The second link from the second post, is the guy that "wrote" the "how to" threads in Rimfire central for the buckmark. Just FYI.
The second site from the 2nd post is a little weird as far as operation, but it is the best info you can find anywhere, IMHO.
The buckmarks are a bunch of fun untill you have to detail strip them. Usually I do mine every 1000 to 1500 rounds.
Cheers!
