Wash no lube?

I understand and have a ritual with my br. Rifles, “which have excellent barrels to begin with” what I’m referring to is my 100m and hunting guns that shoot at much higher velocity’s, And just so everyone knows I’ve never cleaned or lubed pellets for 25m Br. (Hence the question in the first place) Only inspected for deformities etc. all I wanted was some input from shooters that use these techniques and their results!
 
I have and do both. I have one rifle that I wash and lube pellets for, because it actually does seem to group more consistently. Another rifle that I shoot very often, I don't lube the pellets at all because it groups excellent with out it. But, every new tin I get, the first thing I do is wash them all. There is always debris/particles in the bowl after a wash.
 
Sure, first the production engineer said only lube was applied at press to reduce wear in die’s/molds and help pellets release from die also this lube was removed after that stage by the quality inspectors this was reiterated by the plant manager/part owner that no special lube or magic pixy dust was added after production! A lot of small details can be taken away from this tour! One thing there is enormous amount human interaction in jsb’s process! “SURE IS WORKING FOR THEM and US”
