Do you guys have any recommendations for forum(s) related to air rifles, etc?

Steve,

If you're looking for high-tech general airgun information as pertains to ISSF-style shooting, you might try:

www.targettalk.org

Be advised that the folks on there are pretty narrowly focused.

OTOH, if you're looking for airgun info that's within the silhouette community's area of interest, you're already here! lol
Whatcha trying to find?
