That is paint match. If you put say 5 balls through a barrel and 3 - 4 can be blown out without turning you purple then it is considered a match. Over boring is alot easier to do so if you are trying to pick a side start with overboring.. its likely your stock barrel will do this. If you underbore you have to do it right and be slightly tighter than a match, too much of an under bore can hurt and even lead to more breaks... meaning it would be wise to get a decent kit.
Also one thing that I have noticed personally is that underboring tends to be more "picky" and requires you to use FRESH high grade paint. Since I shoot a Karnivor all I can do is underbore and I have noticed my PM7 (.690) handles rec paint MUCH better... luckily I found a way to get my hands on some Nelson and I shoot a very quality ball every time I play for an unbeatable price. Running good paint through both guns gives equal results in accuracy as far as I can see. But again, try overboring first..
best of luck
