Hello Lawrie. I've done some boring and sleeving lately. I followed advice I received from here on the Barn. I leave about 1/8" at the bottom, which might look a little less at the actual bore because there is a small chamfer on the bottom of the bore.
I've shown the process in some of my videos.

For instance you can see the step in this video:

There are many others too.

If you sleeve to a bore smaller than the existing bore you want it as low as possible. 2-3mm is fine. It just needs to be strong enough to resist the slam of the liner. If they go in right with a heat/freeze process they can really slam in there.

Mart.
