Reply To: fx400 accuracy
We might need a bit more info if anyone is going to be able to help, is it .177 or .22, did you buy it new or second hand, if its second hand perhaps the previous owner has adjusted the hammer spring tension? Is it the power adjust model or an earlier model?
A regulator will give you more consistent velocity across your shot string but finding the right pellet for your particular rifle will help with the accuracy, what pellets are you using, are they of a suitable headsize for your barrel? Do you have a chronograph or access to one as you really need to know the velocity. Yeah, I know a lot of questions but I was new to airguns a few years ago and had to go through all this also and still learning,lol.
I have a Royale 400.177 un-regulated and I get approximately 120 shots from 220bar down to 100bar on power level 3 with hardly any shift in POI at 25 metres using H&N Baracuda Match pellets and my Royale 500 with a regulator installed will do 65 shots ( JSB Kings ) at an average 930fps before it falls off the reg. at 140bar.
Edit; I see its a .22cal, you answered before I could.
