I always give my pellets a rinse when I buy new tins (sometimes depending on which brand) but I did buy some lube and after a rinse and a spray with the lube, I was still surprised by what gunk came off from the pellets/tin- if you could only imagine that in your rifling?
Although I purchased it for the care of my rifle, I don't think it has a great amount of influence on accuracy. UNLESS you're comparing a barrel that has lacked TLC with pellets straight out of the tin, as compared to a well maintained barrel and pellets rinsed and treated, I personally can't see a lot of difference.
