Many shooters like yourself report benefits to using Moly and WS2 and still continue to use it to this day. I think the study I gave the link to is looking at overall net friction in a closed system so it may not be the best data to reference. If they reduced copper fouling for you then wouldn't that technically translate to reduced friction on the bullet jacket? May be or may not.
There definitely seems to be benefit to coated bullets however the coatings may not behave exactly how we hypothesize they would under the extreme heat and pressure of a rifle barrel during firing so it may lead to an increase in net friction.
I could see that transpiring for sure. The study they did and the data they collected is much more in depth than any testing I have done, which has been very high level and unofficial in recording lol. The bullet shoots nice, my barrel seems to stay clean longer so I’m my mind, it’s working hahaha. Not very scientific at all lol
Agreed. We don't know all the details of the study and the methods they used. The fact that all bullet coatings reduce velocity points to the fact that they do indeed reduce friction even if to a small degree. Many shooters seem to still be using Moly with good results even though it is considered the least desirable type of bullet coating. I want to start coating bullets and feel I will start with HBN and may experiment with WS2 as well.
