What is your preferred lubrication?
I recently acquired a texan .257 and while the AVS slugs I ordered for it that shoot incredibly well are clean I still decided to run them through my ultrasonic cleaner and then lube them with a coating of ballistol.
With that said I shot 130 slugs I cleaned and lubed myself before diminished accuracy occured :O
The next day, I shot straight out of the box AVS , 70 shots before I noticed the accuracy diminish.
So it seems there is a benefit here, I have been cleaning and lubing my 44.75 pellets I shoot from my paradigm and I barely have to clean it.
