I'm interested in some good answers as well--I botched these on the gun I just did, and ended up drilling them out and bedding them to get a good fit. No one will ever know but me, but it bugged me.
Some one here (Bill Schodlatz??) told me over the phone about a method they use that made sense but it was so fast I didn't catch much of it...but he just posted it so I'll shut up and listen
