HELP!!!!!

[Scuzy 1]

Hi all,

 

A while ago i purchased a Webley Raider .22 2-shot and ive had no problems with it until today when i decided to buy a chronograph.

I set it all up and when i finally got round to testing the gun the first shot read 11.7ft/lb's with 14.5 grain powapells - Nice! NOT!

The second shot read 11.1 ! Then the third shot read 11.9 and fourth 11.5!!!

I ran out the air and refilled my gun to 200 BAR and the same happened again , it isnt going above 12ft/lb's or below 11ft/lb's its just varying to every number in between ?!?!? Ive also noticed that my shots are now grouping perfectly from side-to-side but they are grouping up and down with a varyation of 4 inches!

Is there anything i can do to correct this?

 

Any help appreciated.

 

 

Regards, Luke.

to me the power seams fine

 

remember if it not an fac gun and you don't hold an fac then its illiagle to have an air rifle above 12ftlbs anyway

 

 

now the grouping try using a more acurate pellet maybe crossman acupells or air arms fields jst mess about with few different kinds and see what kind your gun likes and dislikes

I’m a bit puzzled, you say you’ve had no problems with your gun (fine bit of kit) until today when you chronoed it, checking for power levels through a chrono would not result in poor groupings but the fluctuating power levels are a bit odd.

What make of chrono have you bought.

I have a CB-125 chrono and it works fine on my other guns, im just concerned about the power curve not how powerful it is.
