Having just stripped and cleaned by new/old .177 HW77K, (smaller piston model) I have decided I need a new spring. The current one, round section) has a good 3 inches protruding when the block is removed and it's not under pressure, and looks a tad wonky. I also think it might be worth replacing the spring guide while I'm at it. The piston and breech seals look to be in good order.
So, recommendations please.
BUT!
I don't want to shoot deer with it a 200 yards, or smash a pellet through a tree trunk. I want it under 12 ft/lb. Neither do I want a custom spring, rolled around the nipples of a fair Rhinemaiden and coated with Odin's snot. I just want a quality spring that hasn't been ground off at the end to bring the power down.
