    How long can a pcp stay cocked? For example, I load a pellet into the breach and wait.. how long is too long to remain cocked without firing?

    Are you thinking along the lines of hammer spring fatigue and negatively affecting the function of it?  

    I don’t know, just guessing but, I don’t think that it would hurt to leave it like that for days and cause any problems.  Months or years may take a toll on the spring but surely not a few minutes or even hours for a normal shooting or hunting session to impose.

    I am curious about this also since I see videos where hunters cock the gun instantly after shooting their target. The next round is expected to have a slightly lower velocity since the hammer spring has been depressed for x amount of time. How much less? I’ll leave that to the ‘experience’ in this forum.

    Edguns Leshiy is cocked when folded, Ed left his .25 Leshiy shooting kings at 225mps for two whole weeks. He then took it out, unfolded it, and shot through the chrony. It shot 225 mps so no difference whatsoever. If you want to see the video go to his youtube channel “The Edgun” and check it out. Think it was called Leshiy hammer spring test or something.

    There is a huge difference in the amount of tension on a spring from a Springer Air rifle and a PCP
    While I wouldn’t leave it cocked for months or years days wouldn’t hurt it.
    My only cautionary word is that since air rifles don’t have the oversight that firearms do I would be concerned about safety of a accidental discharge.

    I leave my Huntsman classic cocked (not loaded!) for days (weeks sometime).  I need to cock it to remove the mag so it is how it remains.
    Pcp are no springers and the hammer spring shouldn’t be over stressed to be an issue.

    When finished shooting I also must cock the weapon to remove the mag but then I hold the bolt and ride it forward as I squezze the trigger decocking and letting the pressure off. 

    I dont  know the inner workings of the gun but it makes more sense to me to not have it cocked when finished shooting for the day. 

    Some auto hand guns I have, have a half cocked position with thumb luck that you can use but that is a different animal.

    That’s some good information guys. So I should not worry about loading a pellet and stalking for a few hours if need be.? I usually will fire off the pellet into the ground after about 5-10 minutes if nothing appears. 
     I can relax not and be more prepared for the shot!

It depend on the quality spring and the compression length.

Just so you know, they can be safely decocked. After you cock it and remove the magazine, pull pack the bolt all the way against the spring, squeeze the trigger, then ride the bolt forward. My back door gun, I usually take my shot at the varmint and only cock/load again when I see another one that needs his lead. On a lot of springers (for example, most break-barrels) you can do this too, but it takes a lot more muscle to ride it closed safely.

    I like to use an old trick from having a revolver, I will leave my first chamber empty on my clip, if I want to be able to safely leave a clip in then I will hold my clip on the empty chamber, lock it in and close the bolt just enough to stop the clip from rotating then as smauge said hold the handle and pull the trigger and let it down slowly.
    This way I am on and empty chamber and decocked but can do a fast “locked n cocked” without concern of double loading or moving in heavy brush or unsafe conditions with a hot weapon.
    This is a good way also to be set up for tree stand
