Air rifle scope on high power rifle?

prangle

Someone awhile back said they use air gun scopes on hunting firearms(big recoil).Can someone explain that to me.

Seems I recall that scopes made specificallyfor spring-powered airguns have reversed threads because the impulse from the spring is forward instead of backward & this keeps them from shooting loose.

On an air rifle the recoil is not straight back. The gun vibrates from side to side slightly. This causes the parts to loosen. On magnum firearms the recoil is straight back. Also on a air rifle scope the focus range is set for closer targets than a normal scope. Kgun

Guns & Glass

Air rifles, more specifically spring/cylinder type have two forms of recoil forces, positive & negative. As the spring/compressed air charge is released, the spring flies outward at high speed, to a full stop almost immediately, then almost immediately bounces back to uncocked position. In a fraction of a second.Think of sitting on a rocking chair/car that accelerates to 25-40mph moving forward, immediate full stop, immediately rocks backward, stops, and vibrates.What would your neck (the reticle)etc., feel like?That's what happens to air rifles, and the mount system. Scopes must be built differently to handle the "G" forces if they are to be reliable.Good ones will cost more.Most rifle scopes eventually won't hold up.Very, very few companies actually test for + & - forces. So, when you see advertising that reads "X amount of recoils of a caliber", and says nothing about 'negative' testing or testing for air rifles your not getting all the "advertising story".

While I won't go into the technical stuff, I very strongly suggest that you don't use air rifle scopes on big game (deer, elk, etc)rifles. They aren't built for the recoil. One time when I was on military advisory mission to Iran we had a big game rifle in the team house. The scope was not built for that application. After a few rounds the cross hairs fell out.
