s400 pcp single shot problem

[jonesey 2]

hi all

 

was shooting with a friend with his AA s400 and was missing the pigeons etc we would usually hit by miles,

took the rifle home and couldnt zero it (not enough 'up' adjustment in scope) so tried a different scope and it shot cock on for a while from a full charge (200 bar) then pellets kept dropping at intervals and some shot dead on some low etc. tried scope mount padding to increase up adjustment but with no benefits. had the problem before with his rifle. im thinking it could be the sears/seals have gone (although i believe they were replaced last service?) due to the inconsistent pellet elevation from inconsistent air pressure being released bt not sure? [NO TEXT TALK] else ever had this problem?

any elp would be greatly appreciated

I have an S400C and have been advised not to go above 190. It could be seals as you say and the pattern of good/bad poi suggests this.

I do wonder if maybe you gun is not loading properly. The hammer may not be being held properly in the correct position.So some hammer strokes differ from others .The guns change in fill pressure should not effect the guns ability to load .It could be grit or something in the mecanisum ,or something loose or worn.
