Extra cant for ZCO420?

[Beasler1]

I have a shiny new 300 Norma Mag barrel for my DTA SRS A1, and I'm going to mount up a ZCO420. Other barrels I have for the rifle are 338LM, 300WM, 6.5CM and 308. With the 120moa of overall travel in the 420, and a maximum shooting range available to me of 1200 yards, I don't think I'll need any extra cant in the mount. But, would it be advantageous to get a +20 mount? It looks like I would still be good at 100 with the +20, but I'm just not sure I need it. Same price either way ... just looking for the most practical overall choice for the system.

Thanks Fellas

Thanks to Richard at CSTactical for the guidance.

I'm going with +20

You can easily run 40-50 moa of can't with the zco in case anyone was wondering and still have a 100 yard zero.

For anyone, Spuhr made a 55moa just for these situations. I run one on my SRS and it's awesome. I have 32 mil of usable elevation.
