Leaving a gun cocked...

Jump to latest Follow Reply
Can't imagine why anyone would want to leave any gun cocked and loaded while in storage...doesn't sound like a safe habit to me, and wouldn't the small hammer spring in a pcp take a set the same way a giant spring in a springer pellet gun does when left cocked for extended periods of time? Unless I fear an attack by rabid killer rabbits at night while I sleep where I may not have time to cock my Wildcat, I think I will leave mine uncocked when not in use for safety's sake. :)

Who said the gun is going to be left cocked and loaded while in storage?

"and wouldn't the small hammer spring in a pcp take a set the same way a giant spring in a springer pellet gun does when left cocked for extended periods of time?"
A spring "sets" when it is compressed beyond its yield. You can easily avoid this with a small hammer spring, but it would be harder to do in a springer. In order to build a springer with a spring than "never" sets, the spring would probably have to be way bigger, longer, thicker, or what not, to avoid "setting", which in return would mean a heavier, clunkier gun. I guess. No expert on this, just using common sense and taking an "educated guess". Just think of a car. I have never heard of springs on a car going bad, and they are compressed for years. The trick is though, to not compress them past their yield.

"Imold"I leave mine un cocked and with about 190bar in them or full, heard it was a good thing to do for the seals and haven't had a issue yet but I did leave my one springer cocked and loaded for a while as I was trying to get a problem 4 legged beaver. Finally took care of him at night with my 30-30, she was about 65lbs when I got her out of the pond.

From my understanding this is correct. You are supposed to leave air tanks and air rifle [tanks] under pressure when stored... I do the same.
How long was your springer cocked for?

Thanks,

I wrote an email to FX Airguns and here is their response:

Hi, I am wondering if it is going to "hurt" my Bobcat MK2's hammer spring (or any other part for that matter), If I leave it cocked for an extended period of time.Quote:

Hello Sir,


It is ok to leave the spring cocked for longer times for the springs but I would never recommend it.

we have tested having it stored in the cocked position for a couple of weeks with not seeing any bigger differences.

But as I stated earlier I would never recommend it as other parts in the gun can be hurt by it.

End quote.

I responded to the above email asking:

Thanks for the reply. Do you mind telling what other parts "might" get damaged when leaving a gun cocked for a few weeks?

Hello Sir,

leaving the gun cocked for prolonged times could hurt the trigger sear.

That being said, I have never received a trigger sear that has been broken by prolonged spring tension.

I guess this answers my original question. : )

Thanks,

Kmd

evidently some guns(from certain manufacturers) dont follow the laws of physic lol



have you slept on a spring mattress which was compressed permanently, or when a fat person drives a car long after years even a light next driver sits lower than the other passangers.



of course it will accelerate the wear, and tear, aging/deformation process!!! by the way some speciality spring manufacturers offer pre compressed/pre set springs if you did not know that...



not saying it will break, but it WILL deform over long period of time. fatigue does happen after repeated stress even bellow yield point. also do not forget the helical spring is stressed by torsion too. hammer springs especially are compressed a LOT.

as long as they are available, cheap to get who cares

This is what causes the "wear" to a spring. The mattress is caused by getting in, then out of the bed, rolling around.....repeatedly. Coil springs on cars "wear out" too, it's not caused by the cars weight "sitting" on the springs while motionless, it's from the car going up and down (wheels going up and down) during use.

Well, I can give you an example that extended periods of time have no effect on hammer springs that are compressed, but not fully cocked. The used .25 Cricket I recently bought had sat around unused for about 3 years. In Crickets, the hammer spring is under tension (partially compressed) when the gun is not cocked. In fact, Charlie Freer of Georgia Airguns, one of the best Cricket tuners that I know of, recommends removing the hammer spring when storing the gun for more than a week or two. In the Ernest Rowe tune January 2015, the velocity with Kings was about 955 FPS. When I checked the velocity last weekend it was about 960 FPS with the same JSB Kings. Food for thought...
