Since you mentioned your FWB. Here is a pic of my FWB300S which I've set it up for 25m benchrest.I really like 10 meter rifle. The old Feinwerkenbau with Anshultz sights is still amazing. Mine is 50 years old and needs seals about every 8-10 years. Once you get past the toy store pellet rifles, they start to get really good, and really expensive. Get a good air rifle in your hands and you soon realize the rifle is better than you can ever be.
have fun!
