Would like some input on barrel polishing. Have seen some videos extolling the virtues of barrel polishing. They are claiming greater accuracy, and yet, I talk to some air gunners and they rarely even clean their barrels. Throw in sizing, sorting, cleaning, lubing, testing a plethora of pellets and lubing. Then, add installing dual transfer port, power plenum, carbon fiber barrel sleeve, the list is only limited by bank account. Are we expecting perfection out of mass produced items? Should every shot be hole in hole? Add all those things together and it leaves my ability to shoot an air rifle. I think I need to start with making myself a better shooter and not a compulsive consumer of gadgets.
