If your 100 yard zero is at the bottom of the scopes adjustment, you should have waaaay more than 45moa 'up'. The scope has a 30mm tube so it should have about 80moa+ total elevation range (40 up and 40 down from center).
I have the Bushnell 3200 fixed 10x (Bushnell Outdoor Products
) This scope has a 1" tube and I have Burris Signature rings with the inserts that give it about 30moa of cant. It's 100 yard zero is about 20moa from the bottom of the adjustment range and that leaves me with about 60moa 'up' - I know this because I have tested it.
On another note, I'm curious to hear your thoughts on the short eye relief of these scopes. They both have 3" eye relief where most other scopes have 3.5 to 4".
