Rifle Scopes 40 vs 20 vs 0

[Chris1972]

Pretty simple question but would you use 40 moa of cant if you know the most you’ll ever dial is 15 mil. I’ll just be 3 mil above center at 40 at 15 mil dialed elevation. (In theory)

This is on a ZCO so it has plenty of elevation available. The question is am i unnecessarily losing optical clarity when I don’t need to. Per the manufacturer this is nothing to worry about.

20 moa rail existing and a 20 moa ZCO mount in the way.

I can ditch the rail and get a 0 moa from Zermatt if needed.

I have the same question as I have the GenIII Vortex to mount on a 20 MOA rail and all I have laying around is an Audere 20 MOA one piece mount.
wondering if I should get another mount or just run it.
Putting it on a PRS type rig

40 MOA total is perfect for a ZC527

Depends on you and the scope used honestly...

Some scopes image quality is noticably worse at the extremes some scopes you don't see it.

 

[Chris1972]

That’s good to know.

Depends on the rifle and the use.

I use a ZCO 5-27 and have a 30 MOA rail on my AXMC and 0 MOA in the mount...pretty sufficient for my needs.

On my Anschutz 22, I use an S&B PMII 5-25 and have a 25 MOA rail and 20 MOA mount since I need all of the elevation I can get. I can reach 400 yards and the reticle gets me to 500.
