Thanks mate iv got the bolt set at one noch past 90° ( strait down . I used a little gun oil but wl give that a go. Thing sounds like a zipper every time i cycle the action

One notch towards the muzzle or the butt stock ?
Towards the muzzle is better, as when you unlock the bolt, your pulling straight back.
Take the bolt out and lightly lube the bolt head ball bearings and make sure the bolt release channel is lubed too.
It needs to be broken in and once you get used to it, your turn bolt rifles will be lonely.
