Can't really say much that hasn't already been said regarding the new Vulcan. I purchased the 25 with an Aeon 6-24 scope and simply love it. Shooting consistently 928 fps with JSB Kings and one ragged hole at 35 yards for me using only shooting sticks for a rest from a chair. Action smooth, able to easy maintain sight picture between shots cocking with left hand and trigger right.
I don't have much experience to compare it to other than my only other Bullpup...Evanix Max ML 22.

The Vulcan feels almost half the poundage of the Evanix and more like a pistol than a rifle. The sound is about equal for the two with a fairly loud "ping" but the Evanix is a 22 and Vulcan a 25 which says a lot. I am fine on my 5 acres but wouldn't recommend it in a suburban development. The Vulcan is exactly what I was looking for in a high powered compact varmint rifle that would be easy to transport and shoot from an ATV. My only complaint so far is the scope to barrel distance which is inherent with bullpups. Mine is 2-5/8 inches and will just require thinking through the pellet trajectory before pulling the trigger.
