I replace the springs in Howa HACT triggers for 2lb ones as a matter of course and it works extremely well. Get them from a bloke in Aus.
They are available for the older single screw triggers. I’d be doing that before cutting springs as once its cut, its cut and I know of one rifle (older Howa) were the owner didn’t want to spend $15 and ballsed it up and ended up spending $15 anyway. There are some other polishing tricks you can do.
