Thread: How close is too close! Objective bell to barrel.

If you can just pull a patch through the gap, it would be no more than 1.5mm clearance, possibly only 1mm. You have a short scope overhang from the front ring and from what (I think) I can see of the barrel, it doesn't look to be a soda straw. With more overhang and a thin barrel, there is every chance that barrel whip under recoil could contact the scope which isn't ideal.

I once ran 35 thou of clearance with a 1.25" target barrel and got away with it but that was pushing it in my estimation.
