You won't have any issues with a Razor. I have 40 MOA on several scopes with less travel than a Razor zero'ed at 100 (Bushnell ET and a Burris XTR-II, my Razor is on a 30MOA base)
I have several rifles with 20 moa rails and 2 moa mounts and am able to get a 100 yard zero. Here is how my 6.5 cm AI-AT with S&B 5x25 is set up. I can still go down 2.1 mils so this leaves me 23.9 mile of travel up with a 100 yard zero
