I've read on these forums about under and over boring instead of bore matching to get better accuracy during games. Of course non of these methods will work when dodgy paint is used, but all the information i have found has always just talked generally about going bigger or smaller on the bore size without being specific on how big or how small to go. So the question is I have 3 markers that all have an autococker threaded barrel and plenty of different sized barrels and an Evil pipe kit. The markers are an Ego 8, a MacDev Cyborg and my trusty old Eblade autococker just incase this effects what bore pipe to use. Assuming that the paint is of a good quality and of a middle size, should I go one or two sizes larger or smaller depending if I want to try over or under boring?
