[QUOTE="MontanaRifleman, post: 861362, member: 11717"] You will find that every scope is a little different when it comes to advertised and actual vertical adjusttment. Example, my NF 5.5-22 has 98 MOA of total travel while my 3.5-15 has 115 MOA, both advertised @ 100 MOA. Also, if you have say 100 MOA of travel it doesn't mean you will have exactly 50 MOA of up or down from center/zero and when you zero your rifle, you will loose a few MOA of up. Aslo, not all bases are EXACTLY 20 or 30 or 40 MOA as advertised and the machining of the receiver might have an affect on that as well. The safest thing to do is leave a little fudge room. With my 300 RUM I am mounting a 40 MOA rail to use with the 5.5-22. I should have about 80-90 MOA available in total up adjustment from zero. IMO, a 20 MOA rail might work if you want to shoot the RUM past 2K but you might be be cranking close to the edge of the travel with the Razor. If you can get the 230's going @ 3200 fps with RL33, which is optimistic, they will be going subsonic in the 2200 - 2500 yd range and you will be needing about 70 -75 MOA of up correction. And more for less MV. [/QUOTE]
