The rifle I am thinking about lowering the fps is now shooting at 915 fps and I was thinking of lowering down to about 550 fps like a target rifle it is now very accurate like one ragged hole with iron sights at 10 m now by lowering the fps the pellet will stay in the barrel longer does this mean that it will be more hold sensitive , I don't know if this is a good idea since the rifle is so accurate all ready. it is a 177 cal. howie
