Clearance between barrel and objective bell?

Just switched the scopes on a rifle and the objective bell on the new scope is awfully close to the barrel. It's not touching, I can slip a piece of printer paper in there easily.

The rifle is an 7-1/2lb. .308, do I need to be concerned?

Thanks, Rob

Not at all. As long as it's not touching then it's enough clearance.

Good to go for the range, at least.
In a hunting rifle, I like more clearing.
If the scope is very close to barrel, it will hold water, and twigs and shit that can alter point of inpact.

I would recommend a bit more than 1 thickness of paper. Barrels flex and metal expands when it gets hot and the last thing you want is your barrel and scope making contact.

I measured the thickness of paper that will just get through, I have .004" clearance and it's at the end of the breech, at the beginning of the conestaper, where I imagine there's no flex.
