Well I shot the FPB and loved it. I also have to say that the BH209 and the FPB are a match. I started with 85 grs. and got a group of about 2 & 1/2" @ 50 yds. When I went to the max of 100 grs. the group size dropped to less then 1".
I was very pleased. The only problem I can see is a follow up shot. It is very hard to line up the bullet when loading it in my Knight Vision. There is no resess in the barrel on the rifling. Once it is started, it runs down the barrel very smoothly.
As much as I hate to say it, I am falling in love with this damned BH209. I shot over 25 bullets yesterday at the range without ever running a patch down the barrel. I never had one problem with loading my gun. I still hate the price though.
