teflon coated barrels ?

Does the teflon coating on a barrel help or hinder the cooling characteristics? Anything noticable with POI due to harmonics changes?

    I don't have anything to back this up other than my own life experiences but it seems to me that since teflon is less of a heat conductor than the metal barrel it would therefore slow the cooling process.

    As for the harmonic part of your question I would guess that it could go either way. It might dampen vibration or it might not. It does have a different expansion rate then metal as it heats up but would it matter? I doubt it.

    Re: teflon coated barrels ?

    I remember three years ago having a black carbon fiber wrapped barrel. One day I left it sitting in the sun for an hour before shooting in a fun match. Its barrel became almost too hot to comfortably pick up. I don't think that dark color helps cool a barrel.

    Teflon is usually a dark color, my last one was black. I don't use teflon for a barrel any more.

    Len - What do you use now? Is there something other than teflon to coat a barrel? I like the wear of stainless but don't want the shine. Can stainless be blued?

    Most people use a vibratory sander while turning the barrel in the lathe, or just plug it and bead blast it. But, the vibratory method doesn't show scratches.

    I don''t know if you can blue it. (Any gunsmiths out there?)

    You could bead-blast it or sandpaper it. I have decided not to worry about the shine for a long range hunting too.

    Bead blasted SS when blued will turn several shades darker grey, not sure how much darker it looks on a polished SS surface though.

    I could take some pix if you're interested, blued next to non blued SS, both bead blasted?

    My Dad likes the darker finish of the blued SS.
