Dont take this to the bank - its your scope and your call.
The Leupold mounts are good, but have a 1;4 type split ring. The upper piece of the ring goes just over centre on the tube. IE it wont just slip on - it snaps on. Frankly this still brings me out in a cold sweat for fear of marking the tube. When Byron did some filming with me ages back, we fitted a brand spanky new top of the line Z6i Nutter Turbo etc into Leupold rings. We drew straws for who was going to do the deed and cold sweat doesn't begin to describe it! But on they went - with a nerve shattering 'click' and off they came - no mark - phew!
It helps to lightly lubricate the tube and ensure the rings aren't stone cold. Support the tube in your hand - less likely to stress it - and apply firm steady pressure to the top of the ring.
Ultimately, no mount worth risking a scope for. If in real doubt, swap the Leupold for 50;50 split rings like Warne etc.
Good Luck!
