Scope Bell Touching Barrel: "Yea" Or "Nay"?

[lewwetzel]

Not even a teensie weensie bit? Just tried mounting scope on new rifle. Rings seem to come to full clamping pressure just as objective slightly makes contact with barrel. Pulled back off and no ring marks; side-focus knob turns like there's no binding. Really don't want to go to next ring height up. Light-recoiling .204R. Do I dare?

Nay...

The vibrations will kill the scope.

Use some shim stock..( say .020 thk) under the mounts on BOTH Front AND BACK raising the scope equally to get it to clear.

Was thinking of trying that.....thanks.

I always thought you needed at least 1/8" between the bell and barrel.

Nay!!!

Nothing should touch the barrel. What about sliding the scope forward enough in the rings to get the clearance you need? The little bit of movement might not make too much difference in the eye relief.

Nay on bell touching barrel and using shims (sorry not a big fan; can result into trouble later).

IIWY, I'd replace proper ring height or base to achieve proper clearance.

If I am going to be shooting against you in a match go for it.

Wish I could, as the barrel taper would buy a tad more space. Only trouble is, the scope's as far forward in the rings as it will go; ironically, it has enough eye relief that it could otherwise move up with no problem.

Ha ha!

Looks like the prudent thing to do with this 50mm obj. scope would be to just go with higher rings (in this case "ring mounts" as this is a C-Z and the selection is limited; the DIProducts pic rail conversion that would enable using a plethora of regular Weaver-style rings is backordered ). Or I might just modify the bolt handle and go to lower rings/smaller objective scope for better cheek weld.
Thanks, all.

Nothing a dremel can't fix

NAY! as stated above it's a BAD idea.

watch an ultra slow motion video of a rifle shooting the barrel moves more than you would ever expect. if you don't have at least 1/8 I would change the mounts and everything until you can make it right.
