Something is definitely not right with my scope

[Klenchblaize]

“Upon recoil that scope could hit the barrel, seen that before and is not good for the scope.”

I think this observation could do with a little more detail please. As in what is moving during recoil?

If I fit a flip-up objective cover to one of my rifles it makes contact with the barrel to the point of an interference fit but has zero impact on the ability to shoot 10-shot ragged hole groups from the bench at 100 yards.

Of course it helps that it doesn’t have mounts & rings made of Texas but rather material designed to conetrol movement!

Yep. It can. If the barrel is made of cheese . . .

No it is made of similar material that springs are made of. Scope Aluminium has roughly one third of the stiffness of steel. Lever length does the rest.
BTW I said it could and I have seen it happen in the past. I would mount a scope with 2-3mm clearance min, you can mount a scope closer.

If it's mounted correctly it just won't happen. Barrel flexing is the nature of the beast, but with correctly mounted optics it's just not a concern

 

[Klenchblaize]

Of zero use to the Op but I recall shooting along side a chap with one of the below target scopes installed on a 308. Each shot was followed by the loudest and weirdest ringing sound you’ll ever be subjected to as the vibration from recoil transferred through the scope and visible pressure retention spring:

I’m certain other SR&PC members who shot at Shoreham Range will recall this piece of firing point ‘entertainment’!

Part of correctly mounting a scope is to have certain gap between the scope bell and the barrel. Just to avoid contact upon recoil. Nothing is ultimately stiff.
Every ones level of "correctly" mounting a scope differs that is why we have threads like this on a forum.

Great pun BTW (designed to conetrol movement!).

I guess a lot also depends on calibre, barrel profile, etc, right enough.

Mounting your scope close to the barrel is not a benefit!

It will mean the moderator obscures half the objective lens and disperses mirage over the sight plane of your scope, this is NOT a benefit!

Additionally, it will make fitting objective covers difficult, and in extreme cases can cause the scope to be bent.

My scopes are all nearly touching the barrel and I certainly do not see the mod in the sight picture with any of them and all I do with the covers is take a slot out of the bottom

Upon recoil that scope could hit the barrel, seen that before and is not good for the scope. S&B scopes often have issues when they run in the red area of the posicon. Try reversing the mounts as others said. I would toss em in the bin and get a Spuhr one piece hunting mount that goes on the rail. 0 MOA as S&B Zenith don't have huge travel. Sometimes one runs into issues with 20 MOA setup.
I also saw the H... Hinten? Rear.

ps, worst case one can measure the distance of the scope tube from the top of the T3 action, front and back.

How does that work then ? No way the barrel can hit the scope

I know, it‘s a .50 BMG, but I think you will get the idea …

The recoil from that is a different league it will not flex like that with a conventional cali

You own a high speed camera?

Look down a line of any half decent target shooters and there is no one following the 'as low as possible' cult of scope mounting.

If mirage was not an issue, mirage bands would not exist.

Any scope that goes down to 3x or so will result in the field of view being restricted by the moderator. Another consideration is glare from the mod/barrel during night use.

Yes and no, acceleration of a rifle upon recoil depends on the recoil of the cartridge and the rifle weight. Have a cartridge with 1/3 of the recoil & 1/3 of the weight and you are at a similar acceleration. Scope weight vs scope mount system. The 2.5-10x56 Zenith is probably around 800 grams vs 1100grams of the 5-25 pictured in vid. Mounts look twice as strong.

We will have to agree to disagree as I said I never have that problem with any of mine

Show me a film of it happening with a 308 and I will believe it. All my rifles are around 1mm from the barrel at most and have never had any damage to any scope

 

[Steff]

I also like ‘em low, but not to the last mm above the barrel. I think the lowest I ever had was about 3mm and I had no issues. But if the scope cover starts to touch the barrel, as described by @Klenchblaize, this is something I would definitely not want.
As I mostly use 42 or even just 36mm scopes these days this has become a non-issue for me anyway. There’s simply no way I could mount them this low on my rifles.

i agree with you fully

Why should I? I believe in physics and as a design engineer done plenty similar calculations before. You on the other hand do not need to believe anything and can do your own thing. No need to veer on the safer side.
