Rifle Scopes Least stressfull possesion for erector springs when long terme storing

[Peter83]

Hi guys My hunting rifle with a Burris XTR II 5-25x50 is going to be stored for some time without use. A buddy reminded me it could be a good idea to dial the scope all the way down ( in this case clock wise like when dialing POI down ) i tried this, but the clicks seems to getting stiffer / harder when dialing clockwise all the down, and dialing all the way "UP" seems to make the clicks lighter to make. I always thourgt, that dialing all the way "UP" on a turret made the spring(s) compress, and dialing "DOWN" made the springs sit not compressed. What is right?

Best regards

? Just leave it zeroed.

I would still like to know , even if i do leave it zeroed

I don't know where exactly the springs in the XTRII are. A lot of scopes use one spring at the 7:30 position. The original XTR went to a 2 spring set up, I assume one on the bottom of the erector tube and one opposite the windage knob. I have read the XTRII has 3 erector tube springs, as to their location I am not sure.

@koshkin may be able to shed some light.

Thanks But generally speaking, dialing a elevation turret "up" would compress a erector spring, right?

I am not a scope expert but I always thought the erector spring(s) were opposite the turrets. This would mean dialing down would
Compress the spring more.

You realize they test these things for gazillions of revolutions up and down during development right?

Springs wear out from winding/unwinding not from holding a load. Just turn it to zero and worry about something else, like which bathroom you should be using based on your lifestyle.

Springs don't "wear out" or "lose tension" just being stored under tension or compressed. What wears out springs is the movement from compressed to uncompressed to compressed, etc. Ever bend metal back and forth to break? Same principals. Ever notice how much heat it produced when bending that metal to break?

I guess you keep all your magazines unloaded as well. Dang.

I recon that depends on which spring and where it is.

Ok, i leave it zero. Thanks all ;-)

Springs wear out from winding/unwinding not from holding a load, some have gun mags loaded to the max for long extend of time, like 20-30 years, put the mag into the gun, all functions fine, no jam at all.

Someone said erect.

Springs don't lose preload via plastic deformation (the technical term for "taking a set") from sitting compressed at reasonable temperatures. They lose preload via fatigue from an excessive number of cycles, or from exposure to temperatures high enough to cause creep. So, yes, attempts at avoiding spring set by backing off on the spring - whether it be in a magazine, or torque wrench, or I guess now riflescopes - actually makes the problem worse.

A property designed spring can be left in any position for any amount of time without concern for its health.
