SapperLohr get a box or two of TC Maxi-Balls and run them through the barrel,mine did the same thing it has some burrs in the barrel also and the sabots arnt hard enought to smooth them out. And check the screws that hold the receiver down, front one first snug then back one then make them tight {and make shure the barrel is centered in the receiver}but not overly tight the composet stocks a bit soft.for what it is worth my $.02 Nim
