Just received a new feinwerkbau fwb sport. The caliber is .177. Shooting an 8.4 jSB pellet I got a velocity of 899FPS, this yielded 15.04 foot pounds of energy. That equates to 20.39 Joules. That is a lot of power from this rifle. The reviews that I read prior to purchase were, for the most part, negative. The price was right so I gave it a shot. I am very happy that I did. The stock is beautiful, the gun is unique. I think that the basis for the negative reviews is that the gun feels much lighter. This kind of magnifies the felt mechanism of the rifle. I still did not find anything very objectionable. The accuracy is very good with open sights. I have not put a scope on it yet. I plan to shoot it quite a bit more before going for any optic. I cannot say enough positive things about this gun. I think it just got a bad rap out of the gate. This resulted in prices plummeting as it first opened at about $900. The prices went down considerably. I picked up mine for $495 ($520 with shipping). The gun also is listed as producing 14FPE which converts to 18.98 Joules. Mine clocked in at 20.39 Joules (15.04 FPE). I expect this to calm down after a while. The listed weight is 8.27 pounds. It is very well balanced and feels lighter.
In the Adam Smith version of the world.
I bought mine at the lower price. I never owned the older one. I like it a lot. Had an old school tuner guy in Texas tweak it up, it's a nice gun.
