Pcp tuning advice

[MddogHutty]

I have cronyed my rifle it runs around 556fps so the power setting is fine max I get from it is 11.89 for and that's perfect. Don't forget when you buy a rifle in the UK the hammer springs have already been chopped, so you cannot get that extra power out of them unless you screw the hammer adjuster screw all the way in. Even then you can only get about 590 our guys make sure you cannot over power them. I bought the rifle brand new and bought a huma reg and fitted that is why I want to learn to do the fine tuning to get everything from the rifle and reg.

That is also using JSB Exact Jumbo Heavies 18.13g 11.89fps, so if I used a lighter pellet say JSB Exact Jumbo 15.89g the power would be around 11.29fps so I'm perfectly legal just want to get it set so I'm using the reg and rifle has intended.

Thx for the detailed analysis I had already polished the hammer but I will do the other internals has well. I suppose the ballance between the reg and rifle is just writing down all the crony readings and just fine adjustments till you hit the sweat spot then thx again for the advice and I'll get on to it ASAP.
