Trying to get a understanding....

The laws of Physics never change. F=(mA) I am assuming you are talking about the part of the article in reference to springers and scopes? Now if your asking if MFG's are now all designing their scopes to be airgun worthy. I can't answer that definitively but as I understand it you still need to choose a scope that is rated for airguns, especially springers. Hope that helped.?
F=force
m=mass
A=acceleration

The article you quote is basically correct but in places is built on 'received' internet wisdom, mostly for a quick catchy webpage, I imagine.

The single most important factor when considering a scope for a Springer is the TWO WAY RECOIL - pretty much all scopes can handle a one way push, not many can take the very rapid deceleration then counter recoil that a springer provides.

The Laws of Physics (prob. a few hundred year old Physics) tell me :) that a lightweight scope capable of being mounted low to the receiver, with few 'moving parts' (read anything 'adjustable' apart from the crosshairs / turrets) will be the best choice.


A quick saunter thro' my Springer scopes in constant use reveals 2 Leupold M8 4x32s, 1 Simmons WTC 1.5x5 28 (is it?great little scope)

All are small, lightweight and simple.

4x32 is STILL the very best scope parameters/option for Springer owners who hunt (IMO).

OH,

and !!

On a Springer

The piston does NOT meet or clash or hit the transfer port area of the receiver (unless some clever dick has been at work with a dremel) - it cannot (Laws of Physics) Air is an elastic substance it cushions the cylinder at the extent of it's travel because it cannot escape fast enough out of the transfer port and barrel.

So, on an 'unmessed with' Springer the piston will not clash with the receiver end EVEN IF YOU HAVE FORGOTTEN TO PLACE A PELLET IN THE MECH. - granted, it wont do your rifle any good to do that (Dry Fire) but it wont do any immense mechanical damage, it cant.

'oldspook' that's largely an Internet myth and it suits airgun makers to not contradict that myth.

I have not said that it is 'A Good Thing' to do, or is wise, but any (honest) long time owner of a Springer will have done it accidently and seen no major problems.

The Piston CANNOT clash with the cylinder end on an unmessed-up airgun - the air cannot escape quickly enough NOT to provide a cushioning effect.

This point has been made by me and others many times - asking for evidence of any damage.

None has been shown (for a rifle that has not been either 'modified'/bored out, or has completly failed piston seals/rings).



Dry Firing a Springer will cause excessive strain on several components but will not result in the 'car crash' scenario people like to talk about. (Laws of Physics).

Yeah the only thing I could think of that dry firing a springer would do is possibly form the piston buffer to the cylinder faster ...Whether that's good or bad is hard to say . A piston firing under spring pressure , I can't see how a TINY piece of lead could be cushioning the fall ...I don't do it to other guns but I dry fire my personal gun without a thought

Well if you insist on evidence. I had a lovely Beeman R10. That was a fine rifle. One day a friend came over. He dry fired it. It broke the spring. I mean the gun was dry fired one time and it broke the spring. Around that time I bought a Diana Model 48, one of the first ones made. A decade or so later I made the mistake of dry firing it when a pellet dropped out of the barrel as I was closing the chamber. It broke the spring. I have a D460 in which I was shooting very, very, heavy pellets last fall while I was testing. It bent the spring. We have since replaced the spring. I'm going to call that evidence shown. Since I knew these things before there were anything like these forums on the Internet, I have to say, I don't believe it is an Internet myth. Additionally you assert that this "myth" somehow benefits the vendors. Tell me, "How does it benefit a vendor to have a limitation of the product widely published?"

Actually, I'm new here and don't want to step on anyone's toes, but to be honest, I have never heard anyone in any forum ever make the assertion that damage from dry firing a spring air rifle won't likely be catastrophic. In my case it has almost always been catastrophic. I think it is irresponsible to promote such obvious balderdash to new shooters who may not know better. While we are at it, what is your opinion of deliberately dieseling a spring air rifle?

Now about physics, I don't have a degree in physics. What University did you attend to get your physics degree? I am interested because while I never did real physics, I've written a few million lines of code for DoD that simulate real physics...

http://www.arld1.com/pistonpelletdynamics.html This will help if you feel like a very informative read.

It takes something between fifty and a couple of hundred PSI to push the pellet into the forcing cone and engrave the rifling. That pressure has to exist *before* the pellet starts moving down the barrel.

well good luck Major, there's nothing 'secret' or especially difficult in finding a good Springer (rated) scope as most have been around for a while - look at what other Springer owners are using.

I come at this from the viewpoint of a Hunter not a Target shooter, hence my advice on 'small and simple'. Target shooters are in a rarified world and in the area known as Recoiling Rifle (airrifle) a good proportion use rifles with mechanisms designed to counteract recoil. They are also 'rarified' in being able to justify $1,500 scopes to themselves (or their Home Accountancy Expert - not sure how, I do wish they'd pass on that info :) ).



Here's the particular section of your link (in the OP) that gets' my goat...

"As the spring and piston are moving forward, the gun is recoiling back against your shoulder with significant pressure. Now here’s the part that many people don’t understand. As the piston comes to the end of the compression chamber it will actually strike the wall with substantial force, and the gun will now bounce forward, recoiling away from you".

That is his description of the Normal Firing of a Springer BTW - it is also completely and totally wrong.


Ignore some stuff you may read on the WWW.

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.
