I got some suspension and every time I load a dart and try to push it ..... It gets clogged and only half of CC goes in..... I have tried 22gauge, 21 gauge but no good..... Also I get one he'll of a lump after I get the half of CC in there....... Any clues or any help with my problem..... I know suspension can be dirty stuff but not this bad...... I've used it in past and never had these troubles...... Help a brother out if u can.....thanks in advance!'
