel was the standard 600mm stx pellet liner (not the superior)
