Thanks for opening the door. I didn't want to bring it up myself although I did the last time they did an article on me.
There is also an article published in the Dec. 2006 issue of Airgun Hobby that they asked me for regarding tuning the QB-78 and like guns. Like the QB-78 tune, the Gamo and clones that has been published, it too is also available on my website as well as in our GTA library.
For those of you that have interest in reading articles about all kinds of airgun's though, Jim Giles at Crooked Barn and Ron Saul of Bryan and Associates have put together a fine magazine and if you are into magazines, please consider them. It's not cheap but an investment and a library type keeper quality printed on heavy gloss paper that will last forever. Also, back issues are available for $4.00 each.
