Like I said the 6450 is as smooth a shooter as they get.
Smooth yes, but you said:
there just is no flip, dip or movement at all compared to a 223.
The same man shooting one of each showed that the 9mm version does in fact move as much as the .223. Do we need to see if the same man has demo'd a .22LR variant so we can see if it moves as much as that 9mm?
