Reply To: Trying to get a understanding….
Well I don’t agree with the choice of words “strike the wall and bounce forward”. But that’s close to what happens. When you pull the trigger and release the energy stored in the spring the spring weight and piston weight causes “some” recoil to the rear of the rifle. Then at some point that spring weight and piston weight comes to a stop(I didn’t say it hits the end of the tube but it does stop). This is the part that normal pb scopes don’t like. Its not much but some scopes want no recoil forward. The piston doesn’t have to hit the end of the tube for some energy to show up as forward recoil. Many air gun scopes have etched glass reticles since wire reticles have trouble with the forward “bump”.
I have a Benjamin Trail XL 1100(not a rifle that sees much daylight) that there is no doubt what it is doing to a scope. Its way past the “bump” stage backward and forward.
