Well actually I never really poo-pooed them but stuck to my guns and laboriously shimmed and re-shimmed and re-shimmed to get good tube to bore alignment.
Then I bought fdshusters 36x Leupold (Thanks Franks) which included the Burris rings and zero inserts. I ordered a set of .005",.010", and .020" and received them a couple of days later.
It took about 20 minutes to have a perfect alignment with a centered everything. Boy let me tell you I'm going to start being more open to new ideas.
These things are GREAT! tom
