Things I liked: I also own a rather dated, yet still highly accurate FWB 300S. In comparing the two, the drulove eagle certainly holds it's own, and produces very similar scores. I didn't think i would ever say this, but i actually prefer the Drulov due to it being lighter to hold while standing and shooting at 10m. I love the idea of the 5 shot semi auto feature, and found that RWS R-10's gave the best results.
Things I would have changed: Changed the basic sight assembly for diopter sights...wow what a result. It now looks better and the groupings are more consistent.
What others should know: I'm averaging around 60 full power shots (470 fps) on one 12g co2 cartridge. As i mentioned above, the best results came from using the more expensive pellets H & N Match and RWS R-10's, but R-10's were best.
