I actually like my nocks to snap on, I wouldn't think of altering them to make them looser. When they start to get loose its time for new nocks, or maybe even new arrows.

How tight or loose they are isn't really the issue, its consistency that is the issue if you are worried about utmost accuracy. This is why some of the magnetic nock systems are supposed to be better.

I bought some Luminocks a couple of years ago, and they fit so tight on my string, that I took some 80 grit sand paper, and sanded the inside of the nocks down, so they fit perfect. I have never had a problem from doing this.

I do it most times. Ideally I would not, but have learned getting a perfect fit between served string and knock is bleeding hard to do otherwise, and I like to get it just right - so a good thump doesnt pop it off the string, but loose enough so I loose a minimum of fps by it sticking to the string at release. Have not had any problems in eight or so years, usually a few passes of a nail file does the trick.

If they're a little tight I'll fold up some finesand paper so I have to force it into the nock.I'll drag it through them a couple times, or however many it takes to get them all the same. Yes, sometimes I've gotten overzelous and shaved off a little too much so I plop on another nock and do it again.

Exactly!! I'd never file mine either.

I have when needed.

no , never even crossed my mine to file the nock. mine work fine the way they are

Nope!!
