went out today and shot the .30 cal, i couldn't hold down any type of groups @45yards. when i try'd to switch back to the .25 barrel i couldn't get the 30 cal barrel out of the gun. i had to use so much force i think i bent the shroud, it's very tight now to extend and retract it. and the set screw for the pellet probe is coming apart or the aluminum thread is coming out of the hole. i guess i should have stuck with the bobcat. i think this thing is going to be up for sale. to much money for to many problems.
