Rifle Scopes space between scope and barrel?

[Whit]

I am not sure where to post this, but since it had to do with mounting a stop I picked here.

Is there a set minimum space between the barrel and scope? I have about .025 using feeler gauge between the barrel and lens cap, and about .065-.066 without the lens cap. Is that enough space? This is on a 338 Lapua.

I was always under the impression that as long as they do not touch it is okay.

I thought the same thing but I want to double check. I am dealing with a 338 Lapua and a Nightforce scope, I don't want any errors.

I was thought the closer the better. As long as they are not touching.

Some say as long as they dont touch theyre ok, but i had a nf mounted about the space of 2 sheets of paper, when i took the scope off after being shot several times i had rub marks, where the barrel and objective met. This was with a badger base and badger rings

Here is a couple pic of what it looks like. I taped a piece of white paper behind it so you can see it better.

I have a badger base (20MOA) and rings too.

You are probably fine with that set up.

You will probably be ok. But if you want to check it take the scope off put some white chauk on the barrel replace scope and shoot if bottom of scope picks up chauk it's too close.

I have seen that video before, that is why I am asking. The 338 Lapua doesn't have as much recoil as the 50 BMG, but again thats why I am checking.
