That post on the large caliber airguns got me to thinking about something. A while back I was intriuged with building my own PCP Air Rifle, probably a bigger bore piece. On researching the net for information on the subject I learned that there was a book published in the U.K. on how to build a pre-charged airgun. It was supposedly pretty complete and a very good reference. You wouldn't by chance be able to locate a copy of that book for me would you??? I'll look around and find the title and author for you if you wouldn't mind trying to locate one for me. Over hear they are pretty impossible to get ahold of.
Let me know if that's something you might be able to do.
Thanks, Matt
"The Modern Pneumatic Airgun" by H.M. Buckley is the book title and author
