It started more like this with scope firmly against it.
View attachment 523577 You think that the pellet is going to stop it?
Or does it get sheered off?

@20calguy - Friendly observation. Take it for what it's worth:
Several years ago, one of the more seemingly knowledgable guys on the list advised somebody that when he mounted his scope to his springer, to put the stop pin in the hole and then slide the mount FORWARD as much as possible before he tightens it to prevent it from slipping forward.
If you think about it, if you are assuming the greater recoil is the first recoil backwards into your shoulder, that should move the scope forward if it's loose.
Inertia would make the scope want to stay in place as the rifle recoils backwards underneath it, thus making it creep forward.
You have the opposite problem, just like I had with our HW97K. Our scopes slipped back - indicating the second recoil forward is the stronger recoil.
Mine was, and continues to be, so much stronger that it's literally broken the welds that attach the barrel assembly to the receiver tube three times so far.
Yes, it's literally broken our gun apart three times.
So, I could be all washed up here - I'm not the brightest boy in the world, and my thinking hasn't been as great as it could be lately - but it sure seems to me that your problem is with your forward recoil, from it not having proper air cushioning. And I don't know how your 35E is engineered, but you might want to at least examine it to see if there's anything it might break if you don't address the issue sooner rather than later.
Ours broke some sizable welds. These springers have some pretty considerable forces in them.
If you were to fire your springer without a pellet in the barrel, the piston slamming forward would be very much like giving the breech of your rifle a good hard smack with a hammer. If you have a leak or some other mechanical problem going on, that is essentially what you are doing every time you fire your rifle.
Or so it seems to me, for what it is worth.
Just a friendly observation. Forgive me, please, if my thinking isn't right here.
I don't remember where you bought it from, if you've ever said, but if you bought it from AOA, you might want to give them a call and see if you can send it back for them to look at under warranty.
