Just received my Uragan2 from Talon Tunes in .177 cal. One hole groups at 25 yards is the norm. Fx 10.3 shoot best. It also shoots jsb howlers very well. Extremely pleased with this rifle.
Have you ever shoot a v1 Uragan? A lot of people are wondering how the balanced valve effects the cocking and the trigger feel. Also how is the hammer slap in your ear? My v1 .177 Compact hammer wasn't too loud, but definitely noticeable.
