what does it generally mean when my bolt is rather stiff when I try and pull it back to cock the gun. It seems to get progressively worse as I use the gun more, I had Julian service the gun 500 pellets ago and it was smooth as anything but now is is very stiff and also seems harder to push forward.

note. i have opened the gun since Julian replaced the seals and other things so i am in no way saying the problem was caused by Julian , just saying like

Are we talking about an s410 here?

Yes we are, probably should have mentioned that haha

when you opened it to remove the washer behind the hammer you didn't aline the breech and valve housing , loosen the screws again , line everything up again and retighten the screws , sorted .if its not sorted redo the above .

apply some grease/oil to the bolt and cycle the action several times

not too much just a dab

wipe it on then wipe it off , too much will clog it up and make it stiff again .

I have always used good quality gun oil on most moving parts in a rifle. Grease has a nasty habit of collecting dust and grit and then not letting it go. High load points I will used moli grease but in as small an amount as I can get away with, a sliding bolt isn't high load in its channel but the cocking link can be so on that I used a little grease.
