evilstoat Posted February 12, 2009 Report Share Posted February 12, 2009 (edited) did you make sure you set the pellet grain right on the chrono ? You probably have, but it's worth checking before you get all upset...easy mistake to make...and it will lie for every gun you check if the grain isn't set right.

noluv6 Posted February 13, 2009 Report Share Posted February 13, 2009 9ft Is not to bad. I prefer 10 to be honest for extra shot's and consistency. Try packing the rear hammer spring. If you have done that with no luck get lighter pellet's,If no improvement you have a leak In the transfer port department or your pellet probe is not blocking the air in the barrell.

fo5ter Posted February 19, 2009 Report Share Posted February 19, 2009 try by first removing the stock and giving the whole gun a good clean. if the s300 series is the same as the Shamal i have the adjuster is at the back of the gun below the bolt hidden by the stock and is an allen screw. beware though that adjusting the screw is not logorithmic and turning it all the way will not get you better results! also you could end up in a bit of legal trouble. if you darent DIY or get no good result take it to a gunsmith - it shouldnt cost much if thats all it it Quote Link to comment Share on other sites More sharing options...
